Growing pepper in zone 8b
Zone 8b has an average last spring frost around Mar 15 and a first fall frost around Nov 20, giving roughly 250 frost-free growing days. That window comfortably fits pepper's 70-day cycle, with room for a second succession planting if you time it right.

Zone 8b specific growing notes
In zone 8b (Austin TX, Savannah GA), your 250-day growing season means pepper should be planted only after the soil has thoroughly warmed. Warm-season crops like pepper need soil temperatures of at least 60°F. In zone 8b's climate, using black plastic mulch can warm the soil 2-3 weeks earlier.
Your first fall frost around Nov 20 means your last possible harvest is roughly late Nov. For a continuous supply, consider succession planting every 2-3 weeks from Mar 29 through mid-season.
Pro tip for pepper
Bottom-heat mats speed germinationâpeppers need 80-85°F soil to sprout reliably. Once fruiting, pick the first peppers when slightly under-ripe to signal the plant to produce more.
Troubleshooting pepper
Blossom drop happens when daytime temps exceed 90°F or nights stay above 75°F. Use 30% shade cloth during heat waves. Also, peppers need consistent phosphorusâbone meal at transplant helps.
Growing pepper in containers
Thrives in 3-gallon containers minimum; compact varieties like 'Lunchbox' or 'Cajun Belle' fit 2-gallon pots. Peppers actually prefer being slightly root-bound for heavier fruit set.
Can you plant pepper twice a year?
Not recommendedâpeppers require a long warm growing season and slow down as days shorten. Focus on one strong crop per year in most zones.
