How do I grow watermelon from seed?

If you want to grow your watermelons at home, make sure you provide your plants with the finest growing conditions possible to ensure a tasty and plentiful harvest. But first, you’ll need to choose a suitable location for your plants, one with good soil, plenty of sunlight, and plenty of space.

Choose a planting spot far away from the rest of your garden to ensure your melons have enough room to flourish and to avoid them from harming nearby plants.

Once you’ve chosen a prospective growing location with enough room for 10-foot vines, make sure it gets plenty of sunlight. These plants demand full sun, eight to ten hours of direct sunlight each day or more.

Watermelons thrive in sandy, loose soil that drains well. A soil test is an excellent option if you’re unsure what type of soil you have. This will help you understand your soil, its pH, and the type of fertilizer you’ll need.

Before planting your watermelon seeds, supplement your soil with at least 1-2 inches of compost.

Sow seeds 1/2 inch deep in the soil in tiny hills or rows 36 inches apart, 7-14 days following the last frost date. Plant 6-8 seeds in the hills and 2-3 seeds every 36 inches in the rows.

Use small snips to thin the seedlings to 2-3 per hill or one plant every 36 inches in a row once they have started to grow and the actual leaves have formed, not the first leaves that came up from the seedling.

Best fertilizers for watermelons

Watermelon plants are heavy feeders and benefit from fertilization regularly. While the plants grow their stems, leaves, and canopy, we recommend using a nitrogen-rich fertilizer like diluted fish emulsion. However, after the plants begin to set fruit, you can switch to a fertilizer that contains more phosphorus and potassium to aid the fruit set.

Do watermelons need lots of water?

Like most other plants in your garden, Watermelons require 1 to 2 inches of water per week to thrive. This is especially crucial when the watermelon plants are setting and growing fruit. Water makes about 92 percent of a watermelon, so keep your plants well-watered if you want big, juicy watermelons!

What conditions do watermelons need to grow?

Watermelon plants require a long and warm growing season of at least 70 to 85 days, depending on the type, to yield sweet fruit. They grow best when the temperature is between 70 and 80 degrees Fahrenheit during the day and 65 to 70 degrees Fahrenheit at night.
