Problem with sphagnum in the highland greenhouse


Recommended Posts

Hello,

I'm posting here because I have a big problem.

A few months ago, the moss that was on my highland nep pots in the greenhouse was beautiful, very green, robust etc ...

Like here:

Until then I used occasionally fertilizer for orchids I vaporisais on the moss, and plants with reverse osmosis water.

But since I stopped osmosis water, and I came back to the tap water, the moss began a complete change of mind ...

It loses all its force, becomes soft and full of algae dark is cleared very quickly, in short, not really beautiful.

More like a moldy carpet than anything else ....

What to do?

Repot all my nep with a new substrate (60/40 sphagnum / perlite)?

Give me a reverse osmosis water?

Remove the moss layer "dead" and put something else in place of it?

Personally never been a fan of spaghnum moss in any form, wet, stodgy horrible stuff thats been responsible for more roots rotting than anything else. Much prefer lots of perlite and a little peat, if you have a humid enough atmosphere you can grow live spagh on top if you want, or coir chunks, or coco peat / perlite etc etc. when i think of spaghnum i just think acid, anearobic, raised bogs, and neps arent bog plants...

Lawn/hanging basket moss works great though.

Neps may well like some fertilisation that the sphag cant tolerate.
