My Wave Petunias are starting to seed. Why is this happening?
Wave Petunias will seed, however, as long as you fertilize and water them, they will continue to grow and bloom normally.
If you continue to fertilize your plants, new growth will appear within 2 weeks. If they start looking "stringy," cut them back a few inches as long as you continue to fertilize them twice a week. It will most likely take at least 10 to 14 days to see results.
