Matt, Thanks for the reminder--I really need to repot some of my cyclamen, too. I have more or less abandoned growing coum and hederifolium in the greenhouse, however. After an initial period of doubt and caution, I've found that they grow much better in the ground outdoors. They never seem to be all that happy where I plant them, but the ants seem to distribute the seeds to perfect locations. No worries about hardiness, either. We're pretty much in the same zone, and you should have the same experience. Yeah, you don't get to enjoy them in the greenhouse, but that's a small sacrifice to pay for seeing them look so much better in their element. Hint: find a north facing location. All of my purparescens and cilicium are outdoors, too, with similar results. That said, rohlfsianum are my favorite cyclamen, and I think I grow them reasonably well. My oldest plants are just over twenty years old, with tubers that weigh around five pounds without soil. In general, I don't repot until they break their pots, which seems to happen with alarming regularity. Do not overpot--an inch between the tuber and pot is more than enough! I would recommend a soil mix with more sand and grit than might be used for hederifolium and coum. I keep terrible records with regards to soil mixes, but if I was repotting rohlfsianum I'd use one part peat/coir mix (Metro 380 or equivalent) to one part perlite, one part grit/pumice, one part coarse sand. Please, please do not plant the tubers too shallow! Rohlfsianums root on the top surface of the tuber (as do hederifolium). It really pains me when I see photos of exposed tubers--this is not how they want to grow. Put at least an inch of soil on top, preferably two, followed by a top dressing of another inch of coarse gravel (1/4" to 3/8"). The other thing about rohlfsianum is that they have huge leaves (I've seen them 8" across) that transpire a LOT of moisture in our dry winters. They dry out quite rapidly, so for the larger ones I use big plastic pots placed in deep saucers. The best way to water is to fill the saucers to the brim in addition to giving to top watering. There is no such thing as overwatering rohlfsianums in the winter! Even a plunge bed may not be able to keep up. My second favorite greenhouse cyclamen was received as africanum, but is most probably x hildebrandii, a hybrid with hederifolium. To me it is far superior to either parent. It starts blooming in late August, and continues non stop through December. At peak, it has at least 200 flowers open at a time. The leaves and flowers go straight up from the tuber, and don't have that annoying habit of going out to the edge of the pot before deciding to emerge. This has a tuber that is pushing ten pounds. Potting is similar to rohlfsianum. Most of the tender cyclamen spend the summer under the bench in the greenhouse with no intentional watering, and go outdoors at the beginning of September, earlier if they show growth. Off to the potting bench now... --Roy NW of Boston Zone 6-ish, was 5, headed for 7 Cool greenhouse, 38F
