Succession Planting and Intercropping Techniques
Growing more food from the same garden space seems like a fantasy to many gardeners. Yet, there are a few highly proven, time-honored techniques which have been tested and refined over the past several centuries which are perfect for today’s gardens.
We will show you two of these techniques in today’s article, giving some examples to get you started. Do not be fooled by the simplicity of these approaches, as they are easy and quick to understand but have many nuances that will only show themselves to you with experimenting and careful observation.
Also, don’t be put off thinking these are too difficult to try or to have initial success with. You will be amazed at the increase from your existing garden bed with a first approach, but realize that a careful and thoughtful study will return much more for years to come.
How Succession Planting Works
Enjoying delicious, freshly picked greens from your garden from mid spring through winter, even after the first frosts and into the harder freezes is entirely possible with just a little planning and understanding. The amazing part is it doesn’t much matter what climate you live in. Most greens thrive in cooler weather, but there are some heat loving varieties which will fill in the hotter months.
Spinach is a fast growing cool season green that only lasts a short time, so it needs to be re-planted every couple of weeks for a continual harvest. This is known as succession planting. Lettuce is another cool season crop that can either be harvested continually for leafy types or must be succession planted for the heading varieties of lettuce.
Large Container Succession Planting
Succession planting involves seeding a short section of a garden bed, letting the crop start to grow then planting the next section a couple of weeks later. This continues down the bed, with the crop maturing in successive waves and giving you a continual harvest. Most gardeners will succession plant only a couple of feet at a time, so as not to overwhelm themselves with too much of a harvest at one time.
Other greens, such as Swiss chard, kale and collard greens grow more slowly and can be harvested all season long – they are both heat and cold tolerant, giving double duty in the garden.
Heat loving greens include amaranth, New Zealand spinach, Huazontle or Red Aztec Spinach and both red and green Malabar spinach, besides the above mentioned types.
Make sure to expand your focus outside of only greens, as there are many other vegetables which will do extremely well in succession planting. One example for a single garden bed or row are a full garden bed planting of early spring peas (which have a harvest season of just a couple weeks) followed by Bok Choi or other Chinese cabbage in a succession pattern, which is then followed by New Zealand spinach going into the warmer weather. This could be extended with fall radishes, beets, Swiss chard or kale if there is enough growing season.
Green onions succeeding summer greens
From this one row, you have gotten three or four different vegetables on an almost continual basis from early spring into very late fall or early winter. If you are able to provide some cold weather protection or season extension for the bed, such as a plastic sheet row cover supported on PVC hoops, you can easily extend that season by a couple of weeks on the spring side and a month on the fall or winter side.
In some climates, just that one simple addition will give you the ability to grow year-round, with spinach, Swiss chard and kale rounding out the slower growing and colder winter.
Another example would be early spring spinach and lettuce, followed by bush snap beans, then fall beets. Or early season carrots can be followed by snap beans during the warmer months with radishes in the fall.
Succession planting on left and intercropping lettuces on right.
These varieties should be planted early – small beets and beet greens, young cabbage, carrots, cauliflower, kohlrabi, lettuce, green onions, peas, radishes, spinach, and turnips; as these are all cool-weather crops. They can be followed by warm-weather crops such as beans, melons, squash and transplants of eggplant, peppers and tomatoes. The warm-weather crops can then be followed by another planting of your favorite cool-weather crops which will mature in the fall.
Any succession can be made that allows crops to reach maturity within the growing season. Swiss chard, Chinese cabbage, collards, corn salad, endive, kale, leeks, lettuce, and mustard are cool-season crops that can follow warm-season crops for late autumn and winter harvest.
What Intercropping Is and How to Use It
Another technique to grow more from the same amount of garden space is called intercropping or interplanting. This makes use of faster maturing varieties planted alongside slower maturing ones. Both are planted at the same time, with the fast growing vegetables being pulled and eaten before they interfere with the slower growing ones. This makes greatly efficient use of a smaller garden space and can double or triple the amount of food grown on the same space.
Quick-maturing crops include: radishes, leaf lettuce, green bunching onions, turnips, and mustard greens. These crops usually mature in 60 days or less from sowing to harvest.
Slower or long-maturing crops include tomatoes, corn, squash, cabbage, eggplant, and peppers. These crops require more than 60 days from sowing until harvest, often 90 days or more.
When planning to intercrop a garden bed, pay particular attention to the days to maturity on the web site and description.
Here is a simple step-by-step guide to succession crop planning:
Intercropping has three main advantages compared to only growing one variety at a time in a garden bed. First, this method allows you to squeeze two, three or more beds of vegetables into one, without detriment. Something as simple as a bed of carrots with a trellis of cucumbers down the middle makes a big difference in the amount of food grown. Learn to think vertically as well as width and length of the garden bed.
The second advantage is with a bit of planning, plants can benefit and protect each other. Even passive protection such as a better microclimate under the plant leaf canopy can deter destructive pests. If you plant varieties of vegetables, herbs and flowers which are actively beneficial to each other, then you’ve just stepped everything up a notch!
The third advantage is a dense plant cover or canopy, creating a more beneficial and stable microclimate for the soil and micro-organisms in it. The moisture levels will be more consistent, needing less amount of water less frequently while keeping temperatures more stable, reducing stresses on the plants and their moisture transport systems.
Intercropping kale and Swiss chard in a container.
A word of caution here – plants do not like to be crowded or spaced too closely together to where they begin to compete for resources such as moisture, nutrients or light. Start small and add one crop to this year’s planned garden bed, not trying to squeeze all four in the first season. Once some experience is gained, then add more and in a year or two the garden bed might look like the following!
In his book “The Winter Harvest Handbook”, Eliot Coleman talks about the French market growers around Paris would sow an early spring hotbed with a mixture of radish and carrot seed by broadcasting the seed by hand. Lettuce seedlings would be immediately transplanted into the bed.
The radishes would mature first and be harvested, giving room for the carrots growing between the lettuces. The carrot tops would grow above the young lettuces until the lettuce matured and were harvested, leaving more room for the carrots. Once the lettuce was harvested, cauliflower starts were transplanted into the bed. Once the carrots were harvested, the cauliflower was alone until it was harvested and the bed made ready for the next set of crops.
Using this example, four crops of significant amounts are harvested from one bed during a single season. The bed wasn’t allowed to be idle after that season either, it had a fresh thick layer of well-aged compost applied and worked in, then it was re-seeded with a different mixture of seeds and transplants. Given this example of cool season crops being planted, the next set was probably warm season varieties such as beans, cucumbers, squash, Swiss chard, melons and bunching onions with transplants of tomatoes, peppers and eggplant.
Fall intercropping – tomatoes finishing with cabbage and Brussels sprouts
With all of these positive, productive examples, there are a couple of things to realize at this point.
One, becoming successful at intensive intercropping and succession planting takes some skill and experience. Gaining that skill and experience requires making some mistakes, learning from them and documenting what was planted when in a Garden Journal for future reference.
While the explanation of intensive planting is easy to understand and we’ve shared a number of successful examples, what will ultimately work in your particular garden depends on several factors which are very possibly quite different than ours.
Two, managing a very intensively planted garden will give abundant yields of vegetables but will require more thought, planning and time in the garden initially during planting and again during the harvest when significantly larger amounts of crops are hitting the kitchen counter and dining room table. There will simply be much more food needing attention than before.
This leads to the need for skills and knowledge in preserving the gardens bounty through freezing, canning, dehydrating, fermenting and pickling. Of course, the consequence of this course of action is having much more food on hand and the inescapable sense of accomplishment when the realization strikes that there are several months’ worth of home-grown, delicious food put away.
Perhaps this is how one garden can change the world! Or maybe it should be one garden at a time…
Alpine strawberries have captivated our taste buds for a very long time. They are tiny yet highly aromatic and hugely flavorful ancestors of our common strawberry. Archeological excavations have shown Stone Age people in Denmark and Switzerland enjoyed them immensely, as shown from the evidence of seeds in those sites.
What we would recognize as alpine strawberries were first domestically cultivated in ancient Persia, where they were considered delicacies fit only for royalty. As often happens, seeds made their way both east and west through trade along the Silk Road route, becoming widely grown and loved.
The Roman poet Virgil named the strawberry in works about country life, associating it with other wild fruits and citing the beauties of the fields in his third Ecologue. During the same period Ovid mentions the mountain strawberry in his description of the Golden Age in book one and again in book thirteen of his Metamorphoses narrative. Pliny is considered the last of the ancients to write of the strawberry, listing “Fraga”, the strawberry fruit, as one of the natural products of Italy in the twenty first book of his Natural History series.
From the 10th century until the early 19th, alpine strawberries were hugely profitable, highly regarded and very well known. After suffering from some mis-informed bad publicity in the mid-1100s, alpine strawberries became quite popular in religious paintings beginning in the late 1300s – often associated with Mary and the Baby Jesus in illuminated manuscripts and paintings. The Catholic Church and royal families from Italy, France, England and Germany were responsible for much of the promotion of the alpine strawberry as they tasted and fell in love with it.
Madonna among the Strawberries – with the carpet of alpine strawberries
A few excellent examples are located in the School of Cologne in Germany. “The Madonna of the Roses”, “The Garden of Paradise” and the “Madonna among the Strawberries” all portray the Madonna as a young girl in a closed garden with the infant Jesus in her lap. She is surrounded by roses, thistles, carnations, lily of the valley, iris, primrose and the entire plants of the alpine strawberry, showing its tiny, prolific red fruit and white five petal flowers along with its toothy leaves. The alpine strawberries are painted botanically correct and are exact, perfect replicas of what we see today. They are always portrayed in a place of honor and importance, reflecting the standing they held in elevated society of the day.
By the late 1300s the alpine strawberry was in widespread cultivation throughout Europe as more of the working classes began transplanting the alpine strawberry from the woods and wilderness to their gardens. Street vendors were selling the fruit to Londoners in 1430 when John Lidgate wrote the song “London Lickpenny” which mentions ripe strawberries and cherries for sale in London.
All strawberries up until the mid-1700s were all of the alpine or wood type; being very small, highly aromatic and having much more flavor than would be thought possible for their size. These characteristics are what made them so remarkable, along with their intense sweetness. Another interesting fact is not all of these strawberries were red; there were white and yellow varieties which were just as highly regarded as the red ones, having different flavors of their own.
This begin to change with the world exploration of the early 1700s, with plant and animal samples brought back to Europe from all over the world.
The modern domesticated large fruited strawberry got its start from these collecting expeditions, with a few strawberry plants brought back from a mapping trip to Chile by Amédée-François Frézier, a French naval engineer who noticed and enjoyed the tremendously large strawberries growing along the Chilean coast in 1712. He wrote the fruit were commonly as large as a walnut; almost three times the size of the alpine strawberry of the day. He brought back plants which were installed in the royal gardens and in Brittany, which grew well but did not set any fruit. It was later discovered the Chilean strawberries have male and female plants, and Frézier had only brought back female plants.
It wasn’t until 30 years later when someone brought back male strawberry plants from Virginia that the Chilean strawberries began to produce fruit, creating the first hybrid strawberry. This new variety is the foundation of all domestic strawberries grown today with the large and familiar heart-shaped fruit.
As would be expected, alpine strawberries began a decline in popularity as their larger sized and heavier producing cousins gained recognition, both in Europe and America.
Alpine strawberries returned to their former, more exclusive roots, being highly valued by pastry and dessert chefs in France and across Europe for their highly concentrated flavors, balanced sweetness and heady aroma that would perfume a room. Eventually, French and Viennese pastry chefs would raise the use of “Fraises des Bois” to a high art form, competing with each other to make the most visually stunning, aromatic and delicious pastries and desserts possible.
Today, alpine strawberries are almost nonexistent in grocery or specialty stores, but are imported from Europe as ingredients in gourmet jams, sauces, liqueurs and as a coloring agent in cosmetics. The best way to experience these flavors and scents – often described as “ambrosia” – for yourself is to grow them in your garden.
While alpine strawberries may not be as productive in weight as their domestic cousins, what they lack in quantity is more than made up for in quality. Given fertile soil, proper conditions and some care, they can be very productive. Enough so that some caterers, confectioners and resorts are buying from local growers specializing in alpine strawberries.
Besides a good quality, fertile and well-drained soil, alpine strawberries need a good amount of sun. In hot areas, they will benefit from partial or afternoon shade. Consistent soil moisture is a key factor in encouraging production, along with a good layer of mulch along their roots to keep them moist. Another benefit is they readily grow true from seed, unlike domestic strawberries which must be started from vegetative propagation.
They don’t send out runners, instead concentrating their energies in flowering and fruiting. They will slowly increase their crowns and gradually grow into mounds about a foot in both diameter and height. They will often flower the first year, but normally won’t set fruit until the second year and will continue producing for several years if well kept. Because of their growth habits, alpine strawberries make for great border plantings as well as edging along a garden walkway or in larger patio containers. They are perennial and can be very cold tolerant if their crowns are heavily mulched to about eight inches before the first hard freeze.
With a little planning and care in planting and tending your plants, you can experience firsthand why mankind has had such an intense love affair with strawberries for so long. You get to taste the same explosion of flavors and be captivated by those intense aromas which Persian kings and European royalty enjoyed so long ago, right there in your home garden.
