Having pretty much outgrown its little flask, the Disa bivalvata was opened on Sunday, had distilled water added up to the top of the label as per the attached instruction leaflet, and after three days like that, it was time to pot up.
I sterilised a smallish (9cm) pot and some spoons in some hot water with Jik (household bleach) and then thoroughly rinsed it. The potting mix was rehydrated with distilled water.
|You can see how ready it was to be potted!|
I gently removed it from the flask with a teaspoon; the distilled water soaking loosens the agar up quite nicely.
|Disa bivalvata unflasked, with some agar still adhering.|
|Cleaned plantlets. 3 were in the flask.|
I then mostly filled their pot with sphagnum-based potting mix, and gently packed a little ball of it around the roots and tubers before putting each plantlet into the pot and then putting more mix between the "root balls" to keep them in place.
|Plantlets now in pot.|
|Old and new home (taken with dead flash batteries, hence the blur...)|
|Added to the collection!|
I put them into the cut off bottom of a water bottle and topped it up with distilled water as you can see in the picture above. So there we go. Hopefully, the plantlets take to their new home and our version of green-ish fingers! I've just ordered the Grow Disas book from SANBI as my regular online book dealers don't seem to stock it.
The Captab works very well as it is somewhat systemic, otherwise the better known fungicide to use is Dithane, both can be used at the recommended dosage.This is mentioned in the Grow Disa book, but I will improve it on the instructions label,
We bought Dr. Louis Vogelpoel's Disa book at Exotic Plant Company, but it seems a little dated. Pretty much all the information in it is available almost verbatim online in these culture notes.
Disas.com has a very comprehensive guide to deflasking.
