roscoea

Roscoea humeana should be watered whenever the soil around its roots feels dry, usually about once a week. During the summer, it may need more frequent watering. When watering your Roscoea humeana, be sure to drench the soil and avoid soaking the foliage, as this can cause diseases. If the plant is in a pot, check the weight of the pot. If it is light, then it needs water. Over-watering should be avoided, as this can cause root rot.

Roscoea humeana is a shade-loving species of plant native to Northeastern India. To ensure optimal health and growth, the plant should receive roughly 4 hours of direct sunlight each day. While some variations of Roscoea humanea can tolerate a few more hours of sunlight, 4 is the ideal amount for this species. The root zone should be shaded during the hottest hours of the day (noon to 3pm). Too much sunlight during these peak hours will cause the leaves to yellow and curl. For best results, Roscoea humeana should be placed in the indirect sunlight of a west or east-facing windowsill.

Roscoea humeana, commonly known as the Himalayan Ginger, should be pruned after flowering in early spring. The goal with pruning Roscoea humeana is to cut off all dead or diseased branches and re-shape the plant; only very minimal pruning is required. Pruning Roscoea humeana too extensively can reduce the number of flowers produced the following year. When pruning, you should aim to only remove a couple of branches, no more than 1/3 of your total shrub, and always cut just above a bud. Avoid pruning Roscoea humeana in the fall; this species is not winter-hardy.
