However, certain plants can negatively affect their growth by competing for resources, attracting pests, or encouraging disease. Here’s a guide to seven plants you should avoid planting near cucumbers and the reasons why, helping you maintain a healthy and productive vegetable garden.

1. Aromatic Herbs (Sage, Basil, Rosemary)

Why to Avoid: Strong-smelling herbs can inhibit the growth of cucumbers by overwhelming their subtle root systems with intense aromas or essential oils that cucumbers find antagonistic.

Impact: These herbs can stunt the growth of cucumbers and reduce their yield.

2. Potatoes

Why to Avoid: Potatoes and cucumbers can share similar disease profiles, particularly blights that can devastate crops. For more information on plant compatibility, check out 7 plants to avoid planting near potatoes.

Impact: Growing them together increases the risk of disease transmission and can lead to both crops failing.

3. Melons

Why to Avoid: Melons and cucumbers are both susceptible to similar pests and diseases, such as cucumber beetles and powdery mildew.

Impact: Planting them close together can create a hotspot for these issues, reducing the health and productivity of both plants.

4. Fennel

Why to Avoid: Fennel secretes a substance from its roots that inhibits the growth of many plants, including cucumbers.

Impact: Cucumbers planted near fennel may experience stunted growth or fail to thrive.

5. Sunflowers

Why to Avoid: Sunflowers can attract several pests that are harmful to cucumbers, including aphids and beetles.

Impact: These pests can migrate from sunflowers to cucumbers, causing significant damage.

6. Cabbage Family (Cabbage, Cauliflower, Kale, Broccoli)

Why to Avoid: The cabbage family can compete aggressively with cucumbers for nutrients, water, and space. Learn more about plant compatibility in 7 plants to avoid near your eggplants.

Impact: This competition can weaken cucumber plants, making them less productive and more susceptible to disease and pests.

7. Mint

Impact: Besides stealing vital resources from cucumbers, mint can also attract pests that might harm cucumber plants.
