These plants don't like the cold weather during this time of year. If the minimum night-time temperatures are very harsh it is best to cover the the Roscoea humeana with non-woven fabric. If you desire cleaning the ground from the bulbous plants after flowering, wait for the leaves to dry; later it’s possible to take the bulbs out of the ground and place them somewhere dark, cool and dry, until the best season to plant them again.Let's grow the the Roscoea humeana in a luminous place, with direct sunlight.
Care Roscoea humeana
These plants are bulbeous. This plant in the summer assumes a purple colouring; it is small in size and can reach 25 cm high. It doesn't keep its leaves in the winter. The Roscoea humeana has a panel-like development, therefore it tends to widen very much.
Feed Roscoea humeana
Let’s use a slow release fertilizer, or manure, when planting, mixing the product to the ground; during the spring let’s mix, every 15-20 days, a specific fertilizer for bulbous plants to our irrigation water, starting from the moment in which the first flowers are withering.
Irrigation Roscoea humeana
Water when the ground is dry; in case of prolonged droughts water very often, otherwise every 1-2 weeks can be enough using 1-2 glasses of water ; avoid water stagnations and excessive watering. We suggest not to exceed with the waterings: if the soil remains damp too long, it can favour the development of rotten in the bulbs.
Adversity Roscoea humeana
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.
Substrate Roscoea humeana
Cultivate in a quite humid, not excessively drained, soil.
