While certain companion planting traditions have been passed down through centuries, the origins of others are difficult to trace.

Companion Gardening

This is a review of several ways to companion planting, as well as specific examples supported by research.

Explanation of Companion Planting

Gardeners understand that a wide plant mix, ranging from annuals and perennials to flowers and vegetables, results in a healthier garden. But did you know that the perfect (or wrong) combination of particular plants can really increase (or decrease) their productivity?

This is referred to as companion planting. Growing certain plants in close proximity to others is thought to help discourage pests, boost development, and even improve flavor—or, on the other hand, certain plants, when planted next to one another, may actually inhibit each other's growth.

What are Companion Plants?

Companion plants are plants that grow and produce in tandem with one another. For example, one plant may attract an insect that protects a neighboring plant. Another plant could act as a repellant for a bug that could harm the plant next to it.

It is also critical to consider the nutrients that individual plants require. A companion plant may require less of one nutrient while its neighbor requires it to grow. Companion planting would eliminate the competition between the two plants in this situation.

Benefits of Companion Planting

Companion planting has numerous advantages. Most gardeners would agree that the more assistance you can receive in order to have a profitable, prosperous garden, the better!

What and how can companion planting help?

Companion Planting Can Decrease Pest Issues.

Pests will find it more difficult to harm your crops if you abandon the traditional monoculture garden arrangement. They won't be able to find a consistent supply of their preferred meal. Certain plants can even discourage pests. Wormwood, for example, can be planted among cabbage and other brassicas to help repel cabbage moths, and marigold can be put alongside beans to help deter Mexican bean beetles.

Companion Planting Can Help With It Keeps Weeds Out.

The same way that plant-covered soil holds water, it also prevents weed growth. Vining squash is grown beneath corn and beans in the well-known Native American method, the Three Sisters Garden, to shade the soil and prevent weeds from sprouting.

Companion Planting Can Help With Natural Supports

Tall and robust plants and blooms will provide as natural, organic supports for crops that grow low or sprawl. Planting tall sunflowers next to cucumbers or snap peas is an example of this. The taller plants can be used as a trellis for the sprawling crops.

Companion Planting Can Help With Plant Health

Growing plants near to their companions can benefit both plants' overall health. By removing rivalry between plants, you allow one to absorb what it requires while without depriving the other. Furthermore, as nutrients are drawn from the soil by one plant, the resulting biochemistry of the soil might be altered. When done correctly, the soil can alter or improve the flavor of other plants in the vicinity.

Companion Planting Can Help With Disease Issues.

Disease spreads more quickly across your garden when plants of the same variety are all in one large group, just like it does in crowded crowds. Including several species in a planting can help break up your garden and reduce disease transmission.

Plant interactions, as previously said, are not entirely understood, although certain plants have been demonstrated to make other plants healthier, lessening their susceptibility to disease. Beans in the Three Sisters Garden system provide nitrogen for the corn and squash, and many people feel that growing basil with tomatoes results in healthier tomato plants.

Companion Planting Can Help With Optimize Soil

The root system of a plant can quickly change the soil in which it grows. Plants with lengthy taproots, such as parsnips and carrots, will draw nutrients from the soil's depths. Those plants with short root systems will benefit from the nutrients. Many plants require nitrogen, and some, such as peas and beans, actually help to suck nitrogen in, making it more available in the soil for the plants that require it.

Importance of Soil Preparation for Companion Planting

Companion planting has numerous advantages. It should be noted that companion planting does not take the place of adequate garden preparation and upkeep. Any successful garden benefits from regular watering, occasional feeding, adequate sunshine, and nutrient-rich soil.

Remember that healthy soil implies healthy roots for your plants, so take the time to amend your garden soil before planting your companion garden to give it the best start possible. To produce an optimal growing environment in your garden, combine sand, peat moss, and manure compost.

As a result, the ideal strategy to prepare soil for planting is to add organic matter in the form of compost and aged manure, or to use mulch or to produce cover crops (green manures). Adding artificial fertilizers will only replenish some nutrients and will have no effect on keeping excellent, friable soil.

Examples of Companion Planting

The concept of companion planting, or the planting of specified plant pairings for mutual benefit. "Theory behind companion planting is that certain plants may help each other take up nutrients, improve pest management, or attract pollinators," explains Xaxa gardening Manager.

Consider making your yard more welcoming to some other companions by putting flowers that attract hummingbirds or blooms that attract butterflies while building your companion garden.

Include the best plants for kids or even a whimsical fairy garden to make the space interesting to the younger members of your family. Garden fence designs can add both aesthetic and functional structure to your garden.

Don't forget to make room for some of the loveliest summer blooms. However, set aside some space in your garden, whether it's a small plot or a raised bed, to experiment with these common-sense partner choices. Then relax and reap the rewards.

Three Sisters Companion Planting (Corn, Beans, and Squash)

Since the dawn of plant domestication, several indigenous communities in North America have used companion planting to maximize crop development.

The Three Sisters, or maize (Zea mays), beans (such as Phaseolus vulgaris), and squash (Cucurbita pepo), were the primary companion planting techniques. These three plants collaborate in a magnificent symbiotic relationship to develop stronger than they could individually, with each individual aiding the growth of the other two.

Bean and maize seeds are planted in little mounds of earth, with squash seeds interspersed. The maize grows tall, providing a framework for the beans to climb. In exchange, the bean plants' tendrils wrap around the maize stem, protecting it from wind harm. Beans also contribute to nitrogen fixation by capturing nitrogen in the air and transferring it to the soil in a form that plants can utilize.

The squash tend to the soil for the other plants on the ground. Their broad leaves cover the ground, keeping it from drying out and avoiding the spread of undesirable weeds. Certain squash types feature spiky leaves that dissuade potential grazers like deer and squirrels from eating the crops.

Some North American tribes also grow flowering crops, such as sunflowers (Helianthus anuum), at the boundaries of their fields to attract pollinators and form a natural boundary fence.

The Three Sisters is an excellent illustration of how companion planting can benefit crops, but it is by no means the only one.

This might sometimes happen as a pleasant accident. Clover, commonly seen as an invasive weed, is actually a member of the legume family. This means that, like the beans in the Three Sisters, they can fix nitrogen into the earth. Many grass crops, such as rice and wheat, may then exploit this fixed nitrogen to grow stronger and more nutritiously.

Other companion planting tactics include keeping pests away from your fruits and vegetables. Carrot and onion are a well-known crop combo because their odors protect each other from potential predators. Companion Chart can be found HERE.

Tomato and Basil Companion Planting

Tomato and basil plants are also excellent garden companions. Indeed, when it comes to companion planting, the two are outstanding instances of ideal growing companions.

Companion planting is all about capitalizing on the mutually beneficial ties that exist between two or more plants. In some circumstances, one plant may assist in repelling pests from another.

In terms of insect repellency, basil is a close second to marigolds. It repels whiteflies, aphids, and tomato hookworm extremely well. All three of these factors can be detrimental to the health of a tomato plant.

However, basil repels mosquitoes. When working in the garden, the mosquito advantage is enormous, but you can also harvest some basil throughout the year and arrange it in a vase to help keep troublesome biting insects off porches and patios. As if that wasn't enough, basil also repels houseflies.

So, do tomatoes aid in the growth of basil?

The quick answer is yes.

The broad, lush foliage of tomato plants provides an ideal setting for basil growth. Basil needs moist soil, and the canopy of tomato leaves keeps moisture from evaporating in the scorching summer sun.

The basil grows, and so do the tomato plants!

Marigold and Vegetable Companion Planting

Marigold (Tagetes sp.) is a plant native to South and Central America that belongs to the Asteraceae family.

Marigolds are a fantastic illustration of this. The strong odor of marigold foliage and blooms repels a wide range of pests. They can also help to protect vegetable plants and other flowers when planted around them.

Similarly, all Marigold cultivars act as excellent garden defenders and improve soil quality.

Marigolds are not only beautiful in the flower garden, but they are also beneficial in vegetable patches.

They attract pollinators, protect your veggies from pests and illnesses, and improve soil quality.

However, some vegetables, such as beans and cabbage, are poor Marigold companion plants!

How Companion Planting Works

Companion planting is the near planting of different species based on their capacity to improve one another's growth or provide insect protection or other benefits.

Companion planting can be accomplished in numerous ways:

Types of Plant Companion Interactions

Before you even consider companion planting in your garden, be sure you follow crop rotation rules.

Planting the same garden crop in the same location for consecutive gardening years might result in pest and disease problems as well as nutrient imbalances.

Companion Planting to Repel Pests and Attract Beneficial Insects

Marigolds are one of the most often advertised insect repellent companion plants, but do they work? Yes and no at different times.

Companion plants aid with insect management in three ways:

Using Smells

Plants can create scents that repel or attract insects, or just conceal the odors of other plants.

Because of these characteristics, plants can be used to attract pests away from other crops (trap crops), or to repel them away from the area (repellent crops).

Reduce the likelihood of insects landing on your garden produce since there are too many signals to understand.

By Attracting Predators or Parasitoids

Predator insects consume other insects, while parasitoids lay their eggs within other insects.

You may invite these insects to your garden to help you manage pests by providing habitat and food for them.

By Being Visually Distracting

Some insects employ visual clues, such as leaf shape or color, to locate their prey plants.

Insects may be more attracted to a plot full of the same plant than to a range of plants with varying heights, colors, and textures.

In a nutshell, Companion planting is a time-honored practice that is today more vital than ever.

While many of these solutions are only applicable on a small scale, the principles can teach us how to feed the globe by collaborating with nature.

You may apply your companion planting skills to any garden method. Container gardening, backyard gardens, and raised beds are all excellent places to put this concept into action. The more you understand about what goes well together, the more enjoyable it will be to strive to get the most out of your garden.

All we have to remember is that companion plants, like us, are stronger together.

FAQ

Can you plant any two plants together, or do they need to be specifically chosen for companion planting?

It's not advisable to plant any two plants together randomly without considering their compatibility as some plant combinations may not thrive together. Companion planting is the practice of planting certain plants together to enhance each other's growth and repel pests or diseases. For instance, some plants can help deter pests from attacking their companion plants. Others can enhance soil nutrients and improve soil quality. However, some plants may have negative effects on each other, such as competing for nutrients or being susceptible to the same pests or diseases. Therefore, it's essential to choose plants for companion planting based on their compatibility and beneficial qualities. This practice can lead to a more robust and productive garden.

How far apart should companion plants be planted from each other?

The spacing between companion plants largely depends on the specific plants being grown, as each plant has different requirements for spacing and nutrient needs. However, as a general rule of thumb, companion plants should be planted close enough to benefit from each other's presence, but far enough apart to avoid competing for resources. For example, a common companion planting combination is tomatoes and basil, where the basil is planted closely around the base of the tomato plant. In this case, the spacing between the tomato plants should be at least 18-24 inches apart, while the basil can be planted within 6-12 inches of the tomato plant. It's important to research the specific companion planting combinations you plan to use and follow the recommended spacing guidelines for each plant to ensure optimal growth and yield

Are there any plants that should not be planted together?

Yes, there are some plants that should not be planted together due to various reasons. Here are a few examples: Tomatoes and members of the nightshade family: Tomatoes, peppers, and eggplants are all members of the nightshade family and are susceptible to similar diseases. Planting them together can increase the chances of disease and pests. Cucumbers and aromatic herbs: Aromatic herbs such as sage, rosemary, and thyme can stunt the growth of cucumbers and other members of the cucurbit family. Beans and onions/garlic: Onions and garlic release compounds that can inhibit the growth of beans and other legumes. Corn and tomatoes: Both of these plants are heavy feeders and require a lot of nutrients from the soil. Planting them together can lead to competition for resources. It's important to research the specific needs and interactions of the plants you plan to grow to ensure a healthy and productive garden.
