Companion planting is a gardening strategy that involves situating certain crops near each other to enhance their health and growth. This technique can ward off pests and diseases or enrich the soil with essential nutrients beneficial to neighboring crops. If zucchini is part of your garden plan, companion planting is worth considering.
Some great companion plants for zucchini include dill, oregano, garlic, and rosemary. Conversely, avoid planting zucchini near pumpkins, melons, and cucumbers, as they share the same family and can attract similar pests. Additionally, steer clear of planting potatoes and fennel near zucchini, as they can hinder its nutrient uptake.
Keep zucchini away from other plants that belong to the Cucurbitaceae family
Zucchini is a member of the Cucurbitaceae family, also known as the gourd family or cucurbits, which includes over 900 species such as cucumbers, pumpkins, melons, and squashes. Contrary to what one might think, planting zucchini near its family members is not advisable.
Due to shared family traits, these plants are vulnerable to the same diseases and pests, such as aphids and cucumber beetles, which can spread diseases like mosaic virus. Close proximity to pumpkins, watermelons, or squash can increase the risk of widespread disease or pest infestations.
Cross-pollination presents another risk when planting zucchini near other cucurbits, especially those within the same species (Cucurbita pepo). Cross-pollination can result in plants that produce odd-looking and less palatable fruit if seeds are saved for future planting.
Potatoes and fennel can threaten the growth of zucchini
When planning your garden, avoid planting zucchini near potatoes. Potatoes deplete soil nutrients, potentially leaving insufficient resources for zucchini growth. Both crops are also susceptible to blight, increasing the risk of spreading the disease if planted together. Consider alternative companions for potatoes, like chives, marigolds, or petunias.
Fennel should also be avoided near zucchini, as it releases toxins into the soil due to its allelopathic properties. While these toxins may not kill zucchini, they can impede its growth and reduce yield.
