Begin by gently washing the tuber with a soft brush under running water to remove any dirt or debris. This will help you spot any visible issues.
Look for eyes that are discolored, sunken, or have an unusual texture. Avoid tubers with soft spots, mold, or a sour smell – these can be signs of rot or fungal infection. Check the skin for cracks or bruises, which can provide entry points for pathogens.
If you notice any defects during inspection, it’s crucial to cull those tubers immediately. Set aside any healthy-looking eyes and store them in a cool, dark place until ready for use. This will help prevent cross-contamination of disease-causing organisms and ensure your slips have the best chance at success.
Starting Sweet Potato Slips from Eyes
When it comes to starting sweet potato slips from eyes, you’ll want to follow a specific process to encourage healthy growth and prevent rot. This involves carefully preparing your seed eyes for planting.
Collecting and Cleaning Eyes
Collecting mature sweet potatoes with healthy eyes is crucial for successful slip production. To do this, select tubers that are at least 3-4 months old and have plenty of nodes, which are the small buds on the stem end. These nodes will eventually develop into slips.
When choosing a sweet potato for eye collection, look for ones that are free from bruises, cuts, or any other damage. Gently wash the tubers in warm water to remove any dirt or debris, and then dry them with a clean towel. This helps prevent bacterial growth during the eye collection process.
To collect the eyes, carefully cut the sweet potato into 1-inch pieces, making sure each piece has at least one node. Then, soak the pieces in a container of water for about an hour to allow the nodes to swell and become more visible. Once the nodes are swollen, use a sharp object like a toothpick or small knife to carefully pry them off from the tuber. Make sure to handle the eyes gently to avoid damaging them. Now your sweet potatoes are ready for the next step in starting slips – cleaning and preparing them for rooting.
Planting Eyes in Water or Soil
When planting sweet potato eyes in water or soil, it’s essential to follow some simple steps to ensure successful germination. To start with water, select a clear glass or cup and fill it with enough water to cover the eye by about an inch. Place one or two eyes in the water, making sure they’re fully submerged but not touching the bottom of the container. Keep the water level topped up as it evaporates.
The ideal temperature for sweet potato germination is between 65°F to 75°F (18°C to 24°C). A warm location with indirect sunlight is perfect. Change the water every few days to prevent bacterial growth and promote healthy roots development.
When planting in soil, use a seed starting mix or a well-draining potting mix. Plant the eye about an inch deep and firm the soil gently around it. Water thoroughly and maintain a consistent moisture level until sprouts appear. Be patient as germination can take anywhere from 1-3 weeks depending on conditions.
Starting Sweet Potato Slips from Tubers
To successfully start sweet potato slips from tubers, you’ll need to create a warm and humid environment that mimics ideal conditions for germination. This section will walk you through the process step by step.
Preparing and Chitting Tubers
Preparing sweet potato tubers for slipping is an essential step to ensure successful growth of healthy slips. To begin, select healthy, disease-free tubers with plenty of “eyes” – the small buds that will eventually develop into stems. Avoid using deformed or rotting tubers, as these can transfer diseases to your new plants.
Before chitting, wash the selected tubers gently in warm water to remove any dirt or debris. Dry them thoroughly with a clean towel and place them in a light, cool location – around 60-70°F (15-21°C) is ideal. This will help stimulate growth from the eyes. Keep the tubers away from direct sunlight, which can cause them to sprout unevenly.
Chitting typically takes 2-4 weeks, depending on the variety and growing conditions. Once you notice green shoots emerging from the eyes, it’s time to proceed with taking slips. This usually occurs when the shoots are around 1-2 inches (2.5-5 cm) long. Gently twist or cut the new growth at a node – where a leaf meets the stem – to create a slip that can be used for propagation.
Planting Tubers in Water or Soil
When planting sweet potato tubers, you have two options: water or soil. Both methods can be effective, but the key to successful germination lies in providing the right conditions for the tuber eyes to sprout.
To plant a tuber in water, start by filling a jar or container with lukewarm water. Make sure the water is not too cold, as this can slow down germination. Next, slice the tuber into 1-2 inch pieces, making sure each piece has at least one eye. Place the tuber slices in the water, and within 7-10 days, you should start to see sprouts emerging from the eyes.
Alternatively, you can plant a tuber directly in soil. Choose a pot or container with good drainage, and fill it with a well-draining potting mix. Plant the tuber slice about an inch deep, making sure the eye is facing upwards. Keep the soil consistently moist but not waterlogged. In both cases, provide bright, indirect light and maintain a temperature between 65-75°F (18-24°C) for optimal germination.
Keep in mind that planting in water can be a more convenient option, as it allows you to see the sprouts emerging from the tuber eyes. However, some growers find that planting directly in soil yields stronger, healthier slips.
Optimizing Conditions for Sweet Potato Slip Growth
To maximize sweet potato slip growth, it’s crucial to understand how temperature, light, and humidity impact development, so let’s dive into ideal conditions.
Providing Adequate Light and Temperature
Providing adequate light and temperature conditions is crucial for sweet potato slip growth. As you nurture your slips, ensure they receive sufficient light to promote healthy development. Sweet potatoes require a warm environment with temperatures between 65°F to 75°F (18°C to 24°C) for optimal growth.
When placing your slips in a bright location, consider using grow lights if natural sunlight isn’t available. Aim for at least 12-14 hours of supplemental lighting per day to encourage robust development. Avoid direct sunlight, as it can cause scorching or discoloration on the leaves.
Maintain a consistent temperature range to prevent stress and promote steady growth. Keep your slips away from drafts, air conditioning vents, and cold windowsills, which can cause sudden drops in temperature. Monitor your slips’ response to their environment and adjust lighting or temperature as needed to ensure they thrive.
In addition, avoid placing your slips near extreme temperatures, such as radiators or heating vents, as this can also cause stress. By providing the right balance of light and temperature, you’ll be well on your way to growing healthy, robust sweet potato slips.

Maintaining proper water quality and circulation is crucial for healthy slip growth. Water that’s too alkaline or acidic can inhibit root development, while stagnant water can lead to the growth of algae and fungi that harm your slips. To avoid these issues, use a water testing kit to monitor pH levels daily. Keep the water slightly acidic, between 5.0 and 6.5, by adding peat moss or sulfuric acid.
Change the water every 2-3 days to prevent nutrient depletion and reduce the risk of contamination. Add a balanced fertilizer specifically formulated for hydroponics once a week to provide essential nutrients for growth. Keep the water circulating with an aerator pump or air stones to maintain oxygen levels, promoting healthy root development.
For optimal results, use a container with good drainage holes to prevent waterlogged conditions. Regularly inspect your slips for signs of stress or disease, adjusting water quality and circulation as needed to ensure their continued health and growth. By maintaining proper water quality and circulation, you’ll be well on your way to growing healthy, robust sweet potato slips from your tubers.
Transplanting Sweet Potato Slips into Larger Containers or Outdoor Gardens
Once you have your sweet potato slips, it’s time to give them more space to grow. Next, we’ll cover how to transplant them into larger containers or directly into your garden.
Preparing Containers and Gardens
Before transplanting sweet potato slips into larger containers or outdoor gardens, it’s essential to prepare the soil and containers properly. This will ensure that the slips have a healthy start and thrive throughout their growth.
To begin with, select containers that are at least 5-7 gallons in size to accommodate the mature sweet potato plant. Make sure they have drainage holes to prevent waterlogged soil. You can use plastic or clay pots, but avoid metal ones as they can cause the roots to grow in a circular pattern.
If you’re transplanting into outdoor gardens, prepare the soil by loosening it to a depth of about 12 inches. Mix in a 2-inch layer of compost or well-rotted manure to provide nutrients and improve drainage. Create raised beds if your garden has poor soil or is prone to waterlogging.
In both containers and gardens, ensure that the temperature remains between 65°F to 75°F (18°C to 24°C), which is ideal for sweet potato slips. Avoid transplanting during extreme weather conditions like heavy rainfall or intense heatwaves. Water the soil gently but thoroughly after transplanting to settle the roots.
Handling and Transplanting Slips
When handling sweet potato slips, it’s essential to be gentle to avoid damaging the delicate stems and roots. To do this, carefully lift each slip out of its container by the leaves, making sure not to touch the stem or roots with your fingers. You can also use a pair of tweezers to gently grasp the stem just above the node where the leaf meets the stem.
When transplanting slips into larger containers or outdoor gardens, wait until they have at least two sets of true leaves. This ensures they are strong enough to withstand the shock of being transplanted and will give them a better chance of establishing themselves quickly. Before transplanting, prepare your containers by filling them with well-draining potting mix and gently firming it down.
To plant, dig a hole slightly larger than the slip’s root system, then place the slip in the hole, making sure the soil level is the same as it was in the original container. Water thoroughly to settle the soil around the roots. After transplanting, keep the soil consistently moist but not waterlogged, and provide bright indirect light until established.
Monitor your slips closely for any signs of stress or disease after transplanting, such as yellowing leaves or softening stems. If you notice any issues, take action promptly by pruning affected areas or adjusting your care routine.
