Q. Who is Mr. Smarty Plants?

Title: Care for indoor ivy from Carollton TX
Answered by: Barbara Medford

QUESTION:

I have an indoor ivy that is on a pole. The pole is breaking, and I need to separate the ivy from the pole with the least amount of trauma to the plant. How should I do this? Thanks!

ANSWER:

Most indoor plants are non-native to North America. The Lady Bird Johnson Wildflower Center, home of Mr. Smarty Plants, promotes the growth, propagation and protection of plants native not only to North America but to the area in which it is being grown. Apparently, indoor ivies are mostly Hedera helix, native to Europe and and western Asia, and therefore fall out of our frame of reference.

Hedera helix, often referred to as English ivy, is widely grown in North America and is considered extremely invasive if grown outdoors. Apparently, keeping it in a pot indoors makes this consideration irrelevant. From the Guide to Houseplants, we found this article on English Ivy Plant Care. We found no direct reference to avoiding damage when removing a support, but we found lots of recommendations that it be kept pruned, with dead leaves removed, etc. If the plant is doing well where it is presently growing, our recommendation would be to prune back branches of the ivy which are attached to the support, remove the damaged support, and let the ivy re-grow. Just don't plant it outside, it will take over your world.
