When to Harvest Sweet Potatoes: A Guide to Perfect Timing

The ideal time to harvest sweet potatoes varies depending on the variety, climate, and local conditions. However, there are some general guidelines that can help you determine the right window:

Vine Maturity:

Gently dig around the base of the plants to check the size of the tubers. They should be large enough for your desired use.

Skin Color:

The skin of mature sweet potatoes should be smooth and firm, with a deep orange hue.

Days to Maturity:

• Early varieties: 90-120 days
• Mid-season varieties: 120-150 days
• Late varieties: 150-180 days

Note: These are approximate timelines, and actual harvesting times may vary.

Harvesting Techniques: A Step-by-Step Guide

Materials you'll need:

• Garden fork or spade
• Gloves
• Buckets or baskets

1. Choose a sunny day: The soil will be dry and easier to dig.
2. Undercut the tubers: Using a garden fork or spade, carefully insert it into the soil a few inches away from the base of the plant. Gently lift the tubers out.
3. Avoid bruising: Handle the sweet potatoes with care to prevent bruising.
4. Brush off excess soil: Use your hands or a soft brush to remove excess soil from the surface.
5. Cure the sweet potatoes: Place the harvested sweet potatoes in a warm, well-ventilated area for 7-10 days to cure them. This process helps them develop their full flavor and improves their storage life.
