Growing watermelons in containers is a great way for urban gardeners with limited space to enjoy fresh, homegrown melons. Here are some key tips for successfully growing watermelons in pots:
Choosing the Right Variety
Select a compact or bush-type watermelon variety that is well-suited for container growing, such as:
- Sugar Baby: Produces 8-10 lb round fruits, perfect for small spaces
- Yellow Baby: Hybrid with thin rind and sweet yellow flesh, similar shape to classic watermelons
- Mini Love: High-yielding hybrid with 3-6 lb round fruits and deep red flesh
Container Size and Material
Use a large container that is at least 18 inches deep, such as a 5-gallon bucket or plastic storage bin. The container should have drainage holes in the bottom. Avoid dark colored containers which can absorb too much heat.
Soil and Planting
Fill the container with a well-draining potting mix amended with compost. Plant 2-3 seeds 1 inch deep, spacing them evenly. Thin to the strongest seedling after they sprout.
Trellising for Support
Watermelons are vining plants that need support as they grow. Install a sturdy trellis, cage or stake in the container to train the vines vertically. This saves space and keeps the fruit off the ground.
Watering and Fertilizing
Watermelons require consistent moisture. Water whenever the top inch of soil is dry, about 1-2 inches per week. Use a balanced liquid fertilizer every 2-3 weeks during the growing season.
Harvesting
Watermelons are ready to harvest when the underside turns creamy yellow and the tendril near the stem dries up. Use a sharp knife to cut the fruit from the vine, leaving a short stem attached.With the right variety, ample container size, and proper care, you can grow a bountiful crop of watermelons in even the smallest urban garden! Trellising is key for maximizing space. Enjoy your homegrown watermelons fresh or in tasty summer recipes.
