Antwort auf: Do cyps like Calcium? von Stephen Vella am 03 Oktober, 2009 um 14:50:15:
Hi Stephen,
I don't know that some Cyps would like calcium. I just read it every now and then, but the proof is missing!
In nature soils with calcium are often well aerated and have a crumbly structure. That is what Cyps like. I grow nearly all Cyp species in the same soil mix, give the same fertilizer (only in different concentrations) and they do well. (Sorry, no details because of my professional production of the Cyp hybrids.) Don't worry or care about the calcium, except if you used only pure rain water for watering. Normally tap water contains enough calcium.
I would not use blood and bone for potted Cyps. I would be afraid of the biological activity which might be too much for the Cyps. Stay with the mineralic fertilizers.
I hope this helps.
Happy growing
Michael
