Calathea ornata Sanderiana

Calathea ornata I like the article

Fertilization Calathea ornata
In the spring letís use a fertilizer every 15-20 days, melting it in the water which we use to irrigate; we can choose a fertilizer for flowering plants or green plants, rich with nitrogen and potassium to favour a balanced development of the new vegetation. Otherwise we can, if we want to, use a slow release fertilizer, to add to the soil, every 3-4 months.

Generalities Calathea ornata
The Calathea ornata develops like a perennial herb. This plant in the winter assumes a greenpurple colouring; it is large in size and can reach 1,5 m high. It keeps its leaves in the winter. The ramifications of these plants tend to develop downwards.

Watering Calathea ornataTenere asciutto
To avoid that a scarce drainage could favour the development of fungal diseases, let's remember to avoid leaving water in the saucer. We suggest watering these plants only from time to time, but we must remember to wet the soil deeply using 2-3 glasses of water every 1-2 weeks .

Treatments Calathea ornata
The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.

Soil Calathea ornata
These apartment plants favour very well drained soils.
