I have just started growing my own plants from seeds. I have cosmos seedlings but I’m not sure if they should be so tall if I’ve done something wrong.
They're fine ☺. When you pot on or plant out, you can plant a touch deeper to bury a little of the stem upto first leaves. Ensure they get lots of light, not too much direct sun over this weekend.
Thanks wasn’t sure if they’d gone too leggy to do anything with.
