Common name : Alocasia
Scientific name : Alocasia
Family : Araceae
Category : Indoor
Type of plant : Perennial
A beautiful tropical plant named Alocasia that requires high heat all year, and a very humid atmosphere. It is therefore cultivated in our colder climates in heated greenhouse or verandas. Alocasia is a relative of the arums, besides its fruiting in red berries stuck on a raised candle - a spathe - is very similar. The leaves emerge directly from the rhizome, are borne by a cylindrical petiole, and are elongated, sagitted - like an arrowhead - or oval. Some species have cut leaves, or colored ribs.
Alocasia is a cousin of arums. Its fructifications in red berries glued on an erect candle - a spathe - is very similar to that of arums.
The leaves emerge directly from the rhizome, and are borne by a cylindrical petiole. Some species have cut leaves or colored veins. All are green, more or less dark, whole, elongated, sagittal - like an arrowhead - or oval.
Plant my alocasia
For the location, you need a bright place protected from direct sun - especially the afternoon - and away from the heaters. Provide a lot of moisture to your alocasia - bathroom, tropical greenhouse, porch can suit.
Alocasia is a plant with great development, so choose a large pot - minimum 5 liters. For the planting use potting soil for indoor plant - rather woody - or a beautiful compost well decomposed very woody too, very draining. Water copiously with non-calcareous water at planting.
Water my alocasia
Water often and abundantly in the summer, with non-calcareous and non-chlorinated water.
In winter, let the top soil dry slightly before watering.
Put outside my alocasia
In summer, take out your alocasia and place it in the shade.
You should shelter it back before the cold returns.
Shelter my alocasia
Bring your alocasia inside at the end of the summer, find it a bright place protected from direct sun - especially in the afternoon - and away from the heaters.
Fertilize my alocasia
In summer, pour every 2 weeks a liquid fertilizer for green plants - or a good compost juice diluted to 1/10 if you have some!
A slow-release fertilizer is possible ...
Stop every fertilizing in the fall, and until the end of the following spring.
Repot my alocasia
At the end of the winter every 2 or 3 years, repot your alocasia in a pot slightly larger than the current one, with compost for indoor plants. If you have a beautiful compost well decomposed very woody, very draining, it works too.
Spray my alocasia
In dry weather, spray your plant with soft water, clean the dust on the leaves: it will be all the more beautiful!
