I was wondering if there are ways to prevent or get rid of algae, on Cephalotus substrate. The algae probably do not harm the plants in any way, but it takes away the flair of Cephalotus. At least, that is my opinion. I don’t have algae on all my Cephalotus soil, but some do. What I can’t seem to understand is why some soils turns green and others stay the way they are long after you repot.
For example, I did some divisions a few weeks ago. Therefore I use transparent plastic bags around the plants, for high humidity, for it to root properly. It takes a few months before they are acclimatized. I use a very aerated soil with peat and perlite. This time I did not mix sand in my substrate, because they also say that sand makes soil alkali and thus makes algae grow more/better. But on top of these plant divisions all perlite grains are turning green from algae. Does high humidity affect this?
Are there ways to prevent this or make it go away, without harming your Cephalotus?
Should your soil mix be sterilized before use, for example steam sterilization or by putting it in the oven for a few hours? What is your experience?
As I mentioned before, the algae probably does not harm the plant, but it takes away the flair of Cephalotus this size. Maybe this is just a pre-stadium of moss
Pictures show, Ceph division in three week old soil, note the algae
