The Garden Under Glass

A GREENHOUSE CALENDAR 321 were grown from seed last year will now be in 9-inch pots, and will bear plenty of feeding if stood out in an open position. Begonias which seem to demand it may be moved into larger pots. The greenhouse will now need shading during bright, sunny weather, else there will be great difficulty in keeping the plants sufficiently moist, and moreover there are so many plants which object to much sunshine when in a greenhouse or frame. Chrysanthemums will now bear with standing outside, though it would be well to be prepared to cover them lightly at the approach of frost. Several of them will need short sticks to support them, the permanent stakes being put in when they have been put into their final pots. This operation need not be delayed if the plants have well filled their 6-inch pots with roots. The bush and single ’mums should have their points pinched out, but not the late-flowering ones. Those grown for large biooms should be pinched during the third week if they have not already made natural breaks. Old tree carnations, which will now be getting dilapidated, may be set outside, and will furnish growths for cuttings or layers later on in the summer or early autumn. The young ones may be set outside on a bed of ashes, to be covered during frosty and wet weather. Any that are sufficiently advanced may be removed to 7-inch pots, in which they should make fine plants. I find that zonal geraniums intended for winter flowering do well in the same soil as Chrysanthemums, and when this has been prepared a portion should be set apart for them, but it will probably need chopping over again as the soil is left fairly lumpy for the Chrysanthemums. Pot up young dahlias rooted from cuttings. The old stools may be planted out in the open after they have been duly hardened. The best of the East Lothian Stocks will bear removal to 5-inch or perhaps even 6-inch pots, and will, if x
