A reliable succession planting plan turns a small garden or market bed into a sequence of harvests rather than a single glut. This guide gives you a reusable 12-month calendar, crop-rotation templates, interval calculations, climate-adjustment methods, and checkpoints for comparing planned dates with actual results.
Overview
Succession planting means scheduling the same crop, or a series of different crops, at planned intervals so that beds remain productive and harvests are spread over time. It can involve sowing lettuce every two weeks, planting a second block of beans after the first, or following spring peas with a fall cover crop. The aim is not to plant constantly; it is to match planting dates to crop maturity, available space, weather, labor, and demand.
Start with your local reference points rather than a fixed national calendar. Record your average last spring frost and first fall frost, then adjust for your site’s exposure, elevation, wind, soil temperature, and protection from a hoop house or greenhouse. Frost dates are planning estimates, not guarantees. Keep a buffer for unusually cold or wet conditions.
A useful plan has four layers:
- Crop sequence: what will grow in each bed before and after the main crop.
- Succession interval: how often a new planting is made.
- Harvest window: when a planting is likely to produce useful crops.
- Review record: what actually happened, including delays, pest pressure, and bed availability.
Keep the plan flexible. A succession that works in a cool spring may need a longer interval during summer heat, while fall plantings may need to be closer together because growth slows as daylight decreases.
What to track
A 12-month planning calendar
Use the calendar below as a starting framework. Replace month names with your local planting windows and add exact dates after checking the season’s weather forecast. In warm climates, the cool-season and warm-season tasks may be reversed or overlap.
| Month | Planning and crop tasks |
|---|---|
| January | Review last year’s notes, order seed, check germination, map beds, and identify crops for early protected sowing. |
| February | Start suitable transplants, prepare trays, test irrigation, and schedule the first cool-season successions. |
| March | Sow hardy crops as conditions allow, plant the first outdoor blocks, and record soil and bed readiness. |
| April | Repeat quick crops, harden transplants, and prepare warm-season beds without planting tender crops too early. |
| May | Plant warm-season crops in stages, add trellises, and note which beds will open after spring crops finish. |
| June | Continue beans, cucumbers, squash, herbs, and greens where suitable; protect young plants from heat and drought. |
| July | Begin fall planning, sow or transplant crops that tolerate late-season conditions, and clear finished crops promptly. |
| August | Make key fall successions, maintain moisture during establishment, and use shade or protection for sensitive seedlings. |
| September | Finish late-season plantings, protect crops from early cold, and consider a cover crop for beds that will rest. |
| October | Harvest storage crops, remove diseased plant material, and record final harvest dates and bed turnover. |
| November | Apply approved soil-building practices, protect bare soil, clean tools, and summarize the season’s successes and gaps. |
| December | Archive the plan, compare expected and actual harvests, and revise crop quantities, intervals, and rotations. |
Succession intervals for 20 common vegetables
These are planning ranges, not guarantees. Use the shorter end when growth is fast and harvest demand is high; use the longer end when weather is cool, labor is limited, or the crop will be harvested at a larger size.
| Crop | Typical succession approach |
|---|---|
| Arugula | Sow every 1–2 weeks while temperatures support good quality. |
| Beans | Plant a new block every 2–3 weeks, stopping early enough for pods to mature before cold weather. |
| Beets | Sow every 2–3 weeks for roots and repeat sowings for greens. |
| Bok choy | Use 2–3 week intervals and favor cool periods to reduce bolting risk. |
| Broccoli | Schedule varieties or transplant batches several weeks apart rather than relying on one planting. |
| Carrots | Sow every 2–4 weeks where soil and moisture can be managed consistently. |
| Cilantro | Resow every 2–3 weeks, especially before plants flower in warm weather. |
| Corn | Plant blocks 1–2 weeks apart if the season is long enough and pollination will remain adequate. |
| Cucumbers | Use a later planting 2–4 weeks after the first to replace declining vines. |
| Green onions | Sow every 2–4 weeks for a continuous supply of small bulbs or scallions. |
| Kale | Plant or sow in spring and again in late summer for fall and cool-weather harvests. |
| Lettuce | Sow or transplant every 1–3 weeks, extending intervals during hot weather. |
| Mustard greens | Repeat every 2–3 weeks in cool conditions; pause if heat causes poor quality. |
| Peas | Make early and later sowings where the season permits; avoid planting into unsuitable heat. |
| Radishes | Sow every 1–2 weeks for small roots, adjusting for heat and soil moisture. |
| Spinach | Repeat every 2–3 weeks in cool weather and shift to a fall schedule in hot regions. |
| Squash | Use a second planting 2–4 weeks later if space and disease pressure allow. |
| Swiss chard | Sow or transplant in spring and late summer, with repeat sowings about every 3–4 weeks. |
| Turnips | Sow every 2–3 weeks for roots and greens, particularly in spring and fall. |
| Zucchini | Stagger a second planting 2–4 weeks after the first to extend production. |
Calculate a practical succession
Estimate the interval from the crop’s expected harvest period, not just its days to maturity. A simple formula is:
Planting interval = desired harvest span ÷ number of planned harvest blocks.
For example, if you want lettuce available across six weeks from three blocks, begin with an interval of about two weeks. Then adjust for weather and your actual harvest rate. If one block is harvested quickly, shorten the next interval; if it remains productive longer than expected, delay the following sowing.
Track the quantity as well as the date. For direct-market production, estimate the number of bunches, heads, or pounds needed per market day. For a home garden, note how much your household uses each week. This prevents a mathematically tidy calendar from creating more produce than you can eat, preserve, or sell.
Cadence and checkpoints
Build the plan in five steps
- List fixed constraints. Mark frost estimates, vacations, market days, water limits, protected growing space, and the date by which beds must be cleared.
- Choose priority crops. Separate reliable staples from trial crops. Plan successions for crops you use regularly or can sell consistently.
- Assign each crop to a bed. Give every planting a bed number, row length, or container location. Include a turnover date and the crop that follows it.
- Schedule sowing and transplanting. Count backward from the desired harvest window. Include time for seedling production, hardening off, and likely weather delays.
- Add review dates. Set a weekly observation, a monthly calendar review, and a seasonal rotation review. A plan that is never compared with field conditions will quickly become inaccurate.
Crop-rotation and bed-rest templates
For a simple four-bed rotation, group crops by plant family and avoid placing the same family in the same bed repeatedly. A workable template is:
| Year | Bed 1 | Bed 2 | Bed 3 | Bed 4 |
|---|---|---|---|---|
| 1 | Legumes: peas or beans | Brassicas: kale or broccoli | Roots: carrots or beets | Fruiting crops: tomatoes or squash |
| 2 | Brassicas | Roots | Fruiting crops | Legumes |
| 3 | Roots | Fruiting crops | Legumes | Brassicas |
| 4 | Fruiting crops | Legumes | Brassicas | Roots |
Within each bed, record the exact family rather than relying on crop names. Tomatoes, peppers, and eggplants belong to the same family; cabbage, kale, and radishes have related disease considerations even though radishes are root crops. If a bed has a serious disease issue, extend the interval before returning a susceptible family and remove affected material according to safe garden practice.
A bed-rest template can read: bed number, previous crop, removal date, pest or disease notes, soil task, cover crop or mulch, next crop, target planting date, and actual planting date. Rest does not have to mean leaving soil bare. A suitable cover crop, living mulch, or finished compost plan can protect the surface while the bed is not carrying a vegetable crop. For more detail, see the guide to cover crops for small farms and gardens.
Protected growing adjustments
A greenhouse or hoop house may allow earlier or later production, but do not simply move every outdoor date by the same number of weeks. Compare nighttime temperatures, soil temperature, ventilation, light levels, and the crop’s tolerance. Start with the outdoor planting date, then test a small protected batch earlier. Record the actual transplant and harvest dates before expanding the schedule. Protected spaces also need their own rotation and disease records.
How to interpret changes
At each review, compare four dates: planned sowing, actual sowing, first harvest, and final useful harvest. The gap between them tells you which part of the plan needs adjustment.
- Late emergence: check soil moisture, temperature, seed age, sowing depth, and seed-to-soil contact before changing the interval.
- Early bolting or poor quality: lengthen intervals during heat, choose a more suitable variety, add shade where appropriate, or move the crop to a cooler part of the season.
- Overlapping harvests: reduce the number of blocks, increase the interval, or choose varieties with different maturity windows.
- Harvest gaps: shorten the interval, add a backup planting, or use a crop with a more predictable maturity period.
- Repeated pest or disease pressure: review family placement, crop removal, airflow, irrigation timing, and the length of the rotation.
Do not revise every date after one unusual week. Look for a repeated pattern across two or more plantings. Weather, variety, soil condition, and management all affect maturity, so change one major assumption at a time when possible. Keep a short note explaining why a date changed; that note is often more valuable than the original calendar.
When to revisit
Revisit the calendar weekly during active planting and harvesting. Confirm that the next succession still fits the available bed, seedling supply, water, and labor. Review it monthly during the main season, especially after a heat wave, prolonged rain, frost, pest outbreak, or major change in household or market demand.
At the end of each season, archive the completed plan and create the next version. Update frost assumptions, protected-growing dates, varieties, pest and disease notes, and the crops that followed one another successfully. Check seed inventory before ordering more, and compare planned quantities with actual use or sales. If you manage a small farm, connect this review to your crop budget and market commitments; the small farm break-even guide can help organize those figures.
To begin now, draw your beds, label them, and enter the next six weeks of plantings. Choose one fast crop and one longer-season crop to track closely. Record every sowing and harvest, then use the results to adjust the following succession. Over time, this simple feedback loop will give you a more dependable continuous harvest calendar than a generic planting chart.
