April.] GREEN-HOUSE WATERING. 261 
ceptible. In order to strengthen the plants, and keep 
them from becoming drawn and spindly, admit large por- 
tions of air every mild day. Indeed, there will be very 
few days in this month that a little air may not be given, 
always observing to divide the quantity regularly over the 
house, in cool nights closing in time. About the end of 
the month an abundance of air is indispensable, leaving 
the sashes and doors open every mild night, that the plants 
may be inured to the open exposure they will have in a few 
weeks. 
WATERING. 
As the season advances and vegetation increases, the 
waterings will require to be more copious and more fre- 
quent. Look over all plants minutely every day, and with 
judicious care supply their wants. Those that are of a 
soft shrubby nature, and in a free-growing state, will require 
a larger portion at one time than those of a hard texture, 
which may only want it every two or three days. The 
weather and situation, in some instances, may require a 
modification of these directions. Plants in general will not 
suffer so soon from being a little dry as from being over- 
watered. The health and beauty of the foliage of the plants 
may be much improved by syringing them freely three 
evenings in the week, except in moist weather, when it 
ought not to be done. The ravages of many insects also 
will be retarded, especially mildew and red spider, which 
will be entirely destroyed. If the red spider is on any of 
the plants particularly, take them aside evening and morn- 
ing, and give them a good dashing with water through the 
syringe. Where there is mildew, after syringing the plant, 
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- 
ficient.
