How to fix trellis to a wall

Trellis is a very effective way of training climbers against a wall and can either be bought or made from scratch. Fixing it to the wall though can present problems but with a little care result can be both durable and effective.

Equipment:

  • Drill driver
  • Heavy duty SDS masonry drill and bit
  • Plastic wall plugs
  • Wood-screws
  • Spirit level
  • Claw hammer

Method:

  1. Choose a wood-screw about 50 mm thicker than the trellis, more if the wall is rendered, and some plastic wall plugs recommended for the size of the wood-screws.
  2. Fit the masonry drill with a bit the recommended size for the wall plugs, you may want to hire a drill in (a 4 Kg drill which takes SDS drill bits will be sufficiently large).
  3. Position the trellis where you plan to have it and drill through the trellis into the wall. Chose a place half way across the trellis and near the top. Always aim for the centre of a brick or stone, avoid mortar joints.
  4. Move the trellis and tap a wall plug into the drilled hole. Put the trellis back and thread a wood-screw through the hole you drilled in the trellis and into the wall plug. Tap the screw head to start it off and drive it almost home with the drill driver. Check the trellis is level and vertical, the first screw will support it, and tighten the screw until it is flush with the trellis surface.
  5. Drill a second hole through the trellis vertically below the first and near the bottom; checking the trellis is still level and vertical. Push a plug into the hole, there is no need to move the trellis, and use a wood-screw and hammer to drive the plug into the wall until you feel the screw bite into the plug. Tighten the screw with the drill driver.
  6. Carry on repeating the process in part 5 above so that the trellis is screwed to the wall every 600 to 900 mm, checking the trellis is firmly attached to the wall.

Actinidia kolomikta

This beautiful wall shrub deserves to be far more widely grown yet currently only about 53 suppliers are listed in the RHS plant finder. This is surprising as few other wall grown plants provide such an attractive display for so long. The foliage opens green but quickly develops a white and pink variegation as if they had been dipped in pots of white and pink paint. This variegation only develops in the presence of plenty of sunlight and along with the shrubs scrambling habit means it is always seen grown against a south facing wall, although I can imagine it would also be very attractive scrambling over a south facing bank.

It’s white, slightly fragrant, summer flowers are over shadowed by the foliage and as it is both dioecious and it is only the male plant which appears to be in cultivation you are unlikely to see the fruits which are said to be edible. The closely related A. deliciosa (A.Chev.) C.F.Liang & A.R.Ferguson which is better known as the kiwi Fruit and several of the 100+ species of Actinidia Lindl. are cultivated commercially for their fruit.

Actinidia kolomikta (Rupr. & Maxim.) Maxim. is easy to grow not being particularly fussy as to soil type and vigorous, reaching up to 4.5 to 6 metres up a wall. They are reasonable easy to propagate by cuttings or layering and are perfectly hardy.

First described by Carl Johann Maximowicz and Franz Josef Ruprecht two botanist working in Saint Petersburg in the 19th century; they initially placed the plant in the genus Prunus but subsequently both revised their decision and Maximowicz placed it in the genus Actinidia created by the British botanist John Lindley which he named after the Greek for ray because of the styles in the flowers. The plant is native to the region of Amur in Russia where it is known as kolomikta and Maximowicz described the plant growing wild in his 1859 book Primitiae Florae Amurensis (Beginnings of an Amor Flora). Amur Oblast is still a largely remote region with temperatures that can range from above 30°C in summer to below -40°C in winter.
