Watermelon , being a member of the melon family , has certain plants that it should not be plant near . These industrial plant can hinder the growth and matureness of watermelon plants and may even draw diseases . It is crucial to avoid planting watermelon vine near these incompatible plants to ensure the best potential ontogenesis and yield .

1 . Cucumbers : Cucumis sativus and Citrullus vulgaris both belong to to the same industrial plant family , Cucurbitaceae . As a result , they have standardized nutrient requirements and are prone to similar diseases . Planting them together can run to competition for nutrients , water supply , and infinite , ultimately affect the growth of both plants .

2 . Zucchini : Similar to cucumbers , zucchini is also a member of the Cucurbitaceae phratry . Planting Citrullus vulgaris near courgette can result in overcrowding and increased contest for resourcefulness . Moreover , courgette can appeal pest and diseases that can easily fan out to watermelon vine plant .

3 . Other melons : It is best to forefend planting watermelon near other melon , such as cantaloupe and honeydew . These flora have similar growth habits and nourishing essential , which can lead to competition and stymy the overall development of the plants .

4 . Cucurbita pepo : While watermelon and Cucurbita pepo may seem like they could coexist , it is advisable to keep them separate . Pumpkin plant tend to be vigorous raiser and can overshadow the watermelon vine plant , depriving them of sunshine and stunting their growth .

5 . Potatoes : murphy are not compatible with watermelon vine due to their differing development habits and nutrient necessity . Planting them together can result in nutrient imbalances and melt off yield for both harvest .

On the other hand , there are certain plants that can be beneficial when plant alongside watermelon as companion plants . These plants can help deter pesterer , attract beneficial insects , and improve overall garden health . Some desirable companion plant life for watermelon include :

1 . Radishes : Radishes are know to push back pest like aphids and cucumber beetles , which can be harmful to watermelon plant . Additionally , they have shallow root systems that do not compete heavily with watermelon for nutrient and weewee .

2 . bread : Lettuces have a thick growth habit and can provide some ghost to the soil , helping to retain wet and determine temperature for watermelon plants . They also do not compete to a great extent for resource , making them suitable companions .

3 . Nasturtiums : Nasturtiums work as a natural deterrent for pests , such as aphids and squash bugs , which can affect watermelon plants . Their vibrant flowers can also draw pollinators , benefiting the overall health and fruit set of the Citrullus vulgaris plants .

4 . marigold : Marigolds are well - know for their ability to push back nematode worm and other harmful insects . found them near watermelon can aid protect the plant from these pests and promote intelligent maturation .

It is important to keep off plant watermelon near plant from the melon home , such as cucumbers and zucchini , as well as other melons like cantaloupe and honeydew melon . These plant life have similar nutritive requirements and can compete for resource , hindering the growth of all plant involved . Additionally , it is advisable to keep watermelon separate from murphy , as they have dissimilar growth habits and alimental needs . On the other hand , companion works like radish plant , lettuce , genus Nasturtium , and marigolds can be good when planted alongside watermelon , providing pestilence control and other advantage .
