First ripe blackberry: June 27.
This plant has grown really well without a lot of attention. Growing blackberries in Utah is easy.
My mom grew up in the pacific northwest and we have been up there many times. We are always amazed that blackberries are, for the most part, considered weeds and many of the berries just go to waste. Last summer we were given a small start by a friend. We planted it in the southwest corner of the yard, next to a fence and the garage. It grew a bit and the snow came. This spring we found out why it's a weed. It went crazy, producing a ton of vines and growing about ten feet tall. A couple of weeks ago I chopped it back, being careful to avoid vines with fruit and vines in general (they have big thorns). It looks like we are going to get a large crop of berries, and the plant is relatively contained in a raised bed, so we don't mind its aggressive behavior for now.
Blackberries turn dark before they are completely ripe and don't ripen off the vine, so be patient and wait until the berry comes off with a gentle pull. Also, it's best to pick the berries in the early morning. They become soft and more prone to bruising in the heat of the day.
