Questions by our readers In Une with any of the topics presented on this page will be cordially received and promptly answered 

 by Mr. Ruzlcka. Such communications should invariably be addressed to the office of HORTICULTURE. 



Watering 



This will now become important and houses that have 

 already started should be watered with great care. This 

 is especially true where all kinds of plants have been 

 planted together. We make it a point to grade the 

 plants a little so as to get uniformity in the bench if pos- 

 sible, setting the taller plants to the back and the shorter 

 to the front. In watering a bench of mixed plants be 

 careful and give each just the amount of water they re- 

 quire. A small weak plant will want only about half as 

 much as a strong rapidly growing plant will. Another 

 thing to watch out for is not to allow the plants to become 

 too dry although they should always become fairly dry 

 before watering again. If allowed to dry out too much 

 they will become weak and spindling and will not be in 

 condition to produce the required result next winter. 



Roses growing in less than four inches of soil must be 

 carefully watched during these hot summer days. These 

 will dry out much more rapidly than plants in deeper 

 soil and should be watered accordingly. 



Red Spider 



This if allowed to go unchecked will spread very rap- 

 idly at this time of the year. Syringe the plants as of- 

 ten as is advisable, being careful not to have them dry 

 when syringing. Remember that, summer is the time to 

 clean out spider, if there is any anywhere. If a nest is 

 allowed to remain here and there plenty of trouble can 

 be expected during the fall months, when syringing can- 

 not be done as often as now. 



Roses Outside 



Killamey, Kaiserin, Radiance and other roses grow- 

 ing outside will now be in bud for their second crop and 

 should receive a good mulch of cow manure. A little 

 bone meal will also be good for them. Keep them well 

 watered and if possible spray frequently with a good 

 solution of ivory soap and water. This will keep most 

 bugs away, and should it not, then give them a little 

 paris green or arsenate of lead. We would prefer the 

 former, as arsenate of lead shows so much on the foliage. 

 Keep the plants well disbudded if you expect real nice 

 flowers from them. With a little care these plants 

 should produce almost as good roses as those grown in 

 the gi-eenhouses. If all are planted as advocated in 

 these columns some time ago, they can be handled very 

 easily and if kept well mulched will require but little 

 looking after. 



Qeaning: Up 



With most of the houses planted, it is a good idea to 

 give the place a good clean-up and thus start the new 

 season with a clean place. Scrape out well underneath 



the benches in all the planted houses and fill in all holes 

 m the walks with ashes or cinders. Where it is not too 

 expensive, sand makes a very nice covering for all earth 

 walks. Apply just enough to cover the surface nicely. 

 Many will claim that this is too rough for the hose but 

 we find aslies alone wear a hose as fast as anything. 



Hose 



This is something which costs our florists a great 

 sum of money every year.. There are a great many good 

 makes of hose on the market and with a least bit of care 

 a hose ought to last. If possible, have a hose for each 

 walk. This may seem like expense at first, but will 

 save money in tlie long run. If there is only one or 

 two hose for the house and it has to be dragged around 

 the corners, have the corners covered with some soft 

 material. A good way is to cut a piece of hose open 

 and then nail it to the corner. Instruct all help to avoid 

 kinks fomiing, which wears out a hose quicker than any- 

 thing else would. 



An Adept in Fruit Growing 



As an old fruit-grower, I have noted with consider- 

 able pleasure, from time to time, the notes on fruit cul- 

 ture under glass contributed by Mr. Geo. H. Penson 

 to Horticulture. Anyone who saw the exhibit 

 staged at Asbury Park Show by Duke's Park, where 

 Mr. A. A. MacDonald presides as superintendent and 

 Mr. Penson is the fruit-grower, will appreciate the ex- 

 cellent culture that produced such phenomenal fruits as 

 were exhibited. 



Duke's Park was awarded five firsts in the five entries 

 in the competitive section. I do not believe I ever saw 

 finer grapes staged anyAvhere. They were certainly very 

 far ahead of the grapes staged at the International Show 

 in London last month. Conceding that we have a cli- 

 mate that ripens grapes and all fruits better than that of 

 England, the fact still remains that these were mag- 

 nificent specimens. Black Hamburgh, Appley Towers, 

 Foster's Seedling and Bucklands Sweetwater, were the 

 varieties staged. Melons which were on an average of 

 nine pounds each were also remarkable for their size 

 and finish; Hero of Lockinge, Duke's Park Seedling, 

 Royal Jubilee, His Eminence, were the best. 



The peaches and nectarines also were simply marvel- 

 lous, and all fruit exhibited from this estate was a les- 

 son to the gardeners present.
