First of all hello to everybody, this looks like a great forum. Let me introduce myself...

My name is Brian. I had zero horticulture experience until this spring. I just bought a house in the winter and that was previously owned by a landscaper and is filled with a huge variety of plants and trees that obviously had not been maintained for a few years. There was a raised bed that was probably an herb garden that was overgrown with weeds. I decided to till it and plant a vegetable garden.

Being impatient, while waiting for seeds to sprout I went out and bought a whole assortment of fruit trees and berry bushes, including four potted citrus trees. I repotted the citrus into a mix of potting soil, sand, hardwood mulch, and perlite. I forget the ratio, it was roughly equal parts. I found the recipe after a google search of citrus potting medium.

One thing I noticed was that the Washington Navel orange had circling roots, about one full revolution. I didn't cut them because I wasn't very confident at the time, but I want to fix it before the tree chokes. The thing is, it just bloomed and had a huge growth flush. I read on another thread not to interrupt it when it is blooming, but how long should I wait? There are still a few blooms left but mostly the flowers have fallen off, leaving swollen pistils I hope will become oranges.

Should I take it it out and cut the roots now, or wait a little longer? If so, should I cut off some of the old leaves to match? Should I put it in a bigger pot also?

Welcome to the forum, thank you for becoming a member. Since you have already re-potted the tree into what sounds like a good draining soil, but you did not say how long it has been in the new container, I would just let it be. The tree will not "choke". As it has produce a new flush, the tree must be doing fine. - Millet

I repotted it when I bought it about two months ago. How long do you think it would take before the circling roots become a problem?

I was planning on waiting until next spring to repot them all into slightly bigger pots, but I wonder if the orange tree might already be too big for its current pot. It is clearly older than the others.

It all depends on how much larger the container was that you used when you re-potted the trees. Generally, a tree needs re-potting once a year. Waiting until springs should be fine. When you do re-pot the trees, if you use an Air Root Pruning Container from the Root Maker Co. you will never get circling roots again. - Millet

millet,

What is the situation with the Rootmaker products and watering. They state on their website that the product retains a greater amount of water than traditional pots. Is that ever an issue with citrus in decreasing available oxygen to the roots? How does the frequency of watering decrease on the average compare to a normal pot? Thanks.

Almost all of my citrus trees (100+) are in Air Root Pruning containers (ARPC). I was not aware that their web site said anything about water retention. I have never noticed any excess retention. In fact if you read my thread entitled "Experiment/Verification" concerning every day watering, the experiment is being carried out in ARPC. Currently, I have citrus trees all sizes of ARPC 1-gal., 3-gal., 5-gal., 7-gal. and 25-gallon. - Millet
