Essential Information

  • You can purchase slips from nurseries or online retailers, or you can even start your own slips from a potato you already have.
  • To start your own slips, simply place a sweet potato in a shallow container of water, ensuring that the top of the potato is exposed.
  • Growing Okinawan sweet potatoes is a rewarding experience, allowing you to enjoy the fruits (or should we say, tubers) of your labor.

Okinawan sweet potatoes, also known as “purple yams,” are a vibrant and delicious addition to any garden. Their unique purple flesh and sweet flavor are a delightful treat, but growing them can seem daunting. Fear not! This guide will walk you through the process of planting Okinawan sweet potatoes, from choosing the right slips to harvesting your bountiful crop.

Understanding Okinawan Sweet Potato Slips

Before you can plant, you need to understand the unique planting method of Okinawan sweet potatoes. Unlike other sweet potatoes, Okinawan sweet potatoes are not planted from seed. Instead, they are planted using slips. Slips are essentially small shoots that emerge from the potato itself.

You can purchase slips from nurseries or online retailers, or you can even start your own slips from a potato you already have. To start your own slips, simply place a sweet potato in a shallow container of water, ensuring that the top of the potato is exposed. Within a few weeks, slips will emerge from the potato.

Choosing the Right Location

Okinawan sweet potatoes thrive in warm, sunny locations with well-draining soil. Choose a spot that receives at least six hours of direct sunlight per day. Sandy loam soil is ideal, but these potatoes can also tolerate clay soil, as long as it is well-drained.

Avoid planting in areas with poor drainage, as this can lead to root rot. If your soil is heavy clay, amending it with compost or sand can improve drainage.

Preparing the Soil

Once you’ve chosen your location, it’s time to prepare the soil for planting. Dig a shallow trench, about 4-6 inches deep. The trench should be about 12 inches wide.

Before planting, you can enrich the soil with compost or manure. This will provide nutrients for the growing potatoes and improve soil structure.

Planting Okinawan Sweet Potato Slips

Now it’s time to plant your slips! Here’s how:

1. Spacing: Space your slips 12-18 inches apart in the trench.
2. Planting Depth: Plant the slips with the top 2-3 inches of the slip exposed above the soil line.
3. Watering: Water the slips thoroughly after planting.

Caring for Your Sweet Potatoes

Okinawan sweet potatoes require minimal care once they are planted. Here’s a breakdown of the essential steps:

  • Watering: Water your sweet potatoes regularly, especially during dry periods. The soil should be kept consistently moist but not waterlogged.
  • Weeding: Keep the area around your sweet potato plants weed-free. Weeds compete with the plants for nutrients and water.
  • Fertilizing: You can fertilize your sweet potatoes with a balanced fertilizer a few weeks after planting. However, over-fertilizing can lead to excessive vine growth and reduced tuber production.
  • Hilling: As the plants grow, you can “hill” them by adding soil around the base of the vines. This encourages the formation of more tubers.

Harvesting Your Okinawan Sweet Potatoes

Okinawan sweet potatoes are typically ready for harvest around 100-120 days after planting. However, the exact time will vary depending on your climate and growing conditions.

Here’s how to know when your sweet potatoes are ready for harvest:

  • Vine Color: The leaves of the vine will start to turn yellow and brown.
  • Leaf Drop: The vines will start to die back and shed their leaves.
  • Tuber Size: The tubers will be at least 3-4 inches in diameter.

To harvest your sweet potatoes, carefully dig them up with a garden fork or shovel. Avoid damaging the tubers.

Storing and Enjoying Your Harvest

Once you’ve harvested your Okinawan sweet potatoes, you can store them in a cool, dry place for several months. They are best stored in a single layer, free from any moisture.

Okinawan sweet potatoes can be enjoyed in a variety of ways. They can be boiled, baked, roasted, fried, or used in soups and stews. Their unique flavor and vibrant color make them a delicious and versatile addition to any meal.

A Sweet Farewell: Wrapping Up Your Okinawan Sweet Potato Journey

Growing Okinawan sweet potatoes is a rewarding experience, allowing you to enjoy the fruits (or should we say, tubers) of your labor. Remember, patience and proper care are key to a successful harvest.

From planting slips to harvesting your bounty, this guide has equipped you with the knowledge to cultivate a vibrant and delicious crop of Okinawan sweet potatoes. Now, get out there and start planting!
