Plants to be wintered under glass should all be safe from frost, neatly arranged in their winter quarters, clean and orderly. However hardy any plants in pots are (which have to stand the tear and wear of forcing), they should at least have protection in severe weather. If in pits under glass-lights so much the better. The whole stock of Azaleas, Rhododendrons, Roses (China, Noisette, and Teas, especially), Lilacs, Kalmias, Deutzias, Dielytras, bulbs of sorts, may be potted for succession. Syringas, Cherries, double and single, Kalmias, Lily of the Valley, and others well known, should be arranged in lots, in order to select from the earliest of the stock suitable plants for forcing, and this work will soon require attention. Where a gay conservatory and cut-flowers are matters of great request, Chrysanthemums should now be all secure by stakes, and taken under glass to flower, giving them plenty of light, air, and liquid manure. Calceolarias may require potting, and should have plenty of air and light now. Fire-heat is much against their wellbeing. Cinerarias and Primulas also require cool airy treatment. Frosty winds are very injurious to this class of plants. Cyclamens growing planted out in frames should be potted, if not already done.

Heaths, Epacris, and the whole class of New Holland hard-wooded plants, should be placed where there is plenty of air and light. A little fire-heat, with fresh dry air on, may be necessary to keep greenhouses and conservatories healthy; but should only be used as a necessary evil. Cleanliness in every respect is indispensable to the health of plants. Pelargoniums cut down and growing freely, may be potted into small pots, first reducing the roots. Keep them cool, and water with much care. Mildew may appear on some plants; sulphur sprinkled on the pest will soon eradicate it. All surfaces of pots should be free from moss and weeds, and the soil kept porous. Fumigate with tobacco, to destroy aphis wherever it appears. At this season choice plants in flower for show-house are not very plentiful; but there are so many with fine foliage and graceful habit, that there need be no lack of interest in this structure : neatness and order and absence of crowding always do much to help the appearance of plants - the reverse of this robs them of much of their beauty.

Plants in flower now are autumn Heaths. Camellias which were forced early, Roses, Pelargoniums, Fuchsias, Mignonette, Violets in pots, Salvias, Valottas, and others, mixed with Phormiums, greenhouse Ferns, Palms, Dracaenas, Corda-lines, etc, make a good display. In stoves the stock of winter-flowering plants should have the best positions for light; shading everywhere may now be removed. All staking, surface-cleaning, washing of lights, sponging of leaves and stems, drainage, pot-washing, should be done thoroughly now, and cleanliness may be an easy matter afterwards. Plants coming forward for flowering are Euphorbias, Begonias, Justicias, Eucharis, Gardenias, Gesnerias, Scutellarias, Thyrsacanthus, Calanthes, Poinsettias, Libonias, and others. Stove-heat may not be over 65° at night. M. T.

Plant-Structures #1

Chrysanthemums will be gay to end of month. They then should be hardened gradually for the supply of cuttings. Most plants date their success from the cutting or seedling stage. Azaleas, Camellias, and some of the stock of forced plants will take the place of Chrysanthemums, where there are means to bring forward the numerous plants often referred to for conservatory decoration. Better to err on the side of low temperature at this season than the reverse - small batches taken in often, are preferable to large quantities at longer periods. All plants to be forced should be under protection of some kind. Never take frozen plants into heat; all forcing should be gradual, and as natural as possible. At all times take every advantage of sun-heat. Greenhouse plants of the hardwood class should have plenty of air when weather is mild. Use fire-heat to expel damp, and the temperature need not fall much below 40°. About 45°, all other things being equal, will suit most plants in the daytime - at night 6° or so less in severe weather is all the better for the plants. Cinerarias, Calceolarias, Cyclamens, and Pelargoniums require plenty of light and air, and damp must not be confined in the structure. The last named may be kept drier and more airy than the others.

Mildew must have no place, but have sulphur dusted over it. Vermin and decaying matter must not be seen. In stoves the treatment varies little from last month: numbers of the plants grown specially for Christmas decoration will now be well forward. Among the chief of them are Poinsettias, Begonias, Euphorbias, Scutellarias, Calanthes, etc. Gloxinias may be started if wanted early - also Achimenes, a few Caladiums, and others. Mixed stoves may be very "quiet" at this season. Temperatures need not be over 55° at night, and 60° by day. Thrips are always very active at this season : keep the sponge going. M. T.
