SCALE ON NEFHBOLEPIS. 



You will find enclosed a fern leaf 

 that is infested with scale and with 

 white objects that look like the eggs 

 of the scale. Please let me know what 

 is the best means of getting rid of 

 these. I also notice that there are 

 small black ants crawling on the fern. 

 Have they anything to do with the 

 presence of the scale on the plants?

Here's why The Eeview not only holds 



its patronage but steadily adds to it: 



"We sold up in a hurry on all the rose plants 

 we had to offer, THANKS TO YOU. — Slman- 

 ton & Pence, Falls City, Neb., June 27, 1913. 



The nephrolepis frond enclosed with 

 this query was badly infested with 

 scale. The first thing to do with plants 

 in such a condition would be to cut 

 off and destroy all fronds that are in 

 «s bad a state as this. Then dip the 

 plants in a nicotine solution. A solu- 

 tion of Nico-fume, one part to 300 

 parts of water, would be safe to use, 

 though it might affect the tips of the 

 young fronds to some extent. If the 

 plants are protected from the sun after 

 dipping them in the solution, there is 

 less likelihood of injury to the foliage, 

 but it is probable that several dippings 

 may be needed to overcome the pests. 



The ants were feeding on the sesde 

 insects and, incidentally, would spread 

 them from plant to plant in order to 

 keep up a supply of food for them- 

 selves. W. H. T. 



PIJ^NTS ATTACKED BY THEIPS. 



I am sending under separate cover 

 two tuberous-rooted begonias and one 

 celosia, all grown in the same house. I 

 should be greatly obliged for any in- 

 formation as to what is the matter with 

 them. The begonias were doing splen- 

 didly until about a week or ten days 

 ago, when this trouble started. Some 

 are considerably larger than those sent 

 and they are all affected except two or 

 three. There is, however, a later batch 

 in the same house which is not affected. 

 We keep them shaded and ventilate 

 fairly well, but close down tightly at 

 night. About twenty-five out of sev- 

 enty-five of the celosias are affected like 

 the specimen sent. H. J. 



"THANKS TO YOU." 



The publication with the smallest cir- 

 culation usually is the one to make the 

 loudest claims, but the real test for the 



Both the tuberous-rooted begonias and 

 the celosia, or cockscomb, were simply 

 smothered with thrips. These pests will 

 soon destroy a fine batch of begonias, 

 gloxinias, or in fact almost Kny plants 

 of a soft-wooded nature, and will also 

 attack some with harder wood. They 

 always breed and increase most rapidly 

 in an atmosphere which is too arid. 

 Plants affected as yours are will be of 

 no value whatever this season. Your 

 later batch will, unless carefully looked 

 after, share a similar fate. 1 would 

 advise throwing away all the earlier 

 batch of begonias and celosias. Dip the 

 late plants in tobacco water or some 

 other insecticide. Keep a moister at- 



mosphere in the house and do not close 

 the ventilators tightly at any time. 

 Spray among the plants freely, but do 

 not wet the leaves if the direct sun's 

 rays will strike them, as they are liable 

 to become scorched. Dip the plants 

 once a week and probably you will be 

 able to flower them satisfactorily.

CYCLAMENS TURNING YELLOW. 



I put my cyclamens outdoors in a 

 rather shady place, with the pots 

 plunged in the ground up to the rims, 

 but all of the leaves turn yellow except 

 the center ones. Is this just natural, or 

 is there something the matter with the 

 plants? J. S. 



If the cyclamens are flowering plants 

 which you are intending to carry over, 

 it is natural for them to lose a part of 

 their foliage now, as they need a mod- 

 erate rest through the summer, when 

 they lose most of their foliage. On the 

 other hand, young plants raised last 

 summer or fall should not lose their 

 foliage in this way. The best place for 

 them for the next three months is in a 

 coldframe protected by lath shadings, 

 plunged or partly plunged in coal ashos. 

 Keep the sashes well tilted all the time 

 and on hot days remove them and mere- 

 ly keep the shades over the plants. 

 Spray freely when hot. The plants can 

 be left out until the end of September.
