dr. frankenstein’s plum tree
While John and I were out looking for a small ornamental tree at our favorite local place to shop for plants, Walter Anderson Nursery, we passed by some bins of bare root fruit trees. We weren’t in the market for a fruit tree, and we really don’t have the perfect place to put one.
But John eyed the bins wistfully. “I’ve always wanted a plum tree.”
Our past experience with a stone fruit was a variety of apricot that was supposed to do okay without much chilling here in coastal San Diego. It’s been almost a dozen years, and that’s probably how many fruit we’ve harvested off the tree. Some of the fruits were eaten by critters before we got to them, but for the most part the issue is that there just haven’t been many fruit to begin with. It just doesn’t get cold enough here for success with apricots.
I had that discussion with Kurt at the nursery, and he assured us that all the plums they carried were selected to do well in this area. I wasn’t totally convinced, but with John and Kurt working their influence, I gave in. We now have a plum tree. Or is it five plum trees?
We walked away with one of those Frankenstein multi-grafted plants, with a branch of five different varieties. The theory is that they’re selected to provide a long season of fruits. But the reality of multi-grafts is that the vigor of the different varieties is never the same as that of the others, and one or two varieties often take over unless you continue to prune the plant carefully. In fact, one of the varieties is listed as being particularly vigorous. Uh oh.
John like the idea of the long season. I liked the idea that out of the five varieties we might actually find one that does well here–and actually taste good. If a variety doesn’t bear after its trial period, off the island it goes. Here’s what we ended up with:
- Santa Rosa: 300–400 hours chill requirement(below 45 degrees) . This variety is the one that ends up planted everywhere in Southern California, and it seems to set fruit pretty reliably. The flavor isn’t anything to get excited over, though. It’s in the “why bother” category for me, and I’ll be really disappointed if it’s the only one that does anything.
- Burgundy: 300–400 hours chill requirement
- Golden Nectar: 400–500 hours chill requirement
- Beauty: 250 hours
- Methley: 250 hours
Now, less than two weeks in the ground, some of the branches are blooming already. Encouraging. But I suspect the tree was at least somewhat pre-chilled at the originating nursery.
Interestingly, the branch with the most green foliage and no flowers at all is the supposedly low-chill Methley. And the other low chill variety, Beauty, has next to no flowers.
I’ll report back on how this all goes. How I love a good experiment!
