Brief Grow Blog and Pictures


This hybrid was in my collection in the early 1990's. I had one plant with icy green flowers and the other with pure white blooms. I'm not sure what happened to those plants, but after all these years I haven't forgotten about them. When both parents were in flower, I had to re-make this cross.   Clowesia warczewitzii has a small, light green flower with darker green stripes. Plants bloom in early winter, and the flowers have a pleasant lemony scent. Catasetum Orchidglade (pileatum x expansum) has a large flower with a huge lip in light yellow with scattered red spots. Expect full-shaped flowers in light green to white, and a few may be spotted as well. Clowesetums have many good traits:  long flower life, multiple spiking habit, good form, and pleasant fragrance. This grex should be excellent, and there's a distinct possibility that some plants will have pure white flowers. ( - Fred Clarke, Sunset Valley Orchids)





February 2020

Boxing Day - Catasetinae style.


Two bulbs and 2020's new growth starting to develop. When it comes time to re-pot this Catasetum I will position the bulbs so they "ride" just below or even with the surface of moss about 2 inches deep on top of clay pellets as I grow in a semi-hydroponic environment.


The picture to the left is straight out of the box. The picture below and to the left is after a little cleaning of the back bulbs.  The picture below and to the right focuses on this year's new growth starting to develop.  It makes an orchid grower happy to see new growth poking out and start the new year.

New growth is possibly a spike.


I been watching this closely and after doing some further research on Clowesetums I am reasonably sure this is a spike and not a new growth.  It is a lighter green then new growths and is growing horizontal from the base of the bulb.  New growths tend to quickly bend upwards and the tip displays small leaves starting to spread as they grow.  If it is a new growth I be just as happy but I seen many images of this Clowesetum spike and then develop new growth perhaps spiking again.


I have no plans to water this and will hold off watering until near the end of May so any new roots from new growths can stretch as far as possible to the bottom of the pot before coming in contact with water.  Once this contact is made, the root will actually stop growing.  Long healthy roots are healthy happy roots and thus the new growth be vibrant and blooms reach full potential.  I will continue to keep a close eye on the bulb for shrivelling.  The bulb is large and firm and should contain everything needed for this spike to continue growing and feature about 5 to 7 blooms perhaps in early April.


If the bulb starts to shrivel prior to May I will water lightly.


The image top-left is my potting strategy.  About 2/3rds clay pellet and about an inch of moss, tightly packed around the old root ball.  I made sure that the base of this orchid is just above the lip of the pot.  Spikes will grow horizontal and they should clear the lip and edge of the pot before gravity forces them to drape down the side of the pot.  A mounding of moss similar to potting the Neofinetia slightly lifts this Clowesetum.  I centered this orchid in the current pot as I have no plans to un-pot my Catasetinaes next dormant period and will just leave them in the pot for perhaps 1 or 2 growing seasons.


The bottom left image is a closer view of the spike. Looking forward to this bloom and it's fragrance. 


Next update be near the end of March.




23 March 2020

Leaving these orchids unattended during their dormancy period seems to in no way harm them or impede mother nature, they do what they do.


Clowesias and Clowesetums are probably the first to bloom in my collection while all the others are supporting new growth.


I left for a family vacation / retreat knowing this was "in spike" and counted 7 buds.  Upon my return I noticed it is supporting 11 buds and probably bloom mid April if not sooner.


This orchid has not had a sip of water since I received it and gae it a good rinsing and hen dry thouroghly outside the old pot before potting it up to my standard pot.  Trust me, the desire and compulsion to water is not easy to fight - but the back bulb in nature supplies everything the developing spike requires.  Resist watering I will do.


To support and prevent this pot from tipping, and protect the spike as it grows below the actual pot, I placed the original pot in a cut 2-liter soda bottle weighted with some "black sand" from Hawaii.  This provides some stability, but if you can hang these, that might be a better method.  The important thing is to protect the spike and its buds.


This particular spike might grow a little bit longer based on the distance of space between the buds in back and the newer buds in the front.


I will keep a vigilant eye on the condition of the back bulb with regards to shrivelling.


I was away the first 18 days of March and in my absence, this orchid only got a little bit of light so I am curious how the blooms will look, hoping for the male version.  Not sure how exposure to light determine the sex of the Clowesetum.  The early part of March as the spike and buds were developing, it did not get much direct light.


Now it gets more light but since it is in spike, I try and preent birght, direct exposure to light.


The first week of April, I will closely examine the bulb for shrivelling and if it is noticeable, I will compare earlier images of the bulb to current images of the bulb.
