How to grow a Bromeliad (Guzmania): Detailed Guide to Care Methods and Precautions

Growing a Guzmania (Bromeliad) not only beautifies your home environment but also carries auspicious meaning and positive energy. In addition, the Guzmania is believed to help dispel negative energy, so keeping a pot of Guzmania at home is very appropriate. Here, the editor offers you some growing methods for the Guzmania.

How to grow a Guzmania

The Guzmania likes a hot, humid, semi-shaded environment and can be kept year-round in a warm, bright room. In winter it can receive full sun; in spring and autumn it should get morning and evening light; in summer it should not be exposed to direct sunlight. With bright light, the leaf color is vivid.

The suitable growing temperature for the Guzmania is between 15~20°C, and the overwintering temperature must not be lower than 10°C. However, above 20°C is not favorable for the plant's dormancy and will affect its growth and flowering the following year.

Guzmania growing methods and precautions

1. Potting soil selection

The Guzmania requires soil rich in humus, loose, fertile, with good aeration and drainage, and slightly acidic (pH 5~5.5). At home, the most commonly used mix is leaf mold, river sand, a small amount of cake fertilizer, or decomposed chicken manure. Of course, to save trouble when repotting, you can buy it directly from a flower shop.

2. Repotting method

The Guzmania does not have a very long lifespan; usually plants 3~4 years old will bloom, gradually wither after flowering, and once withered the plant should be replaced. Therefore, it should be repotted once every 1~2 years to ensure a sufficient supply of nutrients in the soil.

3. Watering method

The Guzmania likes a humid environment, and during the growing period it needs relatively high air humidity and sufficient soil moisture. Keep the potting soil moist, and it is best to control the air humidity at 70%-80%.

The usual watering frequency is every 5~7 days. For some hard-leaved types that need less water, keep the pot surface relatively dry. For soft-leaved types that need more water, keep the potting soil moist at all times, ideally so that the surface soil never looks dry. Keep water in the leaf cup at all times; a lack of water in the leaf cup easily causes the plant to wilt.

After the beginning of autumn, the Guzmania's growth slows down, so watering and misting should be appropriately reduced. After entering the dormant period, watering should be controlled and the potting soil kept only slightly moist; do not water unless the potting soil is dry, as overly wet soil easily causes root rot. Keep the bottom of the leaf cup moist, but do not give too much water, lest it cause rot.

4. Fertilizing method

During the growing season, fertilize once every 10~20 days, using fermented cake fertilizer or chemical fertilizer. For chemical fertilizer, usually use nitrogen, phosphorus, and potassium, with the concentration controlled at 0.1%-2.3%. When fertilizing, try not to apply fertilizer to the center of the plant, to avoid causing harm. Fertilizing should be stopped during the flowering period, the dormant period, and in summer.

5. Light requirements

The Guzmania needs sufficient light to grow; control the daily light duration at 12~16 hours. With sufficient light, combined with high humidity and good ventilation, it will grow faster and better. The plant will become short, stout, and sturdy, with broad, short, stiff leaves and bright, beautiful flower colors.

6. Precautions

Humidity is very important for the Guzmania's growth; the suitable relative humidity is 50%-75%. Above 80%, ventilation should be strengthened, otherwise disease or leggy growth easily occurs. Below 40%, leaf tips easily wither, so regular misting is needed to retain moisture.

Guzmania care also depends on the variety. For light-loving varieties such as the variegated-leaf Guzmania, give more light and place it on a windowsill or balcony.

The quality of the water used for watering is also very important for the Guzmania. It likes to grow in acidic soil and requires water that is also weakly acidic; it dislikes salts, especially calcium salts and sodium salts.

The benefits of the Guzmania

1. The Guzmania creates a natural oxygen bar for you

The Guzmania is a plant of the Bromeliaceae family; among the bromeliad varieties, it is an ornamental bromeliad. As an ornamental bromeliad, the Guzmania can release oxygen at night. Most plants open their stomata during the day for photosynthesis and enter a sleep state at night with their stomata closed. Plants of the Bromeliaceae family are just the opposite; the technical term is crassulacean acid metabolism. Under this process, the Guzmania can absorb a large amount of carbon dioxide and release oxygen at night, so placing a pot of Guzmania at home means having a household oxygen bar.

2. The Guzmania is a symbol of happiness

The Guzmania is a very beautiful indoor potted plant that offers both flowers and foliage. It has a rosette-shaped plant form and bright, spike-shaped inflorescences, making it a darling of the flower market. Its especially bright red color suits people who love vitality. The Guzmania is considered a fine flower among flowers; grown in coordination with home furnishings, it adds a beautiful scenery. Imagine how pleasing it is to see such a brightly colored flower every day.

How to make the Guzmania bloom

A normal Guzmania needs 2~3 years of care before it blooms, and it basically blooms in autumn, then enters its winter dormant period after flowering. But often people want to control its flowering time and control their good fortune, which gives rise to the following flower-forcing technique:

First, stop fertilizing. When the Guzmania is growing relatively vigorously, stop fertilizing for half a month; basically it should go 1 month without fertilizer.

Second, pour an “ethephon solution” or “acetylene water solution” into its leaf cup. The prepared concentration is generally 1:1000 (control the concentration well, otherwise it will backfire). Just pour it 1 to 3 times.

Finally, when forcing flowers, control the temperature at 15~18°C; do not let it get too high. After one month, gradually increase fertilizer and water, and it will soon bloom.

A Guzmania is only truly a Guzmania once it blooms, so maintaining the Guzmania's flowering state is very important. The article contains methods for forcing flowers, with requirements, and friends who are willing to try can give it a go; it will not have any adverse effect on the Guzmania.
