Are you curious about companion planting and how it can benefit school gardens? Look no further! In this article, we will explore the basics of companion planting and why it is essential for successful school gardens. You will learn how to create plant partnerships that will promote healthy growth, protect against pests, and increase yields. Let's get started!
What is Companion Planting?
Companion planting is the practice of growing different plants next to each other, so they can mutually benefit each other. This gardening technique has been used for centuries, and it is based on the idea that some plants can improve the growth of others due to the exchange of nutrients, improved soil conditions, or pest control.
Companion planting is a natural and sustainable way to increase crop yields and reduce the use of chemical pesticides and fertilizers. By cultivating a diverse range of plants, you can discourage harmful insects and attract beneficial ones, enhance soil health, and promote biodiversity.
Why is Companion Planting Important for School Gardens?
School gardens are an excellent tool for teaching students about the environment, nutrition, and sustainability. They provide a hands-on experience that allows young learners to learn the basics of gardening and develop an appreciation for fresh, healthy food.
Companion planting is particularly important for school gardens because it is a low-cost, low-risk method for increasing crop production and improving soil health. Additionally, it provides a natural way to manage pests without exposing students to harmful chemicals.
Companion planting is also an excellent opportunity to teach students about the interdependence of plants and the importance of biodiversity. By growing different plants next to each other, students can observe how different species can benefit each other and contribute to a healthy ecosystem.
Examples of companion plants and their benefits for school gardens
Companion planting is all about teamwork and mutually beneficial relationships, and school gardens are the perfect place to teach students about it. Certain plants can help other plants grow, improve soil quality, attract pollinators, repel pests, and add beauty to a garden. Here are some examples of companion plants that can thrive in school gardens and their benefits:
- Marigolds: These colorful flowers not only add beauty to a garden but also have natural insect-repelling properties. Their strong scent can deter pests like beetles, aphids, and nematodes from nearby vegetables. Marigolds are also easy to grow and can tolerate a wide range of growing conditions.
- Nasturtiums: Another flowering plant that can repel pests like squash bugs and whiteflies. Nasturtiums have a peppery taste, and their leaves and flowers are edible and rich in vitamin C. They also attract aphids away from other plants, so they make a great sacrificial plant. Nasturtiums prefer full sun and well-draining soil.
- Basil: This fragrant herb is a perfect companion for tomatoes, peppers, and eggplants. It repels tomato hornworms, mosquitoes, and flies and attracts bees and other pollinators. Basil is also easy to grow from seed in a sunny location with fertile, well-draining soil.
- Beans: Beans are excellent nitrogen-fixers that can improve the soil quality for other plants. They work well when planted with corn and squash, in a grouping called the "Three Sisters." Corn provides structure, squash shades the ground, and beans fix nitrogen. Beans prefer full sun and well-draining soil.
- Sunflowers: These towering flowers attract pollinators like bees and butterflies and can also provide shade for other plants. They also have allelopathic properties, which means they release chemicals that can suppress weed growth. Sunflowers prefer full sun and fertile, well-draining soil.
- Lavender: This fragrant herb repels pests like mosquitoes, moths, and fleas and attracts pollinators like bees. Lavender prefers full sun and well-draining soil and can also add beauty to a garden with its purple flowers.
By incorporating companion planting into school gardens, students can learn about the power of teamwork in nature and how to create a thriving ecosystem that benefits all living things. They can also get hands-on experience in planting, caring for, and harvesting a diverse range of plants.
How to Plan and Design a Companion Planting Layout for Your School Garden
Companion planting can be a fun and efficient way to maximize the use of space in your school garden while promoting biodiversity and deterring pests. Here are some steps to help you plan and design your companion planting layout.
- Identify companion plants that work well together: Not all plants thrive when planted together. For example, some plants attract pests that can damage neighboring plants. Do some research to identify plant combinations that complement each other and provide mutual benefits. For instance, planting tomatoes alongside basil or marigolds can help deter pests.
- Consider planting time and growth habits: When planning your garden, consider the timing of planting and the growth habits of each plant. Plan to plant taller plants in the back and shorter plants in the front to ensure that each plant gets enough sunlight and resources.
- Figure out the right amount of space: Ensure that you have enough space for each plant to grow. Overcrowding can lead to stunted growth and can attract pests. Consider spacing your plants according to their individual needs and their companion’s needs.
- Create a map: Creating a diagram or map of your school garden can assist you in visualizing the space and planning where individual plants go. Label each plant with its name, plant family, and expected growth height.
- Rotate crops: To prevent soil-borne diseases and maintain healthy soil, rotate your crops every season. For example, if you planted tomatoes in one area last year, you should plant a different plant family in that location this year.
- Record and observe your plants: Keep a detailed record of what you’ve planted and how your plants are doing. Take note of which plants thrived and which plants didn’t do well. This will provide you with valuable information when designing your garden in the future.
With proper planning and design, companion planting can be a fun and engaging way to enhance the biodiversity of your school garden and promote healthy plant growth. Take the time to research, plan, and observe your plants to ensure a successful garden year after year.
Tips for maintaining a successful companion planting system in your school garden
Now that you have learned the benefits and basic principles of companion planting, it's time to put that knowledge into practice and maintain a successful companion planting system in your school garden. Here are some tips to help you out:
Choose appropriate plant combinations: When selecting plants to grow together, make sure they have complementary growth habits, such as tall plants with low-growing ones, and that they don't compete for the same nutrients. Additionally, choose plants that have natural pest-repellent properties, such as marigolds and basil, to protect each other from harmful insects.
Plan your layout: Consider the space available in your garden and plan your companion planting layout accordingly. Group plants according to their light requirements and growth habits to ensure that they'll get along well together and won't cause shade or overcrowding issues.
Rotate your crops: For a healthy and successful garden, it's important to rotate your crops every season. This helps prevent soil-borne diseases and pests that can build up over time, as well as maintain proper nutrient levels in the soil.
Provide proper care: Just like any other plants, companion plants require proper care and maintenance. Water them regularly, fertilize when necessary, and weed regularly to avoid competition for nutrients and space.
Monitor for pests and diseases: Keep an eye out for any signs of pests or diseases that may be affecting your companion plants. Use organic and natural methods to control these issues, such as hand-picking insects, using companion plants with pest-repellent properties, and using organic sprays.

Move your plants around each season to prevent this from happening.
Not understanding the purpose of companion planting: It's important to understand the purpose of companion planting. Some plants are grown together because they repel pests, while others are grown together because they help each other grow. Make sure you know why you're planting certain plants together.
Not considering the needs of the plants: Each plant has its own specific needs for soil, sunlight, and nutrients. When companion planting, it's important to consider the needs of each plant and group companions that have similar requirements.
By avoiding these common mistakes, you can ensure your school garden is successful and provides a bountiful harvest. Happy planting!
The long-term benefits of companion planting for school gardens and the environment
Companion planting is not only beneficial for school gardens in terms of increasing plant yield and preventing pests, but it also has long-term benefits for the environment.
Soil health: Companion planting helps to improve soil health as different plants have different root structures and nutrient needs, which means they resist pests and diseases and can later decompose and improve the soil’s texture and fertility. This ensures that school gardens can continue to grow produce in the future as the soil remains healthy.
Biodiversity: Companion planting promotes biodiversity as each plant attracts different beneficial insects that can pollinate flowers, deter pests, and even help fight plant diseases. The variety of plants in the garden also supports a diverse ecosystem that creates a balance between insects and other animals.
Reduced pesticide use: Companion planting can effectively reduce the need for pesticides. For example, planting marigolds near tomato plants repels nematodes, while planting basil near tomatoes can deter whiteflies. This means that there are fewer harmful chemicals being used in the garden and less runoff polluting nearby water systems.
Climate change resilience: Companion planting can also help school gardens become more resilient to changing weather patterns. By planting a mix of crop varieties, school gardens can become less susceptible to extreme weather events and can increase the chances of having a successful harvest despite weather challenges like drought or flooding.
Sense of community: School gardens that utilize companion planting can bring together students, teachers and the wider school community. Together, they can learn about environmental stewardship and the benefits of sustainable practices. School gardens with companion planting can be fun and interactive classrooms that engage students with the natural world in a variety of ways.
Overall, companion planting is a simple and effective way to ensure the long-term success of school gardens and promote sustainable gardening practices that can benefit the environment and local communities.
