Watermelons are one of the most popular fruits in the world, and for good reason. These juicy, sweet fruits are healthy, delicious, and a joy to grow. If you’re interested in growing your own watermelon plant at home, check out this article for everything you need to know about how to grow watermelon plants from seed.

There are many ways to grow watermelon plants at home. The most common method is to start from seed. This method takes longer than purchasing a seedling, but it also gives you more control over the final product. Watermelons are not very picky about soil type or pH level, so you can grow them in almost any kind of soil that drains well. However, they prefer sandy loam soils that are well-drained and full of organic matter. You should also add plenty of compost or manure to your soil before planting, as this will help the plant get off to a good start.

You’ll want to space your seeds about 12 inches apart when planting your watermelon plants in the ground. If using an elevated trellis system like a teepee structure or an arbor, then space accordingly depending on how many plants you want to grow per structure. Watermelons need 6-8 hours of sunlight each day in order to produce fruit. Keep them well watered throughout their growth as well—they require lots of water.

Select the right planting season

The best time to plant a watermelon is during the months of June and August. This is when the weather is warm and dry, which is perfect for growing watermelons. If you live in a cold climate area, it may be possible to grow them outside during early spring (March or April), but they would need protection from frosty nights.

Watermelons grow best when their roots are planted in sandy or loamy soil that drains well. The soil should also be rich with organic matter such as compost or manure. If your garden has poor drainage, try improving it before planting by adding stones or gravel over top of your existing soil. Watermelons do not like wet feet.

Prepare proper soil for Watermelon cultivation

  • Select an area that gets at least six hours of sunlight each day.
  • Soil pH should be 6.5 to 7.0 for optimal growth and production, but it can also be as low as 5.5 and still produce a crop if you have very sandy soil.
  • Ensure that the soil is well-drained and loose – watermelons do not like wet or compacted soils. If your garden has clay soil, consider adding compost to loosen up the ground before planting your watermelon seeds or seedlings (if growing from seed).
  • The soil must be fertile; add manure or compost during planting season (March through June) to increase fertility levels in your garden, especially if you’re starting with poor-quality dirt like mine was.

Place your seedlings in a good condition

Watermelon seedlings should be planted in a warm and sunny place. You should also make sure that the soil is well-drained. The ideal temperature for watermelon plants to grow is between 60 to 75 degrees Fahrenheit (16-24 C).

The watermelon seedlings must be planted at a depth of 3 inches and spaced 3 feet apart from each other.

Planting Watermelon

Growing watermelon plants is easy and fun, but it’s important to start with the right seeds. Here are some tips for planting watermelon seeds:

  • Start with a seedling or small plant. Watermelon plants can be grown from seed, but they are quicker and more productive when started indoors as seedlings.
  • Prepare the soil well before planting your seeds. Watermelons do best in full sun, so choose a sunny spot in your garden that has plenty of room for them to spread out once they begin producing fruit. You should also prepare the soil by loosening it up with a tiller or shovel, then add some compost before planting your seeds so that you have good soil for growing healthy plants later on.
  • Planting watermelon seeds directly into earth tends to produce better yields than growing them in containers does because there’s less stress on the plant from being transplanted into pots (which can cause it to die). However, if you live somewhere where space is limited then container gardening may work better for you since this way you don’t need as much land space needed for growing regular-sized plants either.

Watering and Mulching

The first rule of watering a watermelon plant is to do it regularly. The second rule of watering a watermelon plant is not to overdo it. Watering your plant well before the soil dries out will help prevent diseases and keep roots moist, but if you’re constantly drowning your plants in water they’ll never have time to dry out and mature properly. When in doubt, wait until you see signs of wilting before adding more water—too much moisture can kill your plants just as easily as too little.

The best way to ensure that your soil remains cool and moist through summer’s heat is mulch: cover the ground around the base of your vine with an inch or two (2-5 cm) of organic materials such as grass clippings or shredded bark chips so that no sunlight reaches bare earth directly beneath where leaves meet stem. Keep this area covered throughout summer months so that roots don’t dry out in direct sunlight during hot days; remember: if there’s one thing worse for a vegetable than too much sun, it’s not enough sun.


  • Fertilize the soil before planting. When you are preparing to plant, use a balanced fertilizer that is high in nitrogen but low in phosphorus (NPK ratio of 5-10-5 or 10-10-10). The best time to apply this kind of fertilizer is right after you have tilled and turned over your garden bed.
  • Fertilize the soil after planting – Watermelon plants require a lot of nutrients during their first year and again at flowering time, so it’s important to fertilize regularly with a balanced organic all purpose fertilizer such as fish emulsion or liquid seaweed throughout their development stage until they reach maturity at about one foot tall (30 cm). Apply approximately 1 gallon per plant every two weeks during summer months when temperatures are above 75 degrees Fahrenheit (24 degrees Celsius), more often if needed by checking leaf coloration – pale yellow indicates lack of nutrients while deep green indicates an ample supply. To encourage strong root growth at transplanting, add some composted manure into each hole before backfilling them with soil mixture from kitchen compost bins; use about 1 cup per plant depending on how large you’ve planted them.

Managing Weed, Pest, and Disease

  • Weed: Weed control is very important for all gardeners. It is recommended to use some herbicides to control weeds before planting watermelon, especially if you are growing the plant in a greenhouse or enclosed area, where it is not easily accessible for hoeing and hand-weeding. After the seeds have germinated and seedlings have emerged from soil, they can be sprayed with chemicals according to label instructions such as glyphosate or other similar chemicals that are effective at controlling broadleaf weeds like dandelions and chickweed. Remember that these chemicals should be applied with caution since they may kill desirable plants if used improperly.
  • Pests: There are many types of insects that destroy watermelons including aphids (greenfly), spider mites(red spider), whiteflies(mealybug), stinkbugs(bark bugs), scale insects(cushion scale). You can identify these pests by their appearance or by their damage symptoms on leaves

Growing watermelon at home is the best way to get fresh and delicious watermelons.

Watermelon is a fruit that is grown in home gardens. It’s a great source of water and nutrients, providing both vitamin A and C, vitamin B6, and potassium. The best thing about growing watermelon at home is that you can get fresh and delicious watermelons all year long.
