April.] THE GREEN-HOUSE. 353 
the green-house, and let every thing in and about it appear neat and 
lively. 
When any large leaved kinds have contracted foulness, wash 
them, one by one, with a sponge dipped in soft water; the small 
leaved sorts may be taken out of the house, in a warm day, and 
water poured over them out of a watering pot, which will not only 
wash off the dust but greatly refresh them; then replace them as 
before. 
Heading down Shrubby Plants. 
Myrtles, oranges, lemons, geraniums, and several other woody 
plants that have got into a bad state of health, may now be headed 
down; observing that any of the budded kinds should not be cut 
oft' below where they were worked, except in cases of absolute 
necessity, that is, when the wood is either dead so far, or in such a 
state that no hopes remain of its producing new shoots — under such 
circumstances you may head them down to the fresh wood. 
By this means they will put out plenty of strong shoots, near, 
or from the stems, and form full regular heads in two or three 
months. 
Shifting or fresh earthing the plants, as before directed, will be 
necessary upon this occasion. 
Inarching. 
Towards the latter part of this month you may inarch oranges, 
lemons, citrons, limes, shaddocks, pomegranates, and almost every 
other kind of shrubby plants, agreeably to the directions given in 
page 256. 
By way of curiosity, or as required, you may inarch a branch of 
an orange or lemon tree, that has young fruit on it, on one end of 
the common seedling stocks: it will be well united by the end of 
August, when it may be separated from the mother plant, in a full 
bearing state. 
Sowing Seeds of Green-House Plants, Sfc. 
As early in this month as possible, sow the seeds of geraniums, 
myrtles, oleanders, coronillas, lemons, oranges, balm of Gilead, 
aloes, cannas, buddleias and cactuses; callicarpa, caparis, celcias 
mimosas, mesembryanthemums, centaureas and chrysocomas; cine- 
rias, cistuses, coluteas, cyclamens, dolichoses, ericas and euphor- 
bias; ferrarias, gardenias, genistas, heliotropiums, indigoferas and 
lyceums; melias, melianthuses, oleas, passifloras, solanums, and 
proteas salvias, silenes, spartiums, teucriums, yuccas and xeran- 
themums, with many others. For the method of sowing them see 
page 309. Many kinds will not vegetate for two, three, four or six 
months, and some not sooner than twelve; therefore attend the 
pots carefully, and your patience and trouble will be ultimately 
rewarded.
