When it comes to sweet potatoes, companion planting can play a pivotal role in their growth and success. Let’s delve into the world of companion plants for sweet potatoes and uncover their incredible benefits.

Understanding Companion Plants

Companion plants are species that thrive when grown in close proximity to one another. This practice is rooted in the principle of mutualism, where plants interact positively, providing each other with nutrients, shade, pest control, and other essential support.

By harnessing these natural relationships, gardeners can create harmonious ecosystems that mimic nature’s balance, leading to healthier plants and higher yields.

From annual crops like potatoes, to perennial plants such as strawberries, every plant can benefit from companion planting!

Pests Deterrent Plants

Pests deterring plants are either going to be so repulsive in smell, that the bad bugs move on, or it will become what they call a ‘trap crop’, by being so pleasant to the pests that they go there instead of the main crop.

1. Lavender (Lavandula spp.): Lavender, with its aromatic blooms, acts as a natural deterrent against a myriad of pests including moths, fleas, and mosquitoes, keeping them at bay from your sweet potato patch. Its potent fragrance, attributed to compounds like linalool and linalyl acetate, creates an environment unsuitable for pests to thrive, providing a protective barrier for your sweet potatoes.
2. Chrysanthemums (Chrysanthemum spp.): Chrysanthemums are not just a burst of vibrant color but also a powerful ally in pest control. They contain pyrethrin, a potent insecticide that repels and eliminates various pests like aphids, beetles, and spider mites that could otherwise pose a threat to your sweet potatoes. Placing chrysanthemums strategically around your garden can help safeguard your sweet potato crops from potential infestations.
3. Garlic (Allium sativum): The pungent aroma of garlic not only adds flavor to your culinary dishes but also serves as a natural deterrent for pests such as aphids, spider mites, and root maggots. Its sulfur compounds, including allicin and diallyl disulfide, create an environment that pests find unfavorable, helping to protect your sweet potatoes from damage caused by these intruders.
4. Rosemary (Rosmarinus officinalis): Rosemary, with its woody stems and fragrant foliage, acts as a barrier against pests like cabbage moths, bean beetles, and carrot flies. Its aromatic oils, including camphor and cineole, disrupt pests’ ability to locate and settle on sweet potato plants, providing effective protection against potential infestations.
5. Basil (Ocimum basilicum): Basil’s distinct aroma not only enhances your culinary creations but also repels unwanted pests such as mosquitoes, flies, and aphids. Compounds like eugenol and citronellal found in basil create an inhospitable environment for pests, making it an excellent companion plant for sweet potatoes.
6. Tansy (Tanacetum vulgare): Tansy’s strong scent serves as a natural deterrent for pests like ants, fleas, and cabbage worms, keeping them away from your sweet potato crops. Its volatile oils, including camphor and thujone, create an environment that pests find inhospitable, offering protection to your precious harvest.
7. Dill (Anethum graveolens): Dill not only adds a unique flavor to your dishes but also attracts beneficial insects such as ladybugs and lacewings, which prey on aphids and caterpillars that can harm sweet potato plants. Its umbrella-shaped flowers provide nectar and pollen, creating a welcoming habitat for these natural predators.
8. Coriander (Coriandrum sativum): Coriander’s delicate foliage not only adds zest to your culinary endeavors but also attracts hoverflies, which feed on aphids and other small insects that could potentially damage sweet potato crops. By incorporating coriander into your garden, you encourage the presence of these beneficial insects, contributing to natural pest control.
9. Fennel (Foeniculum vulgare): Fennel’s feathery foliage attracts beneficial insects such as parasitic wasps and hoverflies, which prey on aphids, caterpillars, and other pests that may threaten sweet potato plants. Its aromatic flowers provide a source of nectar and pollen, creating an inviting environment for these natural predators.
10. Onions (Allium cepa): Onions, with their characteristic pungency, repel pests like aphids, carrot flies, and cabbage worms, deterring them from infesting sweet potato crops. Compounds such as allicin and allyl sulfide present in onions create an environment that pests find inhospitable, offering protection to your garden bounty.

Growth, Soil & Flavor Enhancing Plants

From enriching the soil with essential nutrients to unlocking tantalizing flavors, each of the following plants offers a unique contribution to the flourishing ecosystem of your sweet potato patch. Let’s explore the transformative potential of these companions as we delve into their remarkable benefits and the profound ways in which they elevate the gardening experience.

1. Comfrey (Symphytum officinale): Comfrey, with its deep-reaching roots, accumulates essential nutrients such as potassium, phosphorus, and calcium in its leaves. When used as mulch or added to compost around sweet potato plants, comfrey provides a slow-release source of nutrients, promoting healthy growth and development.
2. Yarrow (Achillea millefolium): Yarrow’s extensive root system mines potassium, phosphorus, and trace minerals from the soil, enriching it with essential nutrients. Incorporating yarrow into your garden as mulch or compost enhances soil fertility and structure, supporting robust growth and optimal health for sweet potato plants.
3. Borage (Borago officinalis): Borage, with its deep taproot, draws up potassium, calcium, and other minerals from the soil, enriching it with essential nutrients. When used as mulch or added to compost, borage leaves contribute to soil fertility, promoting vigorous growth and enhancing the flavor of sweet potatoes.
4. Alfalfa (Medicago sativa): Alfalfa, as a nitrogen-fixing legume, enriches the soil with nitrogen, a vital nutrient for plant growth. Whether used as a cover crop or green manure, alfalfa enhances soil fertility and supports healthy development, resulting in increased yields and improved flavor for sweet potatoes.
5. Clover (Trifolium spp.): Clover’s nitrogen-fixing abilities improve soil fertility and structure, making it an excellent companion for sweet potatoes. Whether grown as a cover crop or incorporated into the soil, clover adds nitrogen and organic matter, enhancing soil health and supporting robust growth and flavor development in sweet potatoes.

From deterring pests to enhancing soil fertility and flavor, these companion plants unlock the full potential of your garden, creating a balanced ecosystem where each plant contributes to the success of the whole. So, roll up your sleeves, embrace diversity in your garden, and watch your sweet potatoes flourish like never before.
