Hi Ken I agree some cultural info would be a great idea. I grow mine in a leaner mix as time passes. Water once per week or when the pot feels light. I use either chicken grit, pumice or perlite to lighten up the soil. I have switched to a different fertilizer regime. Two years ago I had some trouble with my Arums failing with yellowing of the leaves mid way through the growing season. One of the Formumist recommended a non ammonium fertilizer. I picked up one high in Nitrate nitrogen. So far last year it was improved and I've repotted in fresh soil so I'm hopeful that this year will be even better. I have also tried a Amino Acid fertilizer for my outdoor potted plants and had good results.

I have a number species and wondered if I could grow them better and reduce losses. When looking at the PBS site and other growers sites I found a lack of specific cultural information. Such as the potting mix, fertilizer type, frequency and when to use. Pot type could be a function of where you live and environmental conditions ie humidity . Also could the growing culture be the same for Massonia’s cousins in the Hyacinthaceae family Daubenya, Polyxena and Lachenalia? My mix is my cacti/succulent mix. 50% grit (pumice, turface, granite Diatomite) and 50% ProMix (HPCC with mycorrhizae peat/coir based). I am using mostly plastic pots. I fertilize monthly using a 20:10:20 peat-lite with minors formula slightly diluted. Once my winter growing plants break dormancy I place them outside and bring them in the greenhouse before a hard frost. All winter growers not just Massonia. They get a good 6 weeks of outdoor life with cool nights and warm days in full sun. They get fertilized at least once and watered a couple times. Our late summer and early fall there is plenty of rain. My losses aren’t immediately noticeable. They appear to go dormant healthy but I sometimes find a sinkhole in my pot in the summer as the bulb rotted. Did I overwater and especially near their summer dormancy? Is the mix not gritty enough? Should I move away from 50/50 and go to 75/25 or 90/10? Am I over fertilizing? Maybe just once or twice in the beginning of the growing season.
