How to Grow Watermelons in Pots or Containers.
An appropriate pot
First, you’ll need a large pot with a diameter of 30 cm and a depth of 15 cm so that the plant can develop its extensive roots. If the ambient temperature is around 19°C, it’s time to sow 3-4 seeds in our pot. Germination takes place in 6 to 10 days. Keep only the seedling that appears the strongest. Choose a sunny location to place your pot and prepare a sturdy trellis about 120 cm high to support the weight of the fruits.
The type of soil:
The ideal soil for growing watermelons consists of a mix of sand and clay. If it’s too silty or too heavy, the plant won’t develop properly. The soil pH should be between 6 and 6.8. Before sowing, it is advisable to add a good amount of dry fertilizer to the soil. Irrigation is essential for the development of the plant and its fruits. We will keep the soil slightly moist, so under these conditions, we need to water every day and even twice when the weather is dry. When the watermelons begin to develop, watering should be reduced.
Maintenance of watermelons in pots.
Initially, they need a complete fertilizer, but once the flower appears and then the fruit, a fertilizer low in nitrogen should be used. Liquid fertilizers based on seaweed work very well at this stage. Excessive, damaged, or diseased lateral branches should be removed to leave strong central branches.
Watermelons develop male and female flowers, usually pollinated by insects. Although manual pollination can also be used if we want to ensure success. Ripe fruits appear approximately 40 days after pollination. The right time to harvest watermelons depends on several factors, including weather, season, or variety.
Watermelons can generally be harvested 80 to 90 days after planting or 30 to 50 days after flowering. An empirical method is to tap the watermelon with your fingers; when the sound is dull, like a thud, it is ripe. It is also recommended to pay attention to the first signs of drying on the tendril closest to the fruit.
Now that you know how to grow watermelons at home, there are no more excuses not to enjoy this juicy fruit in the summer!
