grow moss on breezeblocks

[jayneangel]

how do i go about growing moss on a breezeblock wall? its only 2 blocks high but 70 foot in length. thanks

I've heard that you can smear natural yogurt onto brickwork to promote the growth of lichens & mosses. I think you'll need a fair bit for 70ft of wall!

I am sure I read somewhere about painting a surface with milk to encourage lichens etc to grow on it ... might be worth trying a little match somewhere dry

I recall that applying natural yoghurt to stone encourages the growth of moss.

I am just intrigued as to why you'd want to do this ...

OK, assuming you really do want to make this block wall into a *natural* looking structure (?????), just mix a large (4 pint) bottle of full fat milk with some soil from a garden or compost heap (not potting compost, that will be quite sterile), add another 4 pints of water, stir well and pour the muddy mix over the blocks. Wait for a few months and hopefully the moss will develop. If the wall is in full sun, you'd do well to cover it with black plastic sheeting during the hottest part of the day to keep it moist.

I agree with the guys who said milk or yoghurt
