Dendrobium sanguinolentum


Water: Mounted: every day to every other day; potted 1-2 x/wk; I've found that whenever I neglect watering for a few days, buds start to appear.
Humidity: 50-70% humidity
Fertilizer: 20-20-20
Temp: 75-85F
Light: 60% to 80% shade (2,000 to 3,500 FC); Leaves should be a light green, not yellowish (too much light) or dark green (too little light). They should be somewhat stiff, not long and floppy (more light needed). A reddish edge to the leaves indicates the light is on the upper boundary of a proper level of light.  Direct sunlight may cause the plant to burn and not enough light will slow growth and stop flowering.
Repotting: Frequent keiki's. Trialed a repot on 4/2014 in regular fir bark media. Appears happy at the moment. Also shared a specimen with the newlyweds Karl and Ainslie Knaur in 8/2013. 

This is another specimen obtained from the 2013 GNYOS Annual Orchid Auction. Also frequently blooming all year round. The bloom picture to the left was from July 15.  This was the most vigorous and plentiful multi-bloom event yet. The flowers last just a few days. It rebloomed again August 22. There were two buds. Sadly, if you neglect to water it immediately when the buds form, you can lose them. I lost one- resulting in one lone bloom.
