What is succession planting? It is a way of staggering sowings and transplants so that a bed produces across a season instead of all at once. The University of Vermont Extension defines it as “a technique where you stagger plantings of either the same plant or different plants throughout the growing season.” The Maryland and West Virginia extension pages describe the same idea, and this guide sets out their methods, the timing rules they give, and the sample plans they publish.
Quick answer
- Succession planting means staggering plantings of one crop, different crops, or varieties with different maturity dates in the same space.
- Quick crops such as radishes and lettuce are generally planted at two-week intervals.
- Plan from days to maturity and the harvest season, then match each crop to the season where it grows best.
- Replace a finished crop with a different one as soon as the space is free, and use transplants to save weeks.
The basic idea
The University of Maryland Extension page starts from the purpose: “Succession planting is an important tool to maximize food production: planting seeds or transplants in spots vacated by spent plants.” It explains that a steady supply of greens, beans and cucumbers takes more than one planting, because “Achieving a continuous harvest of leafy greens, beans, cucumbers, and other crops requires planting several small groups of a given vegetable over a period of time.”
The West Virginia page starts from a common mistake. It says “Most gardeners believe succession planting means after one crop is harvested, another is planted.” That is one form of the practice, but the same page lists two more, so the idea is wider than replanting a bed after a harvest. Vermont adds that the method works in any setting: it “can be done in any sized space, such as containers, raised beds or in-ground gardens.”
Three ways to stagger a garden
West Virginia gives the three methods that most growers use. The first is repeat sowing, and the page calls it “The easiest and most common method”: “several smaller plantings of the same crop at timed intervals, rather than all at once.” The second is varieties with different maturity dates. The page says this type “allows you to choose vegetable varieties with different maturity dates.” The third is replacement: “harvesting a crop that has matured and replacing it with a completely different crop.”
Vermont describes a fourth form. It says “Another form of succession planting is interweaving two types of plants that share the same space but reach maturity at different times.” Its example is a row of cilantro in a raised bed that also holds onions, where the cilantro is ready to pick while the onions are still small. The Maryland page uses a related term, “Relay planting”, for repeating one crop. Its definition is short: “Relay planting is the successive planting of one type of crop.”
Days to maturity sets the schedule
Every method depends on how long a crop takes to mature. West Virginia says “Paying close attention to days until maturity is an important part of succession planting.” It gives examples: “Certain varieties of radishes and spinach may mature in 35 days, while many varieties of beans and summer squash may mature in 50 days.” Its cole-crop figure is longer: “Cole crops, such as cabbage, cauliflower and Brussels sprouts, need at least 75 days until harvest.”
Vermont gives the planning steps. It says “By planning out your plantings based on harvest time, preferred season and days to maturity, you can plant more crops throughout the year.” It also suggests a simple sheet: list the plants, add a column for the harvest season, and add a column for days to maturity. It notes that “You can find this information on seed packets, through online cooperative extension resources or on seed company websites.” It adds that “Using a digital spreadsheet could make this easier, as you can quickly sort each category after recording the information.”
The figures above turn into a rough schedule with simple division. The pages do not give a season length, so the table assumes a 105-day window for one bed. That number is our assumption, not a source figure. The last column is the number of full cycles a crop can finish in that window.
| Crop (source figure) | Days to maturity | Full cycles in 105 days (our arithmetic) |
|---|---|---|
| Radishes or spinach, at the early end | 35 | 105 divided by 35 is 3 |
| Beans or summer squash, many varieties | 50 | 105 divided by 50 is 2, with 5 days left |
| Cole crops such as cabbage | 75 | 105 divided by 75 is 1, with 30 days left |
The table shows why crop choice matters for a bed’s schedule. A 35-day crop can be sown three times in the window that a 75-day crop fills once.
Two-week intervals and the planting window
The timing rule that appears most often is the two-week interval. West Virginia says “Quick maturing vegetables, such as radishes, lettuce and other salad greens, are common crops for this technique and are generally planted at two-week intervals.” Maryland uses the same rhythm for beans: “green beans may be planted at two-week intervals for a continuous harvest.” Its general plan is to “plant a portion of that space every two weeks” once the total space for a crop is known.
Early plantings are slower. Maryland says “Early crops are likely to get a slower start due to low temperatures, with later crops growing and maturing more quickly.” That difference means a planting made in cold soil may not match the next one made a few weeks later. Maryland also warns about the result of a good plan: “This often results in a glut of produce at the height of the season, so be prepared to process your harvest in advance.”
Matching crops to the seasons
Crops that handle cool weather and crops that need warmth should not share a slot at the wrong time. Vermont says “Certain crops, including lettuce and peas, are considered cool crops and grow only in the cooler temperatures of spring or fall.” It contrasts them with warm-season crops: “Others prefer the warmer soil and air temperatures of summer, such as cucumbers and corn.”
West Virginia matches the groups to specific crops. It says “Cool-season crops, like radishes, lettuces, peas and spinach, do best in cooler soils.” It also says “Warm-season crops, like tomatoes, eggplant, melons and beans, are more sensitive to frost and grow more slowly in cooler temperatures.” The Maryland page describes the common order of a season: “Cool-season crops (broccoli, lettuce, peas) are followed by warm-season crops (beans, tomatoes, peppers), which are followed by more cool-season plants, or a winter cover crop.”
Maryland gives one planting rule for a crop that is ending: “Plant squash, bean, and cucumber plants when you are finished harvesting earlier cool-weather crops.” It also notes that some cool crops can be sown again later. “Starting in late July, you can also sow seeds of the same crops you direct-seeded in early spring, like beets or mustard greens.”
Sample plans from one university
The Maryland page includes five sample plans. It says “The following sample planting plans can be used simultaneously in vegetable gardens with multiple planting beds.” The plans below are copied from that page, with the dates and crops as listed. The page does not give a location or a frost date for the plans, so the dates should be read as a pattern, not a calendar.
| Bed | Planting date | Crop |
|---|---|---|
| 1 | November 1 | Garlic |
| 1 | July 1 | Cucumber |
| 1 | September 20 | Cover crop: oats and clover |
| 2 | March 1 | Peas and fava beans |
| 2 | June 1 | Summer squash |
| 2 | September 1 | Kale |
| 3 | March 20 | Lettuce |
| 3 | May 15 | Green beans |
| 3 | August 1 | Broccoli |
| 4 | March 1 | Radish |
| 4 | April 15 | Leafy greens (lettuce, spinach, arugula, mustard, kale, mizuna, tatsoi, bok choy) |
| 4 | June 1 | Eggplant |
| 4 | September 15 | Cover crop: rye |
| 5 | May 1 | Cucumber |
| 5 | July 15 | Green beans |
| 5 | September 20 | Spinach |
Bed 3 shows the pattern in one line: a cool crop first, a warm crop next, and a cool crop again after the warm one is done. Bed 4 adds a cover crop in the fall. For vegetables that pair well inside one bed, see our page on vegetables that grow well together in raised beds.
Tips for a successful succession
Maryland gives the practical starting points. It says “Start seeds indoors or in a protected outdoor area.” It also advises “Use transplants, even for crops that are usually direct-seeded”, because “You will gain several weeks of growing time by having transplants ready to go into vacated areas.” The page explains the reason for the advice: “Direct-sowing will make it difficult for the seedlings to get established due to competition with the established plants.”
Vermont offers an encouraging note for gardeners whose beds are already planted. It says “If you’ve already finished planting your garden, you may need to wait until next year to fully try succession planting.” It then adds: “However, you can still try it with crops such as lettuces or greens this summer.” That is the easiest route for a first season.
West Virginia notes that variety choice matters. “Short-season varieties can allow you to harvest a crop and replace it with another quickly.” It also says “It is crucial to do your homework with variety selection.”
Planning on paper
Maryland recommends drawing the plan. It says to “List the crops you plan to grow on paper and draw a map that shows the spacing and location of each crop.” It suggests a separate map for each season, which turns a single plan into several rounds of planting. The page also describes the timing trick that makes a map useful: “Key to planning is understanding how long a plant will be producing a harvest.”
Crop families and rotation
Succession planting is not the same as rotation, but the two are linked. Maryland says “Crop succession is closely related to the concept of crop rotation” and defines the second idea: “Crop rotation is the practice of moving crop families to different garden locations each growing season.” It gives three families as examples: “the tomato/eggplant family (nightshades, Solanaceae), pea/bean family (legumes, Fabaceae), and squash/melon family (gourds, Cucurbitaceae).”
Examples from the pages
Vermont uses sugar snap peas as its first example. It says “sugar snap peas are cool-season plants and tend to be sensitive to heat”, and that “These can be planted in early spring and harvested about 60 days later.” The space they leave can take cucumbers, which “can reach maturity in about 50 days.”
West Virginia gives a sweet corn example. Instead of one planting, it recommends three varieties with different maturity dates, so the harvest is spread out. The page says “you can harvest sweet corn over a period of several weeks.” The method works for any crop with varieties that differ in maturity, which is why the variety list on the seed packet is worth reading.
Vermont also says lettuces are an easy crop to succession plant, and that “Seed companies often have charts that suggest how often to plant certain crops to maintain a continuous supply.” For a short list of vegetables that suit raised beds, see our page on vegetables to plant in raised beds.
How we chose
We chose the three university and extension pages that set out the method in detail: the University of Maryland Extension, the University of Vermont Extension and West Virginia University Extension. We opened each on 2026-10-22 and read the text in full before quoting. We kept the claims that each page states in its own words, and we copied each quoted sentence from the fetched text. A Cornell Cooperative Extension article returned a 403 status, so it is not counted. A second Maryland address that returns the same article is also not counted as a separate source.
What we could not verify
The three pages describe the method well, but they do not give regional planting dates, so the plans above cannot be turned into a calendar for any one area. The Maryland sample plans do not name a location, and the West Virginia figures come from variety descriptions rather than a local trial. The table in this guide uses an assumed window of 105 days, and that figure is ours, not a source figure.
What the sources do not say
The pages do not give a yield per planting or the number of plantings a bed can take in a season. They also do not give a rule for how long a crop family should wait before returning to the same bed, and they do not say how much a two-week interval changes the harvest for each crop.
Frequently asked questions
What is the difference between succession planting and relay planting?
Relay planting is one kind of succession planting. Maryland defines it as “the successive planting of one type of crop”, such as green beans sown every two weeks. Succession planting is wider, because it also covers replacing a finished crop with a different one and interweaving crops with different maturity dates.
How often should I sow lettuce or radishes in succession?
West Virginia says quick crops such as radishes and lettuce are “generally planted at two-week intervals.” Maryland uses the same two-week rhythm for beans. The sources do not give a different interval for each variety, so the best approach is to start with two weeks and watch how the first planting matures.
Can I use succession planting in containers?
Yes, according to Vermont. It says the method “can be done in any sized space, such as containers, raised beds or in-ground gardens.” The same logic applies in a pot: stagger sowings, match the days to maturity, and replace each finished crop.
What should I do if my first planting finishes early?
Replace it with another crop as soon as the space is free. West Virginia describes this as the third method, and Vermont suggests that gardeners who have already planted the season can still try it with greens or lettuce “this summer.” Warm-season plantings are best started once the danger of frost has passed, as Maryland advises.
How do I know which crops can follow each other?
Match the seasons first. Maryland gives the common order of cool crops, then warm crops, then cool crops again or a cover crop. West Virginia notes that “Short-season varieties can allow you to harvest a crop and replace it with another quickly.” Check the days to maturity of both crops before you plan the swap.
