in south or west windows were shaded by lace curtains, except during 

 mid-winter. This plant cannot stand full sun in late spring or early sum- 

 mer unless very careful attention is given to watering.

Watering 



Almost all growers reported watering daily, or every other day, 

 signifying that the browallia has a rather high water requirement. Plants 

 growing in glazed containers required slightly fewer waterings. 



Temperature 



This browallia was able to stand night temperatures up to 70° F, pro- 

 vided it received plenty of sunshine. In two instances where the tem- 

 perature was 70° F or above at night, and with poor light available to 

 the plants in daytime, they failed completely. Temperature plays an 

 important part in the control of thrips, also. Thrips damage was much 

 more severe on plants grown at night temperatures at 65° - 70°F or 

 above. 



Feeding 



Eight growers fed their plants regularly at two-week to three-week 

 intervals after the plants were well started. Plants that were fed re- 

 sponded favorably, even though they were growing in a fertile soil mix- 

 ture from the start. This plant is quite similar to other flowering plants 

 in that regular feeding produces better growth and more flowers. 



bisect control measures 



Fully 60 per cent of the plants on trial were troubled with insects at 

 some time or another during the period in which they were in the homes. 

 Seven growers practiced some sort of insect control measure, either reg- 

 ular washing or spraying with insecticides. Regular washing or syring- 

 ing is sufficient to rid plants of either thrips or aphids if the job is done 

 carefully. It was rather interesting to note that plants grown at cooler
