Choosing paving materials

With the vast range of possible paving materials it can feel a bit daunting when you first starting looking at paving materials. To try to reduce the selection down to a more manageable size, it is well to consider the practicalities imposed on you by what you are planning to use the paving for. You can then check how much of each type you are hoping to use, compare the costs of using different materials and if need adjust your plans.

Though there is considerable over lap; the uses for paving in a garden can be divided into four main categories: drives, patios, paths and utility areas.


When choosing a material for a drive the first consideration must be what will
happily withstand having a car regularly driven over it and parked on it. The second consideration, is that for many people it will be the first thing visitors see of there home. On the other hand though; it also spends a lot of time hidden under a car. Once you have eliminated the impractical options the chose comes down to cost and personal preference. Please note if you paving an area of you front garden planning permission may be needed.


Where as a drive is something you park a car on, a patio can be a major feature of a garden and so your budget should try to reflect that. The important thing  is that it forms an attractive feature and not a slab of paving.


The idea of a garden path is as old as the garden itself, but a path has to have a purpose.

And that will influence the materials used. If the path for instance is going to be in a vegetable, where you are stepping on and off the path onto the bare soil you are going to have problems if you use gravel . Every time to step from one to the other soil and gravel will be transferred from one to the other; ending up with a muddy path you can’t clean. On the other hand an informal border winding along the edge a border is going to be difficult to achieve with square and rectangular flags and runs the risk of looking messy if its full of cut flags.

Utility areas

Most gardens have some area dedicated to the necessary but unattractive bits of a garden where things such as the shed live. Here the importance has to be the functionality of the material. Something that is cheap, durable and easy to clean.

Paving materials


The trick when designing your patio is to make it blend into the surrounds while adding to them. To do this you are free to use every trick in the book. You can use materials which contrast with their surrounding or complement them but care should be taken when trying to match materials as a bad match can be the worst scenario. Nor should you restrict yourself to just one material as mixing in an additional material is a very good way to break up areas of paving and differentiation between different areas. Just don’t over do it!

Below I’ve put together a table of most of the paving/drive materials currently available, the list though is not exhaustive. The cost column is really only to give a very broad indication of the relative expense involved in using different ones The exact cost would depend on many factors including site conditions and how much if any of the work was undertaken on a DIY basis.

A patio to eat out on

As foreign travel has increased, so has our appreciation of the continental lifestyle; and with it the idea that the garden can be an extension of the home. This has lead to an increase in the appeal of eating out on a garden patio. In itself the idea of eating a meal out in the garden is not a new one but it is only relatively recently that the patio has become an expected part of the garden. For its size it is the most expensive part of the garden and so some careful thought is need before you start to build one.

The first consideration has to be where to locate the patio within the garden and with the British climate it needs to be in as sunny a part as possible. The idea of shade from the hot summer sun is very appealing but in the UK you need to make the most of any sunshine. To sit out and eat you need somewhere that is very warm. To settle down and eat a meal means sitting in the same place for possibly an hour or more – cool will soon start to feel cold. Shady areas, that never get the benefit of the full sun, stay cold in the warmest of weather and so don’t get warm enough to sit for any length of time. If it gets too warm, and in a sunny sheltered garden this can easily happen, you can use large garden umbrellas to provide controllable shade. These have the advantage that they can be put up or down and move as needed; something which is not possible with other sources of garden shade.

Once you’ve found a suitable spot you have to consider the size and shape of your patio. You have to consider not just the space needed for a table and chairs but also people sitting at the table and moving around it. In practice this means ideally you need an area at least 4 metres by 5 metres. This may seem a lot but from experience I would strongly advise you to treat this as a minimum and only make the patio smaller if your garden is actually smaller than 5m x 4m. It may well worry you that the patio is going to dominate the garden; but in this case make the patio the feature of the garden. The other thing is the shape and so long as you ensure there is a 4m x 5m rectangle within the shape you can let your imagination take its reign. A plain rectangle can be visually rather boring and often too rigid. The easiest way is to unevenly extend some of the edges of the patio out to break up the straight edges. Do not be tempted to try to break up the paving with plant filled gaps. These soil filled gaps will invariably end up under table and chair legs which promptly sink into them – you will soon be out with some paving and mortar to fill them in.

Finally you have to choose a paving material to make the patio out of. To work the material needs to have a reasonably surface, be solid (loose materials like gravel never really work) and be sufficiently durable both to survive the weather and the movement of the people and furniture over it. That a side, there is a vast range of materials to chose from both natural and manmade.

Sitting out in the garden

One of the most popular pastimes in gardens is sitting out enjoying any warm weather the British climate affords us. At its simplest this could be just relaxing on a lawn, but soon you will be looking for something a little more comfortable. With this comes the decision – where to put the seat. A light wooden bench can simply be stood on the lawn and moved around as needed. This has the advantage that when it comes to cutting the grass it’s a relatively simple task just to move the bench to one side out of the way.  More substantial seating, or when you want to make a feature of the seat, a permanent base is needed to stand the seat on.

The first consideration when deciding where to put your seat is what is you going to use it for? Are you looking for a shady place to read a book, some where to sunbath or a dinning area? By now you should be getting to know your garden and the shade changes during the day and the year. Take a chair into the garden – any one will do – and try sitting in some likely spots. The world looks different when you drop your line of sight by 2 feet. Does it still feel like a good place to sit? Are you over looked (or overlooking)? Can you till see the view you were hoping to admire? Lots of questions I know but it’s easy to modify your ideas at this stage.

Once a suitable place has been found; the next things to consider are what style of seat and what you are you going to stand it on. The actual choice of style is largely a personal choice and most styles can look perfectly good in most settings; either by complementing or contrasting with its surroundings.  The range of different seats is vast but a few pointers are worth considering.

  • You get what you pay for. The better made the seat the more expensive it is going to be.
  • Hardwood is more durable but of course costs more.
  • Both wood and metal seats both need regular painting to maintain them.
  • Seats don’t have to be bought. Some very effective seats are homemade.
  • Garden seats can soon become hard and uncomfortable so do you need cushions?
  • Single seats never look very inviting in the garden; so generally stick to benches or use groups of two or more single seats.
  • A garden seat does can be made from all sorts of different materials.
  • A seat doesn’t need to be a conventional chair or bench – be imaginative!

When it comes to what you stand the seat on the choice is simpler. You can stand it one the soil or lawn; but the legs will tend to sink into the ground, and not evenly, so you will have to keep repositioning it. Also constant contact with the damp soil is likely to encourage rotting or rusting of the base of the legs. Bark has similar problems unless it is laid over a firm base, if just a porous membrane is laid under the bark the seat legs will tend to puncture it. Gravel has similar problems to bark and it also needs an edging to stop the gravel spreading about. That aside both can make a good base for a seat that is not being moved around as it is in use. The last choice is paving in its various forms and this is the most expensive. If the seating is going to be around a table, with chairs moving about as people sit and get up from the table, then a smooth solid surface is the only practical choice.

What to put in the garden

By now we’ve got the garden under control and we can take time to consider what we are going to do with it in the longer term. I can’t give a list of what to put in as every garden is different as are its owner’s needs.  What actually goes into the garden is going to be determined by the garden and the use you are going to put it to. It is inevitable some compromises will have to be made; so it’s worth considering who is going to use the garden and for what. Once you feel clear about this, comes the problem of fitting it into the space you have available. Only a very luck few space for all the demands that we will place on a garden. In addition to the size your ideas have to allow for nature of the garden and how your needs are going to change with time. Most commonly people remain in the same house 10 to 20 years and a lot can change in that time.

To start off make two lists, one of the characteristics of your garden and the second of what you what to be able to do in your garden, both now and in the future. In the first list you need things such as its rough size, its shape *, whether it faces north, south east or west**, is it fairly level or does it slope, is it shaded by buildings and trees, which parts get the sun and when***, is it sheltered, where are the inspection chamber/manhole covers, where are any existing things you want to keep, What is the soil like, …

The second list needs to contain things such as do you intend to eat out in the garden****, what a pond or other waterfeature, are you going to put play equipment in the garden now or in the future, are you going to need a washing line or rotary dryer, are you planning to grow your own fruit and vegetables, what areas are you going to need access to, what car parking/additional car parking do you need now or in the future, do you need a clear area of lawn to kick a ball about on, do you want to grow a particular type of plant,…


* Most people assume their gardens are rectangular, but in practice they never are and in practice are generally along way from being a rectangular.

** In the UK satellite television dishes point roughly due south.

*** In the summer the sun is much higher in the sky, but never directly over head, so things like buildings and trees will cast much less shade.

**** As a general rule, ideally, you need a paved area at least 4 metres by 5 metres for a modest garden table and chairs.

Cutting back – the plan

Before reaching for the pruning tools you need a clear idea of what you are hoping to achieve and in the context of this post it is a healthy plant which fits both physically and aesthetically into its location in the garden. It must not overwhelm the area around it or in the end look unattractive to the eye.

Pruning is not the easiest of things to teach, partly because of the different requirements of different plants but equally because it is as much art as science. To start with a few preliminaries:

  • Plants don’t always respond well to pruning – not all plants will come again if you cut into old wood, this includes nearly all the conifers but also a number of others.
  • Those that do, don’t always do as you expect – often a plant will respond to pruning by producing a mass of soft shoots rather than one or two useful ones.
  • Once you’ve cut it off you can’t put it back – so if in doubt delay cutting and then take off a bit at a time to see how it looks
  • Think ahead to prevent accidents – you would be amazed at the number of people who actually cut off the branch they are sitting on!
  • Make sure you are suitably equipped – as you will never make a tidy job using poor/blunt tools.
  • Plan first, act second – have a really good look at what you’re tackling and how your cuts are going to affect the plant before you do anything.


Plants which should not be cut back into old (brown not green) wood include nearly all conifers. They resent being cut back beyond their green foliage, except for Yews which can grow away vigorously from old wood. Botanists insist Yews are conifers but try as they might, from a gardeners point of view, Yews are not very good at being conifers.  Most deciduous shrubs respond well to being cutting back but more caution should be used with evergreen shrubs and it may be better to spread the work over a number of seasons. Some such as lavender is not worth trying so it’s a case of live with it or replace it.

Thought should also be given to a shrub’s value be it sentimental or otherwise. With any attempt to drastically cut back a plant there is always the chance it may not be successful so consider “what if I lose it” and moderate your actions likewise. For example on the one hand a choice tree peony which is slow and relatively unusual would receive the minimal of cutting back while on the other hand a Berberis, a very good garden plant, which is readily available and grows quickly can be cut back very hard safe in the knowledge it will probable quickly recover and if not it is easy to replace.  I’ve seen Berberis cut down to ground level and recover.

Feed for health

As I have said before, the vast majority of domestic lawn problems come down to its feeding. That is not to say you can’t over feed a lawn, most people will have seen a lawn scorch where a heap of fertilizer has been left on it killing it. I also remember reading a report many years ago that some golf greens had been fed so heavily that the soil they were growing in could have legally been sold as fertilizer! So what to do? Clearly feed the lawn. Yes, I know it will make the lawn grow more and it will need cutting more – you will still only get round to cutting it at the weekend anyway.

If you read gardening books they will tell you about feeding a lawn in the spring and autumn, with more nitrogen in the spring to encourage lush growth and less nitrogen in the autumn to encourage less lush growth. There is though a problem with this, we know nitrogen is one of the most important plant nutrients but, there is always a ‘but’, nitrogen is not held in the soil and we don’t actually have any usable method of measuring the nitrogen that is in the soil. The latter we can nothing about the former we can. If the nitrogen is going to be leached out of the soil quite quickly, and the interaction between nitrogen and the remainder soil constituents is a very complex one, clearly the answer is to feed the lawn a little and often.

How often? About every 6 weeks during the growing season is probable about right. As to what to use, well a professional groundsman will use a specialist turf fertilizer but in practice: one you are not going to have access to these and two: unless you are looking after something like a golf course it will make no practical difference. In reality any general garden fertilizer will do the job, the fact the lawn is being feed and feed regularly is far more important. This way the grass is going to be well feed and able to outcompete weeds and diseases. Thus you will be well over half way to a good lawn capable of putting up with the use and abuse garden lawns live with. That is not to say it will not need occasional treatments but these should be the exception rather than the rule.

Keeping a lawn healthy

Ideally a lawn should be cut three times a week and the height should be reduced by no more than a third at any one time. In practice the first is never going to happen in a private garden, but the later is a good rule of thumb. The grass cuttings, unless you are using a mulching mower, should be removed and the most practical method of disposing of them is to use your councils recycling facilities. Making compost from them may seem a good idea but, unless they are mixed with a lot of other compostable material, grass cutting will not make compost – just vile smelling goo! In the past it has been recommended that you use the grass cuttings as a mulch around plants. In small quantities this can work but is unsightly and if too much is heaped up around plant stems it can lead to the stems rotting and the plant being killed.

Weed or feed

As you keep cutting the grass and then removing the grass cuttings you are removing the nutrients (plant food) that the plants have taken up from the soil to grow. This means you are slowly starving your lawn and if you starve something – be it a lawn or a person – it will succumb to things like illness and disease. Most domestic lawn problems come down to nutrition. Gardeners will complain that their lawns are sickly and full of weeds but when you suggest they feed it; they throw their hands up in horror and complain that that will just make it grow more. Now decide, are you going to have a lawn or just do the decent thing and give it a quick death at the hands of some weed killer. Either way you shouldn’t be torturing it! If the grass is going to out grow the weeds and fight off the diseases it needs to be properly fed, I’ve never heard a doctor say the best cure for that cold is starving you!

Most garden centres, and the like, are full of packets of lawn food; nearly everyone combined with a selective weed killer. Invariably every last one saying it will convert that sad collection of grass and weeds to something fit to grace centre court. The truth is that the groundsmen responsible for areas of fine grass like that don’t use combined fertilizers and weedkillers. They use fertilizer and very occasionally separate selective weed killers. This is partly because of cost, why pay for weedkiller that you don’t need.  There is though another problem with selective weedkillers; they are not that selective. They are weedkillers – they kill plants – its just that grasses are less susceptible to them than the broad leaved weeds. There is no chemical to treat grass weeds in a lawn and they do occur.

Selective weedkillers work by being applied at just the correct rate, too much and you kill your lawn, too little and you achieve nothing. So why do the manufactures sell “weed and feed” to the home gardener? Partly is because by adding the weedkiller they can add value to the product and so hope to improve their return. But the manufactures should not take all the blame because gardeners see weeds and assume the thing they should do is use a weedkiller to get rid of them, and a combined weedkiller and fertilizer seems a logical thing solution. Now this is not to say selective weed killers do not have their place, they definitely do, but prevention is always better than cure.


Cutting your new lawn

Now you have got the garden down to grass you have time to get on with the other pressing jobs about the house while you think about what you are going to do with the garden. Obviously the new lawn will need some attention during the summer and not just cutting it – but we will look at that first. When you walk into the shop you will be presented with a bewildering array of options but they can be split up into a few simple choices. How do they cut the grass and how are they powered. There are several mechanisms which can cut the grass but here we only need to consider two types.

Cylinder mowers

These are the more expensive type and cut the grass by a rotating cylinder of blades over a fixed bottom blade, so they cut like a pair of scissors. The blades fixed around the cylinder form one of

the scissor blades and a fixed flat blade at the bottom forms the other half. The blades have to be kept adjusted so they just pass one another. Because the cylinder is horizontal the motor has to be mounted behind it needing a system of belts or gears to transfer the power between them; adding to the cost. Normally the mowers have a pair of rollers, front and back, to support it and the height of the cut is normally by adjusting the front roller. Cylinder mowers are more expensive to buy and maintain but give a better finish (the more blades on the cylinder the finer the cut – not the faster the cylinder turns) and last longer.

Rotary mowers

These cut by spinning a horizontal blade parallel to the lawn and the motor is mounted straight on top of the blade, with it just bolted onto the end of the drive shaft. This makes them cheaper to build but because the motor is running at full speed, to give the blade the speed to cut the grass, they tend to have a shorter live. Also because they basically knock the top of the grass off they do not give as good a finish as a cylinder mower. They are supported by either wheels, wheels and a roller, or air. Ones supported by air have a fixed cutting height while the others’ cutting height is adjusted by the wheels and/or rollers. The blades of the mowers are shaped either to blow air down to provide a cushion of air if this supports the mower or suck the air up to blow the grass cutting into a collection bag. Rotary mowers never pick up the grass cuttings as well as a cylinder mower, and are very prone to clogging if the grass is wet. Some mowers, called mulching mowers, are designed to chop the grass finely and return it into the lawn. These can work very well and save the work of disposing of the grass cuttings but only work if a little grass is being removed at a time, otherwise there is too much grass cuttings to be lost back into the lawn.

Petrol mowers

Both types of mower can be powered by petrol engines and these have the advantage that you don’t have the problem of trailing leads or recharging batteries. They do have a lot more moving parts, so the chance of them breaking down is greater, and they are more expensive to buy and maintain.

Eletric mowers

Again both types of mower can be powered by electric motors and these can be either battery of mains. With mains electricity you have the problem of extension leads trailing across the lawn as you cut it and the power loss with long cable runs which makes using them a long way from the house power supply impractical. Batteries on the other hand will only run so long until they need recharging which can take a long time and rechargeable batteries only have a limited life before they will no longer hold their charge.

Turfing a lawn

It’s often said that you don’t need to prepare the ground for turfing as well as if it is to be sow. I don’t believe this is the case as in both cases the better the area is prepared the smoother the finished lawn will be. Again the surface needs to be cultivated, raked and compacted as for a seeded lawn. Fertilizer should also be applied and raked in the same. The difference comes from then on.

The first big difference is if the weather turns bad grass seed will happily stay in the bag in a cool dry place until the weather improves. Turf will not. In summer turf needs to be laid they day it is delivered. The best policy is then to prepare your ground for the turf so ounce it is delivered you are ready to lay it straight away. Measure you area in square metres and decide if you are going to be able to lay it all in one go. Bear in mind a roll of turf is sold in rolls weighing about 20 to 30 Kg. That in itself may not seem that much but remember each roll has to be picked up, carried to where it is to be laid, positioned and unrolled. Be realistic about how much you or you and your helpers can do. Also if the area to be the lawn is very irregular it may not be possible to accurately work out the area. Turf suppliers do not take back turf once sold. It may well be best to order part of what you need, say half or two third, lay that and then order the remainder.

Now comes the job of sourcing your turf; there are two types available meadow turf and seeded turf. Meadow turf is a farmer’s field someone has stripped the turf off and the grass is therefore very suitable for grazing cows and sheep on. If you are planning to keep a sheep, and I can’t imagine why, meadow turf could be suitable but for a garden lawn it is a waste of money. Avoid it! Seeded turf is grass that has been sown using a good quality lawn seed mixture solely for the purpose of producing turf. This is what you want and there are many turf growers spread across the country. Go and have a look at what’s available, any reputable grower is only too keen to show you the turf they produce. It should be a rich green, the turfs a uniform thickness, width and length, and the turfs should hold together well. In the field it should look just like a really good garden lawn.

Laying the turfs


Once delivered you want to get straight on with the job; so it is best to get prepared before its delivered. You will need plenty of timber boards to work from as you lay the turf, enough to reach the full width of the area to be turfed plus sufficient extra to stretch from the nearest hard surface to the furthest part to be turfed. The other things will be stout gloves for everyone, a wheel barrow or two if you are moving the turfs any distance and a good sprinkler and hose – the last being essential.

Start nearest to where the turf is and unroll the turf in a straight line across the width of the site. At the end of the first roll butt the end of the next turf up to it and unroll that. Carry on like that until you have a row across the lawn. Now place timber boards onto this row of turfs and start the next row butting the turfs close together but start about half a roll in. This way you will stagger the joints between the ends of the turfs. Carry on across the area to be turfed in this manner keeping the turfs butted close together. Keep working off the boards at all times or you will sink into the newly laid lawn. If the edge of the lawn is not retained by paving or fencing finish the edge by running a row of turfs along the edge to form it. Avoid any short pieces of turf at the edge. Any gaps can be either filled in as you go or near the end, it’s a mater of personal preference. The best way I’ve found to cut them is with a strong replaceable blade craft knife, at least that way the fact it ruins the blade doesn’t matter.  Knee pads are also very useful, the more padded the better, but either way by the end of the day your knees are still going to ache, along with your back.

Once you have finished for the day you must water the turf really well. Set your sprinkler up and leave it on until the water has soaked through the turfs and saturated the soil underneath. This can be easily checked by lifting up a corner of a turf. DO NOT stand on the lawn once soaked; you will sink straight in spoiling the lawn. Keep the lawn really well watered until its established. This is easy to gauge by lifting up a corner, at first you will see the fine new roots growing on the underside of the turfs and then you will just not be able to lift up the turf from the soil. At that point it is established and can be treated as an ordinary lawn. You must not let the turf dry out. If it does it will shrink and no amount of watering will reverse that, you will be left with a lawn which is a mass gaps along the edges of the turfs.
