Introduction to Growing Amaranth: History and Benefits

Exploring the fascinating past and numerous benefits of amaranth reveals why it’s a must-have in your garden. This remarkable plant has a rich history, deeply rooted in the cultures of ancient civilizations. Once a staple for the Aztecs, it was not only used in rituals but also crafted into delicious treats mixed with honey.

However, the Spanish Conquistadores banned its cultivation, pushing it underground for centuries. Today, amaranth has made a stunning comeback as a superfood, and I find growing it feels like participating in a revival of this ancient crop.

A Brief History of Amaranth

Amaranth’s journey through history is captivating. It survived the ban imposed by the Spanish, and its wild counterpart, known as redroot pigweed, still flourishes as a common weed. I remember my first encounter with wild amaranth, and how it opened my eyes to its edible potential.

Why Grow Amaranth? Nutritional and Ornamental Value

Growing amaranth offers incredible nutritional benefits. The seeds contain about 14 to 16% protein, making them a complete protein source, high in lysine. They are also packed with essential minerals like calcium, iron, and magnesium. This makes amaranth a nutrient-dense food choice.

In addition to its nutritional punch, amaranth is visually stunning. Its velvety flowers cascade in shades of magenta and golden bronze, adding a dramatic flair to any garden. I find that these vibrant colors enhance the beauty of my outdoor space.

Types of Amaranth Uses: Grain, Greens, and Flowers

There are three main uses for amaranth: grain production, leafy greens, and ornamental flowers. The grain varieties typically have white or yellowish seeds, milder than the wild types. The young leaves of amaranth are excellent cooking greens, often mixed with kale or mustard greens in my winter soups.

Amaranth also serves as a pseudo-grain, similar to quinoa, making it a versatile gluten-free option for various dishes. I appreciate how species amaranth, like A. cruentus and A. hypochondriacus, each bring unique traits to the table.

Selecting the Right Amaranth Seeds and Varieties

Picking the best amaranth seeds and varieties is key to achieving your gardening goals. With around 75 species of Amaranthus, the options can be overwhelming. However, understanding the differences between grain varieties, leafy greens, and ornamental types will help you make informed choices.

Grain Varieties vs. Leafy Greens vs. Ornamental Types

Grain amaranth seeds are typically white or yellowish, offering a mild flavor. In contrast, leafy greens often have shiny black seed coats packed with anthocyanin, giving them a stronger taste. Ornamental types are equally exciting, with two main forms: the Spike type featuring upright plumes and the Trailing type showcasing draping ropes.

Choosing Seeds for Your Growing Goals

When selecting seeds, consider your specific goals. If you’re interested in cut flowers, choose varieties like A. caudatus ‘Coral Fountain’ for its cascading coral blooms or ‘Love-lies-bleeding’ for its dramatic wine-red ropes. For grain production, I recommend A. hypochondriacus ‘Golden Giant’, which can yield up to one pound of seeds per plant.

Popular Amaranth Varieties for United States Gardens

In the United States, several amaranth varieties stand out. ‘Plainsman’ is favored by commercial growers for its uniform maturity. For home gardeners, ‘Opopeo’ from Michoacan, Mexico, is a tall variety that produces well. Additionally, the leafy variety A. tricolor ‘Chinese multicolor’ offers stunning leaf patterns, making it perfect for salads.

Ultimately, selecting the right amaranth varieties upfront makes all the difference in your harvest success. Whether you’re after nutritious grains, vibrant flowers, or delicious greens, the right seeds will set you on the path to a thriving garden.

Preparing Your Garden and Planting Amaranth

Getting your garden ready for amaranth is an essential step for a successful harvest. These plants thrive in heat and require full sun, so finding a spot that receives at least six hours of direct light is crucial. Amaranth is not frost tolerant, so it’s important to wait until the last frost has passed and the soil has warmed up.

Soil Requirements and Site Selection

Amaranth prefers loose, fertile, and well-draining soil. However, it is quite forgiving and can tolerate less-than-perfect conditions. The pH level isn’t a major concern, making it easier for gardeners to find suitable spots in their yards.

When and How to Plant: Direct Sowing vs. Transplants

Timing is key when planting amaranth. I recommend waiting until after the last frost when the soil temperature is ideal. You can choose between direct sowing or starting seeds indoors. For direct sowing, prepare the bed and sow the seeds sparingly, barely covering them with a light brushing of soil. Once true leaves appear, thin them to one plant every 12 inches.

If you prefer starting seeds indoors, do so about six to eight weeks before the last frost. Use soil blocks or trays, planting the seeds about 1/8 inch deep. It’s best to place two seeds per cell and thin to one once they sprout. Keep the soil lightly moist and provide plenty of light for healthy growth.

Seed Starting Tips and Spacing Guidelines

Using #72 cell trays has worked well for me. I typically sow my seeds in late April and thin them to single plants. When it comes to spacing, I recommend 12 to 15 inches between plants and keeping rows about three feet apart. This spacing is important because amaranth plants can grow quite large.

Protecting Seedlings and Early Growth

Amaranth seedlings are slow-growing at first and can be vulnerable to drought stress. They also resemble redroot pigweed, making transplanting a good option to avoid confusion. I harden off my seedlings before transplanting them outdoors in mid-May, just like I do with tomatoes and peppers.

Additionally, young amaranth plants are a favorite snack for deer. To protect them, I suggest stretching string barriers about four feet high around the patch. This method works surprisingly well for small areas. Once established, these plants become remarkably drought-tolerant and need only occasional watering.

Caring for Amaranth Plants: Tips for Healthy Growth

Caring for amaranth plants is essential for ensuring they thrive in your garden. With the right attention, these resilient plants can produce beautiful blooms and nutritious greens. Here are some key aspects to consider for healthy growth.

Watering, Fertilizing, and Soil Maintenance

Amaranth plants require consistent moisture, especially during their early growth stages. I recommend providing about 1 to 1.5 inches of water each week. This keeps the soil moist but not soggy. Watering in the morning is ideal, as it allows plants to absorb moisture before the heat of the day.

While amaranth isn’t a heavy feeder, enriching the soil with compost before planting helps promote healthier growth. Aim for fertile, well-draining soil with a pH between 6.0 and 7.0. Adding organic matter improves soil structure and fertility.

Mulching around young plants can be a game-changer. A 3-inch layer of mulch helps retain moisture, keeps the soil cool, and suppresses weeds. This is particularly beneficial when amaranth plants are still young and vulnerable.

Supporting Taller Varieties and Managing Plant Size

Some amaranth varieties can grow quite large, reaching over 6 feet tall. To prevent them from toppling over, consider using tomato cages or netting for support. This ensures they remain upright and healthy, especially when they begin to flower.

Additionally, I use a technique called pinching. When the plants are about knee-high, I cut back the center stem. This encourages multiple branches, resulting in more manageable blooms for arrangements. If you forget to pinch, you may end up with massive plants that have stems too thick for vases.

Common Pests and How to Prevent Damage

Like any crop, amaranth can attract pests. I’ve found that using floating row covers can deter many common pests. Regularly inspecting the undersides of leaves is crucial. If you spot any pests, handpicking them or applying an organic BT spray can be effective.

Another tip is to keep the garden area clean of old plant debris. This reduces hiding spots for pests and helps maintain a healthy environment for your amaranth plants.

Pinching and Deadheading for Better Bloom and Yield

Deadheading spent blooms encourages amaranth plants to continue producing flowers until frost. This extends the harvest window and provides more beautiful blooms for arrangements. Plus, young leaves can be harvested throughout the season for cooking greens. I love freezing them for midwinter soups, especially with kale.

After the first few weeks of slow growth, amaranth plants grow explosively. They quickly close the canopy, shading out weeds naturally. This makes maintenance easier and allows the plants to thrive.

Care Aspect	Recommendation
Watering	1 to 1.5 inches per week
Soil Type	Fertile, well-draining, pH 6.0-7.0
Mulching	3-inch layer around young plants
Support	Tomato cages or netting for tall varieties
Pest Control	Floating row covers and regular inspections

Companion Planting and Intercropping with Amaranth

Companion planting can enhance the productivity of your garden, especially when it comes to amaranth. I love the idea of growing different plants together to create a more vibrant and fruitful space. One of my favorite strategies is pairing dry pole beans with my amaranth plants. This combination maximizes every square foot of my garden.

Benefits of Growing Pole Beans and Other Companions

Using pole beans like ‘Orlando’s’ and ‘Roark’ alongside amaranth offers numerous advantages. These beans naturally climb the sturdy amaranth stalks, providing a bonus harvest without requiring additional space. I typically sow the beans around Memorial Day when the amaranth is already a few inches tall. This timing allows the beans to thrive without overwhelming the young plants.

Managing Plant Spacing and Growth Interactions

When intercropping, managing plant spacing is crucial. I space my amaranth rows about 3 feet apart and place the plants 1.5 to 2 feet apart. This arrangement accommodates both crops while allowing them to flourish. Although beans yield about 75% of what they would on bare poles due to shade, amaranth remains unaffected, making it a win-win situation.

Incorporating Green Manure and Living Mulches

Another aspect of my gardening strategy involves using ladino clover as a living mulch. I sow it in early July after my final cultivation. This clover fixes nitrogen for the following year, enriching the soil without competing with the current crop. While it doesn’t help the existing amaranth plants, it doesn’t compete for soil nitrogen either, making it a neutral addition.

The clover grows slowly in the shade of the amaranth all summer. After frost kills the foliage, it explodes with growth, providing two half-seasons of soil building. This intercropping approach transforms one garden bed into a multi-functional powerhouse, producing grain, beans, and enhancing soil fertility all at once.

Harvesting Amaranth for Grain and Flowers

As autumn approaches, it’s time to focus on the crucial task of harvesting amaranth. This process is essential for ensuring that you enjoy the full benefits of this versatile crop. Understanding when and how to harvest can significantly impact the quality of your grains and flowers.

Knowing When to Harvest Grain and Flower Heads

Timing is everything when it comes to harvesting. For grain, I check the flower heads by gently brushing them with my hand. If seeds fall into my palm, it’s time to act fast. Typically, I aim for early October but often wait a couple of weeks longer. This allows later-formed seed heads to fully ripen and cure on the stalk.

When it comes to flowers, I harvest them when about ¾ of the tiny blooms are open and vibrant. If I wait too long, the mature heads will drop seeds everywhere, creating a mess.

Harvest Techniques: Cutting, Drying, and Storage

For grain, I cut the plants about 3 feet high. This height helps speed up the drying process. I then hang them from beams in my shed for several weeks to ensure they dry perfectly before threshing.

When harvesting flowers, I snip the heads carefully, ensuring they are still colorful and fresh. After cutting, I place them in a bucket in a warm, dry area, out of direct sunlight, for about two weeks to dry properly.

Threshing, Winnowing, and Processing Seeds

Threshing amaranth is quite fun! I lay the dry plants on a tarp and perform a little “chicken-dance” to release the tiny seeds. It’s surprisingly satisfying! After that, I winnow the seeds by pouring them back and forth between two bowls in a light breeze. This removes chaff and any stowaway insects.

Amaranth seeds are hull-less, making them easy to process. I use my Corona hand-mill to grind them into flour, passing them through three or four times for a fine meal.

Using Amaranth Seeds and Flour in the Kitchen

In the kitchen, I love using whole amaranth seeds in various dishes. They can be roasted, added to veggie-burgers, or even popped like popcorn. Cooking them like quinoa yields a protein-packed grain that complements many meals.

For baking, I often incorporate amaranth flour into my recipes. It adds a unique richness to vegan waffles and muffins, but I always remember to use it sparingly. Too much can make the baked goods heavy.

Finally, I ensure that my dried amaranth flowers have a vase life of 7 to 10 days with proper care. I remove most leaves to help the stems rehydrate quickly, making them perfect for arrangements.

Harvest Aspect	Recommendation
Grain Harvest Timing	Check seeds in early October; wait for full ripening
Flower Harvest Timing	Snip when ¾ blooms are open
Cutting Height for Grain	3 feet high
Drying Method for Flowers	Hang upside down in a warm, dry place
Winnowing Technique	Pour seeds between bowls in a light breeze
