Introduction to arboriculture

Trees can be beautiful, spiritual and essential , but in a garden to some people they can be a nightmare. You can turn your nightmare into a dream by the simple task of knowing your tree. so i have collected some links for you to explore, where you will find the best methods to keep your nightmares away.
You need to know
  1. what is the tree species (essential to discover more knowledge)
  2. how big can it grow (make sure if planting, that it will not outgrow it's position,)
  3. is it native or not (native trees will require little looking after, foreign trees can need to be kept free of competition)
  4. what is its natural environment (i.e monkey trees grow well in sandy/free draining soil but poorly in moist or clay soils,english oak likes moist/clay soils but does poorly in free draining soils,sessile oak does ok in thin soils)
  5. can it be pruned (cut all the foliage off a conifer it dies, cut all the foliage of a young decideous tree and it should resprout ,although if you cut all the foliage/buds of a mature tree it can die,particuly oak and beech)
  6. what is its root pattern (willow roots grow wide and shallow, oak grows deep and not so wide,cherry trees can do both)
  7. about the tree (i.e what are its flowers like,what colour are its leafs in spring/summer/autum does it fruit or is it sterile or a male tree,will it's flowers have a fragrance)
  8. what type of fruit does it produce (small berries for little birds, cherries for big birds/yourself , nut trees for you and the squirrels,or pretty ones like the spindle tree)
