Hedges

How do I plant a hedge and what plants should I use?

When purchasing hedging plants from nursery or garden centre, ensure that the plants if grown in pots are not ‘pot bound’, that is the roots have not distorted their pots by bursting to get out. That they are of a uniform size in height and bushiness and they are not full of weeds and dried out. If purchasing bare-rooted ensure the root ball is moist and the plants stems not broken.

The site for planting a new hedge will need to be dug by spade or rotavated before planting. The soil will no doubt need to be improved by incorporating old farmyard manure, the provenance of which will need to be ascertained, or proprietary or home produced compost. Dig out a trench of approximately 35cms. deep and incorporate the organic material. After this place a string supported by stout wooden stakes at each end of the line to act a planting guide. For a field or security hedge, a double row of around 60-100cms apart will be required, for a garden hedge a singe row. In either case, place the plants out at a distance of approximately 45cms, staggered between the plants for a double row field hedge. Fertilise the trench with 70 grammes of sterilised bonemeal per metre, or use a proprietary specialist tree and shrub fertiliser at the recommended rate. Rake in well. You may prefer top dress the finished planting with a fertiliser and allow the winter rains to wash in thereby providing a gradual release.

Backfill with the topsoil and vertically wiggle the plants to allow soil to work into the root systems, tread in and finally water in well and continue to water during dry spells in the spring and summer.

Golden rules

1. DO NOT plant in frosty weather-the roots may freeze and tear apart when planting.
2. DO NOT allow the plants to dry out before planting-soak overnight in a bucket if they have.
3. DO NOT dig out the trench too soon before planting-rainfall may fill the trench and possibly freeze ruining the soil structure.
4. DO water well during the spring and first summer.


Trimming.

A majority of hedging plants are best left untrimmed for the first growing season, except saplings of Cratageus monogyna (Hawthorn), Ligustrum (Privet) and Lonicera (Honeysuckle), which can be cut right down immediately post-planting. Trim hedges at least once per year cutting with the base of the hedge wider than the top. This is the best practice to ensure the maximum available light is to reach the bottom of the hedge, thereby assissting in making the bottom thick. If the hedge is to be layed, which is necessary to ensure a stock-proof hedge, allow the hedge to grow freely for two years before having it layed. An old and neglected gappy hedge, will have to be cut right down to the ground to allow re-growth.
