RIGHT NOW

Wait before planting outdoors

The next recommended Bowie-area window is Mid-May–mid-June. Harden off transplants and favor warm nights. High tunnels can advance planting only when nighttime temperatures are managed.

Peppers need more warmth than tomatoes. UMD recommends transplanting all pepper types from mid-May through mid-June in Central Maryland.

SEASONAL REFERENCE

What Should This Plant Look Like Now?

September Central Maryland

CURRENT STAGE

Late Harvest / Seasonal Decline

Typical stage for September in Central Maryland

Fruit can continue coloring in September while new flowering slows; frost ends the plant rather than triggering dormancy.

Normal Right Now

  • Slower sweet pepper growth with shorter days is normal before frost ends the crop.

  • Productive upper growth can remain green while older lower leaves look worn.

  • The exact pace for sweet pepper can shift with sun, planting age, pruning, and Bowie-area weather.

Something Looks Different?Signs that may be worth investigating

Worth Checking

  • Dark sunken areas on fruit unrelated to sunscald
  • Persistent leaf curl with stunted new growth
  • Rapid wilt in moist soil
  • Heavy aphid or mite colonies on shoot tips

These signs may be worth investigating. A symptom or photo alone cannot identify the cause.

WHAT SHOULD YOU DO NOW?

Gather marketable produce and remove the crop after frost or serious disease.

See Sweet Pepper Through the YearA typical Bowie-area lifecycle

December–March

Outside the Outdoor Season

Sweet pepper is frost tender, so a living outdoor crop is not expected in Bowie during winter.

April–May

Establishment / Vegetative Growth

Sweet pepper develops new leaves, roots, and support structure after outdoor temperatures become reliably warm.

June–August

Flowering / Harvest

A compact branching plant carries white flowers and firm green fruit that may ripen red, yellow, orange, or another labeled color.

September–November · Now

Late Harvest / Seasonal Decline

Fruit can continue coloring in September while new flowering slows; frost ends the plant rather than triggering dormancy.

This is what a healthy plant typically looks like at this stage. It is seasonal reference guidance—not a visual diagnosis. Microclimate, weather, plant age, recent transplanting, pruning, and cultivar variation can change appearance.

Before you choose it

Full-color fruit takes longer than green fruit and ties up the plant; plan price and harvest stage before planting.

Bowie conditions are the baseline

Container size, microclimate, cultivar, tunnel temperature, and actual weather can move the timing. Use the plant tag and direct observation with this guide.
