Fertilizing Your Amaranth Plant: The Dos and Don’ts

Amaranth is an ancient grain that has been cultivated for thousands of years. With its nutritious leaves and seeds, vibrant flowers, and ease of growth, it’s no wonder amaranth is becoming increasingly popular to grow in home gardens. Proper fertilization is key to growing a healthy and productive amaranth plant. Here’s a comprehensive guide on the dos and don’ts of fertilizing your amaranth.

Getting to Know Amaranth’s Nutrient Needs

Before applying fertilizer, it’s important to understand what nutrients amaranth requires for optimal growth. Amaranth needs a good balance of nitrogen, phosphorus, and potassium (NPK) as well as secondary nutrients like calcium, magnesium, and sulfur.

• Nitrogen promotes lush, green foliage and influences seed production. Amaranth leaves need adequate nitrogen while the seeds require less.

• Phosphorus supports strong root growth and development It also aids in flower and seed production.

• Potassium increases disease resistance and helps the plant tolerate stress. It also assists in photosynthesis.

Amaranth thrives in soil with a pH between 6.0-7.5. Testing your soil’s pH before fertilizing allows you to identify and correct any imbalances.

The Dos: Proper Fertilizing Techniques

Here are some dos to follow when fertilizing amaranth for healthy growth:

Use organic fertilizers: Organic options like compost, manure, fish emulsion, and bone meal release nutrients slowly. This provides amaranth with a steady diet versus getting one large influx of nutrients from chemical fertilizers.

Fertilize during the growing season: Amaranth needs fertilizer when actively growing, so focus applications from spring until fall. Fertilize young plants when they are 6 inches tall and again every 2-3 weeks during the growing season.

**Apply fertilizer evenly:**Scatter fertilizer around the base of plants, keeping it 6 inches away from stems to prevent burning. Gently work it into the top few inches of soil.

Use foliar feeds: Spraying liquid fertilizer directly on leaves gives amaranth an immediate nutrient boost. Use foliar feeds to correct deficiencies quickly.

Water after fertilizing: Watering helps incorporate fertilizer into the soil. Avoid heavy watering that can lead to runoff.

Adjust amounts based on growth stage: Young and old plants have different needs. Use less fertilizer on seedlings and small plants. Increase amounts as plants mature.

The Don’ts: Mistakes to Avoid

Some common fertilizing mistakes can actually harm amaranth plants. Here are some key don’ts:

Don’t over fertilize: Too much fertilizer can build up in the soil and cause salt damage, burning leaves and roots. More is not always better.

Don’t fertilize too close to stems: Applying fertilizer right next to stems risks burning the plant. Leave a 6 inch perimeter around each plant.

Don’t use pure chemical fertilizers: While they provide a quick burst of nutrients, chemical fertilizers can accumulate in the soil and leach into groundwater over time.

Don’t fertilize after mid-summer: Amaranth doesn’t need much fertilizer once seed production starts. Excess nutrients late in the season can prevent plants from hardening off for winter.

Don’t fertilize stressed plants: Only fertilize healthy, actively growing amaranth. Fertilizing plants under stress from pests, disease, overwatering, or other problems can damage them further.

Frequently Asked Questions About Fertilizing Amaranth

How often should I fertilize amaranth plants?

Fertilize amaranth every 2-3 weeks during the active growing season. Avoid over fertilizing.

What’s the best organic fertilizer for amaranth?

Compost, fish emulsion, manure, and bone meal are excellent organic options. They slowly release a variety of key nutrients amaranth needs.

When should I start fertilizing my amaranth?

Begin fertilizing amaranth once seedlings are about 6 inches tall. Young plants need less fertilizer than mature, full-grown amaranth.

Is fertilizing amaranth seeds necessary?

Not usually. Seeds contain enough nutrients to sustain new seedlings. Wait until plants are established before fertilizing.

Can I use coffee grounds to fertilize amaranth?

Yes! Coffee grounds contain nitrogen, potassium, and other nutrients. Mix them into soil, but don’t overdo it as too much can make soil acidic.

Is Epsom salt good for amaranth?

Epsom salt contains magnesium, which amaranth needs. However, use it sparingly by dissolving 1 tablespoon per gallon of water and spraying leaves. Too much salt can burn plants.

Conclusion

With the proper dos and don’ts, fertilizing amaranth doesn’t have to be complicated. Test soil, use organic fertilizers, feed plants regularly during the growing season based on their maturity, and avoid common mistakes like over-fertilizing. Paying attention to amaranth’s needs and growth stages ensures your plants get the nutrients they require for bountiful leaves, flowers, and seeds.
