The Garden Under Glass

334 THE GARDEN UNDER GLASS Chrysanthemums. Only the large-flowering Chrysanthemums need be brought in to wards the end of the month. The bush ’mums and singles may often be safely left out until the end of October. Give the plants a liberal dusting of sulphur before bringing them in. This will check mildew, and a syringing of sulphide of potassium (one ounce to three gallons clear water) will do the same for rust. Sow a further supply of mignonette in pots if this sweet-scented flower is liked. Pot rooted cuttings of pelargoniums into 2|-inch pots. The old plants will now be breaking. Heliotropes intended for fall plants may be moved from 3-inch to 5-inch pots, also ivy-leaved geraniums for a similar purpose. Gloxinias may be dried off in a warm house beneath the staging. Fuchsias and begonias should also be dried off. If it is intended to grow sweet-peas for the greenhouse a sowing should be made this month in a cold frame. The best of the Stocks may now be moved to 7-inch pots. All bulbs for forcing are best potted by the end of this month. When only a few bulbs are used in the beds I would advise potting each separately in a 3-inch pot and plunging in ashes until the summer beds have been cleared. Thus the bulbs will have a start of about six weeks. Coleus cuttings rooted last month will be ready for shifting into single pots. The present is a good month for making up a frame for violets and planting them in it. Keep them as sturdy as possible by throwing the lights open on all but occasions of very heavy rain. Cauliflowers sown outside, also lettuces, may be pricked off into a frame to afford some protection during winter. Pot up arum lilies from the open ground, or re-pot them if they have been dried off in pots. Bring a few freesias to warmer quarters but do not attempt to force them hard. Mo ve such cinerarias as deserve it to 6-inch pots. Primulas andcycla-men should be brought from the frame to the greenhouse.
