Growing Pepper (Bell)
in White Oak, Texas

Why grow Pepper (Bell) in White Oak?

Summer highs reach 93°F (NOAA NCEI) and winter lows fall to 34°F, at 381ft elevation (USGS). Pepper (Bell) prefers USDA zones 3–11, killed below 55°F. The zone fits comfortably — the challenge here is humid-summer disease pressure, not temperature. Surrounding metros — Gladewater, Houston, and San Antonio — share the same climate, so this guide largely applies to them too.

The 175-day growing season (Apr 20 to Oct 15) gives you plenty of runway for pepper (bell), which take 70–90 days to mature. White Oak averages 2700 hours of sunshine annually with 1200 chill hours per winter — pepper (bell) only need 6–10 hours daily, so light is never the problem. The game in White Oak is managing the humid August disease wave.

Metro-wide climate notes: Gladewater and Houston sit in the same zone 6b humid subtropical basin as White Oak, while San Antonio at slightly higher elevation runs 2-3°F cooler in winter. Dallas in the lower valley shares White Oak's frost dates almost exactly. The pepper (bell) growing strategies in this guide apply across the entire metro.

Fertilizer

Pepper (Bell)s are a medium feeder. Use a 05-10-2010 (matched to flowering-and-fruiting stage) fertilizer once flowers appear. In containers, nutrients leach with every watering — feed weekly at half strength rather than monthly at full.

Sun

Pepper (Bell)s need 6–10 hours of Full Sun. In White Oak, morning sun with light afternoon protection during heat waves keeps plants productive without scorching.

Pests & diseases in White Oak

Companion plants & what to avoid

Good companions: basil; tomato; carrots; onion; spinach; marigold; nasturtium.

Avoid planting with: fennel; kohlrabi; brassicas (in nutrient competition).

Pollination: Pepper (Bell)s are self-pollinating — a single plant will set fruit on its own. White Oak's humid summer mornings can clump pollen; midday hand-pollination helps fruit set.

Wildlife & pet safety

Deer pressure in White Oak: high (urban metro). Pepper (Bell)s are not deer-resistant — fencing recommended in higher-pressure suburbs.

Pet safety: Toxic to cats: No · Toxic to dogs: No. Non-toxic per ASPCA; fruit and foliage considered safe though large amounts may cause GI upset
