Bad Companion Plants for Zucchini
While companion planting can greatly benefit your zucchini, it’s important to know which plants to avoid. Some plants can compete for nutrients, attract pests, or stunt the growth of zucchini. By steering clear of these bad companion plants, you can ensure a healthier and more productive zucchini crop.
For instance, potatoes are not ideal companions for zucchini. They compete for nutrients and space, which can hinder the growth of your zucchini plants. Additionally, potatoes attract similar pests, increasing the risk of infestations.
Another example is fennel. Fennel secretes a substance that can inhibit the growth of zucchini and other nearby plants. This can result in stunted growth and lower yields.
Brassicas, such as broccoli, cauliflower, and cabbage, should also be avoided. These plants compete for the same nutrients and space, which can lead to reduced growth and productivity for zucchini. Moreover, they attract pests that can harm zucchini.
Lastly, pumpkins and other vining squash can compete with zucchini for space and resources. They can also cross-pollinate with zucchini, resulting in undesirable hybrid fruits.
By being mindful of these bad companion plants and choosing better-suited companions, you can create a thriving garden environment that supports the healthy growth of your zucchini plants.
