Just planted 2 pluots (Flavor King and Flavor Supreme on citation) in the air pruning container 35L (9 gallon). They sent me 2 years old big trees, I had to butchered the root to fit the container. Please see attached photo. The container mix I used is miracle-gro potting mix. I am in zone 7b (SE NY). I do plan to bring the containers to unheated attached garage during frost months. Am I doing it right?
I’d suggest a bigger container if using that type. That’s going to need watering twice a day.
Also the tree looks to be too deep in the pot. Those roots should be just below the soil surface. The roots will grow down better than up. In that pot I’d want it as full of media as possible with the upper roots just below the soil surface. That may mean staking until it gets rooted in.
Thank you all for the reply. I also removed most of branches on the top. Headed back about 24 inches above graft union. Do you think I can wait until next year to repot?
See how the watering goes and how the tree grows. That will tell you when and if to up pot. You can stick with that at least one yr, maybe 3-4 yrs. The pot looks bigger here than above.
I’ve found the tree nearly stops growing after about 3-4 yrs in a 12 gal normal pot without the holes on sides. At that point the tree needs repotting or up potting, and renewal pruning.
I’ve fruited apricots in 3-4 gal pots. Same for three trees in a 12 gallon pot. So if you can rewet the media in those pots without too many issues you can get fruit. If the media gets too dry it can be hard to rewet. At that point I stand them in a shallow saucer to help rewetting.
