The Q&A Archives: Cosmos Won't Bloom

Question: I planted new cosmos seeds this year; supposed to be pale- white with pink shading at the throat. They've grown and grown-sturdy and upright and bushy- gorgeous foliage and as of 9/5 no blooms. I swear I didn't feed them!

Answer: Cosmos usually grow and bloom with very little encouragement. They need full sunshine and very little water. In fact, they love hot, dry garden spots. Perhaps yours are getting too much water, or not enough sunshine. It's getting a little late in the season, so you may not get any blooms from them at all. If you plant cosmos again, make sure they get all day sunshine, and very little water in the summer months. Better luck next time!
