The Weekly Florists' Review- 



August 16, 1906. 



BLACK SPOT. 



The season is now approaching when 

 Beauties are liable to be attacked by 

 black spot, and every grower of these 

 who is alive to his best interests should 

 be on the lookout for the trouble and be 

 ' ready to stamp it out as soon as it 

 makes its appearance. 



Houses which are situated on low, 

 marshy ground, or where they are too 

 much sheltered, and where naturally 'the 

 foliage is soft, will be the first to suffer. 

 Care should be taken to keep the atmos- 

 phere of the house in as dry a condition 

 as is consistent with the health of the 

 plants. Avoid all sudden fluctuations of 

 temperature, and be sure to have the 

 foliage dry by sundown. 



To prevent and hold this fungus in 

 check, a spraying of carbonate of cop- 

 per is recommended, using three ounces 

 of the carbonate and one quart of am- 

 monia to fifty gallons of water; apply 

 once a T^eek. 



Cleanliness and care play an impor- 

 tant part in preventing and checking the 

 spread of this trouble. 



Those leaves at the base of the stem 

 which touch the soil should be picked 

 off, as it is there the trouble usually 

 begins. All ripe, spotted and decaying 

 leaves should be carefully picked off 

 every day and destroyed. If this treat- 

 ment is persisted in for a few weeks, 

 and special care taken not to overwater 

 so as to check root action, if the tem- 

 perature is kept right and intelligent 

 ventilation practiced, this disease need 

 give us little trouble. Bibes. 



TROUBLE WITH NEMATODES. 



I have greenhouses in which I have 

 raised tomatoes for several years; the 

 plants are in the ground, not on benches. 

 They have become infested with nema- 

 todes. Being told that each species of 

 plant life has its own kind of nema- 

 todes, which would trouble nothing else, 

 I put cucumbers, beans and some carna- 

 tions in the same house. The first two 

 became infested, but so far the carna- 

 tions are untouched. I want to put some 

 roses in also. Will they become in- 

 fested? A. L. H. 



That there are innumerable species of 

 nematodes, both parasitic and free-liv- 

 ing, is certain, but that there is a sepa- 

 rate species for each plant or animal 

 appears to be a far-fetched theory, and 

 quite beyond my powers of resea'^h. 



The free-living forms are found every- 

 where, in salt water and fresh, in damp 

 earth, moss, and among decaying sub- 



stances. They are always minute in size 

 and, like many other lower forms of life, 

 are capable of retaining their vitality 

 for a lufig period, even when dried, 

 which accounts for their wide distribu- 

 tion. 



If the soil is good and properly en- 

 riched, and the rose plants are of good 

 constitution and properly handled after 

 benching, there is little danger to be ap- 

 prehended from eel worms.

S. S. PENNOCK, MEEHAN CO. 



The most important combination ever 

 made in the wholesale commission busi- 

 ness of Philadelphia was effected this 

 week, when it was announced that Sam- 

 uel S. Pennock and Charles E. Meehan, 

 the latter of the Philadelphia Wholesale 

 Flower Market, had agreed to form a 

 partnership to be incorporated under the 

 name of S. S. Pennock, Meehan Co., with 

 a capital of $60,000. 



This news was the more surprising be- 

 cause both houses stood among the lead- 

 ers in the wholesale business, and it was 

 believed the competition between them 

 was very keen. It is thought that the 

 fact that both Mr. Pennock and Mr. 

 Meehan have summer cottages at Ocean 

 City, N. J., may have led to confidential 

 chats during their daily trip from and to 

 the shore, enabling them to reach an 

 agreement that would not have been pos- 

 sible under ordinary circumstances. 



The new firm will carry on business 

 at 1608-1618 Ludlow street, Mr. Pen- 

 nock's present quarters, and they be- 

 lieve that they will be in a better posi- 

 tion than ever before to handle and dii- 

 tribute cut flowers and supplies.

roses in any worn-out soil, however rich 

 the fertilizer may be, as they rarely do 

 well in soil which has been in use in 

 greenhouses until it has been exposed to 

 the open air a sufficient length of time 

 to recuperate. Try fresh, virgin soil, 

 with the addition of one-fifth of its bulk 

 of decomposed cow manure, thoroughly 

 incorporated, and give your roses a 

 chance. Ribes. 



Samuel S. Pennock started in business 

 in 1888, with his brother, Charles E. 

 Pennock, who was the pioneer wholesale 

 florist of Philadelphia. At that time 

 the business was carried on in the base- 

 ment of a plumber's shop at Sixteenth 

 and Sansom streets, and it was of mod- 

 est size. Mr. Pennock threw his whole 

 energy into his work and gradually de- 

 veloped it. taking entire charge after
