OK... so last year I tried planting garden cosmos for the first time. Lots of people in my neighborhood grow them - they're so pretty and they bloom all summer long.
So I started some from seed and transplanted them... and, well, they did OK, but not great.
The main problem was that they just didn't form many flowers, and they didn't bloom until September.
I figured that perhaps I just got them in too late, so this year I scattered a bunch of seeds early in the spring. Now we had TONS of rain this spring, so I know they got plenty of water, but most just didn't sprout. Finally a few plants sprouted, but once again, they grew really slow and produced no flowers.
This one STILL has no flowers, though it does finally have one tiny bud.
So here we are in November, and one plant is finally starting to bloom.
Still... it's pretty pitiful! But here's the thing. The plant itself is lush and green with big "branches" instead of the tall spindly stems that most cosmos flowers have. It's like all of the energy went into the plant and none into the flowers.
It can't be the climate because my neighbors have cosmos that have been blooming since June with TONS of flowers. I've read that if you fertilize them or water them too much, or if they don't get enough sun they can fail to bloom... but I didn't fertilize at all, they're in full sun, and I honestly didn't water at all most of the summer.
So I'm just flummoxed!
Anybody have any experience growing garden cosmos? I'd be grateful for any advice that anyone might have!
