DIY Vertical Sweet Potato Tower: Grow More in Less Space!
Hey there, fellow gardeners! Are you dreaming of a bountiful sweet potato harvest but short on garden space? Well, I’ve got just the project for you: a DIY vertical sweet potato tower! This ingenious method allows you to grow a surprising amount of sweet potatoes in a small footprint, making it perfect for urban gardens, patios, or even balconies. Plus, it’s a fun and rewarding project that’s sure to impress your friends and neighbors. Let’s get started!
What You’ll Need:
Before we dive in, let’s gather all the necessary materials. This will make the building process much smoother.
* Hardware Cloth (1/2 inch mesh): This will form the structure of our tower. The amount you need will depend on the desired height and diameter of your tower. I recommend at least 4 feet wide by 6 feet long.
* Heavy-Duty Zip Ties: These will be used to secure the hardware cloth together. Get a good supply – you’ll need more than you think!
* Landscape Fabric: This will line the inside of the tower, preventing soil from escaping.
* Potting Soil: A high-quality potting mix is crucial for healthy sweet potato growth. Avoid using garden soil, as it can compact and hinder root development.
* Compost: Adding compost to your potting mix will provide essential nutrients and improve drainage.
* Sweet Potato Slips: These are the sprouts that grow from sweet potatoes and will become your plants. You can purchase them online or at your local garden center. Alternatively, you can sprout your own from a sweet potato (more on that later!).
* Watering Can or Hose: For keeping your sweet potato tower well-watered.
* Gloves: To protect your hands from the hardware cloth and soil.
* Wire Cutters or Tin Snips: For cutting the hardware cloth.
* Measuring Tape: To ensure accurate measurements.
* Optional: Wooden stakes or rebar for added support (especially for taller towers).
Building the Tower: Step-by-Step
Okay, let’s get our hands dirty and build this tower!
1. Cut the Hardware Cloth: Using your wire cutters or tin snips, cut the hardware cloth to the desired size. Remember, I suggested 4 feet wide by 6 feet long, but you can adjust this based on your space and desired tower size. The 4-foot width will become the circumference of your tower.
2. Form the Cylinder: Carefully roll the hardware cloth into a cylinder shape. Overlap the edges by a few inches. This overlap is where we’ll secure the cylinder.
3. Secure the Cylinder: Using your zip ties, attach the overlapping edges of the hardware cloth together. Start at the top and bottom, and then add zip ties every few inches along the seam. Make sure the zip ties are tight and secure. Trim off any excess zip tie length.
4. Line the Tower with Landscape Fabric: Now, we need to line the inside of the hardware cloth cylinder with landscape fabric. This will prevent the soil from washing out. Cut a piece of landscape fabric that’s slightly larger than the inside of the cylinder.
5. Attach the Landscape Fabric: Carefully insert the landscape fabric into the cylinder. Fold the top edge of the fabric over the top of the hardware cloth and secure it with zip ties. Repeat this process along the entire top edge of the cylinder. You can also secure the landscape fabric to the hardware cloth along the sides and bottom, but it’s not strictly necessary.
6. Position the Tower: Choose a sunny location for your sweet potato tower. Sweet potatoes need at least 6-8 hours of sunlight per day. Place the tower in its final location before filling it with soil, as it will become very heavy.
7. Add Support (Optional): If you’re building a tall tower, you might want to add some support to prevent it from tipping over. You can insert wooden stakes or rebar into the ground around the tower and attach them to the hardware cloth with zip ties.
8. Prepare the Soil Mix: In a large container or wheelbarrow, mix your potting soil and compost. I recommend a ratio of about 2 parts potting soil to 1 part compost. This will provide a well-draining and nutrient-rich growing medium for your sweet potatoes.
9. Fill the Tower with Soil: Now, it’s time to fill the tower with your soil mix. Start by adding a few inches of soil to the bottom of the tower.
10. Plant the Sweet Potato Slips: This is the fun part! Gently dig small holes in the soil, spacing them about 12-18 inches apart around the tower. Carefully remove the sweet potato slips from their containers and plant them in the holes. Make sure the roots are covered with soil, but leave the leaves exposed.
11. Continue Filling and Planting: Continue adding soil and planting sweet potato slips until the tower is full. You can plant slips all the way up the sides of the tower, creating a lush, green wall.
12. Water Thoroughly: After planting, water the tower thoroughly to settle the soil and hydrate the sweet potato slips.
Sprouting Your Own Sweet Potato Slips (If You Don’t Want to Buy Them)
If you’re feeling adventurous, you can sprout your own sweet potato slips from a sweet potato you bought at the grocery store. Here’s how:
1. Choose a Healthy Sweet Potato: Select a firm, healthy sweet potato that is free from blemishes or soft spots.
2. Suspend the Sweet Potato: There are two main methods for sprouting sweet potatoes:
* Water Method: Insert toothpicks around the middle of the sweet potato and suspend it over a jar or glass filled with water. The bottom half of the sweet potato should be submerged in water.
* Soil Method: Bury the sweet potato halfway in a container filled with moist potting soil.
3. Place in a Warm, Sunny Location: Place the sweet potato in a warm, sunny location.
4. Wait for Sprouts: It will take several weeks for sprouts (slips) to emerge from the sweet potato. Keep the water level consistent (for the water method) and the soil moist (for the soil method).
5. Harvest the Slips: Once the slips are about 6-8 inches long, carefully twist or cut them off the sweet potato.
6. Root the Slips (Optional): You can root the slips in water before planting them in the tower. Place the cut end of the slip in a glass of water and wait for roots to develop. This will give the slips a head start.
7. Plant the Slips: Plant the slips in your sweet potato tower as described above.
Caring for Your Sweet Potato Tower
Now that your sweet potato tower is built and planted, it’s important to provide proper care to ensure a successful harvest.
* Watering: Sweet potatoes need consistent moisture, especially during hot weather. Water the tower regularly, making sure the soil stays moist but not waterlogged. Check the soil moisture by sticking your finger into the soil. If it feels dry, it’s time to water.
* Fertilizing: Sweet potatoes are heavy feeders, so they benefit from regular fertilization. Use a balanced fertilizer or a fertilizer specifically formulated for root vegetables. Follow the instructions on the fertilizer package. I like to use a liquid seaweed fertilizer every few weeks.
* Sunlight: Make sure your sweet potato tower receives at least 6-8 hours of sunlight per day.
* Pest Control: Keep an eye out for pests such as aphids, flea beetles, and sweet potato weevils. If you notice any pests, take action immediately. You can use insecticidal soap, neem oil, or other organic pest control methods.
* Weeding: Remove any weeds that grow in the tower. Weeds can compete with your sweet potatoes for nutrients and water.
* Pruning (Optional): While not essential, you can prune the vines of your sweet potato plants to encourage bushier growth and more sweet potato production. Simply trim back the ends of the vines.
Harvesting Your Sweet Potatoes
The moment we’ve all been waiting for! Sweet potatoes are typically ready to harvest in the fall, about 90-120 days after planting. Here are some signs that your sweet potatoes are ready to harvest:
* The Vines Start to Yellow and Die Back: This is a natural sign that the plant is nearing the end of its life cycle.
* Test Dig: Carefully dig around the base of one of the plants to check the size of the sweet potatoes. If they are a good size and have a smooth skin, they are likely ready to harvest.
To harvest your sweet potatoes, gently loosen the soil around the base of the tower. Then, carefully pull the vines out of the tower, being careful not to damage the sweet potatoes
