Q: I have four petunia hanging baskets. The foliage has turned light green the last few days. I water daily but how do I keep the deep green foliage?

A: If you’re using water-soluble houseplant fertilizer on the petunias, apply it more often; constant watering quickly washes out plant food. Consider using instead a slow-release, pelleted fertilizer (Osmocote, Dynamite, etc) or cottonseed meal.
