Watermelon: How to Grow and When to Plant in Your Backyard or Patio Garden!

Watermelon blog post
This sweet, juicy, fruit is one of our favorite summer treats. Watermelons can be difficult to grow (and protect from mice and other pests) and are time-consuming, but they are extremely rewarding at the end!

How to Grow:

Sow seeds indoors 2 weeks before transplanting to get a head start on your season. You can begin plant outdoors 2 weeks after your last spring frost and throughout the summer up to 16 weeks before your first fall frost. You can see specific dates for your location using our FREE iOS, Android, and Universal Web App.

Sow 1 seed per square foot about 1/2 inch deep. You can can place a trellis by the squares for the vines to help to save space and grow vertically. Make sure to plant in a space that has full sun. Take care to notice what plants are around the area as well, see the companion plant section below. It will take approximately 7-14 days for your seeds to sprout. Provide your watermelon plant with approximately 1-2 inches of water weekly until the melons are almost ripe then back off significantly on watering to improve sweetness.

Companion Plants:

Companion planting is a vital part of organic gardening. Companion plants assist in the growth of others by attracting beneficial insects, repelling pests, or providing nutrients, shade, or support. There are also plants that do not like being next to each other. Some plants get too tall and can provide too much shade for your plant. Sometimes certain plants attract the same pests, so it is important to try and separate these. Herbs are especially great companion plants because they help to repel pests from your other plants!

You will begin to be able to harvest your cucumbers approximately 90-120 days from first sprout. When the watermelons start to give off a strong melon scent, that means it’s getting close. The tendrils closest to the fruit will also turn brown. The stem should snap off easily if it ready to harvest.

How to Prepare:

You can eat watermelon directly from the garden or chill it the refrigerator. Eat it by itself, or add it to a fresh salad.
