Dear DIG IT!
Our son gave us a Dogwood Tree which we have planted in the front yard. It has been doing very well, with a lot of new growth this summer. This past week I noticed a type of white web on one branch and the leaves are all dying. Should I just cut off that branch, or should the tree be sprayed, and if so, with what?

Ruth

Dear Ruth,

It's possible the tree has fall webworm. If it does, worms will come out of the webbing and feed on the rest of the tree. They tend to stay near the nest, so look to see if there is any worm activity in and around the web. If you see worms, spray with Orthene, Sevin or Malathion.

If you don't see any worms and the branch is small, you can cut it off.

Thank you,

Dear DIG IT!
I Live in central NJ where the deer out number people, or so it seems. I love the deer and the wildlife but, I also love the look of Ivy and have successfully created an ivy topiary in my previous home, deer and all. For some reason every Ivy I seem to plant gets eaten up immediately. I spray a few of my other plants which the deer and I are fond of but, I was hoping I could find an ivy or other evergreen vine that I would not have to spray and the deer would find it non-edible. Any ideas?
Thanks,
Linda Leach

Dear Linda,

Off hand I don't know of any vines that are deer resistant, except maybe Wisteria and Clematis. I would continue to use deer repellant on your vines (you should only have to spray 8/10 feet high on the vines) on a regular basis. If you don't like the smell of the repellant you are using try using one of the mint based repellants such as Deer Stopper or Deer Away.

Dear DIG IT!
I live in coastal Wilmington, North Carolina right on the edge of Zone 7
and Zone 8. Wisteria grows wild everywhere here so I dug up a large
shrub-type bush of Wisteria and transplanted it in my yard last week
(late April). I put it in my regular soil (no fancy top soil or
fertilizer) and have been watering it once a day.

After one week it looks very wilted and droopy. Should I stop watering
it? Should I prune the wilted blooms and leaves? Should I prune the long
runners or laterals? If so, should I do the pruning now or wait until
later in the year? Thank you, Linda


Dear Linda,

The first thing to do if you haven't done it alrteady is to whack off at least one-third of the plant to compensate for root loss. If the plant is large as you mentioned, maybe remove even more - half. The blooms and long runners will come off with this heavy pruning. I wouldn't worry about the rest of the wilted leaves - if they want to fall off, they will.

Then, keep it well-watered but not soggy. This super-sturdy plant still needs to be protected from hot sun while in this delicate transition. Shield it from mid-to-late afternoon sun by placing a burlap barrier around the southwestern side of the plant, high enough so the created shade extends over the top of the plant.

Once established, look out! You'll need to clip off the long runners again in summertime. Good luck to you! And thanks for "Asking DIG IT!"
