Here is the result of thornless blackberries cuttings that 'I made last fall.

who can tell me what month I can sow the seeds of this fruit

Thank you.

I'm testing that issue. I'll be putting out my seeds later this month in a flat. I have put them through a mill and I'm allowing them to dry naturally with any remaining material.

I'm hoping to acquire a thornless boysenberry this year as well!

Jack: I would mash them into the potting soil now, and let them do their thing naturally. If you want to start new plants, bury the tips of the canes in the ground, and you will have rooted plants by the end of the growing season. They root here by accident, whenever I don't notice they are touching the ground.

Many thanks Grunt

I am going to try growing blackberries from seed this year too. My neighbors have some thornless plants that produced huge berries this year. They quit picking at 27 gallons, so I picked a few to save seeds from. I will sow them soon and keep them in my unheated greenhouse over the winter. I know some people stratify things in the fridge, but I have good results with just sowing everything in the fall and leaving them unheated over the winter. Simplifies things, and even if things germinate before you want them to, they are protected in the unheated GH. It is amazing just how low temps most stuff can take as long as they are protected from too much winter moisture. Anyway, don't know what these seed grown berries will taste like, but then I don't like them anyway. How bad can it be if you will just be putting sugar in them to make jelly anyway? Maybe I shouldn't ask that...

Karen: If you have enough extra berries, mash up a few and stick them in the ground someplace you will remember. They should come up okay on their own.
