Yes other kinds of moss will probably kill youre Nep seedlings, unfortunetaly its hard to come by pure sphagnum moss. I am currently trying some LFS i found at lowes (a rare occasion) and trying to propogate it, it will take time but it should propogate sooner or later. Hope fully it takes. Cheers

fmogul; Moss on rocks, bricks and stones. On some level of artistic perception the thought of a plant growing on a rock et al seems mysterious and breathtaking. Yes moss can grow on these three surfaces. And I suspect your neighbor is growing moss and not mold. How to encourage? Use a pump up sprayer, $9 at WalMart, and spray/mist every other day in the fall in dry weather with rainwater or distilled. You can find acidic fertilizer at the same store for 40% off now. This is liquid soluble fertilizer. Acidic fertilizers are recommended for azaleas, rhododendrons and other acid loving plants. Usually the recommended dose is one tablespoon per gallon for regular plants not moss. For moss on rocks use 1/4 teaspoon per gallon in your sprayer every third week. George Schenk in his book Moss Gardening does not recommend fertilizing moss on rocks because the moss will lose it's grip on the surface and fall off. But I think this very weak solution every third week will be ok. Hanging moss or confining it to one area? Well chicken wire won't work because the zinc galvanized coating will kill the moss, guaranteed. Moss also needs to be in close contact with a surface that does not have air pockets under it. So for eaxample moss does not cover rock or wood mulch unless the environment is one of perpetually high humidity and for the same reason moss doesn't won't grow has a hanging object if it gets too little humidity. Is the brick a smooth surface or coarse? If smooth you could try using a mortar mix with one third by volume wet peat moss to cover a wall area you really want to encourage. after a week use a one quarter vinegar solution and water to wash down the fressh morta and reomve some of the alkali residue. Then blend some of the moss and some beer or buttermilk or yogurt all of which will help the moss adhere to the mortar until the moss can grow. In any case watering now in the fall will greatly encourage moss because the Fall and Spring are the moss growing seasons. When all else turns brown and withers moss perks up and glistens. Rick

Thanks, Bamaud and Terrestrial_man. I am sorry I thought the forum would mail me on post activity but mabe I have to set up how to follow the thread. Thank you for your help. Yes, it is definitely a liverwort - a thalloid one. About being a Conocephalum, well, mabe. Meanwhile, I uploaded some macros: I don't know why but it looks like they get some stripes - so I uploaded also a zip with all the 3 of them: http://www.agilitas.pt/moss/RB0_0319.zip Thanks, Once again for your help.

In the cavern, I think you will struggle to grow much of interest in the summer, maybe a few tough ground covers like Vinca minor or Ajuga. Think about woodland plants like bluebells (I was thinking of the English ones, but pick your favourite), snowdrops, hardy cyclamen, lily of the valley, possibly colchicum. You might even get Brunnera to live under there, they prefer moisture but will survive dry summers. Your moss sounds perfect for the traffic area. The less cultivation you can do the better, compact trampled soil is inhospitable to most plants but moss likes it. Maybe it needs more trampling to suppress the grass.
