rootmaker and smartpots

Who has used these air/constriction root pruning systems?

If I were to try to grow some trees for eventual planting out in them, I have questions:

1. How do you know when "it's time" to pot up? Do you do it as soon as the root branching has occurred to a point where you can see roots at the outside of the soil ball, or let them "rebranch" a couple times first? Is there a good rule of thumb?

2. Does the "4-inch rule" touted by Carl Whitcomb apply more or less to most plants?

I just posted a thread yesterday on the palms forum and posted a pic of some of my palms I just put up in Air Pots and Smart Pots. I am interested in the answers to your questions as well.

RE: rootmaker and smartpots

1. Couple of rough tests for shifting. Gently try to lift the plant by the stem. If the plant starts to pull loose, it is not ready. If you can lift container and all, it may be ready for a shift. Another sign with some containers is if the plant lifts out of the container but the entire soil ball holds together... Shift. In general, the sooner the shift, the sooner that plant gets a jump on any competition.

2.The "4 inch rule" applies to most plants... A shift once a year does a pretty good job of maintaining that growth momentum. For larger trees, say 3 inch diameter and up, the "inch rule" probably inches to 6 or more inches per shift.

Hope that helps!
