Plants That Do Not Bloom

Question

Last year I grew beautiful morning glories in containers. Seeds that overwintered in the pots are growing into large, extensive and healthy vines – but no blooms. I have fertilized several times. No blooms at all. It’s getting late in the season. Should I give up and rip them out?

Answer 1

It's quite possible that they're getting too much fertilizer, especially nitrogen, which promotes more foliage growth than flowers. It can also reduce the viability of seeds. Ease up on the fertilizer or use one with more phosphorus, which promotes flower growth. Also, you may want to start plants earlier. It could be that they had a late start.
