i know summer is also a good time to repot but i thought late winter/ early spring the optimum time, no?
I'm working on finding the actual latitude that separates spring from summer repotting success, I believe it exists with a "coastal caveat". Any microclimate really.
While learning about onions, (long day, short day) I realized we get about 3 more hours of sunlight then some folks down yonder midsummer.
I reckon this extra 1.5 hrs of sun in the cooler morning and evening is what allows for a much faster recovery up here if repotted in summer.
3 hours of more sun moves plants into an entirely new category eh, "part shade" is 3-4 hours full sun, "full sun" is printed as at least 6 hours. It's like a whole new health tax bracket for trees!
Our, at least my, trees come out of dormancy from the top down.
To me this means as soon as there is life atop, cross talk begins, except when we disturb the roots, we essentially take that phone off the line so the first call down to the roots is a busy signal, so the top keeps growing. Then by the time the roots pick up, they have a bad message, "we've been changed".
So the top tells the bottom to grow more, and the bottom is like, nah bruh, too cold, you're going to have to ditch some foilage, we can't support it.
Hence the death.
Sap, messages, are flowing much faster in summer, so even if we create an imbalance by repotting harshly, the tree can communicate it faster.
I believe the information communicated between tops and bottoms is way more complex than we think, like, the roots know everything about a branch, Everything, size, length, leaf number, turns, nodes, damage, age, direction, time each inch is shaded....etc ... everything.
We should consider cross talk this importantly.
