Learn how to grow watermelon in pots. Growing watermelon in containers allows this big, sweet and juicy fruit to grow in smallest of spaces.
Sweet and watery watermelons are without a doubt an iconic summer fruit due of their high water content and soft red flesh. Those supermarket melons can’t be like homegrown fresh and organic melons. You can even plant them in a small space like a balcony, it is possible by growing watermelon vertically in a pot.
Propagation and Planting Watermelon in Pot
Watermelon has long taproot and it doesn’t transplant well that’s why it is better to sow the seeds directly in a pot. Sow 3-4 seeds directly in a pot once the temperature starts to reach 65 F (19 C) and above in the spring. In tropics (USDA Zone 10-11), the best time to sow seeds is winter and early spring. The germination takes place within 6 to 10 days. Thin out and leave only one of the strongest seedlings per pot.
Choosing a Pot
Growing watermelon in containers is not much difficult though tricky. You need to understand the basics. As watermelon has long taproot choosing a deep pot is essential. A large pot or bucket that is at least 2 feet deep and half wide is required.
Requirements for Growing Watermelon in Containers
Watermelons should be grown in a sunny position. If you’re growing it on a balcony or on a roof garden where space is tight, growing watermelon vertically on a trellis is a solution. Trellis should be minimum 4 feet tall and sturdy enough to carry the weight of melons.
Watermelons are warm weather annuals but they can be planted in both tropical and temperate regions easily. It is possible to grow watermelons in temperature around 50-95 F (10-35 C). The optimum growing temperature is around 65-85 F (18-30 C).
Sandy and loamy soil is suitable for growing watermelons. Ideal soil pH is around 6 – 6.8. Avoid compact, clayey soils. Airy and well-drained substrate promotes the growth of the plant. Also, application of the well-rotted horse, rabbit or cow manure improves the texture of soil and provides nutrients constantly.
Watermelon requires a lot of water. Keep the soil evenly moist but not wet, the water must drain freely from the bottom. When growing watermelon in containers, you’ll need to water the plant every day and sometimes twice in a warm day. Once the fruits start to swell up and mature, reduce the watering. In that period, water carefully and moderately. Avoid overwatering and underwatering both to get the sweetest melons.
