But little may be said of the greenhouse this month. Watering, ventilating, and fumigating, (or the use of tobacco in other forms for destruction of aphis), must be attended to. Keep the atmosphere of the greenhouse moist. The plants from the greenhouse that may have been plunged out-doors, must be watched when they require repotting, and where the roots have run through the pots, they should also be occasionally turned round, to break them off, for if this is not done now, it would seriously injure the plant in fall when the roots have run through the pot and deep into the soil, as they often do. Plants such as dahlias, roses, gladioluses, as well as many herbaceous perennial and annual plants, will now require staking; be careful to proportion the size of the stake to that of the plant, and do not tie it too tightly. Stakes painted green look best, and the square are nearly as good as the round ones, and much cheaper. Carnations and other plants that are throwing up flower-stems, if wanted to flower in winter, should be cut back.
If there are any signs of mildew on the grapevine leaves, dust them over with dry sulphur, choosing a still, warm day. The fruit will now be gathered from the strawberry vines, and if new beds are to be formed, the system recommended of layering the plants in small pots is the best; see Strawberries.
Where apples, pears, peaches, etc., have set fruit thickly, thin out one-half or two-thirds of the young fruit, as by doing so you will get at least an equal weight and much finer fruit The same is true of grape-vines and all other fruits that have set thickly; where thinning out is practicable, it will always be beneficial to practice it
Plants of cabbages, cauliflowers, celery, and all similar varieties of vegetables wanted for fall or winter use are best planted this month, though in some sections they will do if left until next See directions given under these separate heads. Sweet corn, beans, cucumbers and lettuce may yet be planted for late crops, and in some sections ruta-baga turnips for the main winter crop. Tomatoes should be kept tied up to stakes or trellises, and sweet potatoes must be hoed so as to prevent the vines rooting at the joints.
