Any garden, large or small, will benefit from some climbers. Whether covering walls or fences, arbors or obelisks, or just weaving through trees and shrubs, climbers can create and enhance the vertical dimension of the garden, especially where ground space is limited. Climbers are especially useful for screening unsightly walls or fences or for softening stark surfaces, creating a leafy backdrop that blends in with the rest of the garden.
Sunny walls and fences are a bonus to the gardener as they offer warmth and shelter for less hardy plants, and support for shrubs with trailing or fragile stems. Most will greatly increase their average height when grown against a wall. Others may not need the warmth for protection but to help ripen the fruit. Sunless walls and fences need not be a problem as long as they receive some light. Many shrubs will thrive, and some even prefer the normally cooler conditions of such a site
Careful soil preparation should be carried out, digging at least to a depth of 25cm or more and mixing in good quantities of organic compost such as well-rotted farmyard manure, spent mushroom compost, garden com-post or a proprietary planting compost.
The wall shrub, when planted, should be at least 40-50cm away from the wall or fence to allow for growth of the stem and also to ensure there is a good supply of moisture for the roots. Feeding with a general fertilizer in the spring will ensure that the shrub has adequate nutrients for the coming season.
Most wall shrubs have the advantage over climbing plants by being able, with a little help, to cover an area from ground level to as high as required to form a dense cover for a wall or fence.
Without a supply of water plants die as they are unable to keep cool and absorb food. Some shrubs and trees are more susceptible to drought than others and extra care must be taken.
Follow this up with annual mulches of manure, compost or bark when the soil is moist, and you will eventually have an ideal growing medium.
HOW TO ENSURE ADEQUATE WATER
Soil preparation prior to planting is very important, and if plants are to be grown in containers the right potting compost must be used. Soil should be dug as deep as is practical and between 25-50cm is normally ideal. Digging lets in air, as well as water, to prevent root suffocation.
Water-retaining polymer granules can be added to compost or soil prior to planting but be careful to follow the manufacturers recommendations closely.
Adding Organic Materials
Trickle or Soaking Hoses
Trickle or soaking hoses may be used which allow very small amounts of water to be delivered over an extended period of time.
Alternatively a more permanent sprinkler system can be installed.
In the garden 5-8cm diameter pipes or plastic soft drink bottles with the bottoms cut off can be sunk in the soil alongside trees or shrubs, particularly when they are planted as large specimens. These should be topped up with water on a regular basis.
