Several years ago I read, if I mistake not, in a German magazine for Horticulture, that dried and pulverized moss from trees, and the large roots of trees exposed to the action of the atmosphere, were a very useful addition to almost all kinds of soil used for potting plants. When the potting season arrived I did not think of it, and it was not until last spring that I tried it as an experiment. The confidence I had in the advice was so much rewarded by surprising results, that from that time I have hardly ever potted a plant without the addition of some dried and pulverized moss.

As soon as the moss is gathered, I dry it in an oven till it is easily reduced to a coarse kind of powder by rubbing it with the hands. Then I rub it through a common coal-sieve. Of the coarse powder obtained by this process, I add more or less to the soil. As it makes the soil porous and light, fertilizing it in a high degree, it is impossible to determine the proportion in general; for this depends upon the nature of the soil, as well as on the plant to be potted. Frequently I take a good handful for a seven-inch pot. It never sours the soil; consequently there is no danger in taking too much.

All my plants, except the Cactae, are at present growing in soil mixed with moss, and I must confess that I never before saw them as vigorous and healthy.

Amaryllides, Lilia, Gloxiniae, Passiflorae, and a large number of other perennials, are thriving in soil so prepared, as well as annuals; i.e., Reseda odorata and Linum grandiflorum rubrum, of which I have some specimens grown in the form of little trees, covered with blossoms and buds. They bid fair to be in bloom during the whole winter.

Moss may be mixed at pleasure with heavy and light soils, improving them both. Any one that will try the addition of moss to the soil will very soon feel induced to adopt it as a general rule.

[And we have no doubt at all that they will thank you for calling their attention to it. The moss acts both mechanically and chemically, and we should judge it to be a good addition to any soil. Charcoal and moss make an excellent compost to strike cuttings in. - Ed].
