Catasetum Dapper Dots



Catasetum sanguineum


Catasetum pileatum var. aureum





Catasetum Dapper Dots is an orchid hybrid originated by Mrs R.Levy in 1987. It is a cross of Ctsm. sanguineum x Ctsm. pileatum. It is considered a "primary hybrid" because it is a cross between two species.

I was gifted a growth of 4 bulbs and the latest had a swelling indicating a new growth in its fuure.  I divided this into two pieces both having 2 bubls each identified as (A) and (B).  (B) is for trade / sale.   Below is my care for these items mostly from memory.   


November 2018

WHen I received this item I figured it was already well on its way to enjoying it's well deserved dormancy rest.  After dividing and giving a thorough cleaning, triming of roots and allow a few days to dry off good, I positioned them into my home-made terrariums (see terrarium discussion here).  During the unusual sunny and tepid late fall here they were situated in a place in the mini-greenhouses where they be exposed to bright, ambient light, but not necessarily direct sun light.  The humidity, bright light  and warm temperatures must have cut into the dormancy period as (A) had new growth slowly start forming whiloe (B) showed signs of swelling.  Mid-Decembver into January, the new growth was already taking off.  I talked with a few others in the area that have Catasetums and they to reported new growth.  Fred Clarke repeated their replies to my questions, but added "longer growing season this year"     



January 2019

Division (A) in the terrarium kept on developing 2 new growths, one on each bulb.  Eventually the leaflets started to form and spread, the roots, barely visible, started developing.  The new growths started to resemble the parent bulbs except for in size.

Division (B) started to swell and follow it's twin.  I am guessing the oldest bulb which has an eye yet to swell be the runt or the last to develop if at all.



February 2019

Not exactly sure when, but perhaps in a rush before its time, I moved division (A) from its terrarium to my semi-hydroponic pot in moss.  (My semi-hydroponic pot is discussed in detail here)  The hardest part of Catasetinae culutre is the rush and not wait until the new growth is ready to be transitioned in a new pot thatwill be its home for the season.  Oh well, what is done is done.  This early potting up does not seem to have harmed the new growth as they continued to expand.

I made sure to squeeze the moss of excess water as much as possible.  I did water this division and then tilted the pot so the excess water would drain as much as possible.  Otherwise I did not have to water the rest of February.  I kept an eye on the pot because it seemed much more moist than I expected and I was concerned that too much water start causing rot.

One thing I did notice was that the orchid started to settle into the moss dropping lower than I desired.  How to fix this was something I contemplated for some time.

Division (B) remained in it's terrarium.

On sunny days both were positioned in my mini-greenhouse enjoying the light of the sun and warmth captured by the greenhouse.



3 March 2019

I worked on division (A) slowly pulling some of the moss out of my s/h pot until I could easily lift out the orchid.  The roots are at the desired length (about 2 - 3 inches in length.  I added more moss to the pot and using skewers to keep the bulb s from sinking arranged the orchid to be almost floating near the surface and then slowly back-filled with moss making sur the orchid not sink any lower.

Shame on me, but I decided to remove diivision (B) from its terarrium into its new pot.  Learning my error of it sinking, I have it supported by a collection of skewers.  The leaflets are visible on the new growth but have not started to spread.  Again, I rushed this and hopefully it not cause any problems down the road.

In the pots, I arranged the old bulbs at an angle so that the new growth is pointing straight up.  Division (a) with it's leaves spreading is positioned in a prime spot so it gets plenty of slightly shaded sunlight.  Division (B) leaves have not started to spread so it will be positioned in a more protected area. 




April 2019  (Date of image is 20190401) Re-potted into it's grow season pot.  Removed the styrofoam peanuts from the old root-ball but this year I left a majority of the previous roots undisturbed.  Arranged the old root mass to be nested in fresh damp moss using the old surface of moss as a guide to determine the position so that this year's new growth is centered as much as possible and level if not just above the level of new moss - some sinking / settling might occur and to prevent this the moss below the old root-mass is compressed.  One thing I wanted to avoid is sinking the bulb too low in the moss.

Both these Catasetums are the leaders for this year's growth and about ready for full watering with diluted fertilizer.  I have already added some time-release pellets to the moss.


I carefully add a few drops of water from a turkey baster on the outer edge of the pot to keep the moss damp.  By the end of April I suspect the spikes be more obvious and the new growth be ready for watering with a diluted fertilizer.  Currently, this orchid is in the second row from the front getting ambient light until the afternoon, bright light in the afternoon with some more direct but diffused light mid-afternoon to sunset.


(Mental note:  remaining pictures for this grow blog will be situated with the growth in the same position so as to avoid confusion and attempt to be consistent.)

I need to find a way to "train' these so they grow up and not to the side.  If they grow vertical, they take less room.  I also have some concern  that the bulbs are not swelling in order to support next year's new growth.  Only conclusion I have or the swelling is to increase frequency of watering for the rest of June, into July and through August when hopefully I will see a spike appear.


In the meantime, it appears they are getting plenty of light.


So far, so good.....




July 2019

Care:  Moss in a semi-hydroponic, almost clear plastic food container.  Exposed to bright light, but not direct "cattleya" light.  All greenhouse items are placed in a water tray for extra humidity due to evaporation.  Exposure (time of) direct light is on the increase as the solstice has passed and the sun slowly gets lower in the horizon.  This also means heat is on the increase in the mini-greenhouse as well.


Catasetums are water hogs, so drowning from over-watering is difficult at best.  Starting back in late April, when the new growth was about 2 inches tall, I started watering to moisten the moss with a few squirts from a turkey baster near but not immediately surrounding the new growth.  Once the new growth reached 4 inches, I could only guess the roots were established (2-3 inches in length) and started absorbing water, so I would increase watering with a balanced but very diluted fertilizer.  In may, I slightly increased the fertilizer and watering as needed.  Because their is a reservoir of water at the bottom of the pot, I did not fertilize except for once a week, the rest of the waterings during that week would dilute the reservoir. 


With the advent of July, watering with very diluted fertilizer is just about every other day and during any heatwave more as needed.
