What To Know
- You can use a trellis, a fence, or even a pile of straw to help the vines grow upright.
- Growing watermelons in a cold climate may require a bit more effort, but the rewards are well worth it.
- Yes, you can grow watermelons in a pot, but you will need to choose a large pot that is at least 24 inches in diameter and 18 inches deep.
Watermelons, with their juicy red flesh and refreshing sweetness, are a summer staple. But did you know that you can grow watermelons even in colder climates? With a little extra care and attention, you can enjoy this delicious fruit no matter where you live.
1. Choose the Right Variety
The first step to growing watermelons in a cold climate is choosing the right variety. Look for varieties that are specifically bred for cooler climates, such as ‘Sugar Baby’, ‘Bush Sugar Baby’, or ‘Early Moonbeam’. These varieties have a shorter growing season and are more likely to produce fruit before the cold weather sets in.
2. Start Seeds Indoors
To get a head start on the growing season, start your watermelon seeds indoors 4-6 weeks before the last spring frost. Sow the seeds 1/2 inch deep in a peat pot filled with seed-starting mix. Keep the pots warm and moist, and transplant the seedlings outdoors when they have two sets of true leaves.
3. Prepare the Soil
Watermelons prefer well-drained, sandy soil with a pH between 6.0 and 6.8. If your soil is not ideal, you can amend it with compost or fertilizer to improve its structure and fertility.
4. Plant the Seedlings
When the soil temperature reaches 70°F (21°C), it’s time to plant the watermelon seedlings outdoors. Space the plants 3-4 feet apart in rows that are 6-8 feet apart. Water the plants deeply after planting.
5. Provide Support
Watermelon vines can grow quite long, so it’s important to provide them with support. You can use a trellis, a fence, or even a pile of straw to help the vines grow upright.
6. Water and Fertilize Regularly
Watermelons need about 1 inch of water per week. Water the plants deeply, but not so much that the soil becomes waterlogged. Fertilize the plants every few weeks with a balanced fertilizer.
7. Protect from Pests and Diseases
Watermelons are susceptible to a variety of pests and diseases, including aphids, cucumber beetles, and powdery mildew. To protect your plants, use organic pest control methods, such as insecticidal soap or neem oil.
8. Harvest the Watermelons
Watermelons are ready to harvest when the rind is hard and the bottom of the fruit has turned yellow. Cut the melons from the vine with a sharp knife.
Tips for Growing Watermelons in a Cold Climate
- Use black plastic mulch to warm the soil and help retain moisture.
- Plant your watermelons in a sunny spot that receives at least 8 hours of sunlight per day.
- Pinch off the tips of the vines when they reach 4-5 feet long to encourage more fruit production.
- Hand-pollinate the flowers to ensure fruit set.
- Cover the plants with a floating row cover if a frost is expected.
