Are you interested in growing your own vegetables but don’t have a large garden space? Companion planting in containers might be the solution you’re looking for. Companion planting is the practice of growing different plants together in a way that benefits both plants. This technique can help deter pests, improve soil quality, and increase yields.
But can you companion plant in containers? The answer is yes!
Growing vegetables in containers is a great way to maximize your space and create a portable garden. However, certain plants may not thrive when grown together in the same container. Companion planting in containers requires careful consideration of the plants’ growing habits, nutrient needs, and compatibility.
For example, plants that have similar water and light requirements are good companions. On the other hand, plants that have different nutrient needs or are susceptible to the same pests and diseases should not be planted together.
If you’re new to companion planting, it can be overwhelming to figure out which plants are good companions and which ones aren’t. Fortunately, there are many resources available to guide you through the process.
In this article, we’ll explore the benefits of companion planting in containers and provide tips for choosing compatible plant combinations. So, whether you’re an experienced gardener or a beginner, you can successfully grow a bountiful container garden using companion planting techniques.
Benefits of Companion Planting in Containers
When you plant different types of plants together in a container, you can reap many benefits. Here are a few benefits of companion planting in containers:
Increased Yield
Companion planting can increase the yield of your container garden. When you plant certain plants together, they can help each other grow better.
For example, planting beans with corn can increase the yield of both plants. Beans can fix nitrogen in the soil, which corn needs to grow. In return, corn provides support for the beans to climb.
Pest Control
Companion planting can also help control pests in your container garden. Some plants can repel pests, while others can attract beneficial insects that eat pests.
For example, planting marigolds with tomatoes can repel nematodes, which can damage tomato roots. On the other hand, planting dill with tomatoes can attract ladybugs, which eat aphids that can damage tomato plants.
Improved Soil Health
Companion planting can also improve the health of your soil. Some plants can add nutrients to the soil, while others can help break up compacted soil.
Another example is planting radishes with carrots, this can help break up compacted soil, making it easier for the carrots to grow. In addition, radishes can add nutrients to the soil that carrots need to grow.
When you companion plant in containers, you can enjoy these benefits and more. Plus, container gardening makes it easier to control pests and diseases, since the plants are in a confined space.
Choosing Plants for Companion Planting in Containers
When it comes to companion planting in containers, there are a few things to consider to ensure that your plants thrive together. Here are some tips to keep in mind:
Consider Planting Needs
Before choosing companion plants for your container, it’s important to consider the planting needs of each plant. For example, some plants prefer more shade while others need full sun.
Some plants require more water while others prefer drier soil. Make sure to choose plants with similar needs to ensure that they grow well together.
Planting Compatible Plants
Certain plants are known to grow well together and can even benefit each other. Basil and dill are great companions for corn, while herbs like tomatoes and potatoes can help repel pests.
Beans and carrots are also great companions, as the beans provide nitrogen to the soil, which is beneficial for the carrots.
Shade and Sun Requirements
It’s important to consider the shade and sun requirements of your plants when companion planting in containers. For example, parsley and sage prefer partial shade, while peppers and broccoli prefer full sun.
Make sure to group plants with similar sun and shade requirements together to ensure they grow well.
Vegetable Combination Ideas For Container Gardens
When choosing companion plants for your container, here are some popular options to consider:
- Basil and tomatoes
- Carrots and parsley
- Fennel and peppers
- Broccoli and onions
- Mint and oregano
- Lettuce and asparagus
- Marigolds and squash
- Rosemary and cilantro
- Chives and spinach
- Garlic and cucumbers
- Zucchini and radishes
- Beets and kale
- Peas and thyme
- Nasturtiums and beets
- Cucumber and hyssop
- Cauliflower and strawberries
- Borage and lavender
- Eggplant and celery
When grouping plants together, consider their height and foliage. Tall plants can provide shade for shorter plants, while trailing plants can fill in gaps and add visual interest.
Mixing plants with different textures can also create a visually appealing container garden.
Companion planting can also help prevent disease problems. Planting coleus with chili plants can help deter pests, while planting green beans with mustard greens can help prevent soil-borne diseases.
To attract beneficial insects like ladybugs and repel pests like slugs, consider planting perennials like marigold or herbs like thyme and coriander.
Finally, when planting the “three sisters” (corn, beans, and squash), make sure to plant the beans first to provide nitrogen to the soil, then plant the corn and squash around them.
By considering the planting needs of your plants and choosing compatible companions, you can create a thriving container garden with healthy, happy plants.
Container Selection and Preparation
Choosing the Right Container
When selecting a container for companion planting, you need to choose one that is the appropriate size and has good drainage. The size of the container should be based on the size of the plants you want to grow and the number of plants you want to include.
A general rule of thumb is to use a container that is at least 12 inches deep for most plants.
Make sure consider the material of the container. Terracotta and clay pots are porous and allow for good airflow and drainage, but they can dry out quickly.
Plastic containers are lightweight and retain moisture well, but they may not provide as much airflow. Whichever material you choose, make sure that it has drainage holes in the bottom to allow excess water to escape. The drainage holes are really non negotiable in my opinion.
Preparing the Container
Before planting your companion plants, it’s important to prepare the container properly. Start by filling the bottom of the container with a layer of rocks or gravel to improve drainage and prevent water from pooling at the bottom.
Next, fill the container with potting soil, leaving about an inch of space at the top. If you’re planting succulents or cacti, you may want to add sand or perlite to the soil to improve drainage and prevent root rot.
Once the soil is in place, it’s time to arrange your plants. Make sure to space them out evenly and avoid overcrowding. You can use a companion planting chart to help you choose the best plant combinations for your container.
Finally, water your plants thoroughly and place the container in a location that receives the appropriate amount of sunlight for the plants you’ve chosen.
Keep in mind that container plants may require more frequent watering than plants grown in the ground, so be sure to monitor the soil moisture levels regularly.
Companion Planting Techniques for Container Gardening
When it comes to container gardening, companion planting can be a great way to maximize your space and yield a bountiful harvest.
Do companion plants need to be in the same container? While companion plants can be beneficial for each other, they don’t necessarily need to be in the same container. If you don’t have enough space in a single container, you can still utilize companion planting principles by grouping compatible plants in containers nearby.
This allows the plants to interact and share benefits, such as repelling pests or attracting beneficial insects, even if they are not directly in the same container.
In container gardening, space can be limited, making it challenging to accommodate multiple plants in a single container. However, if you have a large enough container and compatible plants, growing companions together can still be a viable option.
Here are a few techniques to consider when companion planting.
Grouping
Grouping plants together can have a number of benefits. For example, planting herbs like basil, parsley, and thyme together can help repel pests and attract beneficial insects. Similarly, planting tomatoes with basil can improve the flavor of both plants.
Here are a few other examples of plants that work well together:
| Plant 1 | Plant 2 |
|---|---|
| Carrots | Radishes |
| Cucumbers | Nasturtiums |
| Lettuce | Chives |
Succession Planting
Succession planting involves planting crops in stages so that you can maximize your harvest throughout the growing season. For example, you might plant lettuce in the early spring, followed by tomatoes in the summer, and then kale in the fall.
To make succession planting work in containers, you’ll need to choose plants with similar growing requirements and stagger their planting times. You can also use trellises or other supports to help maximize your space.
Vertical Planting
Vining plants like beans, cucumbers, and tomatoes can take up a lot of space in a container garden. However, by using trellises or other vertical supports, you can grow these plants upwards instead of outwards.
Here are a few tips for vertical planting:
- Choose plants that are naturally vining or that can be trained to grow vertically.
- Use a trellis or other support system to help your plants grow upwards.
- Be sure to provide enough water and nutrients to support your plants’ growth.
By using these companion planting techniques, you can create a thriving container garden that yields a bountiful harvest.
Which Vegetables Don’t Grow Well Together?
Certain vegetables don’t grow well together due to various reasons such as competition for resources, incompatible growth habits, or susceptibility to the same pests and diseases. Here’s a list of vegetables that are generally considered poor companions:
- Beans and onions: Onions can inhibit the growth of beans, so it’s best to keep them separate.
- Cabbage and tomatoes: Cabbage and related plants like broccoli and cauliflower may attract the same pests as tomatoes, such as cabbage worms and aphids.
- Carrots and dill: Dill can attract carrot pests like aphids and carrot flies, so it’s advisable to avoid planting them together.
- Corn and tomatoes: These two plants are both heavy feeders, and their nutrient requirements can cause competition if grown together.
- Potatoes and tomatoes: Both potatoes and tomatoes are prone to blight and can spread diseases to each other.
- Radishes and hyacinth beans: Radishes can release compounds that inhibit the growth of hyacinth beans, so it’s better to keep them apart.
- Spinach and strawberries: Strawberries have a tendency to shade out spinach, hampering its growth.
- Squash and potatoes: Squash and potatoes may compete for space and nutrients, so it’s recommended to separate them.
- Sunflowers and potatoes: Sunflowers can shade and compete with potatoes, affecting their growth and yield.
Remember that these are general guidelines, and the success of companion planting can vary depending on specific growing conditions and varieties of plants. It’s always a good idea to observe and experiment in your own garden to determine the best combinations for optimal growth and productivity.
