Let’s get started!

1. Choose the Right Seeds

1. Choose the Right Seeds

First things first, pick the right watermelon seeds. Go for varieties known for their size and flavor.

You can find these at your local garden store or order online. Look for seeds labeled “giant” or “monster” to ensure they have the genetic potential for size.

Also, check if they’re suited to your climate. Good seeds are the foundation of your watermelon journey, so take your time picking them out.

2. Prepare Your Soil

Great watermelons need great soil. Make sure your garden soil is rich in nutrients.

You could mix in compost or organic matter to boost fertility. The soil should be well-drained because waterlogged roots aren’t happy roots.

Aim for a slightly acidic pH level, around 6 to 6.8, for optimal growth. A soil test kit can help you out with that.

3. Start Seeds Indoors

3. Start Seeds Indoors

Get a head start by planting seeds indoors about 4 weeks before the last frost date in your area. Use small pots filled with seed-starting mix.

Plant each seed about an inch deep and water them well. Keep them in a warm, sunny spot or under grow lights.

This gives your seedlings a strong start and helps them get a jump on the growing season.

4. Transplant Carefully

Once the danger of frost has passed and your seedlings have grown strong, it’s time to move them outdoors. Transplant them carefully to avoid shocking the young plants.

Space them about 2-3 feet apart in rows that are 6-8 feet apart to give them plenty of room to sprawl. Water the holes well before placing the seedlings in their new home.

5. Water Wisely

5. Water Wisely

Watermelons love water, but they don’t like being soggy. Keep the soil consistently moist but not drenched.

Deep, infrequent watering encourages the roots to grow deep and strong. Water at the base and avoid getting the leaves wet to prevent disease.

Mulch around the plants can help retain moisture and keep weeds at bay.

6. Feed Your Plants

Like all giants, big watermelons need lots of food. Use a balanced fertilizer when planting and then switch to a low-nitrogen, high-phosphorus, and potassium formula once the plants start flowering.

Too much nitrogen can lead to lots of leaves but not much fruit. Follow the instructions on your fertilizer for the best results.

7. Harvest with Care

Patience is key when waiting for your watermelons to ripen. They need around 80-90 days to mature.

You’ll know they’re ready when the bottom turns a creamy yellow and they sound hollow when you tap them. Cut them off the vine with a sharp knife or pruners.

Handle them gently to avoid bruising these big beauties.
