Hi, I am wondering if anyone can give me any advise on which tree to buy.We are overlooked in our garden, so to gain some privacy i need to plant two trees.Money is tight so i need something not too expensive that will grow quick !I am looking for a tree that will not bare leaves for first 4 foot so i can still use my border and will not turn out to be so enormous either.pref something green all year round, maybe with a bit of blossom in spring.Not too thick to block all our light either.Does such a tree exist or am i hoping for too much !!!!!
