In the September number of the ' Gardener,' my attention was drawn to an article by J. S. on the propagation of Lobelias and Centaureas. I quite agree with J. S. so far as regards the propagation of Lobelias from cuttings being more convenient than raising the plants from seed. I have myself practised that system for several years now, and have found it not only more convenient, in relation to time and labour, but much more satisfactory in its results. The plants from cuttings have a decided advantage in the flower-garden, there being more perfect uniformity both in colour and habit, and not having the coarse growth of seedling plants, which gives better effect in the bloom of the cuttings. My plan is to strike a few cuttings in autumn, taken from, the best plants, and these cuttings constitute the stock plants. The system is to strike in saucers with sand and water, placed on bottom-heat: two or three days is sufficient to have them ready for potting off; but I prefer boxes, as they take less space and are more convenient for moving about. After potting off, they are placed in heat for a few days till growth has commenced, when they are gradually hardened off. In spring the plants are cut over, and the cuttings treated again in the same way.

Hundreds of thousands may be got up in two or three weeks in this manner, as scarcely a cutting fails to strike root.

In regard to propagating Centaureas by cuttings, the same method may be followed with perfect success; in fact, mostly all of our soft-wooded bedding-plants can be stiuck in sand and water. I have tried it successfully with some of our most delicate Geraniums, such as Mrs Pollock, etc. It only requires judgment in the amount of water to be kept in the saucers, as some plants will stand more than others. It is the simplest and most effectual means of propagating Fuchsias, Verbenas, Heliotropes, Iresines, and all plants of the soft-wooded kinds. Robt. Stevens.
