J.—EASILY GROWN FROM CUTTINGS

During midsummer, in a shaded frame, in moist sand, many rock plants may be increased rapidly from cuttings, like geranium slips on a small scale. Where seed or division are not possible, this is the commercial method of quick multiplication. One plant will soon make twenty small ones. The Mustard, Pink, Sedum, Mint, and Composite families are mostly examples of growth from cuttings.

K.—RAISED BY DIVISION

Many rock plants may be pulled apart in summer, and each piece, if carefully set out and watered, will soon be as large as the parent plant.

Even if seed or cuttings are possible methods, this gives the largest plants quickest and with less trouble for the beginner.
