    Default How to best grow Paphiopedilum haynaldianum?

    I recently received a Paph. haynaldianum in the mail. the plant arrived healthy and is growing slowly but surely. It is probably a NBS plant as the longest mature leaf is 7 1/2 inches long. Any tips on growing this plant? How would the culture differ from, say, Paph. glaucophyllum (I got mine to produce a bud) ?

    I wouldn't be of much help but there are several who would be.

    A mature Paph haynaldianum will have leaves mostly in the 9-15" range, and usually needs multiple growths to flower, so your plant may have a bit to go. Typical recommendations for Paph haynaldianum and Paph glaucophyllum are essentially identical - light 1500-2500fc, daytime temps 70-85F and 10 degrees cooler at night, even moisture never soggy, very little seasonal difference but can be kept a bit dryer in winter, 1/4 strength (or less) fertilizer when in active growth.

    Some paph growers say from their experience that haynaldianum prefers a more open potting mix and prefers to dry out slightly in between waterings, compared to glaucophyllum which has thin leaves and likes constant moisture. Maybe less moss or more large spongerock/pumice in your mix, since I am not sure what you have them potted in and your growing conditions.

    That makes sense, as they are often lithophytic from what I have read.

    Plants growing as lithophytes can be misleading. At first look, one might consider them to require less water and rapid drying, but very often, you will find that they sink their roots into the humus-filled fissures in the rocks, where they remain cool and often constantly moist.

    I have never grown glaucophyllum, but haynaldianum has always done really well for me in Semi-hydro culture, which is airy, but constantly moist.

    So far, the plant is growing slowly but surely. It is also developing a second fan. If it takes awhile to bloom, it should be no worse than waiting for a Cattleya Hauserman's Firewings 'Pegasus' to bloom, which It did a number of years after I bought it in a 2.5" pot. Quite the thumb-twiddler!

    That slow feedback loop is one of the reasons I am not a huge Cattleya fan. Love the flowers but the slow........
