Start harvesting pansy
Morning harvests are best — cooler temperatures mean crisper produce and longer fridge life.
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.
Montgomery County, Texas is in USDA Zone 9a. The average last spring frost is February 18 and the first fall frost is December 1, giving you a growing season of approximately 286 days.
At an elevation of 180 feet, Montgomery County receives approximately 62.1 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96°F, so Pansy may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Pansy will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Pansy root diseases.

Pansy Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Growing Tips for Pansy in Montgomery County
Direct sow Pansy outdoors after February 18 in Montgomery County when soil has warmed and frost danger has passed.
Sandy soil in Montgomery County dries quickly — mulch Pansy with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

General growing tips
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.
