Poison Ivy Control

Alan in Catskill writes:
We moved on to a property with extensive poison ivy. I tried a little Roundup, but was concerned about doing in the flowers and shrubs. Aside from a few dead leaves, no effect seen. I pulled up a lot of plants with long runners, but plenty left. Family members extremely allergic.What do you recommend? Thanks.
Controlling poison ivy is difficult but not impossible. If you can mow the area be sure to do that often. If not, pulling it up is a very effective means of controlling it, but be sure to wear protective clothing. The best time of year to pull the ivy is in winter when the plant has no leaves.
A concoction that a listener suggested a couple years ago (and one that many listeners have tried with success) is a mixture of one gallon ordinary white vinegar, one pound of table salt and 1 teaspoon of dish washing liquid. Spray this on the poison ivy leaves and vines. Be sure not to spray the surrounding plants. Be prepared to spray this repeatedly until the plant dies. Even with chemical sprays you have to spray more than once to kill this annoying vine.
