Do you replace your container soils each year?
Do you replace the potting soil in your containers each year? Maybe just refresh it by adding some fresh new potting soil?
I have two pkts. of mixed flower seeds that look like they would be perfect for some of my containers. I am tempted to direct sow them in one of my urns. Even though the temperatures are staying about low 40's, do you think it is too risky to direct sow them now? I think our last frost date is considered 4/22..or should I just wait until then.
