How to Grow a Successful Spring Garden
A successful spring flower garden starts with knowing when to plant your seeds - understanding that timing starts with your USDA Hardiness Zone.
Not sure when to plant your Cool Flowers (a.k.a. cool-season hardy annuals)? This downloadable (and printable!) guide organizes our recommended flower varieties by USDA Hardiness Zone 3–10, giving you a quick reference for what to plant and how to get started.
You'll find:
- Organized seasonal planting guidelines for USDA Hardiness Zones 3–10
- Zone-specific timing for fall, very early spring, and summer planting
- Seed-starting tips for indoor seed-starting & direct sowing
- Zone-specific planting tips to improve germination and plant success
- Flower-by-flower planting lists organized by season and zone
- Expert tips and techniques from The Gardener's Workshop based on decades of growing experience
Whether you're a first-time gardener or an experienced flower grower, this guide takes the guesswork out of Cool Flower timing so you can enjoy stronger plants, earlier blooms, and a longer flowering season.
