H. A. C— Ala. 



There is no question in my mind that 

 your trouble is caused by thrips. The 

 remedy for this pest is spraying with 

 nicotine. If you nad sprayed regularly 

 during the winter, as recommended in 

 thete columns, you would not be having 

 this trouble now. You are likely to 

 have a hard fight. Spray every other 

 day for a couple of weeks, then reduce 

 to twice weekly, and, if you see that 

 you are getting control, you can reduce 

 to one application each week.

OOVESED WITH LEAP-SPOT. 



I am mailing to you under separate 

 cover a carnation taken from my beds. 

 The plants appear to be diseased. 

 Blindly examine the sample and see 

 whether you can discover the trouble 

 and advise me as to its treatment. 

 W. F.— Va. 



The specimen submitted was simply 

 covered with the common carnation 

 leaf-spot. If the whole bed is as badly 

 affected as this plant, I would advise 

 throwing the plants out and burning 

 them. It is probably too late to try 

 to doctor them up, as the season would 

 be over by the time you could get them 

 into any kind of shape. If you think 

 it worth while, however, you can use 

 Bordeaux mixture, spraying the plants 

 heavily after picking off the spotted 

 leaves. A. F. J. B.

r am sending some carnation leaves 

 and buds which seem to be diseased. 

 At first the spots appeared on the buds. 

 After two weeks I noticed that the 

 trouble was spreading to the leaves, 

 and by the time the flowers were fully 

 opened the calyx was all dry. The 

 plants are being grown in the fleld all 

 the year around, here in southern Cali- 

 fornia. This is the first ^^ear I have 

 noticed anything of this kind. Kindly 

 let me know what it is and how it can 

 be cured. G. F. M.— Cal. 



The specimens submitted were cov- 

 ered with fairy ring. This disease, like 

 all the carnation spot diseases, is 

 caused by too much humidity. I would 

 suggest, if the plants are not too badly 

 af^eted, that you cut away all the 

 growth bearing these spots. Then 

 spray the plants heavily with Bordeaux 

 mixture. Picking off the spotted 

 leaves is a tedious task, but it is un- 

 doubtedly the most effective wav to get 

 rid of the disease. Bepeat the Bor- 

 deaux spray every ten days until you 

 have the disease under control.

Can you tell me what vines to grow 

 for shade f One of my customers wants 

 vines that will give heavy shade the 

 first summer they are planted. He does 

 not care for hardy vines, but would 

 prefer something that would freeze out 

 in winter. Should these be started in

shade as any annual climber you can 

 start. Sow the seeds in pots this 

 month. Keep the stalks tied up, as 

 they grow quickly. The annual hop, 

 or Humulus Japonicus, also makes quick 

 growth and gives an excellent shade. 

 Another useful climber for such a pur- 

 pose is Echinocystis lobata, or Cali- 

 fornia cucumber. Soak the seeds in 

 warm water twenty-four hours before 

 sowing and they will start more rapid- 

 ly. Scarlet Eunner beans are good, 

 as are the Japanese morning glories 

 and moonflowers. The ornamental 

 gourds are sometimes used in this way. 

 They are excellent for covering arbors 

 or pergolas. C. W. 



MASSACHUSETTS MABGXTEBITES. 



One of the largest and most success- 

 ful growers of yellow marguerites in 

 the vicinity of Boston is James 

 Wheeler, of Natick, Mass. Although 

 carnations are Mr. Wheeler's specialty, 

 he also grows marguerites successfully, 

 as the accompanying photograph of 

 two beds, taken in February, indicates. 

 These beds are each 300 feet in length, 

 and contain several thousand plants. 

 It has been asserted that yellow mar- 

 guerites, to flower successfully in the 

 winter months, must be in pots or 

 boxes, or at least have their roots 

 much restricted, but Mr. Wheeler culti- 

 vates young plants in solid beds and 

 flowers them beautifully. As to the 

 quality of the flowers, it is only neces- 

 sary to say that they bring as much 

 money as carnations in a critical mar- 

 ket and that only a short time ago they 

 were awarded a cultural certificate by 

 the Gardeners' and Florists' Club of 

 Boston. W. N. C. 



operation, in order to start away again. 

 The best time to do this work is during 

 the month of April, when the plants are 

 usually getting into more active 

 growth. Be sure to ram the new soil 

 firmly in the pots; then water thor- 

 oughly, so that the soil will be moist- 

 ened through. Place the plants in a 

 shaded greenhouse in which a night 

 temperature of 65 degrees is kept, and 

 maintain a moiat atmosphere by syring- 

 ing every bright day, being careful not 

 to ventilate too freely in windy weather 

 until the plants have a chance to make 

 some new roots. W. H. T. 



OUTDOOR SFECIOSUM LILIES. 



Kindly tell me how to grow Lilium 

 speciosum album, Melpomene and 

 rubrum outdoors, and how to care for 

 the bulbs from year to year. Do they 

 have to be lifted in winter t

TBIMMINQ PALM BOOTS. 



Will you please inform me whether 

 it would be advisable to cut the roots 

 of fan palms and kentias, which are 

 in too large pots to be handled easily 

 and which I wish to place in smaller 

 potsf If so, when would be the best 

 time and what care should be given 

 the palms afterward f 



A. U. M.— HI. 



The roots of palms may be pruned to 

 some extent in order to reduce the size 

 of the ball when repotting, but they 

 require a little extra care after this 



The best time to plant these lilies 

 outdoors is in late fall, as soon as the 

 bulbs arrive from Japan. This is us- 

 ually late in November. The ground 

 in which they are to be planted can be 

 covered with straw or leaves to ex- 

 clude the frost until they arrive. If 

 the planting was not done in the fall, 

 the next best time is in the spring. 

 Cover the bulbs to a depth of nine 

 inches; if you have deep soil, twelve 

 inches will be even better. Place some 

 sharp sand above and below them. Do 

 not use any fresh manure in the soil 

 where lilies of any kind are to be 

 planted. You can, however, spread 

 some on the surface after planting, if 

 you wish. These lilies are perfectly 

 hardy in your state and do not require 

 to be lifted in the fall, but they can 

 be given a mulch of leaves or old 

 strawy manure when the ground has 

 become frozen. C. W. 



WISTABIAS FBOM SEED. 



At what age will wistarias bloom 

 from seed! E. C. C. — Okla. 



Usually when from 3 to 4 years old. 

 However, a better and more speedy 

 way of securing plants is by layering. 

 Some wistarias never flower, and I be- 

 lieve it is a fact that a non-flowering 

 variety is on the market. C. W.
