Sowing Seeds in Containers

I've always made space in my garden for sowing seeds of annuals such as larkspur, verbena-on-a-stick and gomphrena, but this year my habit has spread beyond the borders of my flowerbeds and into containers.

Because, truly, what could be easier than filling a pot with soil and sprinkling a few seeds around? That is about all it takes to create a beautiful container overflowing with colorful blooms.

The best varieties are those that can be direct sown and germinate easily. I've had luck with cosmos, heirloom petunias and cock's comb to name a few. For large containers try dwarf sunflowers or cleome. Make sure you keep the soil consistently moist while the seeds are germinating. As they grow into seedlings, you may want to thin them a bit so they don't get overcrowded.

And as an added bonus you can save seeds from many of these varieties for growing next year.

August is the time that I start collecting seeds from the annuals that are currently flowering in my garden. If you want to try your hand at seed saving just let some of the flowers mature and form seedpods. The pods are ready for harvesting when they are dry and brittle, but before they break open.

On a dry, sunny day, after the dew has evaporated, collect the seeds by shaking them onto a piece of paper. It's important to make sure the seeds are thoroughly dry before you store them in labeled, airtight, plastic bags or mason jars. Once sealed, store them indoors in a cool, dry place until you are ready to plant them in your garden or containers next summer.
