Relay Planting Calendar

Relay planting tucks the next crop in before the current one is done, so the bed never sits empty. The overlap is the whole trick, and timing it takes care.

Key points

  • Relay planting starts the next crop before the first is finished.
  • Keep the overlap short so the young crop is not shaded or starved.
  • Transplants often handle the overlap better than seed.
  • Record both crops and their families on your calendar.

What is relay planting?

In relay planting, the second crop is sown or transplanted into the same bed while the first is still growing but nearing the end of its life. The two crops share the space for a short overlap, and then the first is harvested and the second takes over.

This differs from simple succession, where the second crop waits until the first is gone. Relay planting gains days, which matters most in short-season areas.

Relay planting is common among market growers and home gardeners who want to squeeze extra production from limited space, and it also works well alongside other methods.

Why use it?

The main reason is time. In places with a short frost-free season, waiting for a bed to clear can use up weeks you do not have. A relay places the next crop at the right moment. It also keeps soil covered, which reduces weeds and erosion.

It takes attention. The older crop competes with the younger one for light, water and nutrients during the overlap, so the plan has to keep the overlap short.

Make a note of which crops handle shade as seedlings. Lettuce and other greens often tolerate light shade, while fruiting crops need more light from the start.

What are examples of good relay pairs?

Choose pairs where the first crop is on its way out and will not shade or crowd the young plants heavily. A tall crop that is finishing may give light shade to seedlings that appreciate it in hot weather.

Treat the ideas below as starting points, since your climate and varieties change what works.

How do you time the overlap?

Work from the second crop's needs. Count backward from your first fall frost for fall crops, or forward from your last spring frost for early ones, and place the relay at the point where the second crop needs to start. Then check that the first crop will be done or cleared soon enough.

For example, if your last spring frost usually falls in the middle of April, peas might be sown as soon as soil is workable, and warm-season transplants might be set between the rows after frost danger has passed and soil has warmed. That is a method, not a date for your garden.

Check the days to maturity on both crops and write both on the chart. If the sum is longer than your season, the relay will not finish and you should pick a faster crop.

How do you protect the young crop during the overlap?

Seedlings under a mature crop can dry out and get shaded. Water the young plants directly, and consider using transplants rather than seed, since they are better able to handle competition. Remove the first crop promptly, cutting at the base if pulling would disturb roots.

Keep an eye on pests and disease. Dense overlapping foliage holds humidity and can encourage leaf diseases, so allow airflow and remove diseased plants. For treatment questions ask extension, and follow every label.

What goes wrong with relay planting?

Common errors are overlapping too long, so the young crop is stunted, and picking pairs from the same family, which lets pests move across. Another is forgetting that the first crop's harvest may trample new plants, so leave a path.

If a relay fails, note why and adjust. Move the second planting later, use bigger transplants, or choose a different pair.

How do you record relay plantings?

On your calendar, draw the first crop as a bar and the second crop as an overlapping bar. Mark the overlap period in a different color. At the end of the season, check whether the second crop reached harvest before frost or heat stopped it.

This record is also your rotation record, so note plant families on the bar chart.

A color-coded bar chart on a single sheet of paper does this job well, and it can double as your rotation record for the following year.

When to get local help: A county extension agent can suggest relay pairs that suit your growing season and local pests.
