Flowers are usually 5-10 cm in diameter, but their size is variable, because the larger number of flowers reduces their size.

The lower half of the inner whorl and the trumpet-shaped petals have purple spots.
PHALAENOPSIS STUARTIANA ORCHID CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Phalaenopsis stuartiana needs a light level of 10000-12000 lux. The bright, direct sun is destructive for the beautiful spotted leaves of the orchid, they acquire a yellowish hue, and often burn heavily.
Temperature:
The average temperature of the summer day is 29-30 ° C, the night 21-23 ° C, and the daily difference is 8 ° C. The average temperature of the winter day is 27-29 ° C, night 21-22 ° C, which gives a slightly smaller daily difference of 6-8 ° C.
Humidity:
Phalaenopsis stuartiana needs an average humidity of 80-90% throughout the year. In conditions of high humidity, it is necessary to regularly ventilate the room where the plants are kept, since wet, stale air is an ideal medium for the mass reproduction of various fungal and bacterial diseases.
Substrate, growing media and repotting:
Stuart's Phalaenopsis can mounted or grow in pot with bark granulation 12-16 mm with moisture retention additives or sphagnum with perlite or charcoal added for better drainage as substrate. Repotting is better done after flowering, when new roots are actively growing, but take care not to damage the roots too much.
Watering:
The frequency and abundance of watering the orchids of this species directly depends on the intensity of light and the overall temperature of the content, the higher they are, the more often and abundant it is necessary to water. It is recommended to use warm water for watering. Schedule of precipitation is wet / very wet.
Fertilizer:
It is recommended that 1/4-1/2 doses of fertilizer for orchids applied every week or every 2 weeks in the growing season. The best fertilizer is fertilizer containing nitrogen, phosphorus and kali in equal parts, for example, NPK = 3-3-3 or 8-8-8. If you do not have such fertilizer, then at the beginning of the growing season, feed the orchid with a fertilizer with a high nitrogen content, and after 50-60 days - with a fertilizer with a higher content of phosphorus.
Rest period:
These plants can grow and bloom in cultivation even at winter temperatures of 16-18 ° C. Plants should be constantly moist, the level of light is slightly lower, and water should not increased.
Do these need low temperatures in fall to spike like phal hybrids?
ReplyDeleteNo, they don't. You can keep the same temperature all year round! But the low night temperature is somewhat important!
