Boysenberry Plant

When do I trim back my boysenberry limbs? They never produced as yet, and they are over 6 ft. long with no berries. What do I do?

Also, is it true to cut a lot of greens off my tomatoes and they might produce? They are very tall and healthy looking but do not grow tomatoes.

Yes, I would cut them back some. This article on thornless blackberry pruning is the same as you would treat boysenberries: http://www.wvu.edu/~agexten/hortcult/fruits/prunblkbr.htm

As for the tomatoes, pruning isn't always recommended. If you are having difficulties with fruiting, it could be any number of things, especially if you see lots of foliage growth. This could signal too much nitrogen in the soil. Adding phosphorus, like bone meal, can oftentimes correct this. It could also be weather related.

The boysenberry plants grew very long branches, with beautiful leaves, maybe 6 ft. long. They did not grow any berries. Now all the leaves fell off. Do I cut them down to a certain amount or do I leave them alone? They are about 8 or 9 months old. What to do with them? All my fruit leaves have fallen off, do I prune them now or when?

My boysenberry plants are over 6 ft. long, have not produced as yet, but all leaves have fallen off. Do I cut them back or what do I do? Are they dead? I need to know.

Second question: Do I cut my asparagus ferns back now? They are only 1 year old.

They had ony flower this summer, id didn’t produce any fruit. This was second summer in garden. do they fruit on second year stems. They are in same area as blueberries, and planted borage for first time. would that affect flowering. Borage grew big. The first year had a few fruit on boysenberries.Thanks From Janene in Christchurch.

When did you plant your berry plants?

It will take 2 to 3 years for berries to form on Boysenberry plants.
