Q&A: No Veggies?
Q: The foliage on my plants is beautiful — no disease and insects under control — but I have almost no vegetables. I didn't apply lots of fertilizer. What could be the problem?
A: You're right; usually too much nitrogen is the culprit when foliage is healthy and beautiful but the plant fails to set fruit. In your case, the weather may be to blame. Bees and other pollinators don't do their important work in inclement weather, so it's likely that the early flowers never got pollinated. Also, tomatoes and peppers are sensitive to both cold and very warm temperatures, which cause their flowers to drop. Next year, you might try using row covers to help protect tender plants from late spring chills. Just be sure to remove the covers when it gets warm — and when you see your zucchini flowers open, so the pollinators can get to them.
