Maintain proper spacing to allow for good air circulation and prevent overcrowding. Sweet potatoes with sprawling vines can spread up to 12 feet. So you should keep about 3-4 feet between rows.
IV. Caring for Sweet Potatoes in Florida
1. Watering Requirements
Sweet potatoes require consistent watering throughout the growing season. Due to the high temperatures and humidity in Florida, pay close attention to the soil moisture levels of your 15 gallon nursery pots.
You can water deeply once or twice a week, rather than light watering every day. Sweet potatoes are susceptible to root rot in overly wet conditions. Keep the soil good drainage and avoid overwatering.
2. Fertilization Needs
Sweet potatoes require regular fertilization to promote healthy growth and a bountiful harvest. In Florida's sandy soils, use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.
You can apply it every 4-6 weeks during the growing season. This can improve soil fertility and provide essential nutrients for sweet potatoes.
3. Mulching and Weed Control
A layer of organic mulch can help retain moisture, suppress weeds, and regulate soil temperature. For example, straw or shredded leaves. Keep the mulch a few inches away from the base of the plants.
Weeds compete with sweet potatoes for nutrients and can hinder their growth. Regularly pulling or hoeing weeds is recommended. Mulching can also help prevent weed growth.
4. Common Pests and Diseases
Florida has a warm and humid climate. It is ideal for pests and diseases to thrive. For example, south Florida, central Florida and north Florida. So regularly monitor your sweet potatoes for any signs of damage.
Common pests include whiteflies, sweet potato weevils, and root-knot nematodes. You should incorporate organic matter and practice crop rotation. Using insecticidal soap or neem oil can help control pest populations.
Common diseases include Fusarium wilt etc. You can control it by using disease-resistant varieties. Regularly monitor for signs of disease. For example, yellowing or wilting leaves. Promptly remove any infected plants to prevent the spread of disease.

Sweet potatoes thrive in warm weather and require ample sunlight. So make sure your plants receive 6-8 hours of sunlight per day. Your plants in a 20 gallon pot will stunted growth and have small tubers without enough light.
2. Pruning and Vine Management
Sweet potato vines can grow quite long. They may become tangled or overcrowded if left unattended. Regularly prune the vines to promote air circulation and prevent diseases. You can also train the vines to grow in a specific direction by gently tying them to stakes or trellises. This will help maximize space and yield.
Remove any flowering buds that may develop. By removing these buds, your sweet potato plants will put their energy towards producing large, healthy tubers.
3. Dealing with Common Challenges
Weather events: Hurricanes and heavy rains can also be a concern for sweet potato growing in Florida. Provide shelter or cover them with tarps to protect your plants during severe weather.
Stunted growth: If your sweet potato plants are not growing as expected, it could be due to nutrient deficiencies or poor soil quality. Conduct a soil test and amend accordingly to ensure optimal growth.
