I can only let my citrus trees get so big since I have to bring them inside and up a stairway for the winter. 10 gallon is the largest container I use. I prune them to keep them to a manageable size.

Ken check out Magliner. You can build your dream handcart for moving citrus. Wide tires, stairclimber runners, curved back for pots, magnesium nose, long frame, vertical loop, 10" tires, microcellular wheels. It's a sweet ride for citrus. https://www.magliner.com/product/design-your-own-handtrucks/design-your-own-handtruck

Nice tree Steve. What's the height on it?

Ken, I hear you, I think my biggest limiting factor is going to be weight as I need to be able to move them outside to repot and my biggest tree is already pretty heavy. I am looking into some plant dollys though to make it easier to move them around at least in their own room, so that gives me a little wiggle room.

Ken, when you cut your trees back do you cut the roots eventually too?

I have not root pruned yet but t it's getting towards that time on my lime tree so I think next spring will be my first attempt. I don't plan on putting it into a bigger pot and it has been in it's current pot for 3 summers now.

I also have to move mine indoors during winter so I keep them under 6'. I have a appliance hand truck to move them. It has a strap and a roller for stairs which makes it easier.

I've never root pruned them, I know I should but I'm not sure how to and think I would kill them.

Root pruning isn't too bad once you get the hang of it. It's helpful to practice on faster growing, cheap plants to get the hang of what you can remove/how much to remove.

I have my old Meyer Lemon in a pot that is about 30" x 30"; I have no idea how many gallons that is. It's been in that pot, un-root-pruned for over 8 years. The Bay Laural ( that wants to be a tree ) is in the same size pot, never root pruned, but heavily branch pruned to keep it a shrub.

I also am afraid that I'd kill the old dears if I tried to root-prune them. That is IF I could even manage to wrangle the weight and size in my old age.

i go hard on root pruning my trees, never killed one yet. ill take a good 1/3 of the roots at least. i completely slice off the bottom few inches with a hacksaw, and cut 3 wedges from the sides of the rootball. just leave them in the shade for a few weeks and it should be ready to grow again.

I use 1/2 wine barrels for my trees. I have 18/22 in containers and a few avocado trees in the same size containers and 4 stonefruit in similar size containers.

Nick Could I see some pictures of your stone fruit trees.

steve I accidently posted it in the most productive tree thread

How do your stonefruit do Nick? We are in similar climates and I am interested in trying my hand with some.

Nick Some of the most productive endeavors come from accidents.

Nick, how do your stonefruit trees do potted? (They look awesome).

Indeed they do steve and they have been producing well the past 2 years.

Kate, very easy to root prune and no lifting involved. Use a shop vac and remove potting soil around the circumference of pot.
