Growing sweet potatoes at home is a rewarding experience, offering you a bountiful harvest of delicious, nutritious tubers. One of the easiest and most effective ways to grow sweet potatoes is by starting slips, which are the shoots that grow from the sweet potato. These slips, once rooted and planted, will grow into full-fledged sweet potato vines, producing a crop that you can enjoy all year round.
Starting sweet potato slips requires minimal effort, and it’s a great way to grow these nutritious vegetables in your own garden or even indoors. In this comprehensive guide, we will walk you through the process of starting slips from sweet potatoes, ensuring you have a successful crop come harvest time. Whether you’re a first-time gardener or an experienced one looking for new tips, this article will provide you with all the necessary steps to get started.
What Are Sweet Potato Slips?
Before diving into the steps of starting slips from sweet potatoes, it’s important to understand what slips are. Slips are the young shoots that sprout from a mature sweet potato when exposed to the right conditions. These shoots grow into vines, and when they’re planted in soil, they will develop into sweet potato plants that produce edible tubers beneath the ground.
The process of growing sweet potato slips involves encouraging the sweet potato to sprout in water or soil, then removing the slips once they reach a certain size and allowing them to root before planting them into the garden or larger containers.
Why Start Slips from Sweet Potatoes?
Starting slips from sweet potatoes is an excellent method for growing these crops, as it eliminates the need to purchase seed potatoes or expensive starts. It’s also an environmentally friendly approach to gardening, allowing you to reuse a simple kitchen vegetable to start a whole new crop.
Here are some reasons to start slips from sweet potatoes:
- Cost-Effective: No need to buy sweet potato seeds or expensive starts—just use a healthy, store-bought sweet potato.
- No Special Equipment Needed: All you need are a few household items, like water, a jar, and a sunny windowsill.
- Healthy Plants: By growing your own slips, you have control over the growing conditions, ensuring a healthier, more robust crop.
- Sustainability: Growing sweet potato slips is an eco-friendly gardening practice that reduces waste.
Step-by-Step Guide to Starting Slips from Sweet Potatoes
Step 1: Select the Right Sweet Potato
The first step in starting slips is choosing a healthy sweet potato. Ideally, you’ll want to select a firm, blemish-free sweet potato. Choose a variety that suits your climate and growing conditions, as there are many types, such as orange-fleshed, white, and purple sweet potatoes.
Look for a sweet potato that is free from damage and disease, as this will help ensure a good crop later on. A medium-sized sweet potato is typically best for starting slips, as it will provide plenty of shoots.
Step 2: Prepare Your Sweet Potato for Sprouting
Once you’ve selected your sweet potato, it’s time to prepare it for sprouting. The most common way to start slips is by using water to encourage the sweet potato to grow shoots.
- Place the Sweet Potato in Water: Submerge the bottom (the end where the roots are) of the sweet potato in a jar or container of water. The top of the sweet potato should remain above the water line, so only the bottom is submerged.
- Stabilize the Sweet Potato: To keep the sweet potato suspended in the water, insert toothpicks or skewers around the middle of the sweet potato. This will help support it in the container and prevent it from falling into the water.
Ensure that the sweet potato is in a warm, sunny location where it can get plenty of light. A windowsill is often the best place for this, as the sweet potato needs warmth to sprout.
Step 3: Wait for Slips to Form
After setting up the sweet potato in water, it may take anywhere from two to four weeks for the slips to start growing. You’ll notice small roots beginning to form at the bottom of the sweet potato, followed by small green shoots sprouting from the top. These green shoots are the slips.
During this time, make sure the water level stays consistent. You’ll need to top it up occasionally to ensure the bottom of the sweet potato remains submerged.
- Maintain Temperature and Light: Sweet potatoes thrive in warmth, so try to keep the room temperature between 70-80°F (21-27°C). The slips also need at least 6-8 hours of indirect sunlight per day to grow properly.
Step 4: Remove the Slips
As the sweet potato begins to sprout, you’ll see slips growing from the top of the tuber. These slips are typically ready to be harvested once they are 4-6 inches tall. When the slips are long enough, twist them gently off the sweet potato by gripping the base of the sprout. Don’t pull too hard, as this can damage the root system of the slip.
- Be Gentle: Make sure to handle the slips with care, as they are delicate and can easily break.
- Leave the Tubers: After removing the slips, the sweet potato can continue to produce new slips, so you can leave it in the water if you want to harvest more.
Step 5: Root the Slips
Once you’ve removed the slips from the sweet potato, you need to let them develop roots before planting them in the garden or containers.
- Place Slips in Water: After removing the slips, place them in a jar or glass of water. Make sure the bottom half of the slip is submerged in water. Leave them in a bright spot with indirect sunlight, and within a few days, you should see small roots beginning to form.
- Wait for Strong Roots: Allow the slips to root for about 1-2 weeks until you see strong, healthy roots. At this point, the slips are ready to be transplanted into soil.
Step 6: Plant the Slips in the Garden or Containers
Once your slips have developed strong roots, it’s time to plant them.
- Choose a Planting Site: Sweet potatoes need well-draining soil and a full-sun location to grow best. Make sure your planting site receives at least 6-8 hours of sunlight per day.
- Prepare the Soil: Loosen the soil and add organic matter such as compost to help the sweet potatoes grow. Sweet potatoes prefer slightly acidic soil with a pH of 5.8-6.2.
- Plant the Slips: Dig a small hole about 3-4 inches deep and place the rooted slip in the hole. Fill the hole with soil, covering the slip up to its leaves. Space the slips about 12-18 inches apart to give the plants room to grow.
- Water the Plants: After planting, water the slips gently to settle the soil around their roots. Keep the soil moist but not soggy as the plants establish themselves.
Step 7: Care for the Growing Sweet Potatoes
Once the slips are in the ground, they’ll need proper care to grow successfully.
- Fertilize: Use a balanced fertilizer to feed the plants, especially in the early stages of growth. Be sure to follow the manufacturer’s recommendations to avoid overfeeding.
- Water Regularly: Sweet potatoes need consistent moisture, especially during dry periods. Water them deeply, ensuring the soil stays moist but not waterlogged.
- Control Weeds: Keep the area around the sweet potatoes free from weeds to reduce competition for nutrients and water.
Step 8: Harvest Your Sweet Potatoes
Sweet potatoes are typically ready for harvest in 90-170 days, depending on the variety. Harvest them in the fall when the vines begin to yellow and die back. Carefully dig up the tubers with a garden fork, being cautious not to damage them.
Let the sweet potatoes cure for about 10-14 days in a warm, dry location before storing them. This process helps enhance their flavor and storage life.
Conclusion
Starting slips from sweet potatoes is a simple and rewarding process that can be done right at home. Whether you’re an experienced gardener or just starting out, this method provides a cost-effective and sustainable way to grow your own sweet potatoes. With a little patience and care, you’ll have healthy sweet potato vines producing delicious, homegrown tubers ready to harvest.
