We filled these with soil almost a month ago. It was a sunny day that warmed our 3 season porch to temperatures that didn't merit layers of outwear. While the soil has been waiting for us for a while, we did wait a wee bit before actually planting them.
And while you're at it, start celebrating spring with friends. Talking about gardening, getting our hands dirty and planning for spring and summer. Being outside without snowpants. Oh, we're ready for all that. We're ready for you, Spring.
