How to Use Cover Crops in Cannabis Cultivation

How to use cover crops in cannabis cultivation

If you’re considering growing cannabis, you may be interested in learning more about the benefits of planting cover crops to help keep your soil healthy. Cover crops can be planted as a way to protect your plants from predators and fungi, as well as improve the quality of your soil. Some of the most popular cover crops include buckwheat, barley, ryegrass, clover, and mustard. These plants all offer various benefits when planted in your garden.


Using cover crops for cannabis cultivation can help keep weeds and pests away. It can also provide a healthy, living environment for the plants you want to grow. You’ll want to choose the right crops, however, since each type works differently.

One type of plant that is a good choice for a cover crop is buckwheat. Buckwheat grows rapidly and attracts pollinators with its abundant flowers.

Another good option is ryegrass. The roots of ryegrass stretch deep into the soil and create a thick matrix that retains water and nutrients.

Depending on the climate, you may need to plant a cover crop in the fall. In the tropics, you can plant brassicas to improve water retention. Brassicas produce mildly toxic compounds and have long taproots.

Using a cover crop can also keep your cannabis garden afloat during the winter. Some cover crops are great for preventing soil erosion, and others fight soil-borne diseases.

Clover is a good choice for a cannabis cover crop because it’s a nitrogen fixer. Nitrogen is a nutrient that the plant needs to produce new green plant matter. If you aren’t using a nitrogen-fixing cover crop, you’ll have to wait until spring to get the benefits of this nutrient.

Hairy vetch is another good choice for a cover crop. Besides the obvious nitrogen fixation, it helps keep your garden healthy after harvest.


Buckwheat is an important cereal plant. It has been cultivated in China for thousands of years. In fact, the earliest buckwheat seed fossils are found in the Chunqiu dynasty (around 2500 years ago).

There are two cultivated species of buckwheat. The seeds are usually planted in the spring or summer.

It can be used to reduce soil erosion, suppress weeds, and improve soil. Some cover crops are excellent at providing nitrogen to the soil and deterring weeds.

These types of crops are a great way to keep your soil healthy and pest-free. They also help reduce nutrient runoff. However, they can be expensive. So, you want to pick the right cover crop to match your particular cannabis production needs.

If you’re in the market for a new cannabis cover crop, buckwheat is a good choice. It has a fast growth rate and produces large volumes of organic matter. As a result, it can boost the productivity of other legumes. This is a great way to keep your soil healthy, and it’s a cheap alternative to fertilizer.

Buckwheat is a member of the Polygonaceae family. The family includes 19 wild species, as well as two cultivated species.

The genus Fagopyrum consists of 21 species. Two cultivated species are the red oat and the tartary buckwheat.

Red oat is a good weed suppressor, but it doesn’t produce much dry matter. Tartary buckwheat, on the other hand, produced the highest shoot and root dry matter.


Using a cover crop in cannabis cultivation can reduce your costs and improve the health of your soil. These crops can also help you fend off predatory bugs and weeds. They can also boost biodiversity and increase microbial activity.

Legumes like oats, rye, and clover can be a good choice for a cover crop. Their roots can absorb nitrogen from the air, thereby improving your soil’s overall fertility. The roots also contribute to improved soil structure and aeration.

Grasse cover crops have extensive root systems that help dramatically reduce erosion. In addition, they produce significant amounts of biomass. This biomass can be returned to the soil and decompose to release nutrients.

Cover crops can be planted as an offseason addition to your crops. A diverse mixture of cover crop species is recommended for the best results.

Some other crops you may consider growing as a cover crop include oats, buckwheat, and mustard. Each of these has unique properties. You’ll want to choose a plant that grows well in your area.

For the best results, a cover crop should be fast-growing. It should also produce plenty of leaf matter. Planting the right seed at the right depth is also important.

Ryegrass is not a good choice for growing in poor soils. Besides, it’s not as winter-hardy as cereal rye. However, it can be used as a fall cover in the Northern Hemisphere.

Mustard is a member of the Brassicaceae family. It has yellow and gold hues and grows to 5-6 feet tall. However, it can be grown much smaller, so it can be a useful plant to use as a cover crop.

When used as a cover crop, mustard helps keep weeds at bay. Since the plant is a legume, it can recycle nitrogen. If left in the soil, it can also suppress nematodes. The plant also attracts beneficial insects, including pollinators.

This herb has also been used as a spice for centuries. Some people believe that mustard seeds are derived from ancient Egypt. In the early twentieth century, people called each other “mustard”.

For cannabis growers, it is best to avoid planting mustard as a cover crop. Instead, plant the buckwheat. Buckwheat is a fast growing legume, so it works well to suppress weeds in your garden.

While mustard seeds can be planted on their own, it is much easier to incorporate them into your garden’s organic fertilizer. You can also press them to make mustard oil.

Although not as well known as oats, mustard has a variety of uses. One is to be eaten as a green. Interestingly, it is also a good source of biofuel.

If you’re looking to add more diversity to your cannabis farm, try using cover crops. They improve soil and reduce environmental damage. By fending off predatory insects, they can also help keep weeds at bay.


If you’re growing cannabis indoors or outdoors, you’ll likely be tempted to use a barley cover crop. Barley is a great way to add nutrients and improve your soil. As it breaks down, it will help your plants grow healthier.

Some cover crops are nitrogen-fixers, which means they can help your plant get the nutrients it needs. Nitrogen is an essential nutrient for plants. It’s important to get enough of it because it helps your plant produce new green plant matter.

Using a barley cover crop can reduce your overall costs, including the cost of fertilizer. It can also reduce your water usage.

Barley straw is breathable and will allow you to water your plant without losing moisture. Additionally, the straw is very biodegradable. This means that it’s ideal for composting. In addition, the straw will enhance your soil by allowing your irrigation water to pass through it.

Cover crops are an easy and efficient way to add some extra nutrients and improve your soil. Aside from the obvious benevolence of using a barley cover crop, it can also be a good way to attract beneficial insects to your garden.

Aside from helping you save money, a cover crop can also boost your overall crop production. They’re usually planted after harvest, but you can also deploy them in between plantings.

Aside from the fact that you’re getting some much-needed nutrients for your marijuana plants, a cover crop is a good way to keep your cannabis from being choked out by predatory bugs. Depending on your climate, you may need to burp your soil more often.


Oats can be used as a cover crop in many applications. They are inexpensive, easy to incorporate, and can provide an effective mulch. Planting oats after other crops can help reduce the amount of added nutrients.

Cover crops are an important part of a living soil system. They enhance the health of the soil, improve aeration, and increase water retention. They also protect the soil from erosion. A cover crop can be deployed during the off season.

Oats are an excellent, low cost fall cover crop. They also work well in the spring. Several benefits of oats include aeration, weed control, and a mat of organic matter to keep the soil from eroding.

Oats can be aerially or drilled. They should be planted at a rate of six to eight inches deep. In areas where the temperature is usually below -15C, oats are not as cold tolerant as other cereal grains.

Various oat cultivars have been developed in response to new pathogens. These varieties have shown minor improvements over older varieties. The ‘California Red’ oat is standard for hay production.

‘California Red’ has a fine root system and shows very fine growth. It has a high crude protein content.

Oats have been widely used as a cover crop for decades. In addition to improving the soil, oats can provide forage for livestock. Their rapid growth and ability to suppress weeds make them an ideal cover crop.
