Watermelon plants are annual vines that produce large, sweet fruits. They have large, lobed leaves and long, twining stems. The flowers are yellow and the fruits can range in size from a few pounds to over 50 pounds. Watermelons require lots of sunshine, warm temperatures, and well-drained soil. They should be planted in full sun and watered regularly. Fertilizer may be added to the soil to improve growth.

Planning Your Garden With Watermelon

As you plan your garden, it's important to think about the spacing, size, light, and nutrient requirements of all of your plant and how they'll grow together.

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.

By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.
