SPOT ON VIOLETS. 



What is the cause of white spot on 

 violet leaves, and the remedy? 



J. W. S. 



We are unable to tell you the cause 

 of spot on violet foliage, nor can we 

 give any reliable remedy. In the case of 

 single violets, the spotting is rarely suffi- 

 ciently serious to injure the plants, al- 

 though we have seen instances where 

 even these have been well-nigh denuded 

 of leaves. Picking off badly affected 

 foliage usually suffices for the singles. 

 In the case of doubles, particularly Marie 

 Louise, the best of the blues, whole 

 benches and houses are ruined each year 

 by spot. Damage is least when the plants 

 are grown where they are to flower, and 

 usually most serious with late planted 

 stock. Cleanliness, picking off affected 

 foliage, plenty of fresh air night and 

 day, and all possible sunshine should be 

 the treatment given. Do not coddle, but 

 let the night temperature be as near 40 

 degrees as possible. C. 



BARONNE ROTHSCHILD VIOLET. 



Last season F. W. Fletcher Co., Au- 

 burndale, Mass., and C. H. Totty, Madi- 

 son, N. J., jointly introduced Violet 

 Baronne Eothschild, shown in the ac- 

 companying illustration. This is a single 

 variety which originated at the Fletcher 

 establishment. Exhibited at the Boston 

 flower shows prior to its distribution in 

 the trade, it took the eye of all the 

 growers, so that when it was sent out 

 all the available stock was quickly taken 

 up by those who wished to give the va- 

 riety a trial this season. Mr. Fletcher de- 

 scribes it as much more floriferous than 

 Princess of Wales, and the foliage is 

 smaller than in that variety. 



Thus far this season the plants sent 

 out last spring have done nicely with 

 most of those who bought stock of the 

 novelty, and there are many who think 

 they have here a formidable rival of 

 Princess of Wales, which heretofore has 

 practically monopolized the market for 

 single violets.

kindly inform me if there is 

 can do to exterminate spot 

 my double violets? I have 

 the leaves as fast as the spot 

 still it comes on. Some of 

 that were badly affected I 

 out. F. M. B. 



Having tried about every imaginable 

 reme(h' for spot on double violets, I am 

 Toreed to confess that nothing seems to 

 check it once it has appeared in a viru- 

 lent form. Picking off affected leaves 

 helps in some djegree, but I have had 

 little success with spraying solutions, 

 such as Bordeaux mixture, sulpho-napthol 

 and permanganate of potash. Cleanli- 

 ness, stirring of the surface soil, an 



abundance of pure air and a night tem- 

 perature as near 40 degrees on cold 

 nights as possible, are conditions which 

 double violets like. 



Double violets are best grown in the 

 beds or benches in which they are to 

 flower. This plan is adopted in the noted 

 Ehinebeck section on the Hudson river. 

 If planted outdoors, fhey should be lifted 

 much earlier than the singles, which lat- 

 ter should be left out until they have had 

 one or two freezings. C. W. 



NAMES OF VIOLETS. 



Kindly inform me as to the names 

 of the violets enclosed; one is light 

 blue and the other dark blue. H. C. G.

 latitude of New York would be approxi- 

 mately fifty-two feet long, in Chicago ap- 

 proximately fifty-four and one-half feet 

 long and in Boston approximately fifty- 

 six feet long. L. C. C. 



The flowers when received were much 

 shriveled, but, as near as we can make 

 out, the dark variety is Governor Her- 

 rick and the lighter one Princess of 

 Wales. C. 



ALKALI WATER FOR VIOLETS. 



I should be pleased to know about the 

 effects of hard alkali water. Would it be 

 advisable to try to grow violets with the 

 use of hard water? What effects would 

 it have on violets in particular, and also 

 on carnations, roses and all other flowers 

 and vegetables. I am located in Colorado. 



M. J. C. 



Violet culture is a department of flori- 

 culture that few make any success of, 

 and especially is this so in Colorado, 

 under the influence of its mild and open 

 winters. To attempt to grow them under 

 the adverse conditions mentioned by M. J. 

 C. is certainly a problematical undertak- 

 ing. If he has any knowledge relating to 

 the properties of soil, such as its fertility, 

 consistency, firmness and porous nature, 

 and if he establishes a well drained sub- 

 soil, he is as apt to be successful as many 

 others who have had to use alkali water 



CALLAS RESTED IN FRAMES. 



Callas with us are particularly good 

 this season and we think this is due large- 

 ly to the way we dried the plants. We 

 grow both chrysanthemums and callas in 

 the same house and are therefore obliged 

 to lift the callas by the middle of May, 

 in order to get the early chrysanthe- 

 mums benched in time. It is due to this 

 that we are obliged to dry the callas out- 

 side instead of in the bench. 



Last year the plants were dried a little 

 in the bench and then lifted and laid in 

 the sun, with no soil on the roots. The 

 result was that a great quantity of the 

 bulbs rotted, and we think this was di- 

 rectly due to the rapidity with which the 

 plants dried. 



This season we thought we would try 

 a different plan. When the time came 

 to lift them, we left a 5-inch square of 

 soil on each plant, and transferred them 

 from the house to a coldframe. The 

 plants were placed quite close together, 

 soil was thrown over the bulbs and they 

 were then left to dry. About September 

 1 they were potted up. so as to keep 

 them growing until the early chrysan- 

 themums were gone. The plants have 

 been in the bench nearly a month now, 

 and are growing vigorously and flowering 

 freely. 



We are much pleased with our new 

 plan, as we did not lose a single bulb. 



A quantity of callas were planted in 

 the field for the cut blooms, but this 

 was not a success, as the plants did not 

 receive enough water. This plan has 

 its advantages, however, to any person

in their culture. I would not recommend 

 the culture of roses or carnations when 

 water has to be used that is strongly im- 

 pregnated with alkali. J, B. 



LENGTH OF SHADOW.

Anadarko, Okla. — One of the many 

 things which the Bath Addition has a 

 right to be proud of is Mr. Ernest's new 

 greenhouse, which is already stocked with 

 carnations and other plants.
