How to fertilize your watermelon plant.

If you have a vegetable garden, it is a great idea to grow watermelon seeds as they are easy to grow and delicious on sunny afternoons.

Keep in mind that watermelon seeds need at least 80 days to grow and warm weather to germinate. Make sure the soil is at least 21° Celsius or warmer at planting time. Watermelon seeds must be sown 2.50 centimetres deep; don’t forget to keep them well-watered until germination.

In tropical countries, such as Malaysia, you can grow watermelon seeds all year long. Even in colder climates, you can start early by covering the plant area with plastic to warm up the soil or start seeds indoors before transplanting them in the garden.

Plant 3 watermelon seeds 5 or 7 centimetres apart and sparingly to achieve the best plants. It is best to sow seeds 1.20 centimetres deep. Choose a sunny area to enhance germination. The site should be warm day and night, ideally at least 27° Celsius.

To get better results, you need to know how to fertilize your watermelon seeds. Follow this guideline to doing it correctly.

Watermelon Seeds Fertilizer

1. When to fertilize.

Please note there is no set watermelon fertilizer program. Professional gardeners decide when to add fertilizer by analyzing the soil condition and a seed’s phase. It is essential to see whether it is an emergent seedling, or it is already in bloom.

It is essential to realize that each phase has different nutritional requirements.

Use nitrogen-based fertilizer on your watermelon plants. When the watermelon seeds start to flower, you should switch to a phosphorus and potassium-based fertilizer. Keep in mind that watermelon needs sufficient potassium and phosphorus to ensure excellent production.

2. How to fertilize watermelon seeds at planting.

If you are growing watermelon seeds in your vegetable garden, it is a terrific idea to add fertilizer to the soil when planting. Another excellent method is to apply a fertilizer solution when you water.

It is vital to fertilize when fruit begins to set. You can also add a 1/4 pound of fertiliser next to each plant.

3. Do I need to fertilize watermelon seeds?

Yes, you do.

Watermelon is a member of the Cucurbitaceae family, and to grow it needs many nutrients, especially phosphorus, potassium and nitrogen. Remember that once the plants begin to flower, you need to change to a fertilizer with less nitrogen to boost flowers and fruit.

An excellent option is a seaweed-based fertilizer.

Professional gardeners agree that too much nitrogen fertilizer can prevent enough fruiting while enhancing too much vine growth.

4. Do I need a soil test?

It is best to use a soil test to see what fertilizer is required. If you don’t have one, we recommend applying 5-10-10 fertilizer at 30 pounds per 1,000 square feet before planting.

Apply next to each plant a 34-0-0 at 1 pound per 100 feet of row. You can use calcium nitrate or 15.5-0-0 at 2 pounds per 100 feet of row.

It would help if you fertilized next to each plant once the fruit starts to grow.

5. Which type of fertilizer is better for watermelon seeds?

There are two types of fertilizer: granular and water-soluble.

If you choose a granular fertilizer, it is a good idea to select a balanced one like 10-10-10 or 5-5-5. Please note that having the same three numbers means they have the same amount of nitrogen, potassium and phosphate.

Even though most granular fertilizers are applied at a rate of 1 1/2 pounds per 100 square, we strongly suggest following the manufacturer’s directions for the proper dosage. It is best to avoid contact between the fertilizer and the plant as this can lead the plant to burn.

A water-soluble fertilizer is also a terrific choice. Most gardeners usually use a one-gallon jug to mix the fertilizer and then apply it at the main stem’s base. Apply fertilizer after the blossom appears, and the fruit is beginning to grow. Doing this allows the plant to produce high-quality fruit.

The Bottom Line

Watermelon seeds are a fantastic addition to your vegetable garden as they are easy to grow and delicious to eat. Besides adding fertilizer, it is crucial to give the watermelon plant water.

Plentiful water produces the most enormous, sweetest and juiciest fruit. Avoid overwatering. The top 3 to 5 centimetres should dry out between watering. For more information, feel free to get in touch with us.
