JULY
Antirrhinum.—A sowing in drills during the present month or August will supply plants for flowering next year. Transfer direct from the seed-bed to the positions where they are intended to bloom.
Calceolaria.—If more plants are wanted, sow again. Among the seedlings which we left last month just as they had been pricked off, it will soon be evident that there is a wide difference between the strength of the plants. As a rule, the most robust are those in which yellow largely predominates. These make bright and showy decorative plants, but the colours that are especially valued by florists will probably come from the seedlings which are weakly in the early stage. Hence these should be specially prized, and under skilful management they may be grown into grand specimens. The thumb pots for Calceolarias need careful preparation with crocks covered with clean moss or vegetable fibre, and they must be filled with rich porous compost. Transfer the plants with extreme care, and place them in a sheltered part of the greenhouse or in a shaded frame, allowing free access of air on the leeward side. If aphis has to be dealt with—and it is very partial to Calceolarias—fumigation is the best remedy. Choose a quiet evening for the operation; on the following day carefully water the plants and shade them from the sun.
Campanula.—The perennial varieties may still be sown, either in pans or in the open. Give them a good light soil, and do not stint the supply of water.
Cyclamens which are forward enough should be shifted into 48-sized pots. Follow up the process until all are re-potted.
Lobelia.—In pots or pans sow seed of the perennial varieties to provide plants for the borders next year. Pot off singly when ready, and protect in a cold frame through the winter.
Mimulus sown in the open ground will flower in the following spring. If possible, make the seed-bed in a moist retentive soil and in a shaded situation.
Primula.—To force the growth of this plant is to ruin it. The most satisfactory results are invariably obtained from specimens which have matured slowly, and have been treated as nearly hardy after the seedling stage. From this month up to the middle of September it will be quite safe to expose them freely, day and night, except in inclement weather. Even in the winter protection is only needed from frost, damp, and keen winds.
AUGUST
Annuals and Biennials, Hardy.—In the majority of English gardens the spring display of bulbous flowers is too often followed by a dreary blank, which is almost unredeemed by a touch of colour, except that afforded by the late Tulips and a few other flowers which are relatively unimportant. The brilliance of the Crocuses, Hyacinths, and early Tulips serves to throw into relief the comparative barrenness which follows. And the contrast is rendered all the more striking by the cheerful spring days. It is at this juncture that annuals and biennials from summer or early autumn sowings light up the garden with welcome masses and bands of fresh and vivid colouring. They are then so valuable that it is surprising they are not more commonly grown, especially as the cost of seed is very trifling. Even the transitory character of some of them is an element in their favour, for they do not interfere with the summer bedding arrangements. Such flowers as Pansy and Viola, however, produce a long-continued show of bloom.
