Gardening

>> I'm trying to get better about saving seeds. This year I really liked a few things that came out of a mixed seed packet from my birthday, so I'm harvesting seeds for next year. I have a some pink cosmos, bachelor buttons, coreopsis, and malope. The mini marigolds I bought have made tons of good seed heads as well. <<

That sounds awesome.

I got good seeds from small yellow and orange marigolds.

The tall landrace marigolds in orange to red have been named Shithouse Marigolds by my audience. :D Because they are built like a brick shithouse, they bloom in grass, they survive several frosts, etc.

>> I have a growing list of garden tasks that I want to get done for fall as well. The area under the burr oak doesn't grow much grass, I'm going to start a bed of hostas under it. <<

I have some hostas, and they do well under trees. I also look for native plants. And I have mini-guilds under many of my trees with daffodils, comfrey, wild onion, etc. to attract beneficial insects and discourage pests.

Look up your state and "soft landing" for native plant suggestions.
