Why do I need Companion Plants to grow Pumpkins?


Companion plants are plants that are planted near other plants with the intention of providing a beneficial effect to one or both of the plants. Companion planting has been used for centuries as a way to improve crop yields and ward off pests and diseases. Not all companion plants have a positive effect on pumpkins – some can even be harmful. Some good companions for pumpkins include beans, carrots, celery, cucumbers, lettuce, onions, and tomatoes. There are also a number of plants that should never be grown near pumpkins, including potatoes, garlic, chives, and sage. Pumpkin plants with a companion always produce the best yield.

Vegetables that Grow Well With Pumpkins


Early Native Americans used to plant corn, beans, and pumpkins together in order to enjoy the most of their mutually beneficial relationship. These plants help each other retain water and nutrients, and corn also functions as an anchor for pumpkin plants, a trellis for pole beans, and provides moist soil.

Bush beans

Bush beans are a nitrogen fixer, meaning they add nitrogen to the soil. This is beneficial for plants like corn and pumpkin, which are nitrogen-hungry. Pole beans are companion plants to pumpkins and provide support for vertical growth. They also add nitrogen to the soil.


Tomatoes and pumpkins are two of the most popular garden vegetables. While they both grow well in many regions, there are a few things to keep in mind when planting them together. First, make sure they are at least two feet apart so they don’t compete with each other for space and nutrients. Second, pumpkin plants do well when planted on the edge of the tomato plant row – this makes harvesting easier. Finally, tomatoes are a warm-weather crop while pumpkins prefer cooler weather – if you live in a warmer climate, you may want to wait to plant your pumpkins until late summer or early fall.


Asparagus is a perennial vegetable that takes 3 years to establish its roots. Once it is established, asparagus can continue to produce for decades. However, events in one year impact the next year’s growth and output. For example, if you harvest all of the asparagus spears in one year, the plant will not produce any spears the following year.


Radishes are a great companion plant to pumpkins because they will trap flea beetles. Flea beetles prefer radishes and will not attack the pumpkin plants as much if they are planted together. Radishes also help to divert pests from attacking the pumpkin plants.



Marigolds are a type of flower that can be found in many gardens. They are plant companions for vegetables and help to repel pests. They also attract bees and other helpful insects, which can help to pollinate your garden.


Lavender is an herbaceous plant that is part of the mint family. Lavender can be used for culinary and medicinal purposes, and it also has a variety of other uses. One such use is as an insect repellent. Lavender is beneficial to plants because it attracts pollinators like bees and butterflies, which help to protect them from pests. Additionally, lavender can be added to pumpkin plants to give them a sweet flavor.


Nasturtiums are a type of flowering plant that is often used in gardens. They have many benefits, including repelling pests for other plants in the garden, such as pumpkins. Additionally, they help attract beneficial insects to the garden, which can help with pollination and pest control.


Cosmos are beneficial to pumpkins in a few ways. For one, the pollinators that visit the cosmos also visit the pumpkins, helping to spread pollen and increase fruit set. Additionally, the presence of the cosmos seems to deter pests from attacking the pumpkin plants, leading to healthier plants and more fruit.


Sunflowers are a great addition to any garden. They have thick stalks that can be used as a trellis, they attract beneficial pollinators and repel some harmful pests, and there are a variety of pumpkin varieties that can be grown together without taking up too much space.



Like pumpkins, melons are plants that attract bees. They also have the added benefit of attracting earthworms, which aerate the soil and help to improve its quality. Additionally, when the pumpkin plant is allowed to grow alongside the melon plant, it helps to protect the melon from weeds. This is because the pumpkin vine grows quickly and densely, forming a natural barrier against weed growth.



Marjoram is a great herb to plant in your garden. It attracts beneficial insects, such as ladybugs, and helps pumpkins. Additionally, it can be used in cooking or medicinal preparations.


Oregano is a versatile herb that has many uses. It can be grown as a cover crop or living mulch, making it an important part of organic farming. It is also used as a culinary herb and has medicinal properties. Some varieties are very easy to grow in the tropics, but it does need good drainage. Oregano grows relatively quickly and does not require much soil to grow.


Tansy is a plant that can be cultivated with pumpkins. It has a number of benefits, including repelling Japanese beetles and increasing potassium levels. Additionally, it is an ornamental plant.


Mint is a herbaceous perennial that produces vibrant blue-purple flowers during the springtime. It does not require much effort to maintain and will attract more than just hummingbirds. Some other animals that are known to be drawn to mint include butterflies, bees, and wasps.
