Based on this quote by Walter Pall:
"trees don't die of bleeding. This is a bonsai myth. It is possible that after cutting a thick branch or the trunk that liquid comes out of the wound for several days. This is not sap as they say, this is water. This is the water that originally would have gone into the branch or trunk. Now that it is not there anymore it just evaporates or even runs down teh bark. So what?! Nothing lost!!! Eventually the tree will realize that there is an open wound and stop the water supply to a non-esistent part. It is NOT necessary to put something over the wound. if anything tehn vaseline will do. If this were 'sap' it would have to come from above the wound through the cambium. But ther is nothing ther anymore."

And this quote from bonsai4me:
"Acer palmatum bleed heavily if pruned in early Spring. This can be stemmed to a degree if the tree is rootpruned beforehand. I find it preferable to carry out general maintenance pruning and thinning of the branch structure in Autumn after leaf fall.
For the removal of large branches or trunk chops that will cause large wounds, mid to late summer is the best time for these jobs as healing and callus formation is rapid. Avoid making large wounds before midsummer as callus formation can be very poor and result in dieback of the area around the wound."

I have decided that, here in the Fl panhandle, I will cut back a red maple (a. palm.) that I have growing in the ground. Although I will be taking out a few trunks, there will be a lot of branches to be left below it.
What are your experiences with mid- to late-summer pruning with maples?
