Corn

Corn is ideal as a companion. It provides natural shade to watermelon during the hottest part of the day allowing the watermelon to survive in the midday heat.

Beans

Beans are a leguminous plant is helpful as it holds the nitrogen within the soil and enhances its quality. This ensures better nourishment for the watermelon plants.

Radishes

Radishes are useful companions that grow very quickly. Having shallow roots, they can be easily harvested and help in keeping the area free from weeds when the watermelons start growing. They are also helpful in repelling pest attacks.

Lettuce

Lettuce is also helpful as a companion because it covers the ground suppressing the weeds before the watermelon starts to mature. This also creates room for the watermelon vines to spread evenly.

Flowering plants

Watermelons depend on insects to help them in fruit production. Therefore, flowering plants with attractive fragrances like marigold, borage, and lavender are good companions. These flowers save the watermelon leaves and tendrils from microorganisms causing diseases. They also add beauty to your garden by adding a splash of their varied hues.

Nasturtiums

Does Spacing Matter?

Watermelons are large-sized fruits. So, to grow them properly you need to ensure that you have ample space in your garden for the vines to spread. If you space the watermelon close to the other companion plants, the growth of all the plants will be compromised.

The spacing depends on the variety of watermelon that is being grown. If you have planned to cultivate the small bushy type variety, then a gap of 3 feet should be fine. In case you have planned to go for the giant ramblers you need to keep spacing of at least 12 feet.

When watermelons are grown in rows, it is advisable to have a space of at least 4-5 feet between the plants. The rows need to be placed 6 feet apart. With this, you can plant companion plants accordingly.

Should Watering Be The Same?

All plants should not have the same watering pattern. The watering of watermelon and its companion plants will also differ based on the type of companion plant and the amount of water it requires.

Watermelons need plenty of water regularly for their proper growth. As much as 16 gallons of water every week should be ideal for them. However, excessive watering at the plant base might wet the foliage leaving the plant vulnerable to fungal diseases.

You should be limiting watering the plant before a week of harvesting it. Dry soil will help in the concentration of the sugars inside the fruit and make it sweet.

Is Thinning Necessary?

If the soil is rich in nutrients, thinning can be avoided if the mounds or the hills on which the melons are growing are properly spaced. The same thing is applicable if there is sufficient rainfall and the soil can retain moisture. Otherwise, it is not a good option to have many plants growing close together when moisture and nutrients are scarce in the soil.

Do They Promote Growth?

Some companion plants provide support, strength, and the required nutrition to the main plant. Their presence stimulates the growth and ensures a better plant life and fullest development.

A temperature ranging within 70-90F is perfect for them. Full sun is necessary for their growth.

It is better to avoid growing plants like cucumber, summer squash, winter squash, and pumpkin near watermelon plants. Potatoes can attract different species of aphids when planted close. Planting tomatoes and peppers within proximity is not a good idea. Tomatoes have dense foliage. Proper air circulation is needed to prevent plant diseases and encourage growth.

Having corn planted near the melons is a good option but they should be planted in such a way that they don’t tower over the fruit and allow it to grow naturally using enough sunlight.

Keep crops like squash, cucumber, and zucchini away from your watermelon crop. These plants attract insects like cucumber beetles that damage the crop.

Avoid growing plants like mustard, rose nearby. These plants will take away the sweetness from the leaves and harm their proper development. They are also best known for attracting aphids.

Growing watermelons close to black walnut trees is not recommended. It can be a serious threat to the young plant as its vine starts growing. The juglone of the walnut can hamper the watermelon’s growth and fruit production. It can also delay the germination of the seeds.

Flowers like aster and sunflowers are the most favorable targets for aphids. So, it is recommended not to plant them nearby.

Watermelons need a lot of space for proper growth. If they are planted too close to each other their growth might be stunted.

What Happens If You Do Plant Incompatible Plants Together

Unfavorable companion plants might stunt growth and also attract harmful insects that might destroy the entire crop. Bigger or taller companion plants tend to curb the growth of the neighborhood plants. Certain plants lead germination to stop and also rob off vital nutrients that are essential for growth.

Are There Any Disadvantages Of Using Companion Plants?

Incompatible plant combinations: Certain combinations of plants do not work. Improper and inappropriate companion plants do more harm than benefit to the main crop. You should learn about the plants that are reliable as neighbors and will not hamper the growth of your principal crop.

Plants have different needs: Every plant is unique. Plants differ in their requirement of sunlight, soil pH, water, nutrients, temperature, etc. During the process of planting different varieties of crops, it becomes difficult to cater to the specific needs of each plant. 

Improper use of available nutrients: When the main crop continues to thrive with the companion plants, they tend to compete for water, sunlight, and soil nutrients if the plants are placed very closely together.

Growth of weeds: Different crops have different harvesting season. If the companion crop matures and is harvested before the main crop, then chances are that weeds will grow in that space. To prevent this, the main crop needs to fill in those spaces where the companion plants were removed from.

Conclusion

There are many benefits of growing companion plants near watermelon plants. However, there exist multiple opinions. While some support this popular practice, others are not quite fond of it since the benefits are not backed up by solid scientific researches. Important factors like the weather, crop density, placement of the crops should also be taken into account while choosing the right companion plant. Planting plants together should be overall beneficial for your garden only if you do your homework well and know the specific plants which can be good neighbors and contribute towards each other’s growth.
