THE GARDENERS' CHRONICLE OF AMERICA. 



frequently. The rougher or hairy-leaved plants should 

 not be sprayed so frequently or heavily. A few kinds, 

 such as Rex Begonia, gloxinias, tuberous-rooted begon- 

 ias, having hirsute or hairy foliage, are best not sprayed 

 at all, if it can possibly be dispensed with. 



There are very few plants that can be syringed or 

 spread overhead when in full bloom without danger or 

 injury to the flowers. The tender texture of the petals 

 of most flowers are very easily injured if allowed to 

 remain in a damp condition for any length of time. 

 If the foliage of plants in flower has to be sprayed, it is 

 best to spray froin underneath rather than over the top. 

 The moisture will thus reach the part of the foliage where 

 insect pests are usually found, and it will not injure the 

 blooms so much as overhead spraying. An angle nozzle 

 on the syringe or hose that will give an up-cast spray is 

 advisable for greenhouse work. 



The temperature of the greenhouse should not be al- 

 lowed to rise unduly high on flowering plants when they 

 have been syringed or spra)-ed. A high temperature and 

 a very humid atmosphere will often damage many of the 

 more tender blooms without actual contact with water. 

 Open the ventilators a little to allow the heated humid 

 air to escape after spraying flowering plants, so as to 

 avoid damage to the blooms. The best time to spray 

 flowering plants is in the morning on fine bright days. 



It is scarcely possible to have a too humid atmosphere 

 for foliage plants. The treatment of these in regard to 

 spraying is directly opposite in many respects to that of 

 flowering plants. Both overhead and underneath spray- 

 ing can be indulged in freely with all kinds of foliage 

 plants, such as palms, crotons, dracaenas, and similar 

 plants. The best time to syringe or spray these plants is 

 in the afternoon while the sun is still shining a little on 

 the house. By spraying thoroughly at this time of the 

 day and closing the ventilators up tight, a dense humid 



vapor almost like steam is caused that is very beneficial 

 to the plants as well as helping to keep down the insect 

 pests most common and injurious to them, viz., thrip, 

 red spider, and mealy bug. The floors and heating pipes 

 can also be dampened at closing-up time to increase the 

 humidity. If foliage plants are sprayed in the morning, 

 except perhaps in very cold weather in winter, ventilation 

 must be given before the hot sun strikes the house, or 

 the plants must be shaded in some way to prevent "scald" 

 or "burning" of the foliage. Many fine palms and sim- 

 ilar plants are often ruined, especially in early spring, for 

 want of shade or ventilation to prevent this scalding or 

 burning of the foliage. 



It becomes necessary to spray plants with liquid in- 

 secticides sometimes as a remedy or preventive of insect 

 pests or disease. Spraying has to a very great extent 

 superseded fumigation in greenhouses for this purpose, 

 being more direct in its efi'ect on many insect pests and 

 diseases, more economical to use, and often less in- 

 jurious to many forms of plant life than fumigation. 



In spraving operations, as with everything else in con- 

 nection with horticultural operations, do not neglect do- 

 ing it until it is too late. "An ounce of prevention is 

 better than a pound of cure." And when spraying, spray 

 thoroughlv. — Canadian Horticulturist. 



FOREST THOUGHTS. 



May each new leaf an idea bring 

 Of love of woods, a bird to sing, 

 A flower to bloom, a tree, a spring. 



The arms of trees in reverence raise 

 Their supplication and their praise. 

 The praver to Man, the praise to God
