A European cyclamen expert -- whose seminar I attended -- said the best thing to use as mulch for the cyclamen pots or garden area was #10 turkey grit, at a depth of about 2 inches. Cheap, and easy to get in bulk at the local feed store. Here in the Northwest our soil is always a bit acid, and the grit balances it beautifully while giving the plants the minerals their Mediterranean DNA demands in a bio-available form. My C. coum thrived under an Aesculus when I did this. Each autumn, I'd throw down a bit of straw which was insurance just in case we got a freeze. I'd remove it early spring.

The bench is 7 inches, level of sand somewhat less. Up to 6 inch diameter pots can be standard proportion - height and width are the same (if 6 inches wide then 6 inches tall.) Most Cyclamen hederifolium are in 4 inch pots, a couple are in 6 inch. My two gigantic cyclamen - Cyclamen persicum that I've had since 1973 and the C. rohlfsianum cannot have standard pots because the sand bench is not deep enough. The latter was in what's called an azalea pot, 2/3 deep as wide, which was 8+ inches wide. It's current (plastic) pot is roughly 11+ inches wide, 6+ inches deep. The C. persicum is in a terra cotta bowl 14+ inches wide. If you want I'll measure pot height when I hoick it out of the sand to top-dress or repot later in August or early September. I periodically make a shout-out to my garden club, requesting any unused / no longer wanted terra cotta pots. That's my source for 4 and 6 inch pots. Anything much larger is difficult to acquire. "Modern" pots, when found at a shop, are - call it flimsy, with thinner walls. Or they are extremely expensive, fancy,made-in-Italy Seibert and Rice terra rossa pots.
