The Weekly Rorists' Review. 



Fbbbcabt 11, 1909. 



growing of cut flowers and decorative 

 plants. Several lectures are devoted to 

 window-gardening and the growing of 

 flowers in the home grounds. The course 

 is given in the second .semester and con- 

 sists of thirty-four lectures and recita- 

 tions and seventeen practicum periods of 

 two hours each. The Pennsylvania legis- 

 lature at this session will be asked to 

 appropriate about $25,000 for the erec- 

 tion of greenhouses at the State College. 

 With such a range, the college will be in 

 a position to give most complete courses 

 on all lines of floricultural work. 



B. L. Watts, professor of horticulture, 

 is in charge of the department. Prof. 

 J. P. Pillsbury is instructor in flori- 

 culture. The course in horticulture, 

 which includes floriculture, among many 

 other things, provides specially for the 

 study of the following topics: 



Plant Propagation. — A consideration 

 of the methods by which plants are prop- 

 agated; germination and testing of 

 seeds; hard and soft wood cuttings; 

 grafting, budding, propagation by divi- 

 sion and layerage. Special attention is 

 given to the methods most commonly em- 

 ployed by market gardeners, florists and 

 nurserymen. 



Greenhouse Construction. — A course 

 on the construction and heating of vari- 

 ous types of greenhouses used on private 



pounds -and hy commercial establish- 

 ments. Among the problems considered 

 are the forms of houses, materials used 

 in construction; heating by flues, hot 

 water and steam; various types of boil- 

 ers and the installation of heating plants. 



Vegetable Forcing. — A study of the 

 principles of vegetable forcing in cold- 

 frames, hotbeds and greenhouses. Some 

 of the vegetables considered are the to- 

 mato, lettuce, radish, cauliflower, aspara- 

 gus, cucumber, rhubarb and mushroom. 



Plant Breeding.. — A study of the prin- 

 ciples of plant breeding and their appli- 

 cation to the improvement of fruits, veg- 

 etables, flowers and ornamental trees, 

 shrubs and vines. 



Landscape Gardening. — The principles 

 of landscape gardening are studied and 

 applied to the planting and beautifying 

 of home grounds, school grounds, parks 

 and streete. The trees, shrubs, vines and 

 plants on the college campus are particu- 

 larly valuable in furnishing material for 

 practicum work. 



Washington, D. C. — O. A. C. Oehmler, 

 of the Gude Bros. Co., recently met with 

 a painful accident while taking down 

 a decoration. Two of his toes were 

 crushed, but he hoped that in a few 

 days he would be able to attend to his 

 duties as usual. 



STIGMONOSE AND LEAF SPOT. 



I send you two shoots of my Rose-pink 

 Enchantress. This disease started about 

 five weeks ago and spread all over the 

 house. As soon as the plants are affect- 

 ed, they grow poorly. I am afraid I 

 may lose the whole crop and shall be 

 very thankful to you if you will tell 

 me what kind of disease it is and what 

 is the remedy for it. C. T. 



Most of the light spots on or in the 

 foliage seem to be stigmonose, though 

 there seem to be some spots of the 

 common leaf spot. For the former you 

 can do but little, except to give your 

 plants a very moderate diet, careful 

 watering and abundant ventilation. Se- 

 lect your cuttings for next season's stock 

 carefully, from plants which do not show 

 this disease. In this way you may gradu- 

 ally work out of the disease. The En- 

 chantress varieties, being-ragid and suc- 

 culent growing -sorts, . are fkst getting 

 filled np with this disease, and, unless 

 the most rigid selection of cuttings is 

 practiced during the next few years, this 

 group of varieties will soon pass out of 

 cultivation. 



For the spot disease use Bordeaux 



mixture. You can buy this in soluble 

 form, to be diluted to the proper strength. 

 Apply about once each week and wash off 

 with a fresh water spray before apply- 

 ing each succeeding dose. Choose a 

 bright day for this. 



Drop a pinch of sulphur here and there 

 on the steam pipes, to keep the air pure 

 and sweet. A. F. J. B. 



LAWSON THE SECOND YEAR. 



W^ hear much about Lawson carna- 

 tions running out and are inclined to 

 share the same opinion. But before we 

 drop this grand old variety from our list 

 we want to give the trade the benefit 

 of our experience and observations of 

 this variety grown the second season 

 without replanting. 



Two years ago we had two benches 

 that looked good to us late in spring, 

 and we decided to run them over another 

 season. During June we topped all the 

 shoots that were beginning to run up to 

 bud. We kept them well fed and prop- 

 erly syringed and watered during the 

 summer, and kept the-honse as oool as 

 possible at all times. We applied a 

 thick mulch of rich compost and l?ave 

 the plants every encouragement to liake 



a good growth. The way those plants 

 bloomed last winter was a sight to see. 

 They started in a little late, about the 

 last part of October, but from then on 

 were a wealth of fine blooms on good 

 stems throughout the winter, producing 

 much more heavily than the first season. 

 Our only reason for not having some of 

 this variety the second season this win- 

 ter is that we did not plant any new 

 benches of it last year. One of our 

 ' neighbors, though, has a bench in its sec- 

 ond year this winter, which gave him the 

 same results as we got from ours last 

 winter. He topped his a little earlier in 

 the season than we did, and consequently 

 began cutting that much earlier. 



We would hesitate to recommend this 

 system of growing carnations for all vari- 

 eties, but with Lawson we unhesitatingly 

 recommend it. Care must, however, be 

 taken to give the best of treatment. As 

 soon as the spring crop is off, the plants 

 should confine all their attention to mak- 

 ing a strong growth. We shall try this 

 system with several varieties this coming 

 seesoB -in -solid beds. Our plan is to top 

 them during April and May, instead of 

 June, and thus throw the crop earlier. 

 Our previous experiment, as well as that
