Many gardeners in areas that have clay soil (like the Kansas City area) would love to find a way to loosen up the soil, creating more aeration and space for their plants’ roots to grow. A great way to improve your soil is to grow plants that fight compaction in clay soil. Clay soil really holds some of the finest nutrients for growing plants, however the compaction of the soil can make it difficult for plants in your garden to grow.
What is Clay Soil?
Clay soil is comprised of little particles that bond firmly together. These tight bonds (or clumping) can make it challenging for water to be soaked up, or to drain pipes well. If the clay soil is dry, water tends to stream over or through fractures, leaving the primary soil volume dry.
Clay soil can be really challenging to dig up, as it is heavy and clumps together. Clay soil that is largely compressed will make it difficult for the roots of some types of flowers to grow. In addition, if the clay does not drain pipes well and is too damp then particular types of roots will rot.
Recovering Soil with Clay-Busting Plants
If your objective is to bust through the compressed soil, loosening up and aerating it, you will want to inject it with abundant, raw material that your crops will enjoy.
To actually boost your brand-new garden’s success, you’ll want to construct soil life to establish an abundant, regenerative garden ecology.
The good news? Clay-busting plants do all of this work, no back-breaking labor required!
Remarkably, although tilling is a soil loosening technique, it might trigger more damage than excellent by damaging soil life, soil structure, and fungal networks. Learn more about the advantages of a no till garden.
The following list of clay busting plants will help!
Plants That Fight Compaction in Clay Soil: Yearly Clay-Busting Plants
Utilize the list below as a cover that require an increase or a rest. Or interplant them amongst crops to develop garden compost in place.
These clay-busters can likewise serve as soil-healing placeholders in locations slated for seasonal gardens.
All of the following plants are frequently planted in the understory of food forests and fruit tree guilds. Let them self-sow to be semi-permanent wild sources of chop-and-drop mulch. It’s a simple method to create garden compost in place and develop soil without the labor!
While a few of these plants have taproots (likewise called spike roots), others have thick, fibrous roots. When the going is difficult, what they all have in typical is an energetic development practice that continues even.
Partridge Pea (chamaecrista fasciculate)
Having a brief taproot that can punch through clay, Partridge Pea is a dry spell tolerant Native Annual Flower. I’m not overemphasizing when I state that there are actually lots of bees on these plants from sun up to sun down.
Partridge Pea will repair nitrogen from the air to the soil, as it is a bean. This flower makes it’s own fertilizer!
High Sunflower (helianthus giganteus)
Understood as Giant Sunflower, this seasonal sunflower grows really high throughout the season, reaching heights of 8 ′. Direct exposure to wind while growing high will assist reinforce the stalks.
Artichoke (Cynara scolymus)
Artichokes establish deep, tough taproots and are a fantastic mulch plant– both advantages to recovery soil.
The taproots bust through heavy soil, and a reward to planting them is that they’re edible!
Harvest at bud phase, then slice and drop the whole plant in place to make fast mulch and develop soil in place. Leave the roots to decay.
Artichoke is associated with thistle, so keep in mind that the plants are spiny. When managing the plants, I like to use my increased pruning gloves.

Cowpea (Vigna unguiculata)
Like numerous bean types, cowpeas (southern peas) have energetic, thick, fibrous roots that separate clay soil. As nitrogen fixers, they jazz up the soil and enhance.
Plant in the spring as a summer season cover crop. They grow rapidly to reduce weeds, and the flowers bring in useful pests.
To accomplish optimal root development and offer optimal nitrogen material to the soil, cut the plants back while blooming (prior to they set pods).
Can you gather cow peas to consume? Yes, you can collect them as you would green beans or wait up until the pods dry to gather soup beans. An advantage of planting them as a mix cover crop-vegetable crop is that the flowers end up being an insectary for useful bugs.
When grown as a crop, Cowpeas are quickly eliminated by frost. Merely cut them back in the fall to enable the plant matter to disintegrate over the winter season. Bush ranges are simpler to handle.
Mustard (Brassica spp.)
This precursor to our cherished Brassica crops (broccoli, cabbage, kale, and so on) can typically be discovered growing as a weed in locations that have actually ended up being compressed. That’s since it’s a super star clay-busting plant with an enormous, fibrous root system.
It’s a great pointer that nature enables the ideal plants to grow where they’re required.
Mustard is an energetic manufacturer of biomass, so you can grow it as a chop-and-drop green manure/mulch. In addition, it is understood to reduce soil-borne pathogens.
* In the veggie garden, cut mustard back while blooming (prior to it goes to seed), a minimum of 3 weeks prior to planting a spring crop.
Timing is very important
Mustard distributes strongly if permitted to go to seed. It was most likely grown as a forage crop that got away.
Second, mustard can have allelopathic results on the soil while it uses its disease-suppressing action, which is the primary factor for the 3-week hold-up prior to planting a crop.
Integrate plant matter into the soil with a digging fork right away after cutting to benefit from its disease-suppressing advantages. Do not follow mustard with Brassica crops.
The leaves, flowers, and seed are edible, which is why numerous garden enthusiasts permit it to self plant in a food forest or fruit tree guild. Chickens enjoy it, too!
Sunflower (Helianthus anuus)
Sunflowers are an outstanding option for a summer season cover crop.
Search for ranges that do not require staked– they’ll develop energetic roots deep into compressed soil. I like the range soraya.
Sunflowers are an excellent insectary, bring in numerous ranges of bugs. They can likewise supply forage for chickens. And do not forget to conserve a couple of stems for a cut flower arrangement!
In late winter season, cut the plants back however leave the roots to improve the soil and break down. Sunflower roots are understood to have an allelopathic impact on the soil, permitting them to disintegrate over the winter season ought to avoid this from being an issue for spring planting.

Soil Amendments for Clay
Amongst my favorites are biochar, greensand, and worm castings for improving the soil once the clay-busting plants have actually loosened up and aerated it. Required more pointers?
