Trees should only be bought from a recognised forest nursery and should be ordered well in advance of planting. The trees should have a strong fibrous root system, a straight stem and meet the size specifications as described in the afforestation grant approval.
Good plant handling is as important as plant quality. The bags of trees should be handled carefully and ideally the trees should be planted immediately. If stored, the bags should be kept upright in a shaded place or shed and planted as soon as possible.
Trees must be planted with care to provide the best conditions for successful establishment. The principles of good planting are:
- Ensure the tree is planted upright
- Plant tree to correct depth (i.e. root collar)
- Carefully place roots into the soil by hand
- Cover all roots with soil and firm in well
The planting season normally runs from November to March when trees are dormant and can be safely planted as bare-rooted trees. The planting season can be extended by using plants from cold storage.
