Harvest of the Thornless boysenberries is complete. Now it's time to get ready for the 2015 season. Berries develop on the growth from this summer; so the canes that bore fruit in 2014 need to be removed. I removed the bird netting then Farmer MacGregor got into the overgrown thicket and cut those canes to the ground. He also removed any canes with thorns. So much for "thornless". Discarded canes should be burned; but the San Joaquin Valley has very limited times when you can burn. So into the green waste can they go. That leaves canes that started sprouting this year. From those, we select 5 canes on each of the 6 plants to be tied to the supports. Think of fingers on your hand fanning out.
2015 Producing Canes
It's not a perfect science, but it helps to keep this part of the garden tidy. Berries can really get away from you. If you're not careful, your berry patch will look more like a brier patch from Song of the South. Any other canes that sprout are removed. This is something that should be done at least once a week here. We have found something that thrives in this spot of the garden.

As these canes grow, they will be tied to the supports until they reach the top. At that point, they will be pruned to keep at a manageable height. Laterals will form and those will get tied up too. Everything should stay within the support frame. At least, that's the goal. The berries will continue to be fertilized and irrigated throughout the summer. Soil amendment is next on the "to do" list.
