    Default laelia jongheana questions

    Hi All! Anyone grow laelia jongheana? I think it is considered as sophronitis now. I just received a very young plant and can find nothing but general guidelines for culture of the Brazilian laelias. Anyone have any input at all? Thanks in advance!

    I also have a couple of young plants in 6 and 7 cm pots that will bloom in 2 or 3 years. Mine are potted in a mix of bark, sponge and charcoal and perlite (from the nursery, not repotted them yet). They are growing fine with my other catts in bright diffused light and twice a week watering and alternate day misting. I am fertilizing with osmocote time release fertilizer at the moment, will start foliar feeding soon. I see a lot of root growth and a couple of new growths now.

    Thanks for the reply Amey! Mine is in the same size pot and potted in the same medium. It is just maturing its fifth growth and I can see two growths about to start. I was thinking of moving it to a clay pot with a mix of bark, charcoal, and small hydroton. What sort of temps are yours getting? And which osmocote do you use? I have the osmocote for potted plants. It is the high nitrogen formula.

    Jason your plants are much bigger than mine then. Mine have just one or two true miniature pesudobulb like things and one or two new growths on each plant. They are in my university greenhouse which has just a min temperature setting, so the temperatures never fall below 18 oC but on warm sunny days they get to even 40 oC. Weather in Bremen is so unpredictable at the moment that we have daily swings. The greenhouse also has an automated misting system which keeps the RH at 85-90% (on Sunny days it is a Sauna LOL). I really don't know what osmocote type it is, what I am sure is that it is a balanced formula.

    Grow the same way as for Laelia praestan, dayanum, pumila. Mine is about 4" tall (w one inch bulb and 3"+ leaf) and prob have another season before it bloom. Intermediate condition, bright light, dry between watering and slight dry winter rest. Depending on the clone jongheana can be as small as its cousin. but its typically slightly larger.
    This group is best grown mounted or in clay pot. Seedling might do well in pot, but once the plant is at least 4" tall they need faster drying medium. My L. praestan is mounted on a cork and blooms twice a year for me (praestan/dayanum are from lower elevation so they tend to have two growth cycle in a year in cultivation). L. jongheana from higher elevation and it normally only have one growth cycle so u can only expect to bloom once a year.

    Summer Night: 16-18'C
    Winter Night: 13-14'C
