In July I tried a series of black and red pine for suspected root aphids (see “Why my yellow trees”). I’ve noticed some changes since then and wanted to share what I’ve seen.
My biggest concern when drenching the two pines three years old was that treatments could damage the roots. Although it is too early to say, I can report that there has been no evidence to suggest catastrophic changes to the trees that were treated. On a more positive note, I have noticed some trees turn yellow to green. New pine needles on the bottom were yellow before treatment. Although yellowish needles remain old, new needles have budded considerably.

who have no way of knowing whether or not the greening the result of any treatment, but I am happy, however, because it is a sign of the health of the tree.
Some of the healthiest trees now send out summer sessions.

often think of black and red pine trees and sending new growth once a year – two when decandle – but healthy pines summer regularly send shoots when they are growing vigorously. This is particularly true of young pines.

Pulling a random floor, I noticed that all but one of the trees had summer outbreaks.

These trees will all need wiring and transplantation before next spring. Meanwhile, I will continue to feed largely to help the trees to prepare for winter.
