RIGHT NOW
Wait before planting outdoors
The next recommended Bowie-area window is First–third weeks of April. Approximate Central Maryland outdoor planting period. Check weather, soil conditions, and the cultivar before planting. Kale may also be transplanted. Fall crops often hold into winter and improve in flavor after cool weather.
Approximate outdoor calendar for Central Maryland. Early, mid, and late-month source wording is represented by calendar dates; confirm the cultivar, local weather, soil, and production system.

TIME TO HARVEST
40–80 days
Count from: sowing seed
General leafy-green range for full-size leaves; young leaves can be cut earlier. Leave the growing center for repeat picking. Check the cultivar packet for a more specific interval.
Approximate guidance, not a guaranteed harvest date. Cultivar, plant size, light, temperature, and care affect timing. For perennials, first harvest does not mean full production. Follow the plant tag and check readiness before picking.
SEASONAL REFERENCE
What Should This Plant Look Like Now?
October Central Maryland
CURRENT STAGE
Fall Growth / Harvest
Typical stage for October in Central Maryland
The plant carries a firm central rosette of curly, flat, or deeply cut leaves; cold can deepen color and sweetness.
Normal Right Now
- ✓
Cool nights can deepen kale color or sweetness without signaling failure.
- ✓
The crown and inner leaves should remain firm through normal light frost.
- ✓
The exact pace for kale can shift with sun, planting age, pruning, and Bowie-area weather.
Something Looks Different?Signs that may be worth investigating
Worth Checking
- A missing or rotted central growing point
- Severe caterpillar feeding across new leaves
- Large clubbed roots with chronic wilting
- Rapidly spreading black-edged leaf lesions
These signs may be worth investigating. A symptom or photo alone cannot identify the cause.

Pins show selected countries in the documented native range; the source lists the full range. This records species ancestry, not where a garden variety was selected.
Before you choose it
A three-gallon pot is a minimum for one mature plant. Dense stands are appropriate only for planned baby-leaf harvest.
