There is less bite in autumn wiring because there is very little wood movement at all until spring and since no sap is flowing there is less outward pressure, maybe even a sigh. Add to that lignifying for ~5 or 6 months, and you get good effects on woody plants. Maybe not as good as fixing the shape while actively growing, but there are always trade-offs.
Graham makes great videos, I don't know why he stoped other than there seems to be questions about his use of some of the music applied to his vids and I assume copy right issues.
that, and time. For a while he was flat-out just keeping up with orders and stock.
How deep into fall?
I wish he would mic himself a little better though and the reflection off of the background plastic made him look like some kind of illuminated gnome!
Yes, I've (so slowly) come to understand that. I will offer to you that in our tended pot culture it is not much, if any, effect. I've overdone root work in repotting that took an entire season for the trees to recover from. However, my instinct is that the roots recover in a couple of weeks of a properly done repot. I measured stem thicknesses of at least 8 trees of several species through the season. Week by week stem thicken more and more as spring progresses. Then shortly after the summer solstice this rate declines, week by week until cold dormancy sets in. Half of each species of tree was repotted in Aug/Sep and there was no significant disruption of the growth curve from the other trees that were repotted in spring. My repotting routine was to wash all the substrate out of the roots (done to weigh the young trees), invert the plastic nursery pots they were in, pruning the roots to the perimeter of the pot base, and then repotting the tree. The amount of root pruning is roughly equivalent to what I think to be normal practice with bonsai.
Till about Sept 14 if there has been no frost. I have gone into the first of October but that't risky.
No, what I am saying is.. Make up your mind, and decide what you want to risk. I have found trees to respond very well to rootwork at this time, provided aftercare is proper. But then again, I think this is more than enough roots when layering..
What is your average temp there. Throw out the high and the low for a week and whats in between? For me it's about 99/100. This week is a cool down and the average will be 97, then back to the hundreds next week.
Hey Vance I just have a question about fall repotting maples. If you had to drastically root prune and bare root a trident. Would you still do it in August or wait till spring? I think this is the main problem people have with late summer repotting. It seems that others are saying to not do major root work. Seems that you can repot anytime if you only slightly reduce the roots.
I think the vitriol promotes intelligent and useful information. It gets people to speak up with information that is both the positive and negative aspects of the topic at hand. Even someone telling about how something killed their tree swearing they will never do it again doesn’t stop me from doing it, it just makes me aware of a potential caveat. It also gives me a better feel for the people who are involved in the conversation, for better or worse.
