In my tiny front garden have a 200 year old oak tree (TPO!) which has produced a bumper crop of acorns buried by a squirrel. So, now I have a forest of oak seedlings and if anyone would like a few to plant on their land send me a pm with your name and address and I will send you some. No charge for seedlings and donate p and p to your favourite charity.
with love, Sylvia. X
