i have cosmos growing from seed in conservatory waiting for weather to improve, they are very tall and some have flowered, should I cut them down
If they are very tall and you didn't pinch them out earlier, I'd cut them down quite a bit, then you'll get much bushier plants.
If you have a pic I'm sure we can give more accurate advice.
