What to Grow

Most forestry trees are easy to grow and require very little maintenance.  The choice of trees is vast so a good starting point is for you to consider what you would like the forest to supply.  Our catalogue is full of suggestions to help you decide under the notes on particular trees. To help you, we give below a list of trees suitable for different uses:
Practical uses

Planning your Forest

Here are some answers to the most frequently asked questions:
What is a suitable site?
Almost all sites are suitable for some form of woodland trees, no matter how hostile the conditions.  Forestry trees primarily grown for timber are easier to manage when planted in blocks of ½ hectare or more, but it is possible of course to have small woodland of 20 trees or so in an unused part of the garden.  Forestry trees are ultimately much easier to maintain than wastelands.
How many trees do I need?
For tall upright trees at 2m spacing you will need approximately 1100 per ½ hectare
For wider growing, multipurpose trees at 3m spacing you will need approximately 550 per ½ hectare
For informal woodland with trees at 4m spacing you will need approximately 300 per ½ hectare
What do I need?
The trees, canes, cones, strong small spade
When should I plant?
Any time when the trees are dormant (between November and March)

How to Plant

Once you have chosen your trees and site, the easiest way to start is to line out sturdy bamboo canes in the positions you would like to see the trees.  These can be as close as 2 metres apart if you would like to see an upright true forest, or spaced to 3 or even 4 metres if your intention is to create an aesthetic woodland.  Once the canes have been firmly pushed into position, it is now possible to plant.
If you are planting several different species together, take a few of each tree and place these in a separate plastic bag (it is vital that the roots stay damp before planting, as left out in a cold wind, trees will very quickly die).  Try to plant randomly without thinking about the mix of trees.
Firstly make a T cut in the soil using a small sharp spade.  Make a horizontal incision in front of the cane on the side opposite the prevailing wind (normally East side as the predominant winds are from the west).  Next make a vertical cut away from the cane to form the T.  Once the spade is in the ground waggle it from side to side to produce a slightly opened T in the soil.  The depth of soil you will need to cut through will vary according to the variety of tree and the supplied height, but should be about 20 – 30cms deep.
Tuck the roots of the tree into the hole as deep as the planting mark before making sure there are no roots left exposed.  Now close the T by heeling in the soil either side of the tree, making sure there are no large air gaps, and take care not to damage the tree.
If the site is particularly weedy, it is possible to weed kill in advance or simply clean the weeds with your boot just below the cane.
Once all of your trees are planted, you will need to place a short rigid cone over the tree and attach it to the bamboo cane.  This will do many things:
  1. Keep the tree protected from wildlife.
  2. Supply a micro climate for the young tree, keeping the tree warmer and wind free in the winter months, but cooler in the summer months.
  3. Allow easy maintenance for weed killing and or strimming.
  4. Help the tree grow straight and upright, encouraging the development of a leader.
  5. Protects your tree from machinery.
That’s it.  It’s as simple as that and takes just a few minutes to plant each tree.
 

Maintaining your Forest or Woodland

For the first few years, it will be necessary to cut or weed kill the undergrowth around your trees.  It is common practice to cut between the rows of trees with machinery, but weed kill around the base of the trees, around the cone, normally for about 1m2.
It might be necessary to lift the cones slightly once a year and remove any weeds growing from inside the cones, however most trees will overcome the weeds themselves.
It is not normally necessary to feed or compost young, mostly indigenous trees.  After a few years the cones will start to break down naturally, when they can be collected up or left to biodegrade.  In subsequent years, just ensure the lowest branches are removed (if you particularly require a forest) for easier maintenance at the base.
