We had problems with our Currants being too near White Pine. They share a disease that effects the currant leaves; Pine Blister Rust. Ouch!
We moved them along our driveway and the wildlife is liking them. I harvest what I can. ;)
My plum (Mount Royal; self-pollinator) were FABULOUS last year, and plentiful.
I am on my third replacement cherry tree (North Star) so it can cross with the other one I already have. Same with the peach, but this will be the second replacement. (Contender)
Puppies chewed on the cherry before I noticed, and the steer (who escaped one day) used the peach as a back-scratcher and broke it.
THIS is why we can’t have nice things, LOL!
I think I read one time that they like to have their roots shaded by other bushes. Anyway, I've got most of my currants nestled in the same corner of the garden where my main yellow raspberry patch is located. In that spot they definitely outproduce the currants growing in another spot on their own. I freeze a few quarts of the currants every year, but I probably only pick half of what is there before I have as much as I'll use.
At this point, I'm doubtful that I'll get through all my frozen plums and cherries before its time to harvest again. Its just me living here though, so I'm having to eat them on my own. Besides what the birds get and what I give away, of course.
