Mexican Petunias/Ruellia

Anonymous added on July 16, 2011 | Answered

I moved into my home 5 years ago and inherited two beautiful batches of Ruellia. They bloomed wonderfully the first two years, but over the last three years less and less. This year I have no blooms. The plants appear to be completely healthy. There is adequate sunlight, good soil, the right amount of water, no visible pests, the leaves are normal (green/not wilted) and so on. I have tried everything to figure out what's wrong. What is it that I'm not thinking of? I've tried fertilizing/not fertilizing, watering/not watering, compost/sand and still nothing. Any info appreciated.

There are a couple of possiblities. Your plants may need thinning because they've put too much energy into spreading, or your plants have become sterile. Try thinning them out.
