Growing watermelon indoors is a great way to ensure that you have fresh watermelons all year round, even if you live in an area where the soil is not suitable for growing. Watermelons are also relatively easy to grow indoors and they can give you a lot of fresh fruit during their growing season.
The first thing that you need to do when growing watermelons indoors is to make sure that your plant has enough sunlight each day. Watermelons need at least 6 hours of direct sunlight per day in order for them to grow properly. If this isn’t possible, then you can use artificial lights or grow them under fluorescent lights instead.
To grow a watermelon plant indoors, start by preparing the seed starting mix. For this purpose, it’s best if you use a commercial potting soil mix rather than just using regular soil from outside because it will have better drainage properties and won’t compact easily when watered heavily which could cause root rot issues down the road.
Mix equal parts sand and compost into the potting soil before adding some organic fertilizer into it too so that your plants get all of their nutritional requirements met as well as being able to withstand any pests or diseases that might come along later on down the line too.
Growing watermelons indoors is a great way to engage your family in the garden or have fun on your own. Make sure you have the right variety of watermelon, plant at the right time, choose fertile soil, and provide consistent but not overwatering.

Plant closely to maximize yield
Planting watermelons closely will maximize yield, but you must be careful about how close to the vines you place each seed.
Planting the seeds too close together can lead to disease and other issues. If you plant them too far apart, they won’t produce as much fruit as they could have if they were planted closer to each other.
Plant in fertile soil
Good soil fertility is key to growing healthy plants.
Soil fertility is measured by the amount of nutrients in your soil, which ultimately affects how well your plant can grow. You can test your soil’s nutrient levels with a soil test kit or by having it tested at a local garden center. Most importantly, you will want to add fertilizer to improve the quality and vigor of your soil before planting your watermelon seedlings outdoors.
Plant at the right time.
Plant in the early spring or late summer. To grow a watermelon indoors, you’ll need to plant the seedlings (young plants) before the first frost of your area. If you live in an area where there is little danger of frost, then they can be planted around February or March. Otherwise, wait until May or June when you’re sure that temperatures will remain above 50 degrees Fahrenheit during the day and below 60 degrees at night.
Once planted, watermelons like plenty of sunshine but not too much heat. Watermelons are heat-loving plants and will do best if kept warm; temperatures over 80 degrees can cause them to overheat and die from dehydration. A south-facing windowsill would be ideal for growing your watermelon indoors since it gets lots of sunlight exposure all day long without being too hot. A pot that has drainage holes is also necessary because this type of container allows excess water to drain away instead of staying inside where it could cause root rot (which would kill your plant). Make sure that the pot has enough room for its roots by choosing one with a large enough diameter opening; otherwise its roots might become constricted as they try to escape through such small openings which may lead them back into growth problems later on down the road.
Water consistently but don’t overwater.
Watermelon plants need to be kept consistently moist, but not too moist. Water constantly; do not let the soil start to dry out between watering. However, if your watermelon plant feels like it’s in danger of getting too soggy and rotting, take care to allow the soil to become more dry between watering sessions. This will promote healthy roots and help prevent disease problems with your watermelon plant.
Balance temperature for optimal growth.
Watermelons require a balance of temperature to grow successfully. Too much heat or too little can hinder your watermelon plants’ growth and yield, while the right temperatures will promote optimal results.
- Germination: A steady temperature between 70 and 80 degrees Fahrenheit is best for seed germination, which happens in about three days. If you have a heating mat, use it during this time–but don’t get it so hot that the seeds dry out prematurely.
- Plant Growth: Once that initial sprout appears, you can lower your thermostat to about 70 degrees or keep it on an automatic timer for eight hours of warm light per day before switching back to 18 hours of cool light per day (usually recommended). Keep in mind that this is just a general guideline; some varieties may require less or more time under lights than others do–check with your supplier if there’s any doubt.
Growing watermelons inside can be a fun and engaging activity you can do with your family or alone
Growing watermelons indoors is a fun and engaging activity you can do with your family or alone. The following steps can help you get started:
- Select the right watermelon seeds for your needs and space.
- Prepare the soil in your indoor garden bed by digging it out, adding fertilizer, mixing it together, then re-digging and raking it flat so it’s ready to receive watermelons when they are ready to be planted.
- Plant your seedlings in individual pots filled with potting mix until their leaves are about 2 inches above ground level before transplanting them into larger containers or an indoor garden bed where they will spend most of their life growing until harvest time comes around again.
