216 PRACTICAL LANDSCAPE GARDENING 



in very light soils. A good loam, well enriched with cow manure, 

 will produce splendid flowers. 



PLANTING AND CARE 



Fall or very earlv Spring is the best planting season for dormant 

 plants. If plants started in pots are secured they may be set any 

 time after May first. The plants should receive frequent cultiva- 

 tion during the Summer. An abundance of water will help greatly 

 in getting best results, so that, if possible, water should be piped 

 to the Rose garden for convenience. Frequent spraying of the 

 foliage with water is an aid in keeping insect pests in control. Spray- 

 ing should be done in the morning, so that the foliage will be dry 

 bj' night. 



If the plants are robust and healthy, the result of favorable condi- 

 tions, insect pests are not a serious menace. 



Green fly and aphis are most prevalent. These are easily 

 controlled by spraying with tobacco water. Leaf eating insects 

 may be kept under control by occasional sprayings with arsenate of 

 lead, eight oimces to five gallons of water, applied to the under side 

 of the foliage. For mildew apply sulphate of potassium, one-half 

 ounce to one gallon of water. 



The proper pruning of the plants will depend largely on the 

 type. The two principal types to be met in gardens are the so-called 

 hybrid tea or everblooming Roses, and the hybrid perpetuals or 

 June Roses. 



Hybrid tea Roses should be cut back severely; the strong shoots 

 should be cut to within twelve inches of the ground and the weak 

 shoots removed entirely. 



Hybrid perpetuals or June Roses are much stronger growing. 

 To insure the best individual blooms the strong shoots should be 

 cut back within a foot of the base. A less severe pruning will suf- 

 fice where quantity of bloom is desired. 



All pruning should be done very early in the Spring. 



Roses may be successfully protected from severe Winters by 

 a mounding of soil around the base. The entire bed should have a 

 light mulching with coarse manure or straw. Too heavy a mulch 

 is dangerous, as it induces growth to start too early in the Spring. 



-VARIETIES 



As before stated, the two types of Roses most generally used in the 

 Rose garden are the hybrid tea Roses and the hybrid perpetual Roses.
