A quick guide to installing your Living Walls instant hedge into areas where root growth is restricted, such as in containers, raised planters, planter boxes, and retaining walls, is below.
If you are employing a landscape contractor to install your hedge, please forward this guide to them.
Please check measurements before planting as all quoted measurements are approximate.
1. Choose your planter. Our instant hedges are grown and sold in one-metre lengths (foliage), with the rootball approx 900mm long. Ideally, enclosed containers should have minimum internal dimensions of 900mm L x 500mm W x 500mm H for a 100L hedge bag option, 900mm L x 400mm W x 400mm H for a 70L hedge option. For longer containers or planter boxes intended to contain multiple metres of hedge, ensure any cross bracing is placed at intervals that minimise rootball disturbance, e.g. at one-metre centres.
Ensure your planter has adequate drainage, as plants may not thrive and may even fail in saturated mixes/soils (i.e. drainage holes for containers; planter boxes open to free-draining ground).
2. Prepare your planter. Use good quality container mix for enclosed containers, available from your local garden centre, beneath and around the rootball. For planter boxes that are open to the ground, you can use either quality garden mix or topsoil.
We do not recommend amendments such as scoria, compost/sheep pellets, water crystals, or fertiliser in your planter. Scoria does not improve drainage; compost breaks down, causing plantings to sink; and fertiliser should be top-dressed only (scattered on the surface).
To calculate how much container mix you will need, work out the volume of your enclosed container. Multiply the internal measurements, e.g. 1.000 x .400 x .400 is 160L, and deduct the volume of the rootbal,l e.g. 70L, so in this example you will need approx 90L of container mix per container.
3. Place out then remove the hedge bag. Place hedges near your planter with logos facing the same way. If we have numbered your hedge bags, then place the bags in numerical order left to right. Cut out the two square ends of the bag and lift the hedge into the trench. You may like to use the bag as a sling. Avoid kicking or roughly handling the rootball, as this will weaken it.
4. Place instant hedges into your planter. For multiple unit planting, place the hedge rootballs approx 10cm apart for one unit per metre. The foliage will be touching but not the rootball (see diagram below). Remember, the rootballs are approx 900mm long, and the foliage covers the full metre. Please check measurements before planting as all quoted measurements are approximate. The hedge bag handle is one metre long if you need a guide. Only cut the rootball if necessary, e.g. when a part metre is required. Cut between the plants leaving a much of the rootball intact as possible. Use a saw rather than a spade as this will reduce potential rootball damage.
5. Backfill. Before backfilling, settle all of the units into place to your liking. Backfill halfway with your mix packing it firmly between and around the rootball, but do not overly compact it. Water between and around the rootball to help settle the backfill. Complete the backfilling to the same height as the top of the rootball. Water well, immediately after planting. See here for ongoing watering requirements.
6. Trim. If required, lightly trim your new hedge to shape. See here for ongoing trimming requirements.
7. Feeding and Mulching. After planting apply fertiliser by scattering a complete NPK slow-release fertiliser around the base of your hedge. Add mulches of coarse organic matter or other materials to help reduce water loss and control competitive weeds. Do not build the mulch up against the plant trunks. Do not use green grass clippings. See here for ongoing feeding and mulching requirements.
8. Enjoy. Now stand back and enjoy your new hedge.
