How to grow globe amaranth? Cultivation methods and precautions for globe amaranth

How do you grow globe amaranth? What are the cultivation methods and precautions for globe amaranth? Today we will describe the planting and cultivation techniques for globe amaranth. Globe amaranth is also known as yuanzaihua, zhirihong, and fireball flower. It is native to Brazil, but it is now commonly planted in areas south of the Yangtze River in China. Globe amaranth is a very good medicinal plant and has the effect of relieving cough and calming asthma.

Cultivation methods for globe amaranth

Globe amaranth likes sunlight and does not have very high environmental requirements. It is strong by nature, early-growing, tolerant of dry heat and drought, not cold-tolerant, and suitable for loose and fertile soil. Its flowering period is from July to October.

Light: The seedbed for globe amaranth should be set up in a covered place. In summer, the shading rate should reach 80% to 90%, and in spring and autumn, a shading rate of about 70% to 80% is sufficient.

Temperature: The optimum temperature for rooting of globe amaranth cuttings is between 20°C and 25°C. If the temperature is lower than 18°C, rooting will be affected to a certain extent, and the survival rate will be low. When the temperature is lower than 10°C, the cuttings will suffer frost damage.

Watering: When growing globe amaranth, water at the right time, in the right amount, and reasonably, according to changes in the weather. Generally, water less or not at all on cloudy and rainy days. When the temperature is high and evaporation is large, water more; otherwise, water less. When watering, water thoroughly. Usually pay attention to whether there is water accumulation in the pot. If water accumulation is found in the pot, deal with it in time, otherwise it will cause root rot and yellowing leaves, leading to plant death.

Fertilization: About 7 to 10 days after globe amaranth is planted, the first fertilization can be done with a 0.5% concentration urea solution. After that, fertilize once a week, and the concentration can gradually increase or add 0.6% to 1.0% compound fertilizer. After fertilizing, immediately sprinkle water lightly on the leaf surface to avoid fertilizer damage to the leaves. During the growing period, apply less nitrogen fertilizer and more fertilizer based mainly on phosphorus and potassium fertilizer, such as chicken manure and peanut meal.

Precautions for globe amaranth

Globe amaranth is relatively sensitive to water and fertilizer. During the growing period, it should not be watered or fertilized too much, otherwise it will cause excessive growth of stems and leaves and sparse flowering. In the plum rain season, if there is too much soil moisture, the plant is prone to waterlogging and the whole plant may die. During high summer temperatures, air humidity should not be too high, and the pot soil must not accumulate water, otherwise both are unfavorable to the growth and flowering of globe amaranth. Globe amaranth is a light-loving flower and needs sufficient sunlight during growth and flowering. If the cultivation site has insufficient sunlight, the leaves will be soft, the internodes long, the flower buds reduced, the flowers thinner, and the flower color lighter. On the contrary, with sufficient sunlight, the internodes are dense, the flower color is bright, the flowers are large, and flowering is continuous. The soil requires fertile, loose, and well-drained sandy soil.

The above are the cultivation methods and precautions for globe amaranth. As long as you cultivate according to the above conditions, I believe you will definitely grow high-quality globe amaranth. So growers of globe amaranth, get started right away!

Cultivation methods and precautions for globe amaranth: how to grow globe amaranth

Globe amaranth is also called zhirihong and fireball flower. Globe amaranth is suitable for loose and fertile soil and likes sufficient sunlight and a hot, dry climate. So, how do you grow globe amaranth? This article mainly introduces the cultivation methods and precautions for globe amaranth. Let's take a look.

I. Cultivation methods for globe amaranth

1. Soil management

Zhirihong is strong by nature and easy to cultivate. It does not have strict soil requirements, but it grows best when planted in deep and fertile sandy loam.

2. Fertilization management

In addition to using decomposed chicken manure as base fertilizer at planting time, during the vigorous growth stage, a thin liquid fertilizer rich in phosphorus and potassium should also be applied once every half month.

3. Watering management

Globe amaranth likes a slightly moist, somewhat dry soil environment and is relatively drought-tolerant. Therefore, after the seedlings grow new leaves again, watering should be properly controlled; after the plant's flower buds differentiate, appropriately increase the amount of watering to facilitate normal flower growth.

4. Light management

Globe amaranth likes an environment with sufficient sunlight. During cultivation, ensure that the plant receives no less than 4 hours of direct sunlight per day. The cultivation site must not be too shaded, otherwise the plant will grow slowly and the flower color will be dull.

5. Pruning management

When the seedlings are 15 cm tall, pinch once to promote branching. After that, decide whether to pinch a second time according to growth conditions. When shaping and pruning, attention should be paid to rounding the plant into shape so that globe amaranth has higher ornamental value. After the plant takes shape, pinching the branches can effectively control the flowering period.

6. Flowering period management

After the flowers open, just keep the pot soil slightly moist. Be careful not to spray water on the flowers, stop topdressing fertilizer, and maintain normal light. After flowering, prune in time so that new branches can grow and bloom again.

7. Disease control

Globe amaranth is prone to damping-off disease during the seedling stage. For control methods, 5-6 days before sowing, treat the seedbed with a 1500-fold solution of Lijuning; a 1000-fold solution of Lijuning can also be used to drench the roots of diseased plants.

II. Precautions for growing globe amaranth

Globe amaranth does not have strict environmental requirements. It likes sunlight, is strong by nature, early-growing, tolerant of dry heat and drought, not cold-tolerant, afraid of waterlogging, and likes loose and fertile soil. The optimum growth temperature is 20°C-25°C, and it also grows well within the range of 35°C-40°C. In winter, when the temperature is below 10°C, the plant grows poorly or suffers frost damage. It is strong by nature and tolerant of pruning. After flowering, pruning can cause new branches to sprout again and continue flowering.

Globe amaranth has brilliant flower colors and is very gorgeous when in bloom. It is very suitable for planting in courtyards and other places. There are also potted types of globe amaranth used to decorate indoors, but their growth time is slower. The cultivation methods and precautions for zhirihong are introduced here. We hope they are helpful to everyone.
