THOBBUEn's CATALOdUK OF FLO WE It SEEDS. 8 strength to the plants, is to sow the seeds in pots early in March, placing them in a warm green-house or window, or plunging them in a moderate hot-bed, carefully protecting them from the cold, shading them from the midday sun, and watering with a finely pierced watering can.The seed should he sown in very light sandy compost, and the pots well drained by placing broken earthenware and rough sods In the bottom. The finer seeds must not he planted more than an eighth of an inch deep, and the soil must he pressed down closely over them. Water frequently particularly, if the house or frame is very warm. As soon as the seed leaf is fully developed, transplant into small pots, three or four in each, and when they have acquired sufficient strength transplant into the flower beds-not, however, before the middle of Maw « GHEE'S-HO USE SEEOS ((/.)-Should be sown as directed for Tender Annuals, in pots, pits or boxes-be kept in the house, carefully watched, slightly watered occasionally, and sheltered from the hot sun till strong enough to transplant. Most of these varieties may be sown at any season of the year.The smaller seeds of Green-Hmise Plants are sometimes difficult to germinate, unless great care is taken in the mode of sowing. Thence the supposition is produced that the seed itself is not good, whereas the fault is not in the seed, but in the treatment.Fine seeds of this description should be sown in leaf-mould or peat earth, with some silver sand added to it, which should he pressed firmly down in the seedpan. or pot, and made perfectly level at the top, so that the mould may not afterwards sink materially with watering, and thereby carry down the seed with it to a greater depth than that at which it is sown. Sow the seed very thin, and cover very slightly with a little of the compost or with some of the silver sand. By this method the difficulty of succeeding with fine seeds will be removed. As soon as the young plants have two leaves, they should be transplanted into similar compost in another pot. To do this, do not pull them out of the seed-pan, but lift them out with the point of a knife under their roots. By that means, the young, minute roots are taken up without breaking. After transplanting, they should be kept in a shady part of the green-house for a few days until they are established in the new soil.There are many minute plants, from the finer seeds, killed by drenching them with water whilst very young. One way to avoid this is to give the water by dipping a clothes-brush in water, shaking off the greater part of the water from the brush, and then (holding the brush over the seed-pan) drawing the hand over the bristles several times, which will cause the water to be thrown on the young plants almost like dew. Whilst in the first stage of their existence, plants require moisture in a minute quantity, often repeated, and not in such large quantities as to saturate the soil in which they are growing.1'HIM I 'LA S. -These charming plants may be brought to th...
