Here are Fred Clarke's notes that were included in the "Catasetinae drop" email that RJ posted. Figured it should be a separate thread... covers some questions that get asked frequently. For the record, I have a bunch that are on their way to blooming. Some started to develop buds even before they were ready for watering. Eager little guys.
Plant culture
Your Catasetinae should be in growth by now, with many growers in southern parts of the country already seeing some plants bloom. Watering and fertilizing should be in full swing for most everybody. This is when your plants really put on their best growth. Fertilize with each watering using with ˝ tsp fertilizer per gallon of water through October.
Remember - no more re-potting at this time. However, it is ok to ‘slip-pot’ into the next larger pot size. Just wrap more moss around the existing and slip in to the next larger pot, being careful not to over pot or damage those important new roots.
This is when your Catasetinae can really take advantage of lots of light and air movement to help push and develop large new growths. Ideal temperatures in summer are 80-95 degree days and 60-75 degree nights, with humidity between 40% and 80%.
Keep an eye out for spider mites, which can get a foot-hold on your plants (and they have 8 feet!). Be diligent and check the undersides of the new leaves regularly. If mites are detected, spray immediately. They can quickly get out of control if early action is not taken!
