Questions by our readers In line with any of the topics present** M thU page will be cordially recelTed and promptly answered 

 by Mr. Farrell. Such communications should invariably be addressed to the office of HOETICULTUKbi. 



Bouvardias 



Nice stock oxit of 2 inch or 2i inch pots planted out 

 now will give the plants for benching in September. 

 Allow about 12 inches of room each way, making use 

 of a good mellow loam for planting. Flowers are not 

 wanted on them at this season and the shoots should be 

 kept pinched back whenever they run away and show 

 an inclination to ilower. Keep the ground well culti- 

 vated about them and if the weather becomes dry keep 

 them watered and their growth will not be checked. 

 There is no more to their culture than other plants, such 

 as roses or carnations, require and you can have them 

 in flower from October on to the last of March. These 

 flowers come in very handy during the winter. The 

 only thing they want is good rich soil and a light house, 

 where the temperature can be kept at about 60 degrees 

 during the night. 



Care of Newly Planted Chrysanthemums 



While the chrysantiiemura is considered quite easy to 

 grow, it will require good attention from now and until 

 the flowers are cut. In watering the benches it is a 

 better plan to water only just around the plants until 

 they have made new roots when the whole bed can be 

 watered. On briglit days give them a good syringing 

 getting well under the foliage. Do not allow the 

 benches to become overrun with weeds. Keep the soil 

 well cultivated between the plants which will help to 

 keep the compost sweet while heavy syringing is needed. 

 Chrysanthemums are air-loving plants so do not coddle 

 them at all, but give them all the ventilation possible. 

 Do not leave them too long without supports as the 

 syringing is very liable to knock them about. 



Cyclamen 



An important jdant that is often neglected at this 

 busy season. In the coming three months they will 

 either make good plants or be failures. Be certain that 

 they do not become potbound, or chances of their doing 

 well are mucli lessened. Cyclamen will now be ready to 

 go into 4-incli jwts and there can be no better place for 

 them between now and the end of September than cold- 

 frames, where the plants will not be kept too close to 

 the light. Tile glass should be shaded by lath coverings 

 which also keep the plants cooloi'. Keep the sashes open, 

 both top and bottom all tliis time. This is easily ar- 

 ranged by making a temjMrary wooden framework a 

 few inches high and standing the sashes on this. This al- 

 lows a current of fresh air to strike the plants con- 

 stantly. 



Outdoor Roses 



Some of our best roses always suffer more or less from 

 mildew at about this time, notably moss roses, some 

 varieties of the hybrid perpetual class and nearly all of 

 the multiflora section, of which Crimson Rambler is 

 the most striking example. However, it can be kept in 

 check to a considerable extent by a timely use of such 

 remedies as ammoniacal copper solution, grapedust and 

 powdered sulphur, in mild but frequent applications. 

 The June bug is one of the early callers and a marauder 

 that defies the common tactics of the rose grower. 

 Dustings and sprayings of deadly decoctions are of little 

 avail in its case. Gathering the bugs by hand is the best 

 way to bring about a noticeable scarcity of June bugs. 

 Roses out of doors are hardly ever troubled by red spider, 

 if well attended to, but when once infested it will be 

 found that the evil is much harder to fight in the open 

 than under glass. Syringing, forceful and often, in any 

 event a great help to roses in hot and dry weather, is the 

 remedy here as well as indoors. 



Summer Treatment of Potted Roses 



1 have found that potted roses intended for next win- 

 ter's forcing or for the plant trade in the spring, do 

 l)etter if kept constantly in the greenhouse during the 

 hottest part of summer than they would anywhere otit 

 of doors. There is no doubt that roses grown in pots 

 all summer are much easier to manage and give greater 

 satisfaction when forced the following winter than roses 

 grown in the open field and potted up in November. 

 These make a steady and most rapid growth up until 

 about the middle or end of August. By that time they 

 have undergone the last of the many shiftings from pot 

 to pot that are necessary to keep them in good shape, and 

 at a rapid headway.- When growing fast they need a 

 deal of water and a sprinkling once or twice a day. The 

 essence of advancement in any trade lies in the produc- 

 tion of a better article from year to year, not in the 

 searching for or finding of easy methods alone, especial- 

 ly not when this tends to decrease the commercial value 

 of the output. 



Sowing Late Annuals 



Now and up until the last week in this month is a 

 good time to sow a number of annuals for cutting. These 

 are all suitable to sow : Clarkias, candytufts, calendulas, 

 coreop.sis. larkspurs, lupines, Shirley iiopiiies, etc. The 

 only trouble is to get the seed to come up good, on ac- 

 count of the dry weather, so it is well to sow where they 

 can be handv for water. Use the hoe freely between the
