“Buggy” Oleanders

Q: Howdy, we live in Dallas and we are having some problems with bugs on our oleanders. Tiny yellow/black insects and most recently some very tiny worm looking things. Any suggestions regarding treatment?

A: You may have the start of an infestation of oleander caterpillars, which are the most serious pest of oleander. These caterpillars eventually become orange with black tufts of hair and they feed in great numbers. Treating them while they’re small is key to their control. Try spraying the foliage according to label directions with a biological control called Bacillus thuringiensis or B.t. for short. You can get this at many garden centers. A good mail-order source is Gardens Alive (www.gardensalive.com).

    Hi!
    We live in Fort Worth, Texas and I am having quite a time with our Bat Face. As I understood it when I purchased them, they are to grow very large and plenty of blooms…the foliage is yellowish and brittle, yet there are pretty blooms on it. My Plumbangos are the same, any suggestions?

    It sounds like your plants are just a little tired after going through another hot summer. Try cutting them back by 6 inches or so and feeding them with a water soluble fertilizer like Miracle-Gro. They should perk up.
