The Garden Under Glass

A GREENHOUSE CALENDAR 331 quarters. Calanthes will now be showing their flower spikes. Vigorous bulbs will generally throw up two spikes and sometimes small spikes are thrown out from some way up the bulb. They may still be fed liberally until the leaves begin to yellow. At that time they should be watered less frequently and may also be set more closely together. Chrysanthemums will fast be showing their buds, and all these should be retained, the side growths which cluster round the bud being pinched out. Beware of earwigs about this time. They do much damage by eating the buds. They must certainlybetrapped. If not already done, a top-dressing should be given to them. All side growths should be religiously pulled out. Border camation and Malmaison layers which are rooted may now be potted into 3-inch pots in sandy soil, and be put back into a frame. Pot winter-flowering Stocks to 5-inch pots, and after a week pinch out the points of each. Sow schizanthus and Clarkia elegans for flowering in pots in the spring. Leaf cuttings of gloxinias will now be throwing up their growths, and the old leaf will soon die off. They may safely be left in the box until the end of the year. Until the end of this month all flowers should be pinched off such winter-flowering subjects as zonal geraniums, salvias, primulas, cyclamen and Lorraine begonias. All these plants will bear liberal feeding with manure-water, and occasionally a dusting of Clay’s. So also will eupa-toriums and. scented-leaved geraniums. Move Primula obconica to 6-inch pots and. keep them in a cool and fairly shady situation. Get up some plants of Canterbury bell from the open garden and pot singly in 3-inch or three plants in a 6-inch pot. Make out the order for bulbs for forcing, else the best will be sold. Do not rely on bulbs bought at sales. They are rarely satisfactory and reflect no credit on the grower.
