I have a victorian 'Grotto' ( a style of conservatory with walls made to
look like the inside of a cave but with multitudinous pockets of soil in the
rocks for planting puroses)

There was some difficulty replacing the glass roof with the result that it
was open to the elemnts for some considerable time and the rock- which I
suspect to be Tuffa- has become much covered with moss and lichens.

I have removed most of the plants and the soil but would like to know what
would be best way to kill the green growths on the rocks to restore their
colour back to the origionalwhite/yellow and allow replanting (with fresh
soil in the pockets)..
I have been told that some chemicals may prohibit replanting for a very long
time.

Any suggestions greatfully received

Regards

I thought they were sopposed to have moss and lichen on them? However if
you really want to remove it then a pressure washer will do the job in no
time (even if a little messy!)

I wish I knew the secret of growing green covering on rocks. Moss
would be wonderful. It looks much better than just rock!

To get rid of green algae we have used Bayer Dimanin Green.
It was the only product tested by the Dutch Consumer Association that worked. It
worked for us too.

Yes but Steve *wants* stuff to grow on rocks - hence the yoghurt etc.
suggestion.

It did (presumably) look natural before the green growths occurred since
this was how it looked was garnered, put in place, and remained ffor some
100+ years untill the roof was left open .

I just want to return it to its natural looking state
