Growing sweet potatoes can be a rewarding experience, especially in the beautiful state of Utah. With its varying climate and rich soil, Utah provides an excellent environment for producing these delicious tubers. In this article, we will explore everything you need to know about growing sweet potatoes in Utah, from selecting the right variety to planting, caring for, and harvesting your crop.
Sweet potatoes (Ipomoea batatas) are warm-season crops that thrive in well-drained soil with plenty of sunlight. Unlike regular potatoes, which grow underground as tubers, sweet potatoes develop their edible roots underground while the plant itself grows vines on the surface. Known for their sweet flavor and vibrant orange flesh, sweet potatoes are not only delicious but also packed with nutrients like vitamins A and C, fiber, and antioxidants.
When it comes to growing sweet potatoes in Utah, selecting the right variety is crucial. There are many types of sweet potatoes, each with its unique flavor profile and growth requirements. Some popular varieties include:
For Utah’s climate, look for varieties that mature relatively quickly (around 90-120 days) to ensure they can be harvested before the first frost.
Sweet potatoes prefer loose, well-draining soil rich in organic matter. Here’s how you can prepare your garden bed:
Choose a Location: Find a sunny spot in your garden that receives at least 6-8 hours of direct sunlight daily.
Test Your Soil: Before planting, perform a soil test to determine its pH level and nutrient content. Sweet potatoes thrive best in slightly acidic to neutral pH (around 5.8 to 6.5).
Amend the Soil: Based on your soil test results, you may need to amend your soil with compost or well-rotted manure to improve fertility and drainage. Avoid using fresh manure as it can lead to root rot.
Prepare the Bed: Loosen the soil to a depth of at least 12 inches using a garden fork or tiller. This helps promote good root development.
The ideal time to plant sweet potato slips (the young plants sprouted from tubers) in Utah is after the last frost date, typically around mid-May to early June. Follow these steps for successful planting:
Obtain Slips: You can purchase slips from local garden centers or grow them yourself by placing whole sweet potatoes in water until they sprout.
Spacing: Space slips about 12-18 inches apart in rows that are approximately 3 feet apart. This provides ample room for the vines to spread out.
Planting Depth: Plant slips deep enough so that only the top leaves are above ground, ensuring good anchorage as they grow.
Watering: Water deeply after planting to help establish the slips but avoid waterlogging the soil.
Proper care during the growing season is essential for healthy plants and a bountiful harvest.
Sweet potatoes need consistent moisture, especially during dry spells. However, it’s important not to overwater as this can lead to rot. Aim for about an inch of water per week through rainfall or irrigation.
Weeds compete with sweet potatoes for nutrients and water. Regularly check your garden bed and remove weeds by hand or use mulch around your plants to suppress weed growth while retaining moisture.
About four weeks after planting, consider applying a balanced fertilizer with low nitrogen levels (like 5-10-10). Excess nitrogen can result in lush vines but poor tuber development.
Common pests include aphids, vine borers, and cutworms. Regularly inspect your plants and apply organic pest control methods when necessary, such as neem oil or insecticidal soap.
As sweet potato plants grow, they will produce long vines that spread across the ground. You may choose to train them on trellises or allow them to sprawl naturally; however, free-spreading vines often produce larger tubers since they have more room to develop beneath the surface.
Sweet potatoes are typically ready for harvest about 90-120 days after planting but can be harvested earlier if needed. Signs that your sweet potatoes are ready include yellowing leaves and dying vines.
Prepare Your Tools: Use a spading fork or shovel for digging carefully around the base of each plant.
Digging: Gently loosen the soil about 12 inches away from each plant’s base before lifting them out carefully to avoid bruising.
Handling: Handle harvested sweet potatoes with care since they are prone to bruising and damage.
After harvesting, curing is essential for enhancing flavor and extending storage life:
