Q: I keep finding small, round, BB-size eggs in the potted flowers on my
deck. What are they and will they harm my plants? 

A: The little white balls originally contained fertilizer. To save on labor costs,
greenhouse growers fertilize their flowers with products that release fertilizer
very slowly. A common greenhouse fertilizer encapsulates nutrients in small
porous plastic balls. Once the fertilizer is gone, only the balls remain. They are
not harmful to you or your plants.
