Yams are ready to harvest when they can be easily pulled from the ground, but only after you’ve dug through the dirt and found a tuber. If you can’t find any tubers beneath the surface, then you’re going to have to wait for your yams to grow even larger before harvesting them.

The best way to tell if your yams are ready for harvest is by using a gardening fork or shovel to dig around in the dirt, being careful not to damage any tubers that may be growing below ground level. The yams themselves are typically located within two feet of the surface of the soil, so once you’ve found them (or if you know exactly where they were planted), then you can begin pulling them out of the ground.

Yams are a delicious, nutritious root vegetable that is available year-round. Yams are easy to grow in your own garden, and you can tell when they are ready for harvesting by looking at the plant and the tubers. The leaves of yam plants are dark green and shiny. The top of the plant is flat and looks like a palm tree. The leaves will begin to droop when it is time for harvesting. When you dig up a yam, look for two or three tubers that have no cracks or holes in them. The skin should be smooth and have no blemishes or soft spots.

Yams are best harvested when they are fully mature, which means that the tuber is firm and not too hard, yet not soft and mushy. Yams should be harvested when the skin has changed from green to a yellowish-brown color. To tell if a yam is ripe for harvesting, squeeze it gently between your fingers. If it gives slightly but does not feel squishy or soft, then it is ready for harvest.

The edible yam family, Dioscoreaceae, is a large and diverse group. There are over 600 species in the family and about 150 genera. Most of these are native to Africa but some are found in Asia, Australia and even North America. Some species have both tubers and vines while others have one or the other. Most of these plants produce edible fruits that can be used as food items or medicine. However, there are also some poisonous varieties which cause serious illness if eaten raw (i.e., uncooked). These include: 1) common henbane (Hyoscyamus niger), 2) black nightshade (Solanum nigrum), 3) wolfsbane plant (Aconitum lycoctonum), 4) European mandrake root (Mandragora officinarum).

4 Things To Know About Yams

You may be wondering how to tell when a yam is ready to harvest.

First, know that yams and sweet potatoes are not the same thing. The two plants look very similar and grow in similar climates, but they’re actually different species of plants.

Sweet potatoes are more starchy than yams and have a higher sugar content than what you’ll find in a typical yam. Sweet potatoes also tend to take longer to ripen before harvesting them—upwards of three months or more for most varieties. On the other hand, there’s no need for such patience with your garden-grown yams. They can reach maturity within two months of planting depending on the variety you choose (and how quickly it grows).

How to Determine That Yams Are Ready to Harvest

How to Determine That Yams Are Ready to Harvest

If you want to harvest yams, you will need to wait until the vines stop growing. The best way to tell when this happens is by observing your plants. If they are still actively growing and putting out new leaves, it is not yet time for harvest. When this occurs, the plant will become dormant and allow its roots to develop fully before sending up any more shoots or leaves (like a dandelion).

When plants are actively growing, their stems are green in color; however, once they begin their period of dormancy and go into winter mode (which usually occurs sometime around November), their stems will turn brownish-yellow in color as they prepare themselves for winter’s first frost. Once this occurs on all parts of the plant (stems included), then it’s safe to say that harvesting time has arrived.

How To Tell When Sweet Potato Vines Stop Growing

You may have heard that yams are vines and sweet potatoes are vines, but this is not true. Yams grow in the ground, while sweet potatoes grow on vines. They’re also different types of plants: yams are tubers, while sweet potatoes are an annual vine plant.

So if you’re growing your own yam or sweet potato patch, it’s important to know when to harvest each type of tuber so you don’t miss the window for optimal eating quality.

The Edible Yam or Sweet Potato?

It’s easy to get confused by the terms “yam” and “sweet potato.” They’re often used interchangeably, but there is a difference: yams are actually a type of sweet potato. For example, the popular Yam Dessert recipe calls for “sweet potatoes.” This can be a little confusing because it seems like you might have to go out of your way to find a yam for this recipe instead of just using a regular sweet potato. The truth is that the two types of vegetables have very similar nutritional profiles—they both contain high amounts of vitamin C, potassium, calcium and B6. That said, it may be worth looking into yams if you want an extra boost in vitamins A (beta-carotene) and E as well as iron and magnesium.

Because they’re more nutritious than their orange counterparts (and they taste great too), we recommend finding them at your local farmers market or grocery store first before venturing out into uncharted territory with these unfamiliar tubers

These are some key things to know about yams.

This is good to know:

  • Yams are related to sweet potatoes, but they’re actually starchy and sweet. They grow well in warm climates and can be harvested at different stages of maturity. Yams are a good source of vitamin C and fiber, so they’re great for people with diabetes or high cholesterol.
  • In fact, yams are so nutritious that they may very well be the perfect food for you.
