As long as you're only upgrading, the trees will never know (at least not in a negative way). By that I mean no root disturbance.

I upgraded my small meyers two or three times last year while outside. It's only now in a six inch pot (was a tiny cutting from logees).

I was reading here and there on the internet this morning about growing citrus and found something interesting. The article said that trees' roots which are grown in sleeves have a tendency to grow twisted and would get worse as it matured. I didn't make note of the resource because it didn't seem important at the time. I have a few trees that came in sleeves and didn't bare root them when replanting into a different pot. All I did was scratch up the root ball to loosen up the roots. Now I am worried. Anyway, back to the original topic. I thought you always loosen up the roots if you see them around the edges of the rootball. At this point I have not checked any of my trees yet so I am just researching the topic.

That would only be necessary if you held off repotting to the point you have congested, interlocking, circling roots. I have repotted just as the roots are hitting the bottom of the pot (and emerging for first time out drainage hole(s)) and/or you're using a poor soil mix that decays rapidly.

So, I repot early...to avoid root congestion. I'll probably be changing tactics after gallon sized pots.

A tree can be repotted as soon as the roots are capable of holdiing onto its soil when being removed from the container.

My concern is am I going to lose my blossoms and potential fruit by messing with the roots. I am not getting feedback in that area.

If you keep the roots wet, and cause NO damage to the root system, your flowers have a good chance of being undamaged. However, during full bloom is not the best time to repot. A bloom normally last just 2-3 weeks, therefore it is a minimal amount of time to wait.

For what’s worth, had pictures of all the uppotted pictures, all in bloom wi th no loss of flowers, going on two or 3 weeks. I am not telling anyone to do what I did. I did it last. Winter with no problem. I will say this I always try to push the limits for more than I can remember.

I agree that if you work fast and try not to disturb the roots, the tree should not blink and the blooms will hang on. Otherwise, I agree with Silica...why not just wait a few weeks?

I'm ok with waiting. If I wait until the blooming cycle is over, what about the fruit that may be forming afterwards? Will those drop? I found from moving my Meyer lemon in and out and bumping door frames, the fruit falls off easily. I am trying to avoid a repeat of that with all my trees.

I have an ungodly amount of tree,s to take care of, inground tree,s I am talking about. I pace myself and don’t want to wait to the last minute. Citrus is just a small part.

Normally there is always fruit drop after a tree's blooming period. In fact this drop period has been given a name "Early Drop". However as Laura wrote, when done with common care their should not be a problem. With all the experience you have growing citrus, I believe every thing will go smoothly.

I up pot while I acclimate the trees to new solar adjustments. The tree will drop some flowers but most will be dropped anyway.
