Compatibility Analysis

Can zucchini, fennel, and lemongrass be planted together? The short answer is no, it’s not ideal to plant these three together. While zucchini and lemongrass can coexist harmoniously, fennel is known for being a poor companion plant for most vegetables, including zucchini.

• Zucchini and Lemongrass: These two can thrive together, as lemongrass can help repel pests that might otherwise target zucchini. They have similar sunlight and water requirements, making them compatible companions.

• Fennel: This plant tends to inhibit the growth of other plants due to its allelopathic properties, which can release chemicals into the soil that stunt the growth of nearby plants. Therefore, it’s best to keep fennel separate from both zucchini and lemongrass.
