That was an ingenious experiment. Where did you keep the buckets - inside - outside?
Inside. Our climate has freezing conditions likely thru mid May. This year there was blizzard conditions in May. Many wait until the end of May to plant anything.
We love wild fruit, such as June berries (saskatoons to Canadians), wild plums and wild raspberries. Towards the fall, after the first hard freeze the high bush cranberries are OK to eat as well as the choke cherries sweeten up, ready to eat. The problem up here is a late spring frost will kill the blossoms, and that happened this year. So our fall treats are few and far between.
