are greater lovers of light than these. Shading 

 should only be used whilst the plants are in 

 flower. They require air in abundance at all 

 times of the year, a confined atmosphere being 

 most injurious to them, especially during active 

 growth. Both side and top ventilators shoul< 

 be freely used, at the same time avoiding strong 

 rushes of air or cold winds. Except in severely 

 cold weather, the ventilators should never be 

 closed. Heaths are liable to attacks of mildew, 

 usually an indication of too close an atmosphere. 

 It should be cured by dusting the parts affected 

 with flowers of sulphur, and affording more air. 

 They dislike fire-heat; they will bear anything 

 short of actual frost, although it is not advisable 

 to subject them for long to a temperature lower 

 than from 36° to 40° during the winter. Fire- 

 heat should therefore never be used in the 

 Heath-house unless there is actual frost, or in 

 very damp winter weather, when it may some- 

 times be advisable to turn a little on early in 

 the day to dry the air. 



Plants in 5-inch pots and upwards may be 

 placed in the open air from June until there is 

 danger of frost. They grow freely during the 

 summer, and are much healthier in every way 

 when placed outside than when kept under glass.
