How often should I change the soil in my windowboxes?
Can I still plant last years spring/ fall bulbs for next season?

I like to mix the old potting soil with some new, just to rivive it. The act of working in a little fresh potting soil will help loosen the old (it tends to clump in the corners and at the bottom of planters and windowboxes). Bulbs that have been sitting around in storage for a year probably won't perform well for you. Bulbs store energy for growth and the longer they sit, the less stored energy they contain. You can plant the bulbs, but there's no guarantee they will grow and bloom. I'd suggest replacing the bulbs this fall so you're assured of getting spring flowers. Best wishes with your garden.
