What is the rule of three companion planting?

In general, plants with known positive relationships should be planted within two or three rows of each other. Plants that have negative or detrimental relationships, should be planted at least two to three rows apart. Infestation of pests or disease can occur more quickly if you plant all the same crop close together.

How do you know what to plant next to each other?

When growing different varieties of plants side by side, try to group them together by water needs . Deep-rooted vegetables like tomatoes and asparagus should be placed in the same bed, as they will thrive with less frequent (but more thorough) watering that soaks deep into the soil.

How close together do you companion plants?

Plants that have known beneficial relationships (friends) should be planted within two or three rows of each other . Plants that are known to have detrimental relationships (foes) should be planted at least 2-3 rows apart.

What not to plant with cucumbers?

Aromatic Herbs : Herbs like sage and rosemary, while useful in cooking, can inhibit the growth of cucumbers. They contain natural oils that can slow down the growth of cucumber plants. Brassicas: Plants like broccoli, cabbage, and cauliflower can compete with cucumbers for the same nutrients in the soil.

Can peppers and tomatoes be planted together?

Tomatoes. Although it's usually recommended to not plant tomatoes and peppers right after each other in the same bed every year, they can be grown together in the same garden bed (and then rotated to another bed next season).

How do I layout my vegetable garden?

As a general rule, put tall veggies toward the back of the bed, mid-sized ones in the middle, and smaller plants in the front or as a border . Consider adding pollinator plants to attract beneficial insects that can not only help you get a better harvest, but will also prey on garden pests.

Should you always plant in threes?

Here's a piece of often-repeated advice for planting perennials: Always plant in odd numbers, in groups of at least three . This is good advice. An odd number of plants can be arranged in an irregular cluster, which looks more natural than a straight line or block shape.

What are the three companion plants?

The Three Sisters planting method, commonly known as companion planting, entails growing corn, beans, and squash together in a mutually beneficial arrangement. It originated in North America around 3000 years ago.

How to Start Companion Planting (2024)

Written by: Nature's Path Posted under Better Planet, Nature's Path on June 2017

Certain plants thrive when planted in combination with others in the garden. They boost growth, repel pests, and improve flavor for each other. Aside from the benefits to your plants, companion planting uses your garden space more efficiently, letting you harvest more. The diversity that companion planting provides is also good for pollinators, wildlife, and soil health.

Plant compatibility

In a natural ecosystem, plants grow together because they are compatible. They attract beneficial insects and pollinators, deter unwanted pests, and offer shelter and food for other critters. The plants provide each other things they need, be that nutrients, shade, or physical support.Companion planting in the home garden is an imitation of those symbiotic relationships. The best known in the wild and the garden are the Three Sisters – corn, beans, and squash. In this ancient planting system, the corn gives support to the pole beans, which feed much needed nitrogen to the corn and squash. The leaves of the squash act as mulch to keep the ground cool, suppress weeds, and conserve moisture.

A few companion planting combinations

Basil

Protect your tomatoes from hornworms with a liberal planting of basil. Peppers benefit from nearby basil and tomatoes, too. The ingredients for spaghetti sauce are compatible in the garden as well as in the kitchen!

Marigolds

The strong aroma of Marigolds deters cabbage moths, as well as Mexican Bean Beetles, which can decimate a bean crop quickly. The scent also keeps mammals, such as rabbits, away from your garden.

Nasturtiums

These are a good companion plant for broccoli, cabbage, and other members of the brassica family. Cabbage loopers are very destructive to these crops. When cabbage moths lay their eggs on the leaves, a caterpillar hatches and eats its way to adulthood, destroying your plants. If there are nasturtiums nearby, they will lay their eggs on their leaves instead, sparing your garden.

Dill

When planted with brassicas, Dill attracts a beneficial wasp that keeps cabbage loopers in check.

Corn

Tall plants, such as corn, will provide shade for leafy greens that do not need full sun and grow better in a cool environment.

Borage

A herb (with edible flowers!), borage will attract pollinators to your garden to boost your harvest.

As companion plants are beneficial for each other, there are also plant combinations that are detrimental when planted closely:

Onion family plants will stunt the growth of beans and peas.
Carrots and parsley should not be planted near each other. If you give them some room, however, they will attract ladybugs, praying mantises, and other beneficial insects that dine on destructive pests like aphids.

Here is a detailed list of companion plants.

Crop rotation

Another example of plants benefitting each other is crop rotation. You should not grow the same family of plants in the same place every year. Pests and disease could be living in the soil, but without the host present, they will die off. Rotating where you plant your crops every year reducing the risk of disease and insect infestations.Just as important are the nutrients left behind in the soil at the end of the year. Certain crops can take advantage of them the following year. For instance, legumes fix nitrogen, meaning they take it from the air, and bring it down into the soil. Crops that have high nitrogen requirements, such as leafy greens, broccoli, or squash, are best planted where beans or peas were the previous year.Nutrients are also removed from the soil, and can be replenished with next year’s planting. You will have a healthier and more diverse garden when you rotate your crops every season to balance out nutrient use.With companion planting and crop rotation, you are letting the plants take care of each other. That means better production for you, and probably a little more leisure time, too!
