Cyclamen Potting Medium
Thu, 25 Jul 2013 14:16:29 PDT

For years I've used a Eugene company's "potting mix" which consists of compost, fine bark, sand and pumice with the merest touch of starter fertilizer.  The last two years or so I have added additional pumice, so that the pumice makes up 1/4 to 1/3 of the mix, then add a tablespoon of bonemeal, stirred in.  I also make sure I don't use any larger pot size than absolutely necessary. 
The other consideration I give is to where in my shade house or canyard I place the cyclamen.  Purpurascens, parvifolium and repandum go to the shadier end, as do balearicum, cyprium and libanoticum.  Graecum goes out in full sun, even in pots, and persicum and africanum are on the sunniest end of the shade house, where at times in the summer they receive brief full sun, since the end of the house is open in the summer and has no end shade cloth.
Just keep in mind that I'm on the southwest coast of Oregon a mile and a half in from the beach, with summer fogs and lots of wind.  Although this summer, we have been decidedly warmer on a day-to-day basis.  Watering has to be watched carefully with this free-draining mix and I will often "swipe" the containers when dormant almost daily.  In other words, they receive a bit of moisture but definitely not a soaking.
