Growing zucchini produces abundant, flavorful fruits.
However, zucchini is vulnerable to pests like aphids, squash bugs, and cucumber beetles, which can damage leaves and spread diseases. It's also prone to fungal issues such as powdery mildew and downy mildew, leading to plant decline.
Fortunately, companion planting offers a natural and effective solution to these problems. By strategically planting certain herbs, flowers, and vegetables alongside zucchini, you can enhance plant health, deter pests, and reduce disease incidence.
With its bright, vibrant flowers in shades of orange, red, and yellow, nasturtium adds a splash of color to your garden.

Note:
While companion planting can significantly benefit zucchini, it's important to be aware of certain plants that should not be planted near zucchini.
1. Potatoes
Potatoes and zucchini are both heavy feeders, meaning they require a lot of nutrients from the soil. Planting them together can lead to competition for these essential nutrients. Moreover, potatoes are susceptible to similar pests and diseases as zucchini, such as squash bugs and blight, which can easily spread between the plants.
2. Pumpkins
Pumpkins, like zucchini, belong to the cucurbit family. Planting them together can lead to competition for space, light, and nutrients, as both plants have sprawling vines that need ample room to grow. This competition can result in reduced yields and increased susceptibility to diseases and pests common to cucurbits.
3. Cucumbers
Cucumbers are another member of the cucurbit family and share similar growing requirements with zucchini. Planting them together can lead to overcrowding, competition for nutrients, and increased risk of disease transmission, such as powdery mildew and cucumber beetles.
4. Fennel
Fennel is known to inhibit the growth of many plants, including zucchini. It releases allelopathic chemicals into the soil, which can stunt the growth of neighboring plants. To avoid this negative interaction, it’s best to plant fennel well away from your zucchini.
5. Melons
Melons, like pumpkins and cucumbers, are cucurbits that require a lot of space to grow. Planting melons near zucchini can lead to overcrowding and competition for light and nutrients. Also, melons and zucchini can attract similar pests, increasing the risk of infestations.
6. Brassicas (Cabbage, Broccoli, Cauliflower)
Brassicas can attract pests like cabbage worms and aphids. They also have different soil and nutrient requirements, which can lead to imbalances in the garden soil if planted too close to zucchini.
