My trees are 2-5 years old. They got little pruning these past few years because I was not sure how to go about it correctly. I've tried to learn how to prune from reading several posts here. I also like watching selected YouTube sites since I am a visual learner. It's quite intimidating. I often think that the trees they pruned on Youtube did not look anywhere like my trees. That makes it harder for me to get it right.
Today I watched on guy using tree sealer to seal all the cut wounds of the tree he pruned. I did not hear much in this forum about the use of tree sealer.
Is it really helpful to help prevent diseases from entering a tree from those wounds? If so, what brand would you recommend? If you don't use sealer, what do you do you do? Do you seal cut wounds at all. Some of the branches I pruned off (today,before I saw this guy on Youtube)were almost an inch in diameter. Thank you.
