Hello,
I am a rank beginner.
I planted seeds on July 1st. It was a mix of random seeds (see package).
Now they're sagging. Some are annuals, and some perennials? Which are which?
What should I do? trim them? pull them out? leave them alone?
thanks a lot for your advice.

hi, You did pretty well!
What is your winter climate?
Annuals tend to bloom as long as they can, eventually die either due to exhaustion or freeze.
Perennials can survive freeze, by letting their tops die but growing new stems from the roots when weather gets warm again.

Just remove any that get dry, too ragged etc. If there are dry seeds on stems you take out, toss them back on the garden.
