What to Plant with Watermelons: Best Companion Plants Fruit, Vegetable, Shrubs


Watermelons are a great summer crop, but they can be susceptible to pests and diseases. One way to help protect them is to plant companion plants around them that will attract pollinators and predators of pests. Some good companions for watermelons include buckwheat, cowpea, and sweet clover. These plants will not only help protect the watermelon from pests, but they may also promote higher yields. It is best to plant these companion plants three weeks before you plan to plant your watermelons so that both crops will be blooming at the same time.

As watermelon is a vining crop, it is important to companion plant it with other plants in order to discourage pests and improve soil quality. Radish, tansy, and nasturtium are effective companion plants that can be interplanted with watermelon. Additionally, the ‘Blue Hubbard squash can be used as a trap crop to lure pests away from the watermelon vines. Finally, before hairy vetch blooms, it should be cut back and the residue left on the garden bed as a mulch to decrease diseases like Fusarium wilt, anthracnose, and gummy stem blight.

‘Sugar Baby’ Watermelon

Sugar Baby watermelons are a type of melon that is becoming more popular. They are smaller than other types of melons and have a sweet flavor. In order to yield well, they need plenty of sunlight. Avoid planting them near other crops that will shade them and include flowers like dill, chamomile, cosmos, and pineapple sage to attract predators. Local predator insects eat melon pests.

Plants That Are Compatible with Watermelon

Watermelons are a large crop and need plenty of space to grow. They also require a lot of sunlight, so companion planting is a great way to make use of space and get the most out of your garden. Companion plants are chosen specifically because they complement the needs of watermelons- for example, plants that help repel insects or offer protection from diseases. Companion planting is used by gardeners all around the world to increase their yields and get the most out of their crops.

Watermelon plants are a great choice for gardeners looking to add some color and sweetness to their summer gardens. However, when it comes to planting these succulent fruits, there are a few companion plants that gardeners can use to obtain a higher yield and make sure all of their crops stay healthy. Companion planting is beneficial because it allows different types of plants to help each other out – for example, taller plants can provide shade for smaller plants while they grow, or herbs can deter pests from attacking other plants. Planting plants that are compatible is a great way to make the most of your garden space, but it’s important to note that not all plants get along. For example, planting tomatoes near watermelon can actually stunt the growth of the watermelon plant. So, when planning out your garden, be sure to do your research and choose wisely!
