collecting tree seeds

Mostly October, maybe into November, depends on when we get first frosts.

Watch out with stands of beech as they only produce a good crop of mast every few years. Sycamore and Ash probably have seedlings about 4-6 inches high nearby so if you keep an eye out for them now, mark them and transplant them into pots etc. when they go dormant. Won't guarantee what tree they came from, but you'd be a year ahead.
