Post #9244712

I have a thyme plant that shares a window box with a rosemary plant. In the past week, the thyme plant has changed dramatically. The leaves are yellowing and thinning out, and the entire box is absolutely crawling with those reddish-brown centipedes.

There's been no change in water, sunlight, or the introduction of any new foods / soils / chemicals since this started happening.

I've been doing some reading, and it seems that the centipedes are PROBABLY not eating the thyme roots, but may be eating other root-eaters. But if that's happening, why aren't they taking care of the problem? And why is the rosemary perfectly fine?

I'm getting food grade diatomaceous earth delivered to me on Wednesday, but I'm afraid the plant will be dead by then.

Can anyone help me figure out what's going on and what I should do? Thanks in advance!!

Can you post some pictures of the centipedes (and the thyme)? The centipedes may just be a coincidence and not related to the problems you're having. In my personal experience, thyme seems to be more sensitive to excess moisture than rosemary, so it's possible you've been watering the window box a little too much and the symptoms are showing up with the thyme first. Just because you haven't changed your watering habits doesn't mean that you haven't been watering a bit too much all along and it's just starting to catch up to you--unless you're totally drowning them, plants will sometimes seem to be fine for a while before they start to show symptoms of overwatering.

Cool weather, stop watering, and they need trimmed to encourage growth, buteo be planted too closely together, the yellowing does sound like a moisture issue.

yes, too much moisture and centipedes will take advantage of that environment.

Need good air circulation, the roots of the plants could be crowding each other out as well- we like to give our Rosemary room- for the sake of the other plants needs!
