1. Globe amaranth seedlings
Globe amaranth, also known as round flower, hundred-day red, and fireball flower, is native to Brazil but is now widely cultivated in areas south of the Yangtze River in my country. Globe amaranth is a valuable medicinal plant, known for its cough and asthma-relieving properties.
Globe amaranth cultivation:
Globe amaranth is not particular about its environment, but prefers sunlight and hot, dry climates. It thrives in loose, fertile, and well-drained soil. Young seedlings are relatively robust. Seedlings can be planted densely in seedling trays and transplanted once before potting. Alternatively, seeding in plug trays can be done directly, with seedlings potted 4-6 weeks after emergence. Use pots with a diameter of 10-14 cm. The potting soil should be primarily peat, with garden soil preferably making up less than 15%. Using a completely soilless medium is also acceptable.
Globe amaranth is a sun-loving plant and should be kept out of direct sunlight except during the seedling stage. It can be grown in a sunny environment 2-3 weeks after potting. Sufficient sunlight promotes the formation of a round, low plant shape. During cultivation, care must be taken to maintain adequate spacing between plants to avoid crowding and poor plant shape due to lack of sunlight. Globe amaranth prefers warmth, tolerates sunlight, and is robust, adapting to loose, fertile, and well-drained soil. It has vigorous growth and is not demanding on fertilizer, water, or soil, making it easy to care for. Generally, apply one to two doses of light liquid fertilizer during the seedling stage. Excessive watering and fertilization during the growing season should be avoided, as this will cause excessive stem and leaf growth and infrequent flowering. Globe amaranth grows in warm seasons, so excessive fertilization is not recommended. Generally, apply a thin layer of fertilizer every 8-10 days, at the same time as watering. Add 1 gram of fertilizer per liter of water. A compound fertilizer with an N-P-K-mg ratio of 1.0-0.5-2.0-0.3 is preferred. The soil pH should be 6.0, and the EC value should be controlled between 0.8 and 1.2.
When the plant enters the later stage of growth, the phosphorus and potassium content can be increased, and the EC value can be slightly higher, to 1.6. During the growth period, timely irrigation and inter-cultivation should be carried out to keep the soil moist. Water should be drained in time during the rainy season. Apply liquid fertilizer rich in phosphorus and potassium 2 to 3 times during the flowering period, and the flowers will be lush and the leaves will be brilliant and colorful. After the withered flowers fade, do not let it set seeds. You can prune it to prevent it from setting seeds. It can still sprout new branches and bloom again in late autumn.
The branches of Globe amaranth grow in the axils of leaves. In order to promote a low plant and increase branches and flowers, “pinching” should be performed several times during the seedling stage. The focus of Globe amaranth cultivation and management is to cultivate a good plant shape. It is advisable to maintain sufficient sunlight, use dwarfing agent, and a negative DIF value (day temperature minus night temperature 2~3℃) to achieve this goal.
This flower is heat-resistant, but not cold-resistant and cannot withstand frost. After planting, keep potted globe amaranths moist and shaded. During the growing season, topdressing should be combined with watering. This flower is not particular about fertilizer, water, and soil, so care can be relatively minimal. Pruning after the remaining flowers have faded will allow new branches to sprout and bloom again in late autumn, but frequent light fertilizer application is necessary. Globe amaranths are native to my country and India. They are not particular about their environment, but prefer sunlight and hot, dry climates, and thrive in loose, fertile, well-drained soil. Precautions for Globe amaranths: Globe amaranths are sensitive to water and fertilizer. Avoid excessive watering and fertilization during their growth period, as this will cause excessive stem and leaf growth and infrequent flowering. Excessive soil moisture during the rainy season can cause waterlogging and plant death. During high summer temperatures, avoid excessive humidity and waterlogging in the potting soil, as these conditions are detrimental to the growth and flowering of globe amaranths. Globe amaranths are light-loving and require ample sunlight during their growth and flowering periods. If the cultivation site lacks sunlight, the leaves will be soft, the internodes will be long, the buds will be fewer, the flowers will become thinner, and the color will fade. Conversely, if there is sufficient sunlight, the internodes will be dense, the flowers will be brighter, the flowers will be larger, and the blooming will continue. Fertile, loose, and well-drained sandy soil is required.
The above are the cultivation methods and precautions for Globe amaranth. As long as you follow the above cultivation conditions, you will definitely produce high-quality Globe amaranth. Soil farmers who want to grow Globe amaranth should hurry up and get started.

Once the Globe amaranth seedlings have germinated evenly, move them to a sunny location for cultivation. When the seedlings grow to 5 to 8 cm in height, transplant them into 5-inch plastic pots or your own pots and cultivate them normally.
About cultivation and management: First, sunlight: Globe amaranth prefers full sunlight, at least six hours per day. Flowering is less common in part-day sunlight. A well-ventilated, high-temperature environment is recommended.
Watering: Water in the morning only, ensuring the soil is thoroughly irrigated and flows out of the drain. Water again by checking or feeling the soil surface with your hand. Water more frequently when it’s slightly dry. Sunlight intensity, air humidity, and temperature will influence whether you need to water quickly or slowly. You can observe the watering patterns described above for a while and learn how to water them.
Fertilizer: Do not fertilize after transplanting from a plug tray. Wait until the sunlight has returned to normal after two weeks of growth. Fertilize monthly from spring to autumn. Use an organic flowering fertilizer or a compound fertilizer.
Bud Picking: When the Globe Amaranth grows to 10 cm, pinch the top buds to encourage more branches.
3. Globe Amaranth Seedlings
I’m happy to answer your questions.
Seeds are collected in September-October, sowed in April-May, and transplanted in June. Globe amaranth seedlings grow slowly and should be sown in open-field seedbeds in spring from April to May. The optimum sowing temperature is 20°C to 25°C. Because the seeds are covered with hair, emergence is slow. To accelerate emergence, they should be pre-germinated before sowing. To achieve this, soak the seeds in warm water for one day or cold water for two days before squeezing out the moisture, letting them dry slightly. Then, mix with 2 to 3 times the amount of wood ash or fine sand to loosen the seeds for easier sowing. The seeds are large, about 400 seeds per gram. Ordinary sowing sites can be used, preferably sandy loam with ample sunlight, a high groundwater table, good drainage, and loose, fertile soil. Lightly cover with soil after sowing and maintain a temperature of 20°C to 25°C. Seedlings will emerge in about 10 to 15 days. After all seedlings have emerged, thin them out to allow them enough space to grow and avoid overlapping. After thinning, irrigate with a 1000x urea solution. After fertilizing, spray the leaves promptly to prevent fertilizer burn.

Globe amaranth can be propagated by sowing or cuttings.
Globe amaranth is propagated by seed. Seeds are collected in September-October, sown in April-May, and transplanted in June. The seeds are crisp, hairy fruits with perianths. Soaking the seeds in cold water for 1-2 days before sowing can increase the emergence rate. Let the soaked seeds dry slightly and mix with wood ash before sowing. After germination, top and prune the seedlings several times during the seedling stage to encourage more branching, flowering, and a shorter plant. Select plants with short, dense internodes for cultivation to maintain superior quality. During the growing season, apply moderate amounts of fertilizer and water, and pay attention to intertillage, weeding, and drainage during the rainy season.
5. Image of Globe Amaranth Seedlings
Globe Amaranth seeds are sown outdoors in March or April, evenly spreading the seeds on a well-prepared seedbed. Sow 2-3 seeds every 3-4 cm. Cover with about 2 cm of fine soil after sowing. After about 10-14 days, most of the seeds will germinate. Ensure the soil remains moist after emergence.
After the seedlings develop two pairs of true leaves, thin the seedlings after rain to ensure adequate growth space and nutrient intake.
Ensure close management during the growing season. Apply thin fertilizer 2-3 times in June and July. Prevent drought in summer and water frequently to keep the seedling bed moist, but be careful not to overwater. The seedlings can reach a height of 50-70 cm by winter. Well-grown plants can flower that same year. Prune the side branches and flowering branches in time after the leaves fall in winter, and transplant them in the early spring of the following year.
Extended information:
Maintenance
1. Increase light: It likes sunlight and must be placed in the sun outdoors during the growing season.
2. Timely watering: The potting soil should be kept moist in spring and winter. Water it once a day in the morning and evening in summer and autumn. During drought and high temperatures, the number of waterings can be appropriately increased each day. Use river water, well water, rainwater, and tap water stored for 2 to 3 days.
3. Fertilize regularly: Excessive fertilization of potted crape myrtle can easily cause the branches and leaves to grow too long. Lack of fertilizer will lead to thin and weak branches, yellow leaves, weak growth of the entire plant, and few or no flowers. Therefore, fertilize regularly. Apply more fertilizer during the peak growing season in spring and summer, apply less fertilizer after autumn, and no fertilizer is required during the dormant period in winter.
6. What causes Globe amaranth seedlings to rot?
1. Soil
Amaryllis should be cultivated in loose, fertile, sandy soil without any waterlogging. A mixture of well-rotted manure, leaf mold, and sand can be used.
2. Temperature
Amaryllis prefers a warm environment. In summer, the temperature can be slightly cooler, generally between 5°C and 7°F. During winter, Amaryllis is dormant, so a cool, dry environment is best, with temperatures not falling below 5°C.
3. Light
Amaryllis prefers sunlight, so it’s best to place it in a well-ventilated, bright, and sunny location. Avoid prolonged exposure to strong summer sunlight.
4. Watering
Water thoroughly, but avoid any waterlogging. Keep the soil slightly moist at all times. If you overwater, take measures to drain the soil to prevent rotting caused by waterlogging.
5. Pruning
Amaryllis grows quickly and leaves densely, so it’s important to promptly remove dead or diseased leaves to help healthy leaves grow better.
6. Precautions
To ensure the best growth of amaryllis, you must conduct pest and disease control. Spray with pesticides monthly, but avoid spraying at noon to avoid pesticide damage. Spray in the morning or afternoon on sunny days.
7. How to Care for Globe Amaranth Seedlings
It blooms in three years.
It is a precious environmentally protected plant in China. It is called the Globe Amaranth or the Itchy Tree because its bark trembles uncontrollably at the slightest disturbance. This is because its trunk is very sensitive to vibration. It is a deciduous tree in the Lythraceae family and can reach heights of up to 10 meters. The panicles grow at the tips of current year branches. These are large, 30 to 50 cm long, and contain dozens or more flowers. The flowers are about 3 cm in diameter and come in shades of white, violet, red, and purple. They bloom in summer and autumn, each inflorescence remaining open for about 50 days, and the entire plant blooms for up to four months. It is an excellent ornamental plant and also makes a good stump bonsai.
