Chester Thornless Blackberry Plant

I have a small orchard & from my experience all fruit needs @ least 1/2 a day of sun minimum. The more sun the better. Direct sun preferred, radiant sun off the side of a house etc... Ok too. Hope this helped.

No. There are, as far as I can tell, no truly seedless blackberries. The Arapahoe blackberry comes the closest, but it has seeds, although they are fairly small.

I use a 12-12-12 early in spring and then after harvest

Yes, just not black raspberries.

Janine;
I grow my Chesters' on a two sided trellis, oriented north to south. Each plant gets abundant sunshine, from 7 am on the east side of the trellis, to about 6 pm on the west side of the trellis.

You have to secure, all of this years growth, to one side of the trellis, in order to make room on the other side of the trellis, for next years' growth.

Check your soil pH is between 6.0 - 6.8. Keep top dressing your plants with compost, and crushed egg shells mixed in. Cover the crown of the plant, 10" wider than the plant, with solid but fluffy large wood chips, shredded leaves, or coarse bark mulch. The concept is, to prevent rapid temperature change, in order to prevent root ball heaving. Prune appropriately, any cane that touches the ground, will root right there, and form a whole new plant. That is why, they are called brambles.

Protect the Crown during the winter, but begin to uncover it, after your last expected snow date is, to allow new growth to begin to emerge. Frost covers work great for new shoots, during the early spring, but unnecessary toward the last expected frost date.

I hope this was helpful

I planted 3 and think they are semi erect the canes are pretty thick. I use two stakes and a single wire for support. I think if you top the primocanes at around 4 feet they would be mostly self supporting. I don't top them though I just bend them back down over the single wire.

Hi Michael. I had the same thing happen to me last year. This year I decided to water them a lot more. I would soak the plants at least every other day, daily if I could. I was rewarded with about 10 quarts of berries and I only have 6 plants. I can't say that is the answer for you but it worked for me. My plants have never looked healthier.

Yes to both. It's hardy and needs space. I have mine on a wire trellis system
and new growth for next year's berries comes from the root.

Not really. Maybe if you work at it. It goes up about 3-4 feet and then without support droops down to the ground, creates roots at that point if you let it and then starts another piece going up. Maybe you can keep it within a circle without support and just keep trimming it. We're only on our 2nd year with these.

I would not recommend to place this plant in a small pot. This plant can spread 5-6 feet. Plus it is semi erect. This means it will lean unless you have something to hold it back. If you have a very large balcony and pot with a lot of sunlight then you can. I have this plant in the ground in my garden and it about 8 feet tall now and only 1 years old. This plants grows fast and are feeders. My growing zone is 7a and these plants are perennials.
