dust it on the affected parts with flower of sulphur, and set 

 them for a few days where they will be sheltered from the 

 wind, after which wash off the sulphur. If the cure is not 

 complete, renew the dose. Always sweep out and dry up 

 the water in the house when any is spilt. The succulent 

 plants will be in want of a little water about once a week, 

 but do not over-water them, as there is not heat enough to 

 absorb much moisture. If the soil is damp, it is quite suf-

ORANGES, LEMONS, &c., 



Will, in many instances, about the end of this month, be 

 showing flowers or flower buds. They must, under these 

 circumstances, have plenty of air to prevent them from 

 falling off when entirely exposed. The reason that we see 

 so much fine blossom falling to the ground where the trees 

 are brought out of the house in May, is from the confine- 

 ment they have had. Where there is a convenience of 

 giving air from the back of the green-house, it should 

 always be given in mild days, especially in those houses 

 that have a recess back from the top of the sashes, for even 

 if the sashes are let down every day, still the house will 

 not be properly ventilated. Any plants that are sickly and 

 intended to be planted in the garden next month to reno- 

 vate their growth, may be cut back (if not already done) 

 as far as is required to give the tree a handsome form, tak- 

 ing care not to cut below the graft or inoculation. Let the 

 operation be done with a fine saw and sharp knife, smooth- 

 ing the amputations that are made by the saw ; and if they 

 are large, put a little well-made clay over the wound, to 

 prevent the air from injuring it. Bees'-wax and turpen- 

 tine are preferable to clay, not being subject to crack or fall 

 off by the weather. 



If there are any Lager strcemias, Pomegranate or Hy- 

 drangeas in the cellar, they should be brought out about 

 the first of the month, and planted in their respective situa- 

 tions. Give the Hydrangea a very shady spot. It does 

 not require much sun, provided it has plenty of air, and 

 do not plant it into soil that has been lately manured. A 

 large plant must have great supplies of water in dry wea-
