ing the plants for insects. Remove the small shoots 
where the heads are too much crowded, leaving the 
strong and vigorous shoots which are growing in a 
proper direction. By attending carefully to this 
point, additional strength is given to the plants, and 
the size and quality of the blooms are much 
improved, besides which the necessity of “ thinning” 
at the time of pruning is lessened. Fumigate plants 
in greenhouses and frames to keep down green-fly, 
and where mildew appears apply flour of sulphur. 
If this proves ineffectual, try Fowler’s Insecticide, 
using from two to two and a half ounces to the 
gallon; let the plant be syringed or otherwise well 
wetted with the mixture, and in a few hours after- 
wards syringe the plants over with clear water. 
Where the least sign of insect is observed upon the 
trees against walls, syringe frequently at night or 
morning, In favourable situations, towards the end 
of the month, many of the wall plants will be gay 
with flowers. Remove all suckers from the wild 
stock as they appear. 
June.—The directions given last month for the 
destruction of insects must be strictly attended to 
throughout the present month. The neglect of 
these precautions for only a few days may lead to 
the injury of many of the finest blooms. See 
that each plant is properly disbudded as previously 
directed ; also tie out the shoots of the compact and 
upright-growing varieties, where they are too much 
crowded. Where large blooms are desired, a few of 
the smaller buds should be thinned out with a pair 
of sharp-pointed scissors. Tie standard plants
