Use this regional month-by-month planting calendar to decide what to sow, transplant, harvest, and record in a small vegetable or herb garden. The guide combines frost-based timing with a reusable seed-starting template, so you can adjust dates for your climate rather than follow a fixed calendar that may not fit your area.
Overview
A reliable planting calendar begins with two local reference points: your average last spring frost and average first autumn frost. These dates are planning estimates, not guarantees. A sheltered urban garden, exposed hillside, coastal yard, and low-lying frost pocket can all experience different conditions even within the same growing zone.
For a beginner garden, divide crops into three groups:
- Cool-season crops: vegetables such as peas, lettuce, spinach, radishes, carrots, onions, and many brassicas. These tolerate cool soil and can often be sown before warm-season crops.
- Warm-season crops: tomatoes, peppers, eggplants, beans, cucumbers, squash, and basil. These need warmer soil and are more vulnerable to frost.
- Perennial or hardy herbs: chives, mint, oregano, thyme, sage, and some varieties of rosemary. Their planting and overwintering needs vary, especially in containers.
Before choosing dates, note your garden’s sunlight, container or bed size, drainage, and access to water. A small space is usually more productive when it prioritizes crops you regularly eat and uses succession sowing instead of planting everything at once.

What to track
Your local timing markers
Record the estimated last frost in spring and first frost in autumn, then write down the actual dates when they occur. Also track soil conditions. A calendar date may say it is time to plant, but cold, wet soil can delay germination and encourage rot. Observe when the soil is workable, when it dries after rain, and when nighttime temperatures become consistently suitable for tender plants.
Month-by-month planting calendar template
Use the following as a flexible framework. Replace “frost date” with your local estimate and shift the tasks earlier or later according to your climate.
| Period | Planning and planting tasks |
|---|---|
| Late winter | Review last season’s notes, order or sort seeds, clean containers, test stored seed, and sketch beds. Start slow-growing crops indoors if they need a long lead time. |
| One to two months before last frost | Start selected cool-season transplants indoors. Prepare trays and labels. Check lights, airflow, and watering habits rather than overcrowding seedlings. |
| Four to six weeks before last frost | Sow hardy crops outdoors when soil is workable, or protect them with row cover. Start peppers, eggplants, and other slow warm-season crops indoors if appropriate for your region. |
| Last-frost window | Harden off indoor seedlings gradually. Direct-sow peas, carrots, radishes, lettuce, and other cool crops as conditions allow. Do not treat the last-frost date as a signal to plant every crop. |
| One to three weeks after last frost | Transplant hardened-off tomatoes, peppers, basil, cucumbers, squash, and beans once soil and night temperatures are suitable. Sow a small second planting of quick greens or radishes. |
| Early to midsummer | Succession-sow beans, salad greens, radishes, carrots, and herbs according to crop speed and heat tolerance. Mulch after the soil warms, monitor moisture, and provide support for climbing plants. |
| Late summer | Begin fall crops such as greens, radishes, turnips, and some brassicas. Count backward from your expected first frost using the seed packet’s maturity guidance, allowing extra time for short days or cool weather. |
| First-frost window | Harvest tender herbs and warm-season crops before frost. Cover crops that can tolerate brief cold, and bring suitable container herbs indoors after checking for pests. |
| Late autumn and winter | Clear diseased plant material, leave healthy roots or cover crops where useful, protect perennial herbs, clean tools, and record what germinated, bolted, struggled, or produced well. |
Quick crops versus slow crops
| Crop type | Examples | Usual method | Timing notes |
|---|---|---|---|
| Quick, cool-season | Radishes, baby lettuce, arugula | Direct sow | Sow small amounts repeatedly for a steadier harvest; heat can reduce quality. |
| Quick, warm-season | Bush beans, some cucumbers | Usually direct sow | Wait for warm soil. Make a second sowing if space and season length allow. |
| Slow, tender crops | Peppers, eggplants, some tomatoes | Start indoors, then transplant | Allow time for gradual hardening off. Protect from cold nights. |
| Root crops | Carrots, beets, turnips | Direct sow | Transplanting can disturb roots; prepare a fine, stone-free seedbed. |
| Leafy herbs | Basil, cilantro, parsley | Direct sow or transplant | Basil prefers warmth; cilantro may bolt quickly in heat, so sow it in intervals. |
| Hardy herbs | Chives, thyme, oregano | Transplant or divide | Provide drainage. Mint is best contained because it can spread aggressively. |
Seed-starting worksheet
For each crop, fill in the following fields before the season begins:
- Crop and variety: Include whether it is suitable for containers, raised beds, or limited space.
- Local frost reference: Write your estimated last spring frost or first autumn frost.
- Weeks before or after frost: Use the seed packet or nursery guidance as a starting point.
- Planned sowing date: Add a reminder to your calendar.
- Expected transplant or harvest window: Keep this approximate; weather can shift maturity.
- Follow-up sowing: Note whether you will repeat the planting in two to four weeks.
- Result: Record germination, pest pressure, harvest length, and whether you would change the timing.
Cadence and checkpoints
Check the garden briefly once or twice a week during the growing season. Look at soil moisture below the surface, seedling growth, weeds before they set seed, leaf damage, and whether plants are ready for harvest. A short note is more useful than relying on memory.
At the start of each month, complete four checks:
- Review the next four weeks of sowing and transplanting tasks.
- Make room for succession crops by identifying beds that will soon be cleared.
- Inspect supports, irrigation, row covers, containers, and hand tools.
- Adjust the plan for heat, drought, excessive rain, or a late frost instead of forcing plants into unsuitable conditions.
Every quarter, review crop rotation and soil management. Moving plant families between beds can reduce repeated pressure from some pests and diseases. The guide Crop Rotation for Small Vegetable Gardens provides a simple way to organize this change.
How to interpret changes
If seeds germinate slowly, first check soil temperature, moisture, planting depth, and seed age before changing the crop. If seedlings become tall and weak, they may need stronger light, better spacing, or gentler watering. If a crop repeatedly bolts, wilts, or produces poorly, the answer may be timing rather than soil fertility.
Use patterns across seasons. One failed sowing may reflect unusual weather; repeated failure suggests a planning adjustment. Try an earlier or later sowing, a heat-tolerant or short-season variety, partial afternoon shade, or a container that can be moved. In dry climates, prioritize mulch, deep watering, and drought-tolerant choices. In wet climates, prioritize drainage and airflow.
Frost sensitivity deserves special attention. Lettuce, peas, spinach, parsley, and cilantro generally handle cooler conditions better than basil, beans, cucumbers, peppers, and tomatoes. Even relatively hardy crops can suffer when exposed to prolonged freezing, so use local observations and protect plants when a cold snap is forecast.
When to revisit
Save or print this calendar before each growing season, then update it when your local frost estimates, hardiness guidance, or seed availability changes. Revisit the plan monthly during active growth and after any unusual weather event. At season’s end, keep a one-page record of actual frost dates, sowing dates, harvest timing, pest problems, and the varieties that performed best.
Before planting next year, use those observations to create a shorter, more accurate schedule. Start with crops your household will eat, reserve space for at least one succession sowing, and leave some flexibility for weather. For compact spaces, the Best Garden Tools for Small Spaces can help with routine planting and maintenance.
Next step: choose one bed or container today, write down your local last-frost estimate, and fill in dates for three crops: one cool-season direct sowing, one slow indoor-started crop, and one herb. Check those entries weekly, record what actually happens, and let your own garden’s evidence improve the calendar each season.
