'The small Otaheite Orange, so useful for winter flowering, should, when out of bloom, have its growth pushed on in a little warmth. This plant is subject to scale, and before any young growth is made they should be thoroughly cleansed with insecticide, using the sponge in preference to the brush, the latter being liable to scratch the leaves. Plants of varieties of large growth that have flowered should be similarly treated. Oranges of all kinds, whilst making their growth, must he well supplied with water, especially overhead, and be also slightly shaded from the sun. The orange is a plant of comparatively easy growth, and naturally able to withstand a good deal of bad treatment without being killed outright; and to this, no doubt, may be attributed the indifferent condition in which they are often seen. When in a bad state the roots are generally few, and almost dormant at a time when they should be ramifying in all directions; when thus stunted and unhealthy the best course is to turn them out of their pots, reduce the balls considerably, put them in smaller pots, and place at once in moderate heat with a close moist atmosphere until the roots are unmistakably active and the growth is made: plants in such condition will be much benefitted by a moderate bottom - heat of about 70°.- Gardener's Chronicle
