I have two thornless trailing vine blackberry bushes. One of them produced lots of berries while the other produced none. In the early summer after the one bush was finished producing I didn't know I was supposed to cut off the canes that had fruit on them. The vines grew very long over the summer despite the fact that I had a mold problem because of excess rain. There is only one main cane coming out of the ground so I'm not sure how to prune it. What branches do I cut or is it too late?

Hello, Long story short, winter is coming (we have a frost advisory here tonight in central Indiana) and I have this blackberry plant seedling growing in my backyard. It has maybe 5 leaves but is barely an inch tall. What can I do to save it? Will it survive the winter or should I dig it up and plant it in a pot for the winter (bringing it indoors, of course)?
If you are ever in doubt, dig it up and bring it in. Just make sure to dig wide to salvage as many roots as possible. You will want to plant outside in spring the first chance you get. These won't survive more than a year or so in container.

My 4 year old Triple Crown blackberry has morphed into these odd ribbon like canes. Others are amazed and we are enjoying watching progress but, could this be a bad thing?

We planted blackberries three years ago and have yet to see any fruit, It appears that they are going to produce with little green fruit but it never goes past that, All we get is higher and higher canes with leaves but little to no fruit. Should we give up after three years and take them out of where we have them planted or can they recover somehow?
Are there any other symptoms that you can see? It could be that the soil is lacking fertilizer.
Alternatively if the growth that is on it is a real dark, and lush green, but no fruit then this could be a sign that there is too much nitrogen in the soil. This can be fixed by adding phosphorus and potassium to the soil, or simply raising the pH just a little with some dolomitic lime.

The bushes are about 6-9 feet. it does look like they are starting to bud. We did get them pruned earlier, what should we do now?
The answer really depends upon when you had the plants pruned before. Blackberries should be pruned twice per year - once in the summer after fruiting to remove all the old canes, and once in the spring to trim the tips and encourage branching growth. If you've already trimmed the tips this spring, then there's nothing else you need to do. (Although you could cut them down to a more manageable 6 feet or so. You'll miss out on the fruit from the tops of the canes, but they'll be a whole lot easier to harvest).

I have three thornless blackberry bushes and there are no blossoms at all on any one of them. The foliage looks good, however and I have followed all of the suggestions for blackberry care, such as pruning, trellising and fertilizer. Jaykay
If you are pruning properly, the lack of blossoms could be an issue with fertilizer or with the age of the plants. It's possible that your soil already has sufficient nitrogen, and that added nitrogen is suppressing flowering. You could try adding a phosphorus fertilizer that doesn't include nitrogen.
