How to Grow Amaranth in Pennsylvania

Amaranth, a versatile and nutritious plant, has been cultivated for thousands of years. With its vibrant colors and numerous health benefits, it’s no wonder that many gardeners are eager to grow amaranth in their backyards. If you live in Pennsylvania and are interested in adding amaranth to your garden, this guide will provide you with everything you need to know, from selecting the right variety to harvesting your crop.

Understanding Amaranth

What is Amaranth?

Amaranth is a group of plants in the Amaranthaceae family that includes around 60 species. This ancient grain is known for its edible seeds, leaves, and vibrant flowers. The seeds are gluten-free and high in protein, fiber, and essential amino acids, making them an excellent food source. Additionally, the leaves can be eaten like spinach and are rich in vitamins A and C.

Benefits of Growing Amaranth

  1. Nutritional Value: Amaranth seeds are a complete protein source, containing all nine essential amino acids.
  2. Versatility: Both seeds and leaves can be used in various culinary dishes.
  3. Drought Resistance: Amaranth is well-suited for areas with sporadic rainfall, making it a resilient choice for gardeners.
  4. Pest Resistance: Generally, amaranth is not a target for many pests, reducing the need for pesticides.

Choosing the Right Variety

When planning to grow amaranth in Pennsylvania, it’s essential to choose the right variety suited to your climate and purpose.

Common Varieties

  1. Amaranthus cruentus: Known as red amaranth or African spinach, this variety is commonly grown for its seeds.
  2. Amaranthus caudatus: Also known as love-lies-bleeding, this ornamental variety is grown for its striking flower clusters.
  3. Amaranthus hypochondriacus: This species is often referred to as prince-of-wales feather; it produces small seeds rich in nutrients.

Consider what you want from your amaranth crop—whether for ornamental purposes or for consuming leaves and seeds—before choosing a variety.

Preparing Your Garden

Soil Requirements

Amaranth thrives in well-drained, loamy soil with a pH level between 6.0 and 7.0. Before planting:

  1. Test Your Soil: Conduct a soil test to determine pH levels and nutrient content.
  2. Amend the Soil: Depending on your soil test results, you may need to add lime to raise pH or sulfur to lower it. Incorporate organic matter such as compost or well-rotted manure to improve soil structure and fertility.

Location

Select a sunny location for planting; amaranth requires at least six hours of full sun each day. Ensure the area is free from weeds that may compete with amaranth for nutrients.

Planting Amaranth

When to Plant

In Pennsylvania, amaranth is best planted after the last frost date in spring (typically around mid to late May) when the soil temperature reaches at least 60°F (15°C).

How to Plant

  1. Direct Sowing: Sow seeds directly into the garden bed at a depth of about ¼ inch (0.6 cm) and space them approximately 12 inches apart.
  2. Seedling Start: Alternatively, you can start seeds indoors 4-6 weeks before the last frost date and transplant seedlings outdoors once they have developed two sets of true leaves.

Watering

After planting, water gently but thoroughly to ensure seed-to-soil contact. Continue to keep the soil consistently moist but not soggy until the plants establish roots.

Caring for Amaranth

Watering Schedule

Once established, amaranth plants require moderate watering—about 1 inch per week during dry spells—especially during flowering and seed development phases.

Fertilization

While amaranth can thrive in less fertile soils, incorporating a balanced fertilizer (like a 10-10-10 NPK) during the growing season can boost growth and yield.

Pest Control

Although pest problems with amaranth are relatively minimal, keep an eye out for aphids or spider mites:

  1. Manual Removal: For minor infestations, manual removal is often sufficient.
  2. Natural Predators: Encourage beneficial insects like ladybugs to help control pest populations naturally.

Harvesting Amaranth

When to Harvest Leaves

If you’re growing amaranth primarily for its leaves:

You can harvest leaves throughout the growing season until frost hits.

When to Harvest Seeds

For those growing amaranth for its seeds:

  1. Monitor flower heads as they begin to change color from green to brown.
  2. Harvest when most of the flowers have dried out and turned brown.
  3. Cut the flower heads off and place them in a paper bag to finish drying.
  4. Once fully dry, gently rub the heads together over a bowl or container to release the seeds.

Storing Amaranth

Seed Storage

Store harvested seeds in an airtight container in a cool, dark place away from moisture; they can remain viable for several years when stored properly.

Leaf Storage

Freshly harvested leaves can be stored in a plastic bag in the refrigerator for up to one week or blanched and frozen for longer-term use.

Conclusion

Growing amaranth in Pennsylvania can be a rewarding experience, yielding nutritious seeds and delicious greens while adding visual interest to your garden landscape. With careful planning—from seed selection through harvesting—you can successfully cultivate this ancient superfood right in your backyard. By following these guidelines, not only will you enjoy homegrown amaranth but also contribute positively toward sustainable gardening practices in your region.
