Detailed Guide to Growing Alocasia macrorrhizos from Seed

When the fruit ripens in autumn, collect the orange-red seeds and sow them immediately, or dry and store them to sow after spring the following year.

Can Alocasia macrorrhizos be grown from seed?

The seeds of Alocasia macrorrhizos

Alocasia macrorrhizos is a wild plant, a tropical plant. Alocasia macrorrhizos likes to grow in warm, humid and even semi-shaded environments, so it is relatively precious, and its seeds are not easy to obtain.

Growing Alocasia macrorrhizos from seed

Sowing time

The most suitable sowing time for Alocasia macrorrhizos is every spring, when the weather is warm and humid; the most suitable germination temperature is around 5-8°C.

Preparation before sowing

Soak the seeds of Alocasia macrorrhizos in water for about one day, then gently rub off the flesh with your hands, and disinfect the growing medium while waiting to sow.

Sowing process

Sow the seeds of Alocasia macrorrhizos evenly one by one in the growing medium, then cover with a layer of sandy soil. After sowing, be sure to soak the pot or spray with water to ensure sufficient moisture.

Work after sowing

Place Alocasia macrorrhizos in a spot with good light, keep the temperature at around 30°C, and keep the soil moist.

Notes on growing Alocasia macrorrhizos

Although Alocasia macrorrhizos is toxic, it can be grown safely at home, but keep a certain distance and do not handle it casually.

How to propagate Alocasia macrorrhizos: propagation methods for Alocasia macrorrhizos

How to propagate Alocasia macrorrhizos? There are generally 4 propagation methods for Alocasia macrorrhizos: stem cutting, seed sowing, division and root division. Below, the editor introduces the propagation methods for Alocasia macrorrhizos in detail.

1. Division propagation of Alocasia macrorrhizos

Alocasia macrorrhizos is a plant that is relatively easy to propagate. Every summer and autumn, the tubers sprout small Alocasia macrorrhizos with leaves. When new shoots grow, division can be carried out together with repotting and changing the soil. But note that the divided shoots must not be too small; they can be separated when they grow to about 7 or 8 cm. During the growing season, many seedlings often sprout from the base of Alocasia macrorrhizos; when they grow to 3-4 true leaves, they can be dug out and planted as new plants.

2. Stem cutting propagation of Alocasia macrorrhizos

Stem cutting propagation of Alocasia macrorrhizos is suitable in all three seasons of spring, summer and autumn. Cut a stem segment or terminal bud of about 10 cm as a cutting, plant it directly in the potting soil or insert it in a cutting bed, and water appropriately, and it can become a new plant. During cutting, keep the growing medium (6 parts sand : 4 parts garden soil) moist, and at the same time increase air humidity; in about 7-10 days many sturdy roots will grow. During the cultivation of old plants, because of the shady and humid environment or spraying the leaf surface morning and evening every day in summer and autumn, a few new shoots occasionally sprout on the old stems, and many aerial roots attach to them; these can be broken off from where the daughter plant meets the mother plant and potted up for planting.

3. Seed propagation of Alocasia macrorrhizos

When the fruit ripens in autumn, harvest the orange-red seeds; remove the red flesh of the Alocasia macrorrhizos fruit to obtain the seeds. Sow immediately after collecting, or dry and store them to sow after the following spring. When planting, open-field drilling or dibbling can be used; with appropriate watering and shading, they can be made to germinate.

4. Root division propagation of Alocasia macrorrhizos

Root division propagation of Alocasia macrorrhizos is very simple: just dig out the small bulbs that naturally separate from the roots of Alocasia macrorrhizos and plant them separately.
