Grow Watermelons in a Sack: A DIY Guide for Small Spaces
Hey there, fellow gardening enthusiasts! Ever dreamed of growing your own juicy watermelons but thought you didn’t have the space? Well, I’m here to tell you that you absolutely can, even if you only have a small balcony or patio! The secret? Sack gardening! It’s a fantastic way to maximize your growing area and enjoy fresh, homegrown watermelons. Let’s dive into how you can make this happen.
What You’ll Need
Before we get started, let’s gather all the necessary materials. This will make the whole process smoother and more enjoyable. Trust me, being prepared is half the battle!
* A Large, Sturdy Sack: Think burlap, heavy-duty polypropylene (like a feed sack), or even a reinforced grow bag. The bigger, the better – aim for at least 20-25 gallons. This gives the watermelon roots plenty of room to spread out.
* Potting Mix: A high-quality potting mix is crucial. It should be well-draining and rich in organic matter. I like to use a mix of compost, peat moss (or coco coir), and perlite.
* Watermelon Seeds or Seedlings: Choose a variety that’s known for its smaller size and shorter growing season. Bush or dwarf varieties are ideal for sack gardening. Sugar Baby, Bush Sugar Baby, or even some icebox varieties work great.
* Slow-Release Fertilizer: This will provide your watermelon plant with a steady supply of nutrients throughout the growing season. Look for a fertilizer specifically formulated for fruits and vegetables.
* Water-Soluble Fertilizer: For an extra boost, especially during fruiting, a water-soluble fertilizer will come in handy.
* Trowel or Shovel: For mixing and transferring the potting mix.
* Watering Can or Hose: Essential for keeping your watermelon plant hydrated.
* Support Structure (Optional): Depending on the variety you choose, you might need a trellis or some other support to keep the vines off the ground.
* Gloves: To keep your hands clean and protected.
* Scissors or Utility Knife: For cutting the sack if needed.
Preparing the Sack
The first step is to get your sack ready for planting. This involves ensuring proper drainage and creating a stable base for your watermelon plant.
1. Clean the Sack: If you’re using a recycled sack, make sure it’s clean and free of any debris. Give it a good shake and wipe it down if necessary.
2. Reinforce the Sack (Optional): If your sack seems a bit flimsy, you can reinforce it by lining the inside with a heavy-duty plastic bag. Just make sure to poke plenty of drainage holes in the bottom of the bag.
3. Create Drainage Holes: This is super important! Waterlogged soil is a watermelon’s worst enemy. Use your scissors or utility knife to create several drainage holes in the bottom of the sack. I usually make about 6-8 holes, spaced evenly apart.
4. Position the Sack: Choose a sunny spot for your sack garden. Watermelons need at least 6-8 hours of direct sunlight per day. Place the sack where it will stay for the entire growing season, as it will be heavy to move once it’s filled with soil.
Filling the Sack with Potting Mix
Now comes the fun part – filling the sack with the nutrient-rich potting mix that will nourish your watermelon plant.
1. Mix the Potting Mix: In a large container or on a tarp, thoroughly mix your compost, peat moss (or coco coir), and perlite. Add the slow-release fertilizer according to the package instructions. I like to use a ratio of about 1 part compost, 1 part peat moss (or coco coir), and 1 part perlite.
2. Fill the Sack: Gradually fill the sack with the potting mix, leaving about 4-6 inches of space at the top. As you fill, gently pat down the soil to remove any air pockets.
3. Water the Soil: Once the sack is filled, thoroughly water the soil until water drains out of the drainage holes. This will help settle the soil and prepare it for planting.
Planting Your Watermelon Seeds or Seedlings
Now it’s time to introduce your watermelon plant to its new home!
1. Starting from Seed: If you’re starting from seed, sow 2-3 seeds in the center of the sack, about 1 inch deep. Cover the seeds with soil and gently water. Keep the soil consistently moist until the seeds germinate, which usually takes about 7-10 days. Once the seedlings emerge, thin them to one strong plant.
2. Planting Seedlings: If you’re using seedlings, gently remove the seedling from its container, being careful not to damage the roots. Dig a hole in the center of the sack that’s large enough to accommodate the root ball. Place the seedling in the hole and backfill with soil. Gently pat down the soil around the base of the plant.
3. Water Thoroughly: After planting, water the seedling thoroughly. This will help it establish its roots in the new soil.
Caring for Your Sack-Grown Watermelon
Now that your watermelon plant is in its sack, it’s time to provide it with the care it needs to thrive.
1. Watering: Watermelons need consistent moisture, especially during hot weather. Check the soil moisture regularly and water when the top inch of soil feels dry to the touch. Water deeply, ensuring that the water reaches the roots. Avoid overwatering, as this can lead to root rot.
2. Fertilizing: In addition to the slow-release fertilizer you added to the potting mix, you can also supplement with a water-soluble fertilizer every 2-3 weeks. Follow the package instructions for application rates. I like to use a fertilizer that’s high in phosphorus and potassium, as these nutrients are essential for fruit development.
3. Sunlight: Make sure your watermelon plant is getting at least 6-8 hours of direct sunlight per day. If you live in a particularly hot climate, you may need to provide some afternoon shade to prevent the plant from getting scorched.
4. Support: As your watermelon vine grows, it may need some support to keep the fruits off the ground. You can use a trellis, stakes, or even a sling made from old pantyhose to support the developing watermelons. This will help prevent them from rotting or getting damaged.
5. Pruning: Pruning can help improve air circulation and encourage fruit production. Remove any dead or yellowing leaves, as well as any suckers (small shoots that grow from the base of the plant). You can also pinch off the tips of the vines to encourage branching.
6. Pollination: Watermelons need to be pollinated in order to produce fruit. If you’re growing your watermelon plant indoors or in an area with limited bee activity, you may need to hand-pollinate the flowers. To do this, use a small paintbrush to transfer pollen from the male flowers to the female flowers. The female flowers have a small swelling at the base, which will eventually develop into a watermelon.
Harvesting Your Watermelon
The moment you’ve been waiting for! Harvesting your own homegrown watermelon is incredibly rewarding.
1. Check for Ripeness: Watermelons typically take about 80-90 days to mature. There are several ways to tell if a watermelon is ripe. One way is to look at the tendril closest to the fruit. If the tendril is brown and dry, the watermelon is likely ripe. Another way is to thump the watermelon. A ripe watermelon will sound hollow. You can also check the underside of the watermelon where it rests on the ground. If the spot is yellow or cream-colored, the watermelon is likely ripe.
2. Harvest Carefully: Once you’ve determined that your watermelon is ripe, use a sharp knife to cut it from the vine, leaving a few inches of stem attached. Be careful not to damage the watermelon.
3. Enjoy! Now it’s time to enjoy the fruits (or rather, the watermelon) of your labor! Slice it up and savor the sweet, juicy flavor of your homegrown watermelon.
Troubleshooting
Even with the best care, you might encounter some challenges along the way. Here are a few common problems and how to address them:
* Yellowing Leaves: This could be a sign of overwatering, underwatering, nutrient deficiency, or disease. Check the soil moisture and adjust your watering accordingly. Fertilize with a balanced fertilizer. If you suspect disease, treat with an appropriate fungicide.
* Lack of Fruit: This could be due to poor pollination, lack of sunlight, or nutrient deficiency. Hand-pollinate the flowers if necessary. Make sure your watermelon plant is getting enough sunlight. Fertilize with a fertilizer that’s high in phosphorus and potassium.
* Pests: Common watermelon pests include
