Purple yams are perennial plants that are grown in tropical climates. They grow best in hot, humid environments and require a lot of water. Purple yams can be harvested several months after planting, but they will not produce their best yields until they have been growing for at least a year.

Purple yam is an annual vine that is grown in the tropics. It can be grown in U.S. Department of Agriculture plant hardiness zones 10 through 12 and requires a long growing season of at least 100 frost-free days. The seed germinates in 3 to 4 weeks and produces tubers in about six months. The vines should be harvested when they begin to die back naturally, which can take up to 8 months after planting.

Purple yams are harvested about 3 months after planting. The purple yam is a perennial plant, so it will continue to grow throughout the year. The plant can be harvested from January through December, but the best time to harvest them is between April and June.

The tubers of purple yam (Dioscorea alata) are a staple in many tropical and subtropical regions of the world. They are one of the most important root crops in Asia, where they are used to make desserts and sometimes even wine. Purple yams can be harvested within six months of planting, or sooner if you take steps to harvest a baby crop earlier on for immediate consumption.

Growing purple yam is easy.

Purple yam is a tropical plant that you can grow in areas with warm summers, like southern Florida and the Gulf Coast. It’s a perennial, vine-like vegetable with purple tubers on the vine. Purple yam is also known as ube or taro root.

Purple yams are easy to grow from seed. When growing purple yam plants, it’s best to start them indoors about 8 weeks before your last frost date. That way, your plants will be ready for transplanting outdoors at the right time of year (about 6 weeks after planting). In other words: If there’s no danger of frost in your area yet but your local nursery still has seeds available in late summer or early fall… go ahead and buy them now.

How to grow purple yam

Plant the Purple Yam in the spring, once all danger of frost has passed.

  • Plant in full sun and well-drained soil.
  • A raised bed works very well for these roots because they are large, heavy, and need good drainage. They will grow best if you also add plenty of compost or other organic material to your soil before planting purple yams.
  • If you live in a climate where winter temperatures occasionally dip below freezing, it is important that you protect your crop from freezing by covering it with mulch or burlap after the first hard frost—just make sure not to let any water build up around the base.

Whether you choose to plant them directly into the ground or start them indoors first (which is recommended if any frosts are expected), purple yams require plenty of room to grow—and when finished harvesting, these plants can reach heights over 10 feet tall. You’ll want at least 6 feet between each one so they have enough space throughout their life cycle. To prevent crowding later on down the road when they reach maturity (which takes roughly three years), stagger your rows accordingly; this means alternating rows every few months instead of planting them all at once like normal crops do back home

When to plant purple yams

Planting purple yams is best done in the spring or fall. In order to plant your purple yam, you need to make sure that the soil temperature is above 50 degrees Fahrenheit and then wait for it to go above 60 degrees Fahrenheit at night. If you live in an area where the winter temperatures are below freezing and you want to grow a purple yam from seedlings, then you will need to start them indoors early enough so that they can be planted outside once the soil temperature reaches 70 degrees Fahrenheit.

Prepare the soil with compost or well-rotted manure

To prepare the soil for planting, you will need to amend it with compost or manure. For best results, add compost or manure to the soil at least 2 weeks before planting.

Plant purple yam

Planting purple yam is as easy as following a few simple steps. First, be sure to select an area with full sun and well-drained soil. Purple yams prefer loose or sandy loam, but they can also thrive in clay soils if amended with sand or compost.

It’s best to plant the tubers in spring when the soil temperatures have reached at least 50 degrees Fahrenheit (10 C). Planting purple yam in raised beds will help keep their roots from sitting in waterlogged conditions for long periods of time.

Alternatively, you can plant purple yam in late summer through fall or winter by digging large holes six inches deep and spaced eight inches apart for each tuber. Keep them watered regularly until harvest time begins about nine months later.

Care of purple yam plants

Purple yams are a versatile vegetable that can be stored for long periods of time. Purple yams are not hard to grow and require little maintenance, but they do need to be watered regularly and fertilized regularly. There are many pests that will eat purple yams, so it is important to know how to control those bugs. The following article will help you care for your purple yam plants:

  • Watering: If you do not water your plant often enough, it may die from lack of water or get brown spots on its leaves because there is too much sunlight. You should water your plant once every few weeks in the summertime and when rain does not come often enough in other seasons depending on where you live in North America…
  • Fertilizing: You should use fertilizer at least once every two months during growing season; this will ensure strong root growth as well as healthy foliage.. Your soil needs either organic compost or some kind of fertilizer such as Miracle-Gro (which contains organic material) added before planting seeds.. Be sure not to overdo it though because too much nitrogen can cause mildew problems later down the line.”

Fertilizing purple yams

Once your purple yams are established and have reached a height of at least 12 inches, they can be fertilized. Fertilize purple yams once every two to three weeks from early spring until the first frost.

To ensure healthy growth, use a balanced fertilizer with high nitrogen content (less than 1 percent), such as 16-16-8. Avoid using fertilizers that contain higher amounts of potassium or phosphorus because these will stunt the plant’s root development and may cause it to die prematurely. Do not use any kind of fertilizer with more magnesium in it than calcium—this combination will also kill off your purple yams before they’ve had a chance to grow properly.

If you want to skip this step entirely and just leave nature take its course, then all you have left is waiting until harvest time comes around again (see below).

Purple sweet potato production

  • Plant purple sweet potato in the spring.
  • Plant purple sweet potato in late summer.
  • Plant purple sweet potato in the fall.
  • Plant purple sweet potato in the winter.

This tuber can deliver multiple harvests per year when growing in hot tropical climates.

Growing purple yams is easy. You can harvest fresh yams as soon as they are large enough to eat, and the tuber will continue to produce more tubers throughout the growing season. When growing in hot tropical climates, purple yams can deliver multiple harvests per year if you’re able to cultivate a healthy root system.

Planting time: Planting time is when you put your seeds or seedlings into the ground. This occurs before any frost or freezing temperatures occur if outdoor planting is done outdoors (in an area where there are no frost-related issues). You may also be able to plant some varieties indoors before the last frost passes, depending on how cold it gets at night where you live (you’ll want your plants outside ASAP once it’s warm enough). If you live somewhere like southern Florida, where winter never happens and everything stays warm all year long (or even into spring), you’ll probably plant your Purple Yam in late fall before any heavy rains start falling so that it doesn’t rot from too much waterlogging during rainy seasons.

Final words,

Purple yam is one of the most popular tubers grown in tropical countries because of its high nutritional value. It takes about 8 to 10 months for the purple yam to be harvested after planting. However, you can harvest 3 harvests in a year if you plant different varieties at one time or use cuttings from plants that have been harvested recently (within 3 months).
