 so as to have the buds show six weeks or so before Easter. Potbound 

 plants properly treated in Fall and started slowly can, toward the

 them. If they show color weeks before Easter, gradually lower 

 the temperature so as to harden them off before they are sold.

 so you can water during a dry season without causing yellow foUage 

 as a result of sour soil. All Hydrangeas like moisture, but good

 will make good growth and if lifted and potted up by the middle of 

 September, brought into a frame, shaded a little and carefully 

 watered, with a fight spraying during the noon hours on hot days, 

 they will keep on growing and become re-established in the pots

Fig. 185.-^Hydhangea arborescens is not only a desirable outdoor flowering 

 shrub but a valuable florists' cut flower as well. Plants cut back in early Spring 

 will bloom fully a month ahead of H. paniculatagrandiflora. Plaee stems in water in 

 a cool place for twelve hours after picking. For best results divide field plants 

 every second or third year
