Buy plants....
Figure about a week at the shortest time for the seeds to sproout...that takes us to June 12th. Another 4 days at the least for the plants to get their second set of leaves...we are not at June 16th at the earliest.
That leaves 15 days for the plants to grow 3 or 4 more sets of leaves, set buds and bloom....
Not gonna happen...best to buy and get on it very soon as plants go into transplant shock and wait a while before resuming blooming.
I would be seriously thinking of the plants in the gallon post and just sit them around.

Thanks Linda. That's exactly what my thoughts were after reading everything that I could online. My mil told me to just sprinkle my seeds and let them take off. I disagree but wanted to give the benefit of the doubt. lol

I know that I can get marigolds, petunia, and few other traditional bedding plants for my area and add them in wherever I need some color. We're a bit cooler for a few days here, so the timing is perfect!

Thanks for the advice!! LC Grace
