Planting Fertilisers & Additives

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

Boost growth with Rootgrow

Native to Europe and the Caucasus, the Grey Alder was introduced to Britain around 200 years ago. A fast growing deciduous tree, it does well even on very dry soils, is often used to reclaim derelict land and spoil heaps, and in the wild it can be found in habitats as diverse as rocky mountain slopes and boggy riversides. The smooth, dark grey bark makes it an attractive choice for planting.

Site and soil

Although tolerant of a wide range of soils, the Grey Alder is especially good on dry, infertile soils where little else will grow. It does, however, need good light to do well.

Height and spread

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

After 10 years: 9m x 6m
After 20 years: 20m x 10m

Leaf and bark

The leaves are ovate and sharply pointed, dark green and shiny, grey beneath and densely hairy. The bark is a distinctive smooth dark grey.

Flower, seed and fruit

Clusters of 3 or 4 yellow-brown catkins appear in late February, developing into hard green fruits in summer. The woody ‘cones’ remain on the tree over winter.

Uses

Alder makes an attractive specimen tree and can be used for windbreaks, hedging and screening. It plays an important role in the reclamation of derelict land.

Wildlife

The catkins of Grey Alder are an early source of pollen for insects, and the ‘cones’ provide food for birds in winter. Its ability to grow well on the poorest of soils – even on spoil heaps – where the nitrogen-fixing nodules on its roots improve the fertility of the soil, makes it invaluable for reclaiming derelict land.

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

Grey Alder hedges should be trimmed in July and August.
