Spring-Planted Bulbs and Summer Blooms: A Guide to Growing and Storing Dahlias, Gladiolus, and More - Ep. 301
What's in this episode
A listener asked for a deep dive on dahlias and I’m delivering, from the ground up (pun intended). But we’re not stopping there. In this episode, I’m covering the full world of spring-planted bulbs: dahlias, gladiolus, cannas, calla lilies, and tuberous begonias. You’ll learn when and how to plant them, how to grow them for maximum blooms, how to cut them for the vase (because that’s half the fun), and, critically, how to handle end-of-season care based on where you live. If you’re in a warmer zone, some of these can stay in the ground. If you’re in a colder zone like me, we’re digging them up, curing them, storing them, and doing it all again in the spring. Let’s dig in! Quick-Reference: Zone-Based Overwintering Guide Zone 9-10+: Leave everything in the ground. Mulch lightly after frost. Let plants rest and re-emerge in spring. Zone 8: Cannas and callas can stay with heavy mulch. Dahlias and glads: consider digging, especially in colder parts of the zone. Zone 7: Mulching is a gamble. Reliable: dig dahlias and glads. Cannas may survive with very heavy mulch in milder Zone 7. Zone 6 and colder: Dig everything. Cure properly. Store in cool, dry, dark, frost-free conditions. Replant
