Sweet potatoes are a delicious and nutritious vegetable that is easy to grow in your own garden. One of the best ways to get started is to cut slips from existing sweet potatoes. This is a simple process that can be done in just a few minutes.
To start, you will need to select a few healthy sweet potatoes. Look for potatoes that are free of any bruises or blemishes. Once you have selected your potatoes, you will need to cut them into slips. A slip is simply a piece of the potato that has a bud or sprout on it. To make a slip, cut a piece of potato about 2 inches long and 1 inch wide. Make sure that the slip has at least one bud or sprout on it.
Once you have cut your slips, you will need to plant them in a well-drained soil. You can plant the slips directly in the ground or in containers. If you are planting the slips in the ground, be sure to space them about 12 inches apart. If you are planting the slips in containers, be sure to use a potting mix that is well-drained. Keep the soil moist and the plants will soon begin to grow.
Selecting the Right Sweet Potato for Slips
When choosing sweet potatoes for slips, it’s crucial to consider factors that will impact the success of your planting: variety, health of the root, and storage conditions.
Variety Selection:
| Factors to Consider | Recommended Varieties |
|---|---|
| Disease Resistance | Beauregard, Covington, Hernandez |
| Slip Production Potential | Centennial, Jewel, Porto Rico |
| Market Demand | Select varieties popular in your local market |
| Maturity Date | Choose varieties suitable for your growing season |
Health of the Root:
Healthy sweet potato roots with no signs of disease or damage are essential for successful slip production. Inspect the roots for:
- Soft spots or bruises
- Cuts or abrasions
- Mold or rot
- Insect damage
Storage Conditions:
Store sweet potato roots in a cool, dark, and well-ventilated area that maintains a temperature of around 55-60°F (13-16°C). Avoid exposing the roots to direct sunlight, excessive heat, or moisture.
Choosing Healthy Sweet Potato Roots
Selecting healthy sweet potato roots, or slips, is crucial for successful propagation. Here are some key factors to consider when choosing roots for planting:
Appearance
Choose roots that are firm, blemish-free, and have a healthy appearance. Avoid roots that are soft, damaged, or have signs of rot or disease.
Size
Roots should be medium to large in size, typically ranging from 4-8 inches in length. Smaller roots may not have sufficient energy reserves for sprouting and plant development.
Age
Freshly harvested roots are generally better for planting than stored roots. Roots that have been stored for extended periods may have lost some of their sprouting vigor.
Variety
Consider the variety of sweet potato you wish to grow. Different varieties have varying maturity dates, skin colors, and flesh characteristics. Research the best varieties for your climate and desired harvest timing.
Disease resistance
If your area is prone to specific pests or diseases, choose varieties that are resistant to those problems. This will help prevent crop losses and ensure a successful harvest.
Table: Characteristics of Healthy Sweet Potato Roots for Planting
| Characteristic | Desired Attributes |
|---|---|
| Appearance | Firm, blemish-free, healthy |
| Size | Medium to large (4-8 inches) |
| Age | Freshly harvested |
| Variety | Suitable for your climate and desired harvest |
| Disease resistance | Resistant to common pests and diseases in your area |
Creating a Warm and Humid Environment
To propagate sweet potato slips successfully, you must provide a warm and humid environment for the cuttings to thrive. Here are three key steps for creating the optimal conditions:
3. Maintaining Adequate Humidity
High humidity levels are crucial for the survival and growth of sweet potato slips. Aim for a relative humidity of around 90-95%. This can be achieved through various methods:
-
Misting
Mist the cuttings regularly with lukewarm water using a spray bottle. Avoid overwatering, as it can lead to root rot.
-
Humidity Tray
Place the cuttings in a seed tray filled with damp pebbles or perlite. The evaporating moisture will create a humid microclimate around the cuttings.
-
Plastic Bag or Cover
Enclose the cuttings in a clear plastic bag or cover a plastic container with a lid to create a humid chamber. Ensure there is adequate air circulation to prevent mold growth.
Bedding the Sweet Potatoes
Bedding is the process of preparing sweet potatoes for sprouting slips. This is a crucial step in the propagation of sweet potatoes, as it allows the potatoes to produce the stems and leaves necessary for planting.
To bed sweet potatoes, follow these steps:
- Select healthy potatoes: Choose firm, disease-free potatoes. Avoid potatoes that have signs of bruising, rot, or damage.
- Cure the potatoes: Before bedding, the potatoes should be cured to promote wound healing. Place them in a warm, well-ventilated area for 5-7 days.
- Prepare the bedding medium: Use a mixture of sand, peat moss, or vermiculite. The medium should be loose and well-draining.
- Plant the potatoes:
- Horizontal Bedding: Place the potatoes horizontally on the bedding medium, about 6 inches apart. Cover them with 2-3 inches of the medium, leaving the tops exposed.
- Vertical Bedding: Insert the potatoes vertically into the medium, with the top third exposed. This method allows for more slips to develop.
- Basket Bedding: This method involves placing potatoes in baskets filled with the bedding medium. Suspend the baskets in a warm, humid environment. Slips will develop along the sides of the potatoes.
| Bedding Method | Advantages | Disadvantages |
|---|---|---|
| Horizontal Bedding | – Easy to manage | – Produces fewer slips |
| Vertical Bedding | – Produces more slips | – Requires more space |
| Basket Bedding | – High yield of slips | – Requires specialized equipment |
Monitoring Sprouting
Check the potato weekly for signs of sprouting. It can take anywhere from 2 to 4 weeks for sprouts to appear. Once you see sprouts, you can move on to trimming the slips.
Trimming
When the sprouts are 4-6 inches long, cut them just above the potato. Cut at a 45-degree angle to prevent rot and with a clean knife to avoid spreading diseases. Remove any damaged or weak sprouts, and leave the healthiest and most vigorous ones.
Once you’ve trimmed the slips, allow them to dry out for a few hours before planting. This will help them develop a protective callus that will make them more resistant to rot.
Steps for Trimming Sweet Potato Slips
| Step | Description |
|---|---|
| 1 | Check the potato weekly for signs of sprouting. |
| 2 | Once the sprouts are 4-6 inches long, cut them just above the potato at a 45-degree angle. |
| 3 | Remove any damaged or weak sprouts. |
| 4 | Let the slips dry out for a few hours before planting. |
Hardening Off the Slips
Hardening off is a crucial step in the process of preparing sweet potato slips for planting. This process gradually exposes the slips to outdoor conditions, allowing them to adapt and toughen up before transplanting. Here are the steps involved:
- Start gradually: Begin by placing the slips in a shaded area outdoors for a few hours each day. Gradually increase the exposure time over the course of a week or two.
- Protect from wind: Ensure the slips are protected from strong winds during the hardening-off process. Winds can easily damage their tender shoots.
- Water regularly: Water the slips regularly to keep them hydrated, but avoid overwatering. Overwatering can lead to root rot.
- Watch for pests: Keep an eye out for pests such as aphids and spider mites during the hardening-off period. Treat any infestations promptly.
- Check for hardening: After 10-14 days of hardening off, the slips should be ready for planting. To check for readiness, gently bend the slips. If they snap easily, they need more time to harden off. If they bend without breaking, they are ready to transplant.
- Transplanting time: When transplanting the slips, handle them carefully to avoid damaging their roots. Space the slips 12-18 inches apart in well-drained soil, and water them deeply after planting.
| Day | Exposure |
|---|---|
| 1-3 | 2-4 hours per day |
| 4-7 | 4-6 hours per day |
| 8-10 | 6-8 hours per day |
| 11-14 | Full sun exposure |
Materials You’ll Need
To get started, you’ll need the following materials:
• Sweet potato slips
• Spade or shovel
• Trowel
• Mulch (optional)
1. Preparing the Slips
Select healthy slips with bright green leaves and sturdy stems. Remove any leaves that are yellowed or damaged.
2. Site Selection
Choose a planting site that receives full sun and has well-drained soil. Avoid areas where water tends to pool.
3. Soil Preparation
Till the soil to a depth of 8-12 inches. Amend the soil with compost or fertilizer to improve its fertility.
4. Planting the Slips
Dig a hole deep enough to accommodate the slip’s roots. Place the slip in the hole and fill it with soil, gently firming it around the stem.
5. Spacing
Space the slips 18-24 inches apart in rows that are 2-3 feet apart. This will give them plenty of room to grow and spread out.
6. Watering
Water the slips deeply after planting. Continue to water regularly, especially during dry periods.
7. Mulching (Optional)
Spread a layer of mulch around the slips to help retain moisture, suppress weeds, and regulate soil temperature. Avoid piling mulch directly against the stems, as this can lead to rot.
| Material | Quantity |
|---|---|
| Sweet potato slips | As many as desired |
| Spade or shovel | 1 |
| Trowel | 1 |
| Mulch (optional) | As needed |
Materials You’ll Need
Before you can start cutting sweet potato slips, you’ll need to gather a few materials:
- Sweet potato tubers
- Sharp knife
- Container for the slips
- Water
Step-by-Step Instructions
Once you have your materials, you can follow these steps to cut sweet potato slips:
- Wash the sweet potato tubers to remove any dirt or debris.
- Cut the tubers into 4- to 6-inch sections, making sure each section has at least one eye (small bump on the surface of the tuber).
- Place the tuber sections in a container of water, making sure the eyes are submerged.
- Keep the container in a warm, well-lit place for 10 to 14 days, or until the slips have grown to be about 6 inches long.
- Once the slips have grown long enough, you can remove them from the water and plant them in the garden.
Spacing and Depth Considerations
Spacing
When planting sweet potato slips, it is important to space them properly to ensure that they have enough room to grow. The recommended spacing is 12 to 18 inches between plants and 3 to 4 feet between rows. You can plant the slips in single rows or in raised beds.
Depth
The depth at which you plant the slips is also important. The roots of the slips should be planted at least 6 inches deep in the soil. If the roots are planted too shallow, they may not be able to get the water and nutrients they need to grow properly.
| Spacing | Depth |
|---|---|
| 12 to 18 inches between plants | At least 6 inches deep |
| 3 to 4 feet between rows |
Watering and Fertilizing
Watering: Sweet potato slips require regular watering, especially during the rooting stage. Keep the soil evenly moist, but avoid overwatering. Allow the top inch of soil to dry out before watering again. Once the slips have rooted, reduce watering to a more moderate level. Deep watering is recommended, especially during hot and dry weather.
Fertilizing: Fertilize sweet potato slips regularly to promote healthy growth and tuber production. Use a balanced, water-soluble fertilizer with a ratio of 2:1:1 (nitrogen, phosphorus, potassium). Apply the fertilizer according to the manufacturer’s instructions, typically every two to three weeks. Avoid over-fertilizing, as this can damage the plants.

How To Cut Sweet Potato Slips For Planting
Sweet potatoes are a warm-season crop that can be grown in many parts of the United States. They are a good source of vitamins A and C, and they are also a good source of dietary fiber. Sweet potatoes can be grown from seed, but they are more commonly grown from slips. Slips are cuttings that are taken from the vines of mature sweet potato plants.
To cut sweet potato slips, you will need a sharp knife and a bucket of water. You will also need to select mature sweet potato plants that are free of disease. To cut the slips, use a sharp knife to cut a 4- to 6-inch section of vine from the main stem of the plant. Make sure that the cutting has at least two nodes, or growing points. Once you have cut the slips, place them in a bucket of water and keep them in a warm, sunny location.
The slips will begin to root in a few days. Once the roots are about 1 inch long, the slips are ready to be planted. To plant the slips, dig a hole that is 6 inches deep and 12 inches wide. Place the slip in the hole and cover it with soil. Water the slip well and keep it moist until it becomes established.
