Can you Grow Watermelon in a Pot?

It grows rapidly and requires plenty of water when you sow fresh seeds in a pot. Make sure to use a large container of size 5-gallon and has enough drainage in it.

Soil

Melons need rich, loamy and well-drained soil to promote plant growth. Soil pH should be 6.0-6.8. It grows well in the summer season by producing prolific leaves, trailing vines, and fruits.  Fruits grow more quickly in light sandy soils than heavy clay soils.

Temperature

Melons love the heat and seeds will germinate in 10 days when the temperature is 65 F. Best temperature to grow melons is 70 F to 90 F. Avoid growing melons if the temperature is below 50 F which may cause fruits to lose its flavor.

Water

Watermelons require plenty of water. Keep the soil moist and water must be drained from the bottom. You need to water the melon plant regularly. Once the fruit matures and starts swelling reduce the water supply. To get sweet melons, avoid over watering and under watering as it results in mildew.

Pollination

Generally, plants cannot produce fruits without pollination as it is the essential step in producing seeds. Pollination is the process in which pollen can be transferred to the female reproductive organs of the plant. The plant has both male and female flowers and can be pollinated without the help of other plants. When pollination of flowers is done, fruits may appear approximately after 40 days.

  • High intake of calcium encourages the leaf production and in maintaining fruit firmness with minimal cracking.

Fertilizers        

Use nitrogen-based fertilizer for better growth. When plants begin to flower, feed the plant with phosphorus and potassium. Well, rotted horse, rabbit or cow manure improves soil texture and provides nutrients constantly to the melon plants. You can also add mulch to retain soil moisture.
