Life form Shrub, tree
Family Pandanaceae

Ease of cultivation Easy
The size Up to 1.5 m or more in height, requires a large space.
Growth rate Young plants form only 2-3 leaves per year. Growth of adult pandanus is more intense.
Lifespan A perennial, extremely long-lived plant
Temperature It prefers the same desirable high temperature in winter and summer, best of all 75,2-82,4 ° F. In winter, the minimum temperature that a plant can withstand +64,4 ° F, otherwise the pandanus will quickly fall ill.
Humidity Requires a humidity of at least 60%. Spray 2 times a day, in winter you can not put the plant next to the radiators. You should use all ways to improve  humidity.
Lighting Plants with bright leaves prefer bright diffuse light lasting up to 8-10 hours, preferably the east or west window. Plants with green leaves can withstand shading.
The soil For a mixture of own preparation, take: 1 part of the turf ground, 1 part of the leaf land, 1 part peat, 1 part coarse-grained sand. Drainage is required.
Watering The top layer of soil between waterings in the summer should slightly dry up. Water approximately every 6-10 days. In winter, a less frequent watering is required. However, the soil should not completely dry out either. Pandanus, as a whole, is not afraid of stagnation of moisture, however, it is not necessary to specially waterlog the plant.
Fertilizer It is better to supplement the pandanus 3-4 times in the spring, but it is possible to feed the fertilizer regularly from May to October 1 time in 2 weeks. It responds well to organic top dressing.
Reproduction Upper or stalk cuttings with deciduous nodes 15-20 cm long. Root in a mixture of peat and sand, covered with polyethylene at a temperature of 78,8-82,4 ° F.Easily rooted young root shoots, separated from the mother plant. They can be cut off from the mother plant, cut with rootstock and rooted in a mixture of peat and sand at 77-82,4 ° F under polyethylene. Usually rooting lasts 3-5 weeks. Seed multiplication is possible in February-March at the same temperature (planted in sand or peat). Fresh seeds germinate in 2-3 weeks, the older seeds after 1-1.5 months. When the roots reach a length of 5 cm, seedlings are planted in 7-cm pots.
Bloom Male flowers form spikelet, female – a kind of cone. In the room, it does not bloom.
Transfer Young plants are transplanted annually. Adults – once in 2-3 years in March – April, when the roots fill the entire pot. Old plants can be transplanted even less often. When transplanting is not necessary to bury the plant too, because its air roots must at least partially be above the ground. In this case, the pandanus will grow faster.
Features of care Dry ends of pandanus leaves should be cut to a healthy tissue. It is advisable to regularly wipe the leaves. Be careful not to cut yourself against their sharp edges. You can not cut the air roots of the pandanus.
Difficulties It is infested with pests quite rarely. If the old leaves turn yellow and fall off – this is an esthetic process. Leaves bend in the middle in low light. The tips of the leaves turn yellow when the humidity of the air is too low. If the variegated forms are green, this is due to a lack of light or an excess of nitrogen in the soil.
