Why it works: The strong aroma of lemongrass repels pests like aphids, whiteflies, and spider mites, which commonly target ginger. This makes it a natural pest deterrent. Additionally, lemongrass can help keep the soil moist, creating a more favorable environment for ginger’s growth.
-
Additional benefits: Lemongrass can act as a windbreak, protecting ginger from harsh winds. The tall grass also provides shade to ginger, helping to maintain a cool and humid microclimate around the plant.
3. Garlic
Garlic is an easy-to-grow herb that pairs well with ginger and provides several advantages in the garden.
-
Why it works: Garlic has strong insect-repelling properties. Its scent deters pests such as aphids, ants, and slugs that might otherwise damage ginger plants. Additionally, garlic is a natural fungicide, helping to prevent fungal infections that could affect ginger’s health.
-
Additional benefits: Garlic’s roots are shallow and won’t compete with ginger for nutrients. It can also help with soil aeration, promoting better water drainage and root development for ginger.
4. Chili Peppers
Chili peppers thrive in warm environments, just like ginger, and their strong odor can provide a protective benefit for your ginger plants.
-
Why it works: Chili peppers deter pests such as aphids, caterpillars, and spider mites, which may damage ginger plants. The heat from chili peppers also doesn’t compete with ginger for resources, making them a compatible companion.
-
Additional benefits: Chili peppers can promote airflow around ginger plants, preventing the development of fungal diseases. Additionally, chili peppers attract pollinators like bees, which can support the growth of any flowering plants near ginger.
5. Mint
Mint is another herb that thrives in warm and humid environments, making it suitable for ginger.
-
Why it works: Mint’s strong smell repels a variety of pests, including aphids, ants, and flea beetles. By growing mint alongside ginger, you can help protect the ginger plants from these pests.
-
Additional benefits: Mint grows quickly and helps to suppress weeds, giving ginger more space to grow. Its rapid growth can also provide ground cover, which helps maintain soil moisture, a crucial element for ginger’s development.
6. Basil
Basil is a fast-growing herb that provides several benefits when planted alongside ginger.
-
Why it works: Basil helps repel insects such as mosquitoes, aphids, and flies. These pests can damage ginger’s foliage and roots. Additionally, basil’s strong scent helps mask the aroma of ginger, making it more difficult for pests to locate it.
-
Additional benefits: Basil’s dense foliage can provide some shade for ginger, helping to keep the soil cooler. The plant also attracts pollinators like bees, improving the overall health of the garden ecosystem.
7. Sweet Potatoes
Sweet potatoes are another root crop that pairs well with ginger, particularly in a mixed garden system.
-
Why it works: While sweet potatoes require a lot of nutrients, they benefit from the addition of organic matter to the soil, which ginger can provide. The two crops can share the same growing space without competing too much for resources, as sweet potatoes spread across the ground while ginger grows upward.
-
Additional benefits: Sweet potato vines act as a ground cover, preventing weeds from competing with ginger for nutrients. The vines also help retain moisture in the soil, ensuring a consistent water supply for ginger.
8. Comfrey
Comfrey is a perennial herb that has several beneficial properties that can support ginger’s growth.
-
Why it works: Comfrey has deep roots that break up compacted soil and improve soil structure. Its leaves are rich in nutrients, particularly potassium, which is essential for root crops like ginger. Comfrey also acts as a natural mulch, helping to retain soil moisture and protect the soil from erosion.
