Problem with sphagnum in the highland greenhouse

[gabgabinou 86]

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?

Hi,

I would do the following things:

1.No

2.Yes ,definitely

3. Yes,I would remove it and let it grow back from the underlying moss.

Okay, so,

I use Osmosis water, and, I remove the moss dead, but I do not put anything in its place?

I leave it as is? I do not put moss living in the place of the dead?

If you have fresh Sphagnum you can put it on top if you want.

and I would water well with the reverse osmosis water because if the moss doesn't like the water, the plants may not like it either.

What do you think of the pozzolan to the surface of each pot instead of peat moss?

[Simon797 1]

It wouldn't be as nice looking .

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.

So you think I should redo the substrate of all my nepenthes?

You should use what works for, everybodies conditions are different, a bit of experimentation might be worthwhile though.
