Thanks.Yeah, we get a lot of rain, mostly in winter and spring. We average about 36in per year here. Summers can be wet, too, but last year was an unusually dry one for us. That meant a bigger and longer tomato crop, since the plants usually get disease ridden by August.
Anyway, we have three trees on G30, they all have flourished, no matter where they’ve been planted. I wish more of my trees were on it. When I bought my trees years ago, I was more focused on the variety instead of he rootstock, so I may be paying the price for that now.
I can’t move some of my bigger trees, but there are 3 or 4 that I’m considering moving because of water issues. They have struggled to get established, excessive water may be a culprit, but it also could be the rootstocks and or the soil quality.
Regarding Goldrush, I have a potted one I grafted on M7 a couple years ago, and five other varieties, so those are going in the ground in a couple of months. I have other M7 trees, and they seem to be a slow grower the first couple years, but last year has really took off. They seem to tolerate wet feet okay. They do produce rootstock suckers, though.
