I generally sow my seeds about this time, or a little earlier, in shallow pans, in light sandy soil, without any manure. They are sown thinly and pressed down on the surface, so as just to be covered with the soil After a gentle watering, the pans containing the seed are removed to a hot-bed, where they remain until the young plants are about an inch in height At this stage, they are pricked out into the same sort of pans, an inch apart, adding this time one-third leaf-mold to the soil The plants are put into the hot-bed again until they hare attained the height of two inches, when they are taken oat of the pans, and shifted into 5-inch pots that have been well drained. The compost for this and their final shift consists of equal quantities of cow-dung two years old, leaf-mold, peat earth, and sandy soil. After potting; the plants are removed into a cold frame, with an eastern aspect The lights are kept close for a few days, and the plants are shaded from the mid-day sun until they commence growing. Air is then admitted, gradually at first, but as soon as I perceive the plants to be fairly in a pushing state, I ventilate freely. The sashes are, however, always put on when it rains, for nothing is so injurious to Primulas as water overhead, at any stage of their growth.
As they begin to fill their pots with roots, I give them liquid manure once a week, made from pigeon's dung. I permit the first flower stem to rise, but only for the purpose of judging of the merits of the flower. As soon as that is decided, the good flowers are picked out and when the pots are filled with roots the plants are finally shifted into 8 or 12-inch pots, and treated in precisely the same way as at the former shifting, and with the same situation and aspect They remain in the cold frame until the middle of October. After that they are brought into their winter quarters to flower in the green-house. As soon as the plants have stopped growing, I withhold the dung-water, as a continuance of it would be likely to destroy them in the winter months. - J.H., in London Gardeners' Chronicle, August 6.
