The Q&A Archives: Encouraging Trumpet Vine Blooms

Question: from destroying them? Thanks. Pat Michigan

Answer: None of the sources I consulted mentioned anything about a 5 year wait for flowering. I'm wondering if perhaps that afternoon shade is the culprit. Though the vine itself will grow well in a partial shade situation, full sun in best for flowering. If there's nothing you can do to increase the afternoon sun (such as removing an overhanging tree branch), then I guess you'll just have to be patient and see if the plant will flower when it is more mature. Be sure that you are not feeding the plant with a high nitrogen fertilizer--nitrogen encourages foliage growth at the expense of flowering. One way to reduce earwig populations is to trap them. You can set out rolled up newspapers near the base of your plants. The earwigs will crawl into the newspaper and, in the morning, you can shake them out into a pail of soapy water. If the earwigs are indeed harming your plants, and not just a nuisance, there are pesticide sprays on the market that will kill them; check at your local garden center and follow label directions carefully.
