Good morning and merry 2018 spring (whenever it happens in UK...)!
I wonder if you could have a hunch of what I should do with my blackberry bush.
It is not in the sunniest of sites, but it gets some afternoon sun. It has bloomed moderately this summer, but the calyces just stay there once the petals drop, and in the (very) long run simply rot. I've sprayed the plant with fungicide and acaricide, and it looks OK (for my garden standards). It was bought without label or whatever.
Do you think it is not self-fertile? If so, will just another bramble do or how many should I have? My cuttings from these plant have rooted, but I guess this cheating won't do, will it?
Glad if you can think of something!
