How do you care for Alocasia amazonica so it grows vigorously?
Caring for Alocasia amazonica well is actually not very difficult, as long as we master certain methods. Below, let's look at how to care for Alocasia amazonica from several different aspects~
How to care for Alocasia amazonica
Alocasia amazonica is a plant that loves warmth, moisture and plenty of sunlight. It grows in shaded, humid understory environments with abundant and evenly distributed rainfall. Deep, well-drained, fertile and loose sandy loam is most suitable. It fears waterlogging, can be grown continuously but is best rotated.
1. Planting time for Alocasia amazonica
The best planting time is April and May, and the temperature should be kept above 20-25°C, which is beneficial for seedling growth. After planting, water once every 2 to 3 days to keep the soil moist. Do not overwater, to avoid root rot and stem rot. On the cultivation methods and precautions for Alocasia amazonica: Alocasia amazonica is commonly propagated by division. Generally, when temperatures are higher in spring and summer each year, split the underground tubers of densely tillered plants along the separation points of the tubers, so that each part has 2-3 plants, then pot and plant them separately.
You can also dig out the underground tubers before new buds sprout in spring, cut the tubers into sections, disinfect and preserve the wounds with plant ash or sulfur powder, let them dry slightly, then wrap them in sphagnum moss, or place them in loose, aerated and well-drained soil so they grow adventitious roots and sprout new buds.
2. Suitable soil for Alocasia amazonica:
For potted Alocasia amazonica, use loose, well-drained and aerated soil rich in humus. Generally, an equal mix of leaf mold, garden soil and river sand can be used as the substrate. April to September is its vigorous growth period, when the soil should be moist and the air humidity relatively high, and sufficient water should be given. This plant is easy to grow; ordinary soil can be used for the potting mix, but better is garden soil plus one third humus soil, plus one third river sand or coal cinder, mixed with a little bone meal.
3. Suitable temperature for Alocasia amazonica
The optimum growth temperature is 22-30°C. After November, when the temperature falls below 20°C, the plant grows slowly or stops growing; the aboveground parts begin to turn yellow, wilt and wither, and it enters dormancy in winter. Alocasia amazonica is easy to cultivate and is not strict about soil, fertilizer or water; it tolerates poor soil and drought, and can make full use of various idle hillside plots for planting. If cultivation and management conditions are good, it can achieve high yields year after year.
Do not expose it to the scorching sun, to avoid large areas of sunburn on the plant. On the cultivation methods and precautions for Alocasia amazonica: the growth temperature is 20-30°C, and it can tolerate a low of 8°C. In summer, as long as the soil is kept moist, water is sprayed frequently and shade is provided, it can still grow normally. In winter, the indoor temperature must not be below 5°C. Alocasia macrorrhizos is an understory plant of tropical rainforests, so its growth requires high humidity, and scattered light is best.
4. Watering
In spring and autumn, water about once every 15 days; in summer, once every four or five days, avoiding the hottest midday period.
It especially loves moisture. During the growing season, not only should the potting soil be moist, but the air humidity should also be no less than 60%. Especially during the high-temperature period in summer, when leaf water evaporation is high, the water requirement is greater. If water is lacking, the leaves easily wilt. During high summer temperatures, strengthen spraying to create a relatively cool and moist environment for it. If placed in an indoor air-conditioned hall, ensure the potting soil is moist and also spray the leaves from time to time. Therefore, spray the leaves frequently while keeping the environment humid, but be sure to avoid water accumulating in the pot, otherwise it will cause root rot.
In autumn, when the temperature is below 15°C, the growth of Alocasia amazonica stalls and it enters a dormant state, and the aboveground leaves gradually wither. On the cultivation methods and precautions for Alocasia amazonica: at this time, minimize watering, place it in a warm, windless and dry place, and keep the potting soil appropriately dry (only slightly moist) to help it overwinter safely. If humidity is high and the temperature is low, the tubers rot very easily.
If the indoor temperature in winter cannot reach 15°C, watering should be controlled, otherwise it easily causes root rot in the plant. Generally, spraying warm water once a week is enough to keep its leaves dark green.
Normally, do not water too much, and try to avoid water droplets touching the leaves. Provide more light, and every three or four days turn the pot in another direction so that all sides of the lotus-like rosette receive light, which will make it grow flat with enticingly green leaves. But do not expose it to scorching sun.
5. Light conditions
Throughout its growing period, Alocasia amazonica requires semi-shade conditions. If the light is too strong, the leaf color easily becomes dull and sunscald may occur; but if the light is too weak, it also easily becomes leggy, with thin plants that topple easily. During the vigorous growth period, apply 1-2 times a month of dilute liquid fertilizer according to the plant's growth, and add extra phosphorus and potassium fertilizer, to help the stems stand upright and grow robustly, and also to help the underground tubers grow plump and resist cold for overwintering.
6. Pruning and shaping
If you want to grow Alocasia macrorrhizos indoors as a compact and delicate plant, then simply wait until its seedlings grow to about one chi and are suitable for placement at home, then immediately spray the whole plant with a 2% paclobutrazol solution. On the cultivation methods and precautions for Alocasia amazonica: the stems and leaves that grow afterward will be no taller than 40 cm, and the leaves will be thick and fleshy with high ornamental value. Spraying once about every half a year can achieve a good height-control effect.
For propagation, you can use the small plantlets that grow between the leaves. Once the plantlets are a bit bigger, cut them off, let the cut dry for 1-2 days, and plant them in soil, where they will root and become new plants. Whether they are new plants or old plants bought without a pot, do not water them right after planting; at most spray a little water on the leaves.
