“In the summer season, when the weather is warm, the plants must be frequently watered; but you should not give them large quantities at a time: you must also be very careful that the moisture is not detained in the pots by the holes being stopped, for that will soon destroy the plants. In very warm weather they should be watered twice or three times a week; but in a cool season, once a week will be often enough; and during the summer season, you should once a week water them gently all over their leaves, which will wash the filth from off them, and thereby greatly promote the growth of the plants. During the winter season, these plants will not require to be watered oftener than once a week, according as you find the earth in the pots to dry: nor should you give them too much at each time; for it is much better to give them a little water often than to over-water them, especially at this season.” _Insects._ After describing the white scale or mealy pine-bug (_coccus hesperidum_, L.) he says, “wherever these insects appear on the plants, the safest method will be to take the plants out of the pots, and clear the earth from the roots; then prepare a large tub, which should be filled with water, in which there has been a strong infusion of tobacco-stalks; into this tub you should put the plants, placing some sticks across the tub, to keep the plants immersed in water. In this water they should remain twenty-four hours; then take them out, and with a sponge wash off all the insects from the leaves and roots, which may be easily effected when the insects are killed by the infusion; then cut off all the small fibres of the roots, and dip the plants into a tub of fair water, washing them therein. Then you should pot them in fresh earth, and having stirred up the bark-bed, and added some new tan to give a fresh heat to the bed, the pots should be plunged again, observing to water them all over the leaves (as was before directed), and this should be repeated once a week during the summer season; for I observe these insects always multiply much faster where the plants are kept dry, than in such places where the plants are sometimes sprinkled over with water, and kept in a growing state. And the same is also observed in America; for it is in long droughts that the insects make such destruction in the sugar-canes. And in those islands, where they have had several very dry seasons, they have increased to such a degree as to destroy the greatest part of the canes in the islands, rendering them not only unfit for sugar, but poison the juice of the plant, so as to disqualify it for making rum; whereby many planters have been ruined.
