How to grow Alocasia macrorrhizos (giant taro) hydroponically? A detailed guide to the complete steps
1. Take a potted plant directly and wash it clean; for hydroponics, it is best to choose an Alocasia macrorrhizos with an attractive plant shape and many branches.
2. Cut the plant back from the base at about five cm above the soil surface, and use stem cuttings to promote rooting.
3. Take the small leaf-bearing Alocasia macrorrhizos that sprouts around the tuber.
4. When the fruit ripens in autumn, harvest the orange-red seeds and sow them immediately after harvesting to form small plants.

Can Alocasia macrorrhizos be grown hydroponically? What are the hydroponic methods for Alocasia macrorrhizos? Alocasia macrorrhizos is a common potted green plant; the editor has seen both soil-grown and hydroponic Alocasia macrorrhizos. Personally, I still prefer hydroponic Alocasia macrorrhizos, because the leaves are glossy and clean, and you can usually also enjoy watching the roots of the Alocasia macrorrhizos grow. Seeing the roots of the Alocasia macrorrhizos become more numerous and longer brings great delight. The correct way to start hydroponic Alocasia macrorrhizos is as follows:

Daily care of hydroponic Alocasia macrorrhizos
(1) The stems and root system of Alocasia macrorrhizos are relatively loose in tissue and have high water quality requirements; be careful to keep the water clear and sanitary, otherwise the stems and root system are prone to rot.
(2) In hot summer, increase the frequency of water changes, and require air humidity of no less than 60%. Spray water frequently to create a relatively cool and humid environment for it. In winter, to keep its leaves dark green, generally spray warm water once a week.
(3) The water level just needs to cover 2/3 of the root system; often clean the inner wall of the container to avoid the growth of algae.
(4) The sap in the stems and leaves of Alocasia macrorrhizos is toxic; pay attention during care and management, do not let it enter the mouth, and contact with the skin will cause itching and redness and swelling, so it should be rinsed with water promptly, or wearing plastic gloves while handling makes it safer.

Material selection for Alocasia macrorrhizos
Choose an Alocasia macrorrhizos that grows well and has no pests or diseases as the mother material for hydroponics. Clean up the old leaves and dead leaves on the stem, keeping only two or three new leaves. Loosen the potting soil, remove the plant from the pot, and then rinse the entire Alocasia macrorrhizos clean; it must not carry soil, first because it easily pollutes the water quality, and second because it carries pathogens, which easily causes root rot.
Planting Alocasia macrorrhizos into the container
Step 1
After cutting off all the soil-grown roots from the base of the rinsed mother Alocasia macrorrhizos, carefully check the stem for rot and pest damage. Use a small knife to dig out the rotten stem until you reach the woody part, and remove the rotten material and pests.
Step 2
According to the size and shape of the Alocasia macrorrhizos, fix it well with planting baskets of different sizes, immerse the entire planting basket in a 3%--5% thiophanate-methyl solution or carbendazim solution to disinfect for 5--10 minutes, and place it in a cool place to dry.
Step 3
Plant the dried mother Alocasia macrorrhizos together with the planting basket into a perlite rooting bed; through controlling the water, nutrients, temperature, light, etc. of the bed, primary roots can grow in about 10--15 days.
Induction of Alocasia macrorrhizos
When the primary roots grow to 2-3 cm long, they can be moved to the induction pool to induce water roots. At this stage, the dissolved oxygen content and EC value in the water and the adjustment of the nutrient solution ratio are related to the success or failure of the induction. When the water roots grow to a certain number and length, it means they have adapted to growing in water, and they can be placed in bottles for static hydroponics.
Water for Alocasia macrorrhizos
Alocasia macrorrhizos has high water quality requirements; be careful to keep the water clear and sanitary, otherwise the stems and root system are prone to rot. Choose unpolluted water with a pH value of 6-6.5; if using tap water, it should be left to stand for more than 1 day before use so that the chlorine in the water volatilizes.
Changing water for Alocasia macrorrhizos
When changing the water, gently rinse the plant's roots, remove the mucus on the roots, and at the same time cut off aged roots and rotten roots, and remove yellow and withered leaves appearing on the plant. When changing the water, clean the algae and scale on the vessel. Then, add fresh water to the vessel, but it should not be poured in all at once; it is best to stir for a while. When changing water and adding water normally, the water poured into the hydroponic vessel should not be too full; keep the water surface 2-5 cm below the plant stem base.
Fertilizing Alocasia macrorrhizos
Do not fertilize randomly in the water; choose special fertilizer for hydroponics. Easily soluble fertilizers such as urea and monopotassium phosphate can be used for foliar fertilization. The suitable fertilizer concentrations are: urea 0.1%, monopotassium phosphate 0.15%, ferrous sulfate 0.1%.
Root system of Alocasia macrorrhizos
When the root system grows too long and too dense, appropriately cut off old roots and shorten long roots to promote the sprouting of new roots and enhance root vitality. In addition, if the plant's roots rot, promptly cut off the rotten roots completely, change the water once every 1-2 days, and only return to normal care after the plant sprouts new roots.
