During warm season temperature is maintained at the level of +20-24 °C, in the winter it reduces to +18-20 °C though the plant is capable to transfer cold snap to +12-16 °C. Adult copies are less susceptible to cold, than young people. Indoors, where there is howea, there has to be continuous inflow of fresh air, at the same time it is necessary to avoid drafts.
The howea is watered it is abundant, using soft otstoyanny water. It is only necessary to start the following watering when the top soil dries up.

Substrate is prepared from the cespitose and sheet earth, humus and sand. Recommend to increase humus share with age. Delete old layer of drainage and top layer of the earth, trying not to damage roots. The size of pot is increased in process of growth of plant. The howea is made multiple copies seeds, however on receiving average copy 5-7 years will be required, very slow growth is characteristic of this plant. Crops is carried out at the end of winter, as substrate use peat. For successful prorashchivaniye of seeds it is necessary to maintain temperature about +27 °C. When shoots develop, them it is necessary to dive on one in pots of 8 cm in size. Then seedlings contain at temperature of +18-25 °C.
