RIGHT NOW
Wait before planting outdoors
The next recommended Bowie-area window is May–mid-June. Harden off transplants and wait until nights are mild. Direct-sown seed germinates poorly in cold soil.
Basil is a heat-loving annual. Bowie’s safest outdoor start comes after the average last frost, once the soil and nighttime air have warmed.

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
Warm September days can sustain harvest, but cool nights slow growth and frost rapidly blackens the tender foliage.
Normal Right Now
- ✓
A sudden collapse immediately after frost is normal end-of-season injury for basil.
- ✓
Before frost, upper leaves should remain fragrant and green even if older leaves yellow.
- ✓
The exact pace for basil can shift with sun, planting age, pruning, and Bowie-area weather.
Something Looks Different?Signs that may be worth investigating
Worth Checking
- Dark leaf lesions with fuzzy growth beneath leaves
- Blackened foliage without recent frost
- Persistent wilt in a moist root zone
- Severe stem collapse at the soil line
These signs may be worth investigating. A symptom or photo alone cannot identify the cause.

University of Maryland Extension · Care of Herbs and Starting Herbs from Seed Last reviewed: September 3, 2026This 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
Cold nights, saturated soil, and basil downy mildew can end a crop quickly. Choose resistant cultivars when available.
