Getting started
Sowing and space
Plant disease-free, locally appropriate cloves at the depth and orientation stated by the supplier.
Allow about 9.8 in (25 cm) of usable depth and roughly 4.7 in (12 cm) between plants.
Watering reference: low to moderate. Adjust to rain, heat, wind, growth stage and container volume.
Planting windows by broad profile
These original editorial windows compare thermal groups, not live weather. Check current frost, heat, rainfall and packet directions.
Very cold, short season
Use actual frost-free conditions, soil temperature, and short-season cultivars; a listed month alone is not enough.
Winter survival and spring planting options require local Extension guidance.
Cold winter, warm summer
Local last and first frost, lake effects, elevation, and urban heat can move the usable window by weeks.
Hot and humid
Favor cool crops outside peak heat and protect warm crops from the last local freeze rather than following the month alone.
Mild marine
Watch soil warmth, drainage, direct sun, and local wind; inland valleys can differ markedly from the coast.
Dry summer, mild winter
Use cool months for leafy crops and account for heat waves, wildfire smoke, irrigation rules, and local frost pockets.
Arid or high desert
Treat windows as irrigated-garden references and verify elevation, frost, extreme heat, wind, and current water rules.
Tropical or frost-light
Choose timing around local rainfall, disease pressure, storms, and heat; high-elevation tropical sites may belong elsewhere.
Low-chill cultivars and local timing are essential; the general window may not apply at elevation.
Practical care
- Keep the bed weeded during early growth.
- Reduce watering as mature tops naturally dry, following local guidance.
Points to check
- Grocery cloves may be unsuitable or carry disease.
- Poor drainage can rot bulbs.

United States Department of Agriculture, Agricultural Research Service
Supports treating average annual extreme minimum temperature as one cold-risk reference, not a complete planting calendar or current forecast.
U.S. Climate Normals
NOAA National Centers for Environmental Information
Supports the use of long-period climate context and the warning that station and regional conditions vary; it does not supply operational month rows.
Vegetable Gardening
USDA National Agricultural Library
Supports the planning sequence of site selection, soil or mix preparation, planting, maintenance, and harvest, plus referral to Cooperative Extension.
Seeds and Plants
USDA National Agricultural Library
Supports checking labeled seed from reputable sources and distinguishes planting material quality from a calendar recommendation.

USDA Animal and Plant Health Inspection Service
Supports checking import and movement requirements and avoiding unidentified or non-compliant seed bought online.
Use it in context
A month alone cannot resolve cultivar, soil, microclimate or a current extreme.
Use reputable planting material. Use reputable domestic seed or plants and check current USDA APHIS and state restrictions before moving or importing plant material.
If a pesticide is considered, use only a product registered for the site and crop and follow the complete EPA-approved label and applicable state requirements.
