I've planted English Ivy and I'm wondering if I should mulch the area?
If you are using it as a ground cover, I would not use mulch. The little roots along the stems need to be able to grow into the ground. Plus, the groundcover replaces mulch.
If it's being used as a climber on a wall or trellis, yes, I would mulch around it.
d growing on. My 100ft oak has lots of ivy growing all the way to the top. I cut the ivy trunks about two feet from the ground about two months ago in hopes of killing the vines. Nothing is dead. Is the ivy feeding off the tree? I thought about inserting the ivy trunks into a bottle of 50/50 round-up but I'm afraid the round-up may go through the ivy into the tree thus killing the tree. Most of the ivy trunks are at least one inch in diameter.
You could, certainly, try that! Theoretically, your idea is sound.
My English Ivy grows in the shade, and nothing has changed...still in the shade but in the last month or so, and after the scorching month of September, it started to look bad. I was wondering if the extreme heat caused it to start drying up. What can I do to save it
Unless more light has become available to the plant, which could cause scorching, then I would suspect one of two things:
Insects can be an issue. This is especially problematic with really small insects, like spider mites. There are many insects that could be the issue.
Another issue could be fungal issues. You may notice other plants around the area suffering as well, but ivy tends to be, somewhat, disease resistant.
