When to Plant Pansy in USDA Zone 9b
Your June game plan for Zone 9b
Here's what deserves your attention in Zone 9b this month. Everything below is tailored to Zone 9b and timed around your local frost dates.
Pansies (Viola × wittrockiana) are beloved cool-season annuals offering some of the widest color range in the annual garden. Their cheerful "faces" appear in early spring — or even late winter in mild climates — and hold up remarkably well through frosts. Heat causes them to go leggy and stop blooming; replace with warm-season annuals once daytime temps exceed 70°F.
In Zone 9b, the average last spring frost is around January 25 and the first fall frost is around December 20, giving you a growing season of approximately 329 days.

Growing Tips for Pansy in Zone 9b
Zone 9b offers a long growing season (~329 days). You can plant Pansy earlier and may get multiple harvests.
Start indoors 10-12 weeks before last frost for spring transplants. In zones 6+, fall planting (8-10 weeks before first frost) gives overwintering plants that bloom earliest in spring. Plant in full sun in cool weather; afternoon shade helps extend bloom in zones 7-8. Deadhead to prevent premature seed set. Shear back by one-third when plants go leggy to extend the season.
