About 30 days ago, I planted fresh seed of Sidalcea and perennial chrysanthemum in starter trays using starter mixture, and seedlings have not yet emerged. Thought perhaps
I may have packed soil too tightly, and used a toothpick to aerate a bit.

A whole month, and no action, hmm? Well, it could be due to the fact that Sidalcea can take up to 6 weeks to germinate, and preferes cool temperatures to sprout (around 50F). Also, seeds of perennial chrysanthemum require light in order to germinate, so don't bother covering the seeds with soil after sowing them - they should start to grow within 4 weeks time. They prefer temperatures slightly warmer than Sidalcea. Hang in there - they could still pop any day! If you have seed left over and are concerned that these aren't going to make it, try another round. If they all grow - great! You can trade with another gardener! Hope this helps!
