August -in the Flower Garden
Plant-Houses.
Orchid Houses.-A number of the plants in these houses will now be in active growth, and for this reason must be kept warm. Among these may be mentioned those of the Phalae-nopsis family, which require a warm, even temperature. Dendrobiums will still demand plenty of heat and moisture. The house may be damped down with manure-water, using the same for the evaporating troughs. Keep a sharp look-out for thrips, which are very destructive to the young foliage. If any of the weevils are found cut away the parts affected at once and burn them, as nothing does more harm to Dendrobes than these minute creatures. Odontoglossums of the cris-pum section will generally have gone out of flower, and some will be starting to develop new growth. Any that require potting should be attended to before new roots are formed, as it is a great mistake to injure them by the process of transplanting to larger pots while in active growth. See that all pots and crocks used are quite clean. After potting shade the house a little more in bright weather, and keep the atmosphere closer for a short time, till the roots get active. Odontoglossum vexillarium, 0. Phalaenopsis, and some others of the same class, need a warmer temperature; from 60° to 65° at night suiting them admirably during this month. Keep up plenty of humidity in the atmosphere by constant damping down, and keep a sharp watch for red thrips, which finds its way into the young sheaths. Epidendrum vitellinum majus and some others will be improved by potting now. They should be grown with the cool Odontoglossums. Lycastes and Maxillarias will have completed their growth, so that they will need less water. The remarks that were given last month still apply to Cattleyas. When the nights are cold less air should be admitted, and a little fire-heat should be applied to cause a circulation of air.
Hothous Poinsettias, Euphorbia jacquiniaeflora, Amasonia punicea, and other winter-blooming plants, should be exposed to the sunlight for the purpose of ripening their shoots. This is a good time for potting Anthuriums in order that they may be well established before their flowering season comes round. Begonias of the section flowering in winter should also be potted on, and kept near the glass, to encourage a sturdy habit. As Caladiums finish their growth give less water, but do not dry them off too rapidly.
Where any palms need to be potted, perform the work during the current month so that they may become well rooted before the winter approaches. Ferns should also receive attention; particularly a batch of Adiantums for winter decorations should be potted into pots of a size larger, and seedlings should be pricked out into pans or pots for spring use. Take cuttings of Coleus and other plants of a tender nature, and root them in gentle heat so that they may grow bushy.
Greenhouse and Conservatory.-When the foliage of hard-wooded plants has grown firm, and before they are taken indoors, is a good time to look over them and rid them of insect pests. They may for this end be laid down on their sides, and washed with the garden engine or syringe, taking care to cleanse the under sides of the leaves. If they have two or three similar dressings they will be freed from insect plagues. Cuttings of show and fancy Pelargoniums that were put in last month will be ready for potting. When doing this choose a light, rich soil; do not over-pot, and use plenty of drainage material. Afterwards stand the plants in a cold frame or on the greenhouse shelf. Fuchsias may also be rooted now to give a supply of young plants for early display. Rochea falcata will now be in flower. When the flowers are over take off all young growths for cuttings, and insert them in a light, sandy soil; then put them on a dry shelf till rooted. Cactuses will have completed their growth, and therefore will need less moisture. These plants thrive with abundance of air and a dry atmosphere. There will still be a sufficiency of plants in flower for decorating the conservatory, as, for example, Liliun lancifolium, Hyacinthus candicans, Gladioli, Hydrangeas, Balsams, and many other plants of like character raised from seed; as these finish flowering fresh specimens should be introduced to keep up a gay appearance. As the nights get longer there will be more moisture in the atmosphere, therefore it will be necessary to guard against the damping off of flowers. To avoid this ventilate freely on all favourable occasions, and do not water in the evening in damp weather. Much mischief is often done among flowers by keeping the air too humid. A cool, dry, airy place, shaded from the sun, is most suitable for nearly all occupants of the Conservatory while in bloom.
Pits And Frames.
These structures will now be in great demand for the propagation of plants for bedding purposes. If Pelargonium cuttings are put in early there is not so much risk of their damping off in winter as when they are left till next month before the cuttings are taken. The young plants become well rooted, and consequently can absorb more moisture. Frames will also be required towards the end of the month for the protection of the more tender plants and bulbs, such as Freesias, Belladonna Lilies, Nerines, Tuberoses, and Vallota. As all these plants, excepting the first-named, flower in the autumn and winter, it will be requisite to cover them with lights in wet weather. Early Roman Hyacinths, Polyanthus Narcissus, and the earliest kind of Tulips should be potted and covered with ashes. If they can be plunged in a frame it will be so much the better, as they can then be had in bloom very early without forcing. Viola and other cuttings of herbaceous plants should be inserted so that roots may be formed before winter. Attend to previous remarks about Hydrangeas, Marguerites, Primulas and Cinerarias, Calceolarias, &c.
Flower-Garden And Pleasure Ground.
Outdoor work during this month is very heavy, so many plants requiring attention. Layer border Carnations at the beginning of the month. Transplant all seedlings of herbaceous plants that were sown last month. Cuttings of Pent-stemons, Antirrhinums, and some of the Phloxes may also be taken. About the middle of the month sow annuals for spring bedding, such as Swponaria calabrica, Limnanthes Douglasi, Virginian Stocks, Lasthenia californica, Nemophila, in-signis, Alyssum saxatile, Silene pendula, Myosotis, &c. Cuttings of choice alpines should now be inserted, as they will then make strong plants by next spring.
Violets for flowering in frames during winter should have liberal waterings with liquid manure to induce them to make plump crowns. Gather lavender and everlasting flowers where they are required for indoor use. Pay attention to staking and tying all herbaceous and other tall-growing plants. Lawns will now need constant attention, for the grass will grow apace; walks must be edged, and the weeds kept down. Flower-beds should have all the dead flowers removed. There is far more pleasure to be derived from a small place well kept than from a large one in a neglected state. Look to drains, and see that they are clear, or heavy thunderstorms may do considerable damage if the water is unable to get away. Shorten the shoots of Laurels, Hollies, and other evergreen shrubs that have grown too large for their position. Hoe and rake borders to keep weeds in abeyance.
