280 ANNUAL, REPORT OF THE Off. Doc. 



should be pricked off as soon as large enough to handle, again using 

 pans or small boxes; this time using two parts well decomposed 

 sod and one part leaf mould and a little sand. After a day or two 

 of careful shading, they should be gradually given air and a posi- 

 tion selected as near to the glass as possible. When strong enough 

 they may be potted into two and a half inch pots and placed in a 

 frame outside, if possible, with the sashes elevated sulticiently so 

 that a free circulation of air may be assured at all times when the 

 weather is favorable. In the outside frame they may remain until 

 cool nights set in, by which time they should be large enough to 

 be repotted into three-inch or four-inch pots, according to the 

 strength of the plants. By following the method recommended, 

 some of the very largest will become sufficiently large to occupy a 

 seven or an eight-inch pot to advantage. 



The temperature in the winter months for these cool greenhouse 

 plants should, whenever possible, be kept down to from 45 to 50 

 degrees in daytime, and at night from 42 to 45 degrees. 



The greatest care must be exercised in the watering, especially in 

 the winter-time. They sutTer a great deal if allowed to become too 

 dry, and one overdose of water will almost kill them. 



Its greatest enemy in the insect line is the green fly. To overcome 

 this trouble, tobacco stems must be liberally placed between the 

 pots. 



This is the method I used last year and had very good results. I 

 had in the months of April and May plants full of bloom, growing 

 in six-inch pots two feet across, and they were grown in a natural 

 way without training, w^hich surprised many of my gardener friends 

 who called to see them. In the collection of over three hundred 

 plants, it was hard to find two alike, so varied were they in their 

 shadings and markings. Among them were some very nearly clear 

 white; one was a pure canary-yellow, and again one was a canary- 

 yellow with large spots very nearly black. 



I hope, with the brief cultural directions given, that my fellow 

 gardeners will take them in hand and make an effort to grow them, 

 for nothing, in my opinion, gives more pleasure than a collection of 

 well grown Hybrida Calceolarias.
