Planting Fertilisers & Additives

We offer a range of planting fertilisers and additives, to boost growth and increase survival rates.

Boost growth with Rootgrow

A fast-growing, medium-sized native tree found all over Britain, especially in wet places. Very hardy and coping with a wide range of soil types, Alder is particularly useful for preventing soil erosion, and for establishing plantings in waterlogged areas. Young plants are seldom attacked by rabbits or stock, so makes a good choice where this could be a problem.

Site and soil

Alder tolerates a wide range of soils and situations, except very dry conditions. It will grow well on damp hillsides and in boggy, waterlogged sites.

Height and spread

Below are the approximate stages of growth, assuming sited in suitable conditions for this species;

After 10 years: 8m x 2.5m
After 20 years: 9m x 3.7m

Leaf and bark

The leaves are ovate, and glossy dark green, and deeply lobed, rather like an oak, and about 5cm long. The bark is a greyish dark brown, cracked into thin rectangular plates.

Flower, seed and fruit

Male catkins of Alder can be seen as a purplish haze among the branches as early as January, opening to a dull yellow in March and April. Female catkins are very short (0.5cm), becoming woody 'cones' over winter which are a useful source of food for native birds.

Uses

Coppicing, hedging, specimen tree. Alder wood has the property of withstanding constant wetting and drying out, and for this reason was much used in the past for lock gates, mill wheels and troughs. It has also been used for clog-making and furniture, as well as for smaller items. Both the leaves and the bark were used in dye-making, and the tree has several medicinal uses too.

Wildlife

Alder fruits (false cones) are a useful source of food for birds in spring. The catkins are an early source of pollen and the trees provide shelter on wetland sites.

The main reasons for buying protection is to protect the plants against:

  • Pests
  • Spraying
  • Strimming

Pests

When it comes to deciding what protection to choose the golden rule is to choose the product dependent on which pest you are protecting against. The below will help you in deciding what height of protection you will need.

Spraying

Tubex tree shelters offer the benefit of not only protecting against animal damage, they also ensure that herbicides do not come into contact with the plants during spraying.

The main reason for spraying is weed control, however, there are other options available to suppress weeds, such as weed control matting.

Strimming

Young plants should be protected from damage caused when strimming. To protect plants solely for strimming, our strimmer guards are the ideal product.

Aftercare

Alder hedges should be trimmed in July and August.
