Hello! I am a newly retired school teacher with a BIG yard and lots of trees. I've been trying to get the yard under control and I made a mistake. Question #1 - I didn't know I shouldn't prune my holly till winter. Should I protect the limb cuts with a sealant? Question #2 - Second mistake, I allowed English Ivy to establish a home in my yard. Now I'm fighting it. It's like the evil empire. I'm pulling it out by hand in the humid heat of NJ August. I don't want to kill any of the other plants it has infested. Any suggestions? Thanks to any pros out there who have the time and generosity to offer aid to a novice. By the way, I was the nice teacher, not the mean one!
