Nothing says summer like a fresh watermelon! While many gardeners enjoy these tasty treats, many worry about their long, sprawling vines and intensive needs. Thankfully, it is possible to grow delicious melons in a small garden with a few simple tips.
Select Early, Smaller Varieties
Not all watermelons produce huge 25 pounds fruits. There are many smaller varieties that have more compact vines and produce earlier than their large counterparts, but they’re just as sweet! Here are a few of our favorite options:
- Blacktail Mountain Watermelon
- Golden Midget Watermelon
- Early Moonbeam Watermelon
- Sugar Baby Watermelon

Plant At Least Three Vines
Watermelons require pollination to set fruit. Try to grow at least three plants to ensure your watermelons receive adequate pollination.
Use Sturdy Trellises
Watermelons will climb trellises, allowing you to save tons of space in your small garden! Just beware: these long vines and heavy fruits demand sturdy structures. Metal cattle panels with metal T-posts work well.
As the fruits develop, they will need extra support to avoid damaging the vine. Use pieces of old t-shirts, nylon stockings, or other stretchy material to create a little sling or hammock under each watermelon.
Feed Your Watermelons Well
Watermelons are heavy feeders! To grow great melons, you need fertile soil. There’s no way around it. Especially in a small garden that sees a lot of use, it’s critical to provide extra nutrients. Start the season by adding several inches of finished compost to your beds.
Side-dress or fertilize your watermelons twice during the season. Once when the vines begin to run and again when they have just begun to set fruit. You can use an organic fertilizer or other amendment that’s rich in nitrogen.
Use Large Containers
As long as you have good trellises and can feed your plants, you can even grow watermelons in containers. Large containers like those made from upcycled totes or blue 55-gallon barrels work well. No matter what you use, ensure your container has drainage holes in the bottom.
Watermelon plants growing in containers will demand more attention than field-grown plants. You’ll need to water and fertilize more frequently.

Avoid Crowding Your Plants
Plant watermelons 12 to 18 inches apart. It can be tempting to squeeze as many plants in as possible, but this can weaken your plants and reduce your harvest. If you plant them too closely, your watermelons will compete for nutrients and space.
Watermelons are also highly susceptible to fungal diseases like Alternaria leaf spot, anthracnose, and gummy stem blight, especially in humid climates like the Southeast. Appropriate spacing will help ensure your plants get good airflow and reduce the risk of disease.
Keep Up with Weeding When Plants are Small
Weeds compete with young watermelon plants for nutrients, moisture, and light. They also restrict airflow, which can contribute to fungal diseases. As the plants begin to grow and sprawl, weeding without damaging the vines becomes tricky. Keeping up with weeds when the plants are small is key.
Watch for Pests
No matter how big or small your garden, you might find aphids and cucumber beetles. Encouraging beneficial insects and managing your garden well can help prevent these pests, but once you spot them, you’ll want to take immediate action.
If you have just a couple of plants, handpicking into a bucket of soapy water can be an option with cucumber beetles. For both the beetles and aphids, you can also spray the plants with soapy water. Do this in the evening to avoid burning the vines.

Water Watermelons Wisely
Watermelons thrive with consistently moist soil, but how you water matters. As discussed above, watermelon plants are sensitive to fungal diseases. Aim to keep your soil moist but not soggy. Use soaker hoses, irrigation, or hand watering to direct water directly to the plants’ roots. Avoid wetting the leaves as much as possible.
Manage the Blossoms Later in the Season
If you live in a northern climate or are growing late-season watermelons, your plants may continue producing blossoms as autumn approaches. It’s likely that these blooms won’t have the chance to reach maturity before frost.
If you notice new blossoms forming within 50 days of your average first frost, it’s best to pinch them off. This will ensure the remaining larger melons have plenty of energy to ripen before the frost.
Watermelons are one highlight of summer. With careful management, you can grow amazing watermelon vines even in a small garden.
