Planting a tree.
I have bought three six foot Cupressus m Goldcrest in pots about 15 inches across and I want to be certain that I give them a good start so would anyone care to set out what I neet to do and if I .
By that I mean should the hole be proportionately wider and if so by how much?
Should stake them?
Do I need to put any fertiliser in with them?
How often do they need watering?
I just want to make sure that I cover all there needs.
