Most watermelon plants require a lot of space and quickly take over a small garden. Some varieties are described as having short vines. Those described as having bush-type plants may be disappointing.
Varieties are available that produce large or small, round or oblong, solid or striped fruit with red or yellow flesh, with seeds or seedless.
Plant when the soil is warm and all danger of frost has passed. Watermelon transplants in peat cups or plastic trays can be used, but they must be small (not yet vining) to avoid plant injury. Use transplants with seedless melons because the seed is small, expensive, and slow to germinate. For seedless melon transplants, plant the seeds with the rounded end down and the pointed end up.
Hot kaps, black plastic mulch, floating row covers, and plastic tunnels are ways to obtain earliness. Black plastic also controls weeds. You can use transplants or seeds in combination with black plastic mulch. With normal vining melons, plant several seeds in groups spaced about 6 feet apart. Thin seedlings to two plants in each group. With seedless melons, it is necessary to plant some standard melons close by to provide pollination. All watermelons are pollinated by bees and require about 45 days from pollination to maturity.
Disease problems are anthracnose, fusarium wilt, gummy stem blight, and bacterial wilt. Insect problems are striped and spotted cucumber beetles.

One month ago, watermelon production in southeast Mississippi was on track. Now, growers there have lost much of their crop to the summer’s wet weather.
Good spring weather conditions in southeast Mississippi kept watermelon production on track.
Some Mississippi watermelon producers lost crops or got a late start because of wet spring weather. But consumers should find the sweet, summer treats on shelves in time for the July 4 holiday.
