“Weed and Feed” – Okay on Flowers?
Q: Can you use “weed and feed” on flowers? I have applied it on some of mine. Are they going to die?
A: It depends on which kind of “weed and feed” you used. Some products contain fertilizer plus a crabgrass preventer. These would not likely hurt your flowers. Preen ‘n Green is a product specifically designed to fertilize flowers and prevent weeds. Other products contain fertilizer and broadleaf weed killers. These would almost surely hurt your flowers.
If you used the latter product, dig up your plants, wash the soil from their roots, plant in a new spot and keep your fingers tightly crossed.
