Costus speciosus

Light Costus speciosus
We suggest locating the vases in a pretty bright place, although avoiding direct sunlight, which could damage the foliage. These plants are rustic in the areas with a Mediterranean climate, therefore they can be grown outside.These plants are frightened by direct solar rays, which could ruin their leaves; we suggest to place them in a shady place.

Water Costus speciosus
It is advisable to water the plants avoiding to leave water in the saucer, because stagnant water often develops fungal diseases. Let's water abundantly, moistening the soil deeply with 2-3 glasses of water , but let's act only when the substratum is dry, leaving it dry even for 1-2 weeks before watering it.

Fertilize Costus speciosus
During the spring let’s regularly use a fertilizer rich with nitrogen and potassium to favour the development of the new vegetation; fertilization is done by adding fertilizer to the irrigating water, every 15-20 days.

Pests Costus speciosus
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there aren’t flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.

Mold Costus speciosus
These plants favour soft and very well drained soils. We suggest, every 2-3 years to repot the plants, changing the soil.
