Succession Planting: Never Run Out of Fresh Greens

Picture this: you have just harvested the most beautiful head of lettuce from your garden. Crisp, fresh, absolutely perfect. Then you look at the bed and realise that was your last one. The next batch is still tiny seedlings, weeks away from being ready. Sound familiar?

This is the classic feast or famine problem of home gardening, and succession planting is the solution. It is one of the simplest techniques you can learn, and it will completely change how you eat from your garden.

What Is Succession Planting?

Succession planting simply means sowing the same crop at regular intervals instead of all at once. Instead of planting 20 lettuce plants on the same day (and having them all ready at the same time), you plant 5 every two weeks. This way, you have a steady stream of harvest coming through rather than a glut followed by nothing.

It is not a new idea. Market gardeners have been doing this forever. But home gardeners often forget about it in the excitement of planting day when you just want to get everything in the ground at once.

Which Crops Benefit Most?

Not every crop needs succession planting. Tomatoes, for example, produce over a long season from a single planting. But quick-growing crops that have a short harvest window are perfect candidates.

The best crops for succession planting:

• Lettuce and salad greens: The poster child for succession planting. They bolt quickly in warm weather, so staggered plantings keep fresh leaves coming.
• Spinach: Goes to seed fast, especially as temperatures rise. Regular sowings keep you in spinach.
• Spring onions: Ready in about 8 weeks, and once you pull them, they are done. Keep sowing for a constant supply.
• Coriander: Notorious for bolting. Sow every 2 to 3 weeks and you will always have fresh leaves on hand.
• Radishes: Super quick (4 to 6 weeks), so you can squeeze in many rounds.
• Beans: Bush beans especially. They produce for a few weeks then slow down, so staggered plantings extend the season.
• Beetroot: Sow every 3 weeks for a continuous supply of roots and leaves.
• Carrots: They take longer but stagger your sowings by 3 to 4 weeks for an extended harvest.

Timing Between Sowings

Getting the timing right is the key to successful succession planting. Here is a simple guide:

Succession Planting Schedule

The “One In, One Out” Rule

This is the simplest way to think about succession planting. Every time you harvest a crop, replant that spot with the next round. Pulled out your spring onions? Sow more seeds right there. Finished with a row of lettuce? Pop new seedlings in.

This approach works brilliantly because:

• You do not need a complicated calendar
• Your garden stays productive at all times
• You naturally rotate through crops
• It becomes second nature after a few rounds

Planning a Succession Calendar

If you like to plan ahead (and honestly, a little planning goes a long way), here is how to set up a succession calendar:

1. List your must-have crops. What do you eat every week? Lettuce, herbs, spring onions? Start there.
2. Note the sowing interval for each crop from the table above.
3. Count backwards from when you want to eat. If lettuce takes 8 weeks and you want salads all summer, start sowing 8 weeks before summer begins.
4. Block out sowing dates in your calendar or app. Even a simple reminder on your phone works.
5. Adjust for seasons. In summer, you might sow bolt-resistant lettuce varieties. In winter, swap beans for peas.

Replanting After Harvest

When you clear a crop and replant, take a minute to refresh the soil first. This does not need to be a big production:

• Add a handful of compost to the spot
• Lightly fork it through the top layer
• Water the area before sowing or transplanting

This gives your next round of plants a fresh start with good nutrition. Succession planting asks a lot from your soil, so feeding it between rounds keeps everything productive.

Making It Work in Small Spaces

Succession planting is actually perfect for small gardens and balconies. You do not need a huge area. A single pot or a half-metre row is enough for a succession of lettuce or herbs.

Container succession tips:

• Use a large pot (at least 30cm) and sow seeds on one side. Two weeks later, sow on the other side.
• Keep a few small pots rotating through with coriander or spring onions.
• Windowsill herb gardens are perfect for this. Sow a new pot of basil or coriander every couple of weeks.

Common Succession Planting Mistakes

Planting too much at once. The whole point is to plant less, more often. Five lettuce plants every two weeks beats 30 all at once.

Forgetting to sow. Life gets busy. Set a recurring reminder or use an app to nudge you. This is where the habit really matters.

Ignoring the seasons. Succession planting is not about fighting the climate. If it is too hot for spinach, do not keep sowing spinach. Switch to a warm season alternative like kangkong or amaranth.

Not feeding the soil. Your garden bed is working overtime with succession planting. Keep the compost coming.

The Payoff

Once you get into the rhythm of succession planting, something wonderful happens. You stop buying certain things at the shops entirely. There is always a handful of spring onions ready, always fresh lettuce for a salad, always coriander for your stir fry.

It is one of those gardening skills that sounds fancy but is really just about being consistent. Plant a little, wait a bit, plant a little more. Your future self, the one making dinner and ducking out to the garden for fresh greens, will be very grateful.
