Cucumbers are a popular and easy-to-grow vegetable that is enjoyed by many home gardeners. However, like all plants, cucumbers have specific needs and requirements to grow well. One way to ensure a healthy cucumber crop is by planting cucumber companion plants. These plants can help to deter pests, improve soil quality, and provide shade and support for the cucumber vines. In this article, we will explore the 10 best cucumber companion plants, as well as a few plants that should never be planted with cucumbers.

• Corn – Corn is a great cucumber companion plant because it provides shade for the cucumber vines and helps to deter pests like cucumber beetles.
• Beans – Beans are nitrogen-fixing plants that can help to improve the soil quality for cucumbers. They also provide support for the cucumber vines to climb.
• Peas – Peas are also nitrogen-fixing plants and can be grown as a cover crop to improve soil quality. They also provide support for the cucumber vines to climb.
• Radishes – Radishes are fast-growing plants that can be planted as a trap crop to lure pests away from the cucumbers. They also help to improve soil quality and provide shade for the cucumber vines.
• Dill – Dill is a natural insect repellent and can help to deter pests like aphids and spider mites. It also attracts beneficial insects like bees and wasps, which can help to pollinate the cucumber flowers.
• Marigolds – Marigolds are another natural insect repellent that can help to deter pests like nematodes and whiteflies. They also help to improve soil quality and provide a splash of color to the garden.
• Nasturtiums – Nasturtiums are a great companion plant for cucumbers because they attract beneficial insects like bees and ladybugs. They also help to deter pests like aphids and cucumber beetles.

While there are many plants that can be grown with cucumbers, there are a few plants that should never be planted together. These include:

• Potatoes – Potatoes and cucumbers are both susceptible to blight, a fungal disease that can quickly spread between the two plants.
• Melons – Melons and cucumbers are both members of the same family (Cucurbitaceae) and are prone to the same pests and diseases. Planting them together can increase the risk of pest and disease problems.
• Aromatics – Plants like onions, garlic, and chives can inhibit the growth of cucumbers and other plants in the same family.

In conclusion, planting cucumber companion plants can help to improve the health and productivity of your cucumber plants. By choosing plants that provide shade, support, and pest control, you can create a healthy and vibrant garden that is both beautiful and productive. However, it’s important to avoid planting cucumbers with certain plants that can inhibit their growth or increase the risk of pests and diseases. With a little planning and care, you can enjoy a bountiful cucumber harvest and a thriving garden.
