Do you know that there are some promising companion plants for apple trees that you can go together with the fruit? Companion planting can be useful for all the involved plants. Not only can they support each other, but you can also expect a more fruitful outcome. So, what are the best companion plants for apple trees?
Garlic
Do you know that garlic is a natural repellent for pests? It’s one of the best companion plants for apple trees in a way that it will keep your apple trees safe from pests. Thanks to the strong smell, some common pests won’t come near the trees, like codling moths, apple maggots, and aphids. Not to mention that garlic is rich in natural antifungal traits, protecting the apple trees from various diseases, such as powdery mildew or apple scab.
You want to grow the (garlic) bulb surrounding the apple tree's base. Do it in autumn. When the plant grows, sulphur compounds would be released in the soil, protecting the trees. Not to mention that you will have fresh garlic supply and you can harvest it in summer time. Space up the bulbs 4 inches to 6 inches apart so the trees can enjoy the protective benefits.
Chives
Not only it repels pests, but it can enhance flavor too. The strong smell makes pests avoid coming to the trees, so you can expect Japanese beetles or aphids to stay away. Chives are also believed to improve the apple’s taste. The best thing about chives is the fact that it’s simple (and easy) to grow. Maintenance would be minimal. Let’s not forget that the purple flowers are visually appealing, especially in spring time. They can help to attract helpful insects, such as bees. Just make sure that you divide the chive plants so they won’t overcrowd.
Marigolds
Do you know that this flower can help with nematode control as well as attracting the helpful insects? That’s why it’s considered one of the best companion plants for apple trees. Because of the vibrant colors, many (beneficial) insects would be interested in coming, like hoverflies, parasitic wasps, and ladybugs.
You want to plant the marigolds within clusters, surrounding the trees. Go with French marigolds if you want to get the best and potent effect in dealing with nematodes.
Comfrey
It may be viewed as a regular herb plant with deep roots, but it can take the soil’s nutrients. You can also cut comfrey’s leaves for mulch, and they will release beneficial nutrients, such as nitrogen, calcium, and potassium. The mulch alone can boost soil fertility while encouraging healthy (and natural) growth and boosting fruit production at the same time.
Comfrey also produces clusters of purple, pink, or white flowers that attract pollinators, which are essential for apple tree fruiting. Plant comfrey at the edge of the orchard or near the base of the trees, where it can act as a living mulch and nutrient pump.
Clover
It helps with weed suppression (thanks to the dense growth) while enriching soil at the same time. White clover is particularly popular as a companion plant due to its low-growing nature, which won’t compete with apple tree roots. It can be sown as a living mulch around the base of the tree or throughout the orchard floor. Clover also attracts pollinators and beneficial insects, further supporting the health of your apple trees.
Nasturtiums
Nasturtiums are a versatile companion plant that can serve as a trap crop for aphids—a common pest of apple trees. Aphids are attracted to nasturtiums, drawing them away from your apple trees and reducing the damage they cause. Once the aphids have infested the nasturtiums, you can remove and dispose of the affected plants to control the pest population.
In addition to pest control, nasturtiums produce bright, edible flowers that attract pollinators like bees and butterflies, which are crucial for apple tree pollination. Plant nasturtiums around the base of your apple trees or along garden borders to take advantage of their benefits.
Herbs
A variety of herbs can be planted near apple trees to improve their health and productivity. Herbs like dill, fennel, and coriander attract beneficial insects that prey on pests, while others like thyme and oregano have antifungal properties that can help protect apple trees from diseases.
Herbs are also low-maintenance and can thrive in the same conditions as apple trees, making them easy to incorporate into your orchard. Plant them in clusters around the base of the trees or along the edges of the orchard to create a diverse, pest-resistant environment.
You can consider these plants if you want to enjoy the greater benefits – aside from enjoying the juicy apples. With these potential companion plants for apple trees, you can enjoy several harvests in a year without overdoing anything.
