Questions
When should I plant blackberries?
It depends on your zone. Blackberry is a half-hardy crop, so the timing follows your last spring frost. Look up your zone in the table below for exact start, sow, and harvest dates, or open Dibble and set where your garden is to get your own calendar.
How long does it take to grow blackberries?
About 130 days from transplant to the first harvest, with a picking window of roughly 45 days after that.
What grows well with blackberries?
Good companions include Garlic. Keep it away from Raspberry.
