ROSES 79 



better second growth is secured, and it does no harm to next season's 

 blossoming. It is a great strain upon a plant to allow it to seed. As 

 the flowers die off, cut back the growth at once, instead of allowing the 

 seed-pods that appear at the base of the flower to develop. The plants 

 should also have some liquid manure about once a week. 



Pests, Insect and otherwise. Caterpillars and green-fly are the 

 worst insect pests. There is nothing better than hand-picking for the 

 former. When two leaves are stuck together, or rolled up, a fat maggot 

 will be found. Pinch the leaf, and this will settle the marauder. Con- 

 stant watching is necessary. Do not let two days go by without looking 

 over all the plants. Many a flower is injured through neglect of this 

 precaution. When pruning is carried out as directed, and the plants 

 relieved of much old wood, the eggs of these caterpillars will depart 

 also. Green-fly will not trouble those who keep their Roses thoroughly 

 healthy. Good syringings with cold water dislodge many, and it is a 



food plan to dip the ends of the young shoot when covered with green- 

 y into a vessel of strong tobacco water or quassia chips solution. 



A good recipe for quassia chips solution is as follows : Take four 

 ounces of quassia chips, steep them in water for a few hours, then 

 simmer from twelve to twenty-four hours in a gallon of water, and add 

 three ounces of good soft soap. When dissolved, add water to make up 

 two and a half gallons. Green-fly upon Roses under glass can be readily 

 exterminated by fumigating. M'DougalPs tobacco sheets are the simplest 

 remedy. One or more, according to cubic measurement, are hung in the 

 house, and set alight. They gradually consume, and not a fly will be 

 found the next day. Richards' XL All is too well known to need de- 

 scription ; it is an excellent fumigant. 



Red spider is often very prevalent on Roses under glass. Want of 

 syringing and too dry an atmosphere cause it. The leaves turn yellow 

 and drop off. With a magnifying glass the pests may be seen running 

 about on the under side of the leaf. The same fumigation will check 

 them, but syringing well the under side of the leaves is the best remedy. 

 Mildew is a troublesome fungus. It inflicts considerable injury by 

 choking the breathing pores of the foliage, and consequently growth is 

 hindered (see illustration). When a plant is badly attacked, the latter has 

 the appearance of being dusted with flour. It makes its appearance under 

 the leaf as well as on the surface. A thoroughly good dredging with 

 black sulphur, underneath as well as on the surface of the leaf, will check 

 its ravages. Put some sulphur in a piece of cheese-cloth made into a 

 bag, and thoroughly dust the foliage with it. After remaining on for 

 two days, syringe off and give another dredging if needful ; this should 

 be done on a quiet evening, when the foliage is slightly damp. It is a 

 mistake to wait until the plants are badly attacked, but as soon as a 

 few spots appear, press them with the thumb and finger, previously 

 dusting or dipping the thumb and finger into some sulphur. Mildew 

 is the result of a check of some kind. Out of doors one cannot quite 

 avoid it, but never let anything, if possible, check the young roots, such 

 as strong liquid manure. Indoors one is troubled most with mildew.
