Mine has only just started its growth, it's only a couple inches yet. When it's time, I do top dress with Dyna-Gro, so hoping my results are just as spectacular.

Help my first Catasetum that I just got has a couple of the older bulbs getting mushy. It is packed in Sphag all the way through. What do I do to make sure the rest doesn't die?What am I doing wrong? Please help?

you might be OK if the new growth is firm and green ? is it too late to repot and cut or break away the mushy growths ? you could lift the entire plant, cut the mushy part away with attached moss and place into a slightly bigger pot with a bark mix ? it sounds as if you have overwatered.......best to post photos on another/new thread.

The mushy part could also just be the plant absorbing its old bulbs, so you don't necessarily want to cut it off. A picture would help. Is the "mushy" bulb a light brown to straw color? Or is it black?

I don't know what is going on with my catasetinae. They started growing so I potted them up, but now their growth has just kind of stagnated. It's been more than a month or water/fertilizer and nada. The others that are dormant are still dormant as well. Maybe I should have tried this horse manure thing xD

These guys often abort growths if disturbed at the wrong time. They'll just start growing new ones soon, but this is one reason why I don't like to unpot my Catasetinae every year.

Fresh horse manure might be worth a try, but I'd prefer old cow manure - seriously.
I just finished repotting of about 400 Catasetinae, what I do every other year. This time I used a mix with wood shavings, as sold in pet stores as absorptive litter for rodents. And I added a slow release fertilizer, those globules that are added to jardinieres.

As requested previously, I started a new thread with pictures of my plant that I am not sure if it is in trouble or not but would rather not let it die. Advise on corrective action or simply how to correct my actions would be appreciated.

one of the bulbs is at least 10 inches long, but more of interest is that another new growth is emerging. Its never happened to me before on these large catasetum types ! Plus there are 3 more months, at least, of growing.
The tenth leaf appears to be the final leaf - its very small - so maybe I will get a spike in the next month or so as the bulb matures.

Please keep us updated about your success. I am curious how bulbs will look at the end of the growing season.
