General garden tips
Label plants with plain plastic labels and write on them in pencil – because pencils do not use dyes they do not fade in strong sunlight and the labels can be cleaned and reused.
To tie a plant to a support cut off a short length of soft garden string, tie it around the support with a single knot and then tie the two ends of the k not around the stem with a
double knot but leave space for the plant stem to grow.
To keep you hands warm wear a pair of thin warm knitted gloves next to your skin and then a pair of hard-wearing plastic (nitrile) gloves over them. It may seem cumbersome but it works very well.
To sow very fine seed mix it with very fine dry sand to bulk it up and so you can see where you have sown the seeds.
Machines like vibrating plates used to compact hardcore only compact down to a depth of 150mm (6 inches) and so if building up levels with hardcore spread 150mm, compact it then repeat the
process until the desired level is reached.
