Blackberry with NO new canes?
Hello, folks --
I saw the thread for blackberry with FEW new canes, but thought this might be a different problem...
My favorite blackberry (unfortunately a well-meaning friend threw away the tags -- I have learned my lesson and now make planting maps, but this berry I do not have a name for) has, this year, one cane about 15 feet long, with lots of fruit. But, so far, no new canes for next year! Is there anything I can do to encourage it?
It has a ton of root space and compost. It had, last year, been crowded and shaded out by other plants, so this year I put it in a large (20-inch) pot in a sunny, airy location. I have other blackberries in smaller pots/bigger plants, and they are happy. And this plant seems very happy in terms of top growth and fruits, just no new canes.
It has a chipped-wood mulch. I don't THINK it is deep enough to prevent sprouting, but I tried pulling the mulch back, about 6 weeks ago. Still no sprouts. Should I remove it completely?
I know they are tough plants and if I leave it alone it will probably survive and make canes next year, but that means skipping a year of fruit. Alternative suggestions would be welcome :).
