In many places arrangements are now made for growing plants for cut flowers. There are benches for holding the plants which are grown in the earth, and not in pots. In some instances plants are grown in these beds all summer, the glass being shaded from the hot sun. This is especially the case with young roses from which flowers are desired in the winter, and also with Bouvardia - but sometimes, and indeed generally, the plants are grown in the open ground and, at this season, carefully lifted, and placed in the beds of earth prepared for them. In lifting them, great care has to be exercised to keep them from wilting, for, although the drooping heads will usually come up again, it is always at some loss to the future well-being of the plant. To prevent wilting, it is best to take up the plants after a soaking rain, so that the earth will adhere to:he roots in a little ball, and especially to keep the glass of the house as dark as possible for a few days. It is light, quite as much as a dry atmosphere, which takes the moisture out of a transplanted plant. Carnations, Bouvardias, Roses, Callas, Heliotrope, and Mignonette, still continue to be the great stand-bys of the cut-flower men, though all sorts of specialties, as "fancies." are continually coming up.
Last winter there was quite a run on various kinds of common European Chrysanthemum, or "Da-sies," as they are commercially called. The various forms of the Chrysanthemum tricolor, were especially much sought for. Many plants that have been turned out of pots to pasture in the open air during summer, will have to be repotted during the month of October.
In taking up things from the ground for potting, care should be taken to have the pots well drained with pieces of potsherds over the hole. The more rapidly water passes through the soil, the better plants will grow. Pots could be made without holes, and the water would all go through the porous sides in time; but that is too slow a way, so we make a hole to admit of its more rapid escape, and we place the broken pots over the hole to make a vacuum, which assists the object of the hole. In very small pots, or with plants which have strong enough roots to rapidly absorb all the moisture they get, and speedily ask for more, "crocking " is not necessary.
There are but few things in the greenhouse that will require special treatment at this time. Camellias and Azaleas, as they cease to grow, will require less water; but it is now so well known that moisture is favorable to growth, and comparative dryness favorable to flowering, that we need do no more than refer to the fact.
Bulbs for flowering in pots should be placed at once. Four or five inch pots are suitable. One Hyacinth and about three Tulips are sufficient for each. After potting, plunge the pots over their rims in sand under the greenhouse stage, letting them remain there until the pots have become well filled with roots, before bringing them on to the shelves to force.
