A succession planting calendar helps you replace finished crops instead of leaving beds empty. Use the crop-by-crop guide below to match harvest dates with frost windows, soil space, and the next suitable vegetable, then record each sowing so your garden plan improves throughout the season.
Overview
Succession planting means scheduling several crops in the same space during one growing season. You might sow lettuce every two weeks, plant bush beans after spring peas, or follow an early potato harvest with a fall crop. The goal is not to keep every bed full at all times; it is to make deliberate use of available space while allowing enough time for each crop to mature.
The most useful question is: what can I plant after harvesting this crop? The answer depends on four factors:
- Time remaining: Compare the expected days to maturity with the number of frost-free days left.
- Temperature: Choose cool-season crops for declining temperatures and heat-tolerant crops for summer conditions.
- Space and soil: Remove spent roots, refresh the bed, and avoid repeating the same crop family in the same position when possible.
- Crop purpose: A quick crop for baby leaves may fit where a full-size cabbage would not.
Days to maturity on a seed packet are estimates, not guarantees. They may be counted from direct sowing or transplanting, and cool weather, shade, drought, pests, and poor soil can slow growth. Use the packet’s information as a planning range, then add a margin rather than planting on the final possible date.
For a broader layout, pair this calendar with a raised garden bed planner or the guide to planning a productive garden layout.
What to track
A simple garden record is more useful than a complicated spreadsheet if you update it consistently. For each planting, record the crop, variety, location, sowing or transplanting date, expected maturity, first harvest, and final harvest. Add notes about heat, frost, pests, disease, and whether the crop occupied the bed longer than expected.
Use this printable-style table as a starting point. The follow-up crops are broad options; select the one that suits your local season and remaining growing time.
| Crop being cleared | Typical growing window | What to do after harvest | Possible follow-up crops |
|---|---|---|---|
| Peas | Cool season; often about 55–75 days | Remove vines and roots unless they are diseased; clear the support. | Bush beans in warm weather; carrots, beets, or leafy greens as temperatures cool. |
| Radishes | Fast crop; often about 20–35 days | Harvest promptly before roots become woody or pithy. | Another radish sowing, salad greens, baby carrots, or a later transplant. |
| Lettuce | About 30–70 days, depending on type and harvest size | Pull bolted plants and remove damaged leaves. | More lettuce in cool weather; bush beans, cucumbers, or fall greens when conditions change. |
| Spinach | About 35–50 days; prefers cool conditions | Harvest before prolonged heat if it begins to bolt. | Warm-season beans or basil in summer; kale, spinach, or Asian greens for a later cool season. |
| Early potatoes | Often about 60–90 days | Lift all tubers, remove volunteer plants, and rake the bed level. | Bush beans, carrots, beets, or a fall brassica transplant where time allows. |
| Garlic | Overwintered; harvested in early or midseason | Dry the bulbs, remove leftover leaves, and loosen the surface soil. | Bush beans, cucumbers, summer squash, or a quick cover crop. |
| Onions | Varies widely; commonly a long-season crop | Cure harvested bulbs and clear roots before replanting. | Leafy greens, beets, carrots, or a fall crop suited to the remaining season. |
| Bush beans | Often about 50–60 days | Remove plants after production drops; do not compost visibly diseased material. | Fall lettuce, spinach, kale, radishes, or overwintering onions where appropriate. |
| Early carrots or beets | Often about 50–75 days for smaller roots | Harvest usable roots and remove tops from the bed. | More root crops if the soil is loose; lettuce, cilantro, or fall brassicas. |
| Early cabbage or broccoli | Often about 55–90 days after transplanting | Remove the entire plant and inspect for clubroot or other soil problems. | Fall cabbage, kale, lettuce, or a non-brassica crop such as beans. |
Do not treat the table as a fixed regional calendar. In a short-season or cool climate, a summer sowing may need to be transplanted rather than started outdoors. In a long, warm season, a crop listed as a late-season option may still be planted later. Use your local average last spring frost and first autumn frost as planning markers, then confirm the crop’s temperature preferences.
Cadence and checkpoints
Check succession plantings once a week during the active growing season. A weekly walk is frequent enough to catch bolting, gaps, pest damage, and harvest-ready crops before the next planting window closes.
At sowing
Write down the date, variety, row length, and expected harvest range. Mark the bed with a label that will remain readable after watering. If you are sowing a quick crop in a space occupied by a long-season plant, record the intended clearance date as well.
At the first harvest
Estimate how long the crop will continue producing. A bed of lettuce may be cleared in one day, while beans or tomatoes may occupy the space for weeks after the first harvest. Start the next crop in modules or a seed tray if the bed will not be ready immediately. This is especially useful for fall crops, whose planting window can be narrow.
At final harvest
Remove spent plants, roots, weeds, ties, and labels. Check the soil for compaction and add finished compost if the bed needs organic matter. Do not plant a new crop into soil that is waterlogged, contaminated with diseased debris, or still crowded with old roots. Water the prepared bed and plant as soon as conditions are suitable.
At the seasonal change
About four to six weeks before the expected first autumn frost, review every empty space. Prioritize crops with short maturity times, such as radishes, baby greens, and some lettuce varieties. For a more complete monthly plan, use the seasonal gardening checklist.
How to interpret changes
If a succession crop repeatedly fails to mature, first compare the planting date with actual weather rather than assuming the variety is unsuitable. A cool spring can delay beans and cucumbers; intense heat can cause lettuce and spinach to bolt; shortening days can slow late plantings even when temperatures remain mild.
When a crop is consistently late, choose a faster variety, transplant sturdy seedlings, or shorten the harvest goal. For example, plan to harvest baby kale rather than full-size plants when only a few weeks remain. Row covers, shade cloth, and mulch may help moderate conditions, but they do not replace a realistic frost-window calculation.
Use crop rotation as another interpretation tool. Planting the same family repeatedly can increase the chance of recurring soilborne problems and pest pressure. After peas or beans, follow with a crop from another family rather than another legume. After cabbage, broccoli, or kale, consider lettuce, beets, carrots, or beans instead of another brassica. Rotation is easier in a small garden when you record plant families, not just common crop names.
Soil observations also matter. A bed that supported heavy-feeding crops may benefit from compost before another demanding crop. A bed that stayed wet may need improved drainage before planting roots. Keep amendments modest and based on the soil’s condition; more fertilizer is not automatically better succession planning.
When to revisit
Revisit this succession planting calendar at four practical points: before the first spring sowing, after the first major harvest, roughly one month before the first expected autumn frost, and at the end of the growing season. A monthly review is worthwhile in a productive garden because harvest dates often shift by a week or more.
At each review, update three items:
- Actual maturity: Compare the packet estimate with the date you first harvested a useful crop.
- Available space: Mark beds that will be cleared soon and note whether they need compost, support removal, or pest cleanup.
- Weather window: Recheck the remaining frost-free period and choose crops that can finish within it.
To put the system into practice today, choose one bed and write down its current crop, expected final harvest, and three possible follow-up crops. Start the earliest suitable option in a tray if necessary, prepare the bed as soon as it clears, and add the actual harvest date to your garden record. Repeat that short process each week. Over time, your own notes will turn this general vegetable garden planting schedule into a succession plan suited to your soil, climate, and available time.
