How to Grow Amaryllis? Detailed Guide to Cultivation Methods and Precautions

The flowers of the amaryllis are charming and gorgeous, and when in bloom they are accompanied by a refreshing fragrance, giving them high ornamental value and making them very endearing. As an ornamental plant, the amaryllis naturally has stricter requirements for its beauty, but often many people care for it improperly, causing the amaryllis to lose its “charm.” Let's learn about it together below.

How to Grow Amaryllis

1. Choosing the soil

Amaryllis is planted in a relatively short pot, and in a limited space, the choice of soil is very important. The soil should preferably be loose, well-draining, acidic soil. Here is a mixed soil recommendation: mix peat, perlite, and vermiculite in a 2:1:1 ratio. The various materials are easy to find; just buy them directly from a flower shop. Add a small amount of superphosphate to the mixed soil as a base fertilizer.

2. Planting depth

Once the potting soil is ready, only planting remains. When first planted, at least more than half of the bulb should be exposed, mainly to observe the growth condition of the bulb and prevent rot. Wait until the bulb grows new leaves, then cover it with a layer of soil so that 1/2 or 1/3 of the bulb is exposed above the surface.

3. Watering

Water immediately after planting, watering thoroughly. After the potting soil dries, water again to keep the soil moist. As for topdressing, do not fertilize before the bulb grows leaves.

4. Placement environment

After planting, place the pot on a well-ventilated shaded balcony, keeping the temperature at 10-15 degrees C to facilitate rooting. Two weeks later, move the plant to a high-temperature spot at 20-25 degrees C for care.

Amaryllis Cultivation Methods and Precautions

I. Cultivation methods

1. Soil

Amaryllis requires loose, fertile soil with good drainage, and the pH value should be kept between 5.5-6.5. Usually the potting soil can be prepared by mixing decayed fertile soil, leaf mold, and sandy soil. The better the soil, the more vigorous the amaryllis grows, and the more gorgeous the flowers.

2. Watering

Amaryllis requires relatively moist growing soil, so how to water is very important. Watering should follow the principle of watering when dry and stopping when wet; when watering, water thoroughly, but avoid excess moisture. Usually, if indoor humidity is adequate, water once a week. If the indoors is dry, spray frequently to increase humidity.

3. Sunlight

Amaryllis likes to grow in sunlight, and can be exposed to appropriate direct sunlight, 2-3 hours a day is enough, not too long. In summer at noon or in weather with strong sunlight, try to move the plant indoors to a bright, well-ventilated windowside without direct strong light.

4. Temperature

Amaryllis likes warmth and is not cold-tolerant. In summer care, avoid heat, and keep the temperature at 18-22 degrees C. In winter dormancy, the environmental requirements are lower; as long as the temperature is above 5 degrees C, it can pass the winter safely, and it is enough to move it indoors for care.

5. Fertilizing

The growth of amaryllis requires sufficient nutrients, especially during the growing period when timely topdressing is needed. Generally, apply decayed cake fertilizer once every 15 days to promote flowering. After flowering, reduce fertilizing to once every 20 days to promote the enlargement of the bulb.

II. Precautions

Amaryllis is a bulb flower, and the health of the roots is related to the growth of the whole plant. Appropriately supplementing potassium fertilizer is beneficial to the development of new bulbs and the enlargement of old bulbs.

Hydroponic Method for Amaryllis

1. Selecting the bulb

Whether hydroponic amaryllis succeeds depends on the selection of the bulb. Usually choose bulbs over 3 years old (bulb size about 6 cm). After autumn and before frost, cut off the leaves or let them turn yellow naturally and then remove them, and appropriately control water to promote dormancy, letting the bulb rest fully in winter, which is favorable for flowering.

2. Planting

In spring, that is, after the bulb's winter dormancy, soak the bulb in a potassium permanganate solution, remove old roots and other impurities, and place it in a container for cultivating narcissus. The water should cover 1/3 of the bulb, and place a little coarse sand or small stones at the bottom of the container, which can better fix the newly grown root system. If the hydroponic plant is used as a wall hanging, no sand needs to be placed at the bottom of the container.

3. Transplanting

When the amaryllis bulb has grown many roots, reaching 0.5 cm, the plant can be moved to a clean hydroponic container (hydroponic beginners should try to choose professional containers, which are easier to grow). A proper hydroponic container will hold the plant upright; the water should not be too deep, and it is best to submerge half of the bulb. After transplanting, place it in a place with sufficient sunlight and good ventilation.

Key Points for Caring for Hydroponic Amaryllis

1. Temperature

The most suitable temperature for amaryllis growth is 20-25 degrees C. The temperature for potted and hydroponic cultivation is roughly the same, and the temperature should not be lower than 15 degrees C. At lower temperatures, amaryllis grows slowly and blooms later!

2. Change the water frequently

Regularly check the hydroponic container and change the water in time. In the early stage of hydroponics, change the water once every 2-3 days; after a month, change the water once every 4-5 days, keeping the water level in the container moderate and consistent.

3. Apply liquid fertilizer

To make the amaryllis grow stronger, when the leaves grow to 2-3 cm, promptly supplement fertilizer, topdressing once every 10-20 days. You can add urea solution or potassium dihydrogen phosphate solution when changing the water; try to choose liquid fertilizer, which the plant absorbs more easily.

Amaryllis is one of the very popular potted plants for beautifying the home environment, and it likes a warm, moist growing environment. One point to note during care is that it is not cold-tolerant and will enter a dormant period in winter; if cared for improperly, the amaryllis may “sleep and never wake up.”
