RIGHT NOW

Wait before planting outdoors

The next recommended Bowie-area window is May–mid-June. Rosemary is only occasionally winter-hardy in Maryland. A container makes frost-free winter protection practical.

Plant after hard-frost danger so roots enter warm, fast-draining media. In Bowie, rosemary is safest as a container plant that can move indoors.

CURRENT STAGE

Late Harvest / Frost Preparation

Typical stage for September in Central Maryland

Rosemary remains green as growth slows; it does not normally shed all foliage for dormancy.

Normal Right Now

  • Shorter new shoots are normal as light and warmth decline.

  • Foliage should stay aromatic and attached before cold injury occurs.

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

Something Looks Different?Signs that may be worth investigating

Worth Checking

  • Needles browning inward while soil stays wet
  • A soft dark crown or collapsing roots
  • Heavy scale, whitefly, or spider-mite activity indoors
  • Sudden whole-plant browning after freezing

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

WHAT SHOULD YOU DO NOW?

Move the pot to frost-free protection before hard freezes.

See Rosemary Through the YearA typical Bowie-area lifecycle

December–March

Protected Overwintering

Container rosemary stays evergreen indoors or in frost-free protection, with slower extension under winter light.

April–May

Renewed Growth

Fresh pale-green shoot tips extend from the evergreen framework as days brighten.

June–August

Active Growth / Harvest

Dense needle-like foliage develops on branching woody stems and may carry small pale blue flowers.

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

Most common culinary cultivars are not reliably winter-hardy in an exposed Bowie container, and indoor overwatering is a frequent cause of loss.

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.
