Just make sure the roots are not going around at the bottom. If they are then loosen them so they hang down. Then give them a gentle squeeze from side to side and plant. So the answer is reasonably careful, but Marigolds have a large, strong root system so they are not ones you have to be extra careful of.. The ones you buy are always pot bound. Yours may not be, so just have a look at them and decide.

Thanks Oilpainter !

Now I just need to find a drill bit to put holes in my yogurt containers, and then Plant =:)

I'm soooo excited !

You're welcome nutsaboutflowers:

I might add that the same goes for any plant you buy or grow annual or perennial. If the roots are a tangled mess on the bottom--if they are going round and round at the bottom. That means they are pot bound and you have to loosen them so the plant can take up nutrients from the soil. Otherwise they will continue to be a tangled mess in the ground and the plant can't get what it needs to grow.

Oilpainter I knew that plant roots need to be "disturbed" if they're root bound, but thanks for telling me, in case I didn't know. =:)

The only annual I've ever had trouble with is marigolds. I posted last year that my marigolds embarrassed me, and suggestions from that post led me to be rather nasty to them when I planted them. They thrived for the first time.

BTW I transplanted 4 of my seedlings to see what happens. I may have given them too much water. In two days, if they're O.K. I'll do some more. I didn't have enough courage to try all 14 of them.
