My four-year old plum ought to have given me some fruit this year. I pruned correctly, leaving plenty of last year's wood, and there were a lot of blossoms. The nativebees were out and I did a bit of pollinating myself. Not one fruit set.
The tree gets adequate water and occasional fertilizer. It appears quite vigorous.
Even though they're self fertile, I think they produce better with a cross pollinator. That may be one issue. Otherwise, the tree is just young. I wouldn't be surprised if it does much better next year. I have a plum tree (different variety) that bloomed a lot when it was young, but produced only 1 plum last year (its 4th). This year, I got about 75 plums. Next year should be great.
Same with mine this year, nothing. It bloomed amazingly but no baby fruits at all. I've read that some fruit trees produce every other year if not thinned because the tree is overworked one year and then takes a break the next. I didn't think we had too many last year but it was a decent crop and I did not thin so it's likely that's the cause. We have lots of other plum trees so it's getting cross pollinated and it was a nice mild winter and spring so no late frosts. I'm inclined to believe the every other year theory for some varieties if not hand thinned. Our old homestead plums produce every year but do their own thinning (we call it the June drop). I do know some of these newer varieties (and by new, I mean last hundred years or so) don't self thin well enough or at all. I read that was the case with apples, specifically Fuji, really needing hand thinning. This was from Michael Phillips,
who I believe to be very knowledgeable on the subject.
I'd be willing to bet we need to thin our Santa Rosas.
I have a 20 year old Santa Rosa...it is my favorite plum. I do have a cross pollinator. I find that here it is not reallyreliable as a producer. Some years nothing..this has been a wet, wet spring in Eastern Washington and it’s loaded.
I don’t think what you are experiencing is unusual. It really didn’t start producing for me until after the 4 th or 5 th year and then some years not so much.
