Try succession planting in your garden to get continual yields and maximize your growing space! In this article, we’ll teach you how to do succession planting in your garden.
What is succession planting?
Before jumping in, we should define what “succession planting” means.
Definition: Succession planting is any method or combination of methods that increases the availability of crop plants in your garden throughout a particular growing season(s).
Succession planting helps you get more food from less space over a longer period of time. Hey, that sounds like a good idea!
So how do you succession plant in your garden?
Succession planting is an approach not a formula
If you’re looking for one perfect succession planting formula to follow, we’ve got some good news and some bad news… The bad news is there’s no single right way to do succession planting.
The good news? You can do lots of experimentation with succession planting since there is no “wrong” formula. The succession planting strategies you employ can vary depending on:
- the season,
- the types of plants you enjoy eating,
- your climate zone and microclimates, and
- a host of other factors.
With some basic plant knowledge, planning, and experience, you can get really good at succession planting.
Succession planting in your fall and winter garden
Since it’s November as we’re writing this article, we’re going to provide some fall & winter succession planting tips that we’ve used successfully in our moderate climate in Ag Zone 7b, just outside of Greenville, South Carolina.
Please steal any ideas we have here, improve on them, and also get creative and try your own!
“Cut and come again” vs “one and done” vs “versatile” veggies
One of the keys to a good succession planting plan is considering how you’ll harvest a particular plant. For instance:
- “Cut and come again” veggies are plants provide multiple harvests over the growing season.
- “One and done” veggies are plants that provide a single harvest.
- “Versatile veggies” are plants that can fall in either category.
Cut And Come Again Veggies
Examples of “cut and come again” veggies that thrive in cool/cold weather include:
- arugula (both annual and perennial varieties)
- Austrian winter pea greens (tender shoots/leaves eaten as salad greens)
- claytonia/miner’s lettuce
- collard greens
- mustard greens
One And Done Veggies
Examples of “one and done” veggies that thrive in cool/cold weather:
- bok choy (technically, you could put bok choy under the “versatile veggies” category in the next section because you can also just harvest a few outside leaves at a time – but we usually harvest the entire plant at once)
- Brussels sprouts
Versatile, cool weather garden plants that can be used as either “cut and come again” or “one and done” garden plants include:
Broccoli – Depending on the variety, many broccoli plants will actually continue forming lots of smaller florets after you’ve harvested the main floret head, not to mention the leaves can be eaten like kale. These are typically sold as “sprouting broccoli.”
Celery – Celery you buy at the grocery store has been harvested as a “one and done” plant. However, you can harvest celery stalks as you need them from the outside of the plant, leaving the plant in the ground to continue growing.
Chicory – There are lots of wonderful varieties of chicory. Some can be harvested as individual leaves over many months (ex. leaf chicory) and some are bred to be harvested as a single head (ex. Belgian endives).
Lettuce – You can harvest enough outside leaves from the heads of a few lettuce plants for a salad without harvesting the whole head. Or you can let it mature to harvest as a large, single head. If you cut the head about an inch above the ground, a new smaller lettuce head will form from the side of the stalk.
Planning Your Garden Succession
Now put your thinking cap on for a minute… What would happen if you planted your entire fall/winter garden at the same time in only “one and done” plants?
Let’s say you planted a monoculture of Brussels sprouts…
- You’d be waiting for a while to get a harvest since most Brussels sprout varieties take 90+ days to reach maturity.
- You wouldn’t have anything to eat from your garden while you were waiting.
- Once you got a harvest, you’d be done and have to start over again.
- You’d get very tired of eating Brussels sprouts.
Polyculture succession planting
What if instead you planted multiple plant species together (polyculture), with:
- some varieties that you could start harvesting within a few weeks,
- some varieties that would give you continual harvests for several months, and
- others that would give you one big delicious harvest all at once?
You’d eliminate problems all four problems listed above. And your soil microbes would be happier too.
So, start your fall/winter garden succession planting plans by using the plant lists above to fill your garden beds with “cut and come again,” “one and done,” and/or “versatile” plants!
Five Considerations For Timing Your Succession Plants
Various aspects of timing should also factor in to your succession planting plan, as outlined below:
1. Direct Sow, Transplant, or Both?
Direct sowing your seeds in the garden is quite easy. Some seeds actually prefer to be direct sown since they’re sensitive to root disturbance/transplant shock (examples: carrots, parsnips, beets, etc).
The downside to direct sowing for other seeds is you might not get optimal germination due to temperature and moisture fluctuations. Plus, direct sowing makes it a little harder to get a jumpstart on the season since you’re not putting in 4-6 week old plants.
Starting your seeds indoors then transplanting them out is a little more time and knowledge-intensive. It’s also best done if you have grow lights (here’s our setup) or a really sunny south-facing window. Otherwise your plants won’t get enough direct light and will get leggy.
Personally, we like to do both direct sowing and transplanting. Transplanting allows us to start some of our fall seeds in late summer, far earlier than we’d be able to if we were direct sowing them all. The same is true when we start our tomatoes, peppers, and eggplants indoors in Feb-March before transplanting them out after our last frost date in April.
2. Succession Sowing
Succession sowing means immediately putting in new seeds once you harvest out a fast maturing plant. For instance, radishes can reach maturity very quickly, in as little as a few weeks, so you can grow a huge number of radishes back to back in the same spot in the cool months.
The best way to ensure a continuous harvest of high quality radishes is to plant 15 per square foot every 5-14 days. Sow them a bit more deeply in order to obtain larger roots — radishes will poke their shoulders above the soil as they grow (which makes it easy to tell when they’re big enough to pick).
They will grow even longer roots if the seeds are planted an inch deep instead of the more common recommendation of ¼ inch deep.
3. Days To Maturity
Every seed variety is different, so check the “days to maturity” on your seed packet. This simply means how many days you should expect it to take between sowing the seed and harvesting the plant.
Also important to note for leafy greens is days until “baby greens” can be harvested, as well as days until full maturity. For leafy greens like kale and arugula, we like to sow them densely, then “thin out” the least vigorous plants to eat as baby greens for salad 3-4 weeks after sowing. We leave the most robust plants to reach full maturity.
4. Seasons & Zones
Related to “days to maturity,” are seasonal and zone considerations. If you live in Maine and you put cabbage seeds (which take 80+ days to mature) in the ground in November, you’re not going to have much success unless you have a heated greenhouse, polytunnels/lowtunnels, or cold frames.
Also, even though you can grow the same varieties of garden veggies in the fall and spring (or winter in warmer zones), factor in that it will take longer for your plants to reach maturity in the fall than in the spring. Why? The days are getting shorter and colder, not longer and warmer.
5. To Cover Or Not To Cover?
If you live in Zones 8 or warmer, there’s a good chance you can garden straight through the winter without covering your plants. If the temps happen to drop into the 20s, you can just put old sheets or blankets over your more cold-sensitive plants. However, gardeners in colder climate zones will benefit from growing more cold-sensitive plants under a polytunnel/lowtunnel or inside a cold frame. Any time it rains or daytime temperatures are over 55°F, uncover the plants so that they don’t get too hot, which will stress them.
Final Note: Should You Let Your Soil Rest?
We’d like to dispel a certain myth that got started back before agronomists knew anything about the soil food web: no, your soil should NOT “rest,” e.g. be left fallow. Ever.
In nature, soil without roots in it is either in a temporarily disrupted state or it’s called a desert (and you’re not trying to grow a desert).
Soil is alive and the microorganisms that feed/protect your plants are kept healthy and diverse through:
a. Growing a diversity of plants whose root exudates feed different species of microorganisms. (This is one reason why polyculture plant systems are much better for soil health than monoculture plant systems.)
b. Not tilling your soil, since tilling disrupts/destroys soil microbial communities, especially fungi.
c. Using brown or green mulches to cover your soil surface. Brown mulch = dead plant material like wood chips, leaves, etc; green mulch = cover crops.
d. Using compost/worm castings 1-2 times per year to make sure you have a good mix of symbiont and predatory microorganisms in your soil. Put 1-2″ of compost on the soil surface before you top-dress with wood chips OR make an actively aerated compost tea soil drench if you already have a thick layer of mulch on the surface. Don’t have any homemade compost or worm castings? Thankfully, you can buy really good ones here.
