plum pollinators

I can't find anything that shows a single good pollinator for both.

Honestly, I wouldn't bother planting another tree for pollination, unless you want more plums anyway. If you do, an allrounder like santa rosa or wickson would be a good bet.

You could also graft a small piece of one of those varieties to your existing tree pretty easily.

- most plums are at least partially self fertile, though they benefit from cross pollination
- they seem to cross pollinate pretty readily, so long as the flowering times coincide
- if you are in a suburban area there is a 99% chance there will be a dozen compatible plum trees within bee range, and probably a lot more.

I have 30 odd varieties of plum. Some set fruit the first time they flowered, some didn't set anything for 3 or 4 seasons, so don't panic if it takes a little while :)
