Amaryllis Care Guide

Amaryllis (Hippeastrum spp.) are striking, elegant flowering plants known for their bold, trumpet-shaped blooms and vibrant colors. They’re a popular choice for holiday décor but can also be enjoyed year-round with proper care. This guide will provide everything you need to know to grow, maintain, and enjoy healthy amaryllis plants. These tropical plants are native to South America, typically grown from bulbs. They are prized for their showy flowers that can range in color from red, white, pink, orange, or even bi-colored varieties. Amaryllis are easy to grow and make great indoor plants or gifts during the holiday season.

Planting and Watering

Amaryllis can be planted in soil or water, depending on your preference.

Planting in Soil

  1. Choose a well-draining potting mix.

  2. Select a container with drainage holes.

  3. Plant the bulb with the pointed end facing up and the top 1/3 of the bulb exposed above the soil.

  4. Water thoroughly after planting.

Planting in Water

  1. Use a container that allows you to place the bulb in water without submerging it completely.

  2. The base of the bulb should be just touching the water.

  3. Add pebbles to support the bulb and keep it upright if needed.

  4. Change the water every few days to prevent bacterial buildup.

Light

Bright, indirect light is ideal for amaryllis. A south- or east-facing window is perfect.

  1. Avoid direct sunlight, as it can scorch the leaves or flowers.

  2. If natural light is insufficient, supplement with grow lights.

Water

Watering needs depend on the growth stage:

  • After planting: Water when the soil dries out or when the water level drops.

  • During active growth: Keep the soil moist but not soggy. Amaryllis dislike overwatering.

  • Once flowering begins: Reduce water slightly to prolong the blooms' life.

  • Always ensure that any container has proper drainage to prevent root rot.

Temperature & Humidity

Optimal temperature range: 65–75°F (18–24°C) during the day and no lower than 50°F (10°C) at night.

  • Avoid placing your amaryllis near drafts, cold windows, or heaters, as sudden temperature changes can stress the plant.

  • Amaryllis prefer average indoor humidity. If your indoor air is very dry, mist the plant lightly or use a pebble tray with water.

Fertilizer

Feed your amaryllis once a month with a balanced houseplant fertilizer (e.g., 10-10-10 or 20-20-20) during the growing season. Avoid overfeeding. Stop fertilizing after the plant has finished blooming.

After-Flower Care (Post-Bloom)

Once your amaryllis has finished flowering:

  1. Continue watering and allowing foliage to grow: Keep the leaves healthy, as they are needed to recharge the bulb for the next growing season.

  2. Cut back the foliage in late spring or early summer: Once the leaves begin to yellow, cut them back to about 1 inch above the soil.

  3. Dormancy: Allow the bulb to rest by reducing watering and placing it in a cool, dark location. This rest period allows the bulb to store energy for the next growing cycle.

Re-Planting for Next Season

After the dormancy period:

  1. Bring the bulb back out, clean off any dead material, and plant it in fresh soil or water.

  2. Resume watering and place it in bright, indirect light to encourage new growth.

  3. Expect blooms within 6–8 weeks.

Common Issues & Troubleshooting

Yellowing Leaves

  • May indicate overwatering, underwatering, or low light.

  • Solution: Adjust watering, ensure adequate light, and check for root rot.

No Flowers

  • Could be due to insufficient light, lack of nutrients, or the bulb is too young or stressed.

  • Solution: Ensure bright light, adjust fertilization, and check for proper watering.

Drooping Stems

  • Drooping can occur due to under-watering or weak growth.

  • Solution: Water appropriately and support the plant if necessary.

Pests & Diseases

  • Common pests include aphids or spider mites.

    • Treat with insecticidal soap or neem oil if needed.

  • Root rot may occur if the plant is overwatered or sitting in poor drainage conditions.

Propagation

Amaryllis are typically propagated by dividing bulbs after dormancy. Bulbs naturally produce offsets that can be separated and planted to grow new plants.
To propagate:

  1. Wait until the bulb has completed its growth cycle.

  2. Separate the small offsets from the parent bulb.

  3. Replant the offsets in fresh soil and care for them as you would a regular amaryllis bulb.

Tips for Success

  1. Always plant bulbs that feel firm and are free of rot or damage.

  2. Rotate the pot occasionally to ensure even light distribution and growth.

  3. Consider staking taller stems during their bloom cycle to prevent them from toppling over.

  4. Avoid exposing amaryllis to extreme drafts, heat, or sudden environmental changes.
