Q.Planting Trees and Killing surrounding weeds
I want to plant three trees (variety not yet decided but will be up to 6 metres tall) but I also want to kill off weeds in this large unused part of the garden. I am hearing that I should do the weed killing between November and March, but I also understand that planting of new trees should be done towards end of the year.
How and when to plant the trees is greatly determined by the varieties you choose.
Here are some links to help you get started.
