The Cineraria may be classed among the most useful flowering plants we possess, and can be raised in any quantities desired from seed. If wanted to bloom about the holidays, the seed should be sown about the first week in July. The seed should be sown in a shallow box or seed-pan, properly drained and filled with a compost of the following soils: Three parts good loam and two parts leaf mold, the latter of which these plants are more than ordinarily fond; mix with one-sixth sand, fill the pan to within an inch of the rim, pressing it moderately firm. Water the pan through a fine rose so as to settle the whole, and sow the seed, not too thickly, or your plants will be crowded and drawn, and liable to get the roots injured in potting off. Cover the seed thinly - say an eighth of an inch - and press firm, place the pan in a frame kept close and moist to insure germination. When the seedlings have shown themselves, keep them well up to the glass and shade from the direct rays of the sun. When large enough to handle prick out into a regular greenhouse box, such as is generally used for bedding stuff, making the soil a little coarser with less sand.
When they have grown to touch each other, they should be shifted into 4-inch pots, using the same compost as was recommended before, through each succeeding shift; there is nothing more suitable. They should be kept in the frame till such time as frost puts in an appearance, when they should be removed to the greenhouse without further delay. If the frames that they are kept in in the summer and fall months are on the shady side of a wall, so much the better, providing they do not get too much shaded; and if the frames are so situated that they get the direct rays of the sun in the middle of the day, they must be slightly shaded. Give plenty of air from the first appearance above ground, and never suffer them to get dry or pot-bound, for if once they get stunted they never make such firm, healthy plants again. Six-inch pots are large enough for most purposes, but I have grown them large enough to fill 10-inch pots, and nice specimens they were. If the plants are a clean, healthy stock, and attended to as they should, with a liberal supply of manure-water every week, they can be grown into very fine specimens.
The Cineraria is more than ordinarily subjected to the attacks of the green-fly, and if I may be allowed to coin the expression, it seems to be a chronic disease with them. To keep it from ever getting established upon them to any considerable extent, the following remedies have been found good: Fumigation with tobacco stems, which must be done lightly and often; a better way is to have a good sized pail of tobacco-water and dip them when they are found to be badly affected. I have found by experience that tobacco dust is a good preventative when put on in the following manner: Wet the plants enough to moisten all the foliage, then dust the plants all over, when it adheres finely. Be sure and get a good supply on the under side of the leaves and in the heart of the plant. This is better than half a dozen fumigations, and it seems to fertilize them at the same time. If treated as I have recommended, Cinerarias can be grown to great perfection, and the motto in the case should be, " If a thing is worth doing, it is worth doing well." Waterville, N. Y.
