It will be necessary to give the 

 sweet peas a little heat from now on, 

 but at the same time full ventilation 

 must not be overlooked. Fall peas like 

 an abundance of fresh air, yet they 

 are impatient of draughts, and many 

 a case of mildew can be traced to such 

 a cause. Let the night temperature 

 down to about 50 degrees for flower- 

 ing peas, and later on it will be better 

 to have it two degrees lower. Just at 

 present the demand for sweet peas is 

 not great. Indeed all other flowers 

 are eclipsed for the time being by the 

 ubiquitous chrysanthemum. Yet there 

 is a certain call for them, and the de- 

 mand will grow rapidly as the season 

 advances. Watering is one of the 

 things which must be done carefully 

 and syringing will be necessary to 

 keep down the red spider. It should 

 be done early in the morning, however. 



Apparently the Bouvardia is regain- 

 ing much of its old time favor. In any 

 event It is being shown very generally 

 which is an indication that it is in de- 

 mand as a cut flower. It has long 

 been a question whether Bouvardias 

 pay and the answer oftentimes de- 

 pends upon one's particular locality. 

 Growers must remember that this is 

 a tropical plant and must have a low 

 temperature at no time. They suffer 

 from attacks of red spider and the 

 mealy bug, but these pests are readily- 

 kept away by proper use of the hose. 

 Fumigation is required for the red fly 

 but the fumigation should be light, 

 because Bouvardias are very easily 

 burned, particularly at this season. 

 Bringing as good price as they do in 

 many markets, the Bouvardia is well 

 worth the attention required to grow 

 it. 



A good night temperature for tarna- 

 tions at this season is from 48 to 52. 

 In the daytime it may go to 60 if the 

 weather is cloudy or 72 when the sun 

 shines. Ambitious greenhouse men 

 are sometimes tempted to give a little 

 more heat with the hope of getting a 

 few more flowers, but in the end this 

 Is poor policy, for the plants suffer 

 from forcing. With the plants full of 

 buds, a little top dressing of the soil 

 will be an advantage. The beds often 

 dry out unevenly. Watch for the dry 

 places and apply water at once. 



If you want to propagate some Cro- 

 tons you can do it in the same way as 

 rubber plants. Choose good shoots for 

 the incisions and use toothpicks to

keep them open. You don't have to 

 use a big wad of sphagnum moss 

 around the wound, but the moss must 

 be kept constantly wet. In a month 

 and perhaps less the moss will be 

 filled with the roots at which time the 

 tops can be cut off and potted up. 

 This is a very good time of year to do 

 this work. After the plants are 

 started, keep them well watered, pro- 

 tect from sunshine and spray occasion- 

 ally. Use soil, leaf mold and sand in 

 equal parts for your potting soil. Just 

 one other point, — you will need high 

 temperature for best results when 

 rooting Crotons. 



Violets are flowers which demand a 

 great amount of air, which means that 

 the violet houses must not lack for 

 ventilation. The proper use of air and 

 water make the difference between 

 success and failure in growing violets. 

 While they like moisture at the roots, 

 they rebel at a soil which is kept 

 water soaked. Do not make your over- 

 head spraying too heavy, and always 

 do the work in the morning. Of course 

 you will choose only sunny clays for a 

 general wetting down of the walks. 

 Constant vigilance is certainly the 

 price of success in growing violets, 

 and it will be necessary to keep a 

 close watch for insects or for black 

 spots on the leaves. 



It is easy to make mistakes in the 

 use of water for many plants, and this 

 is one place where experience counts 

 very much. It is worth while to pay 

 the price of good labor rather than to 

 have damage done by green hands. 

 Mignonette is one of the plants very' 

 easily injured by over-watering, 

 whether in pots or on the benches. 

 Too much water is also bad for Peper- 

 onias. They suffer much from being 



kept too wet. Remember, by the way, 

 that while Peperonias need shade in 

 the summer, they can stand full sun- 

 shine at this season. While lilies like 

 plenty of water, they can easily be 

 given too much until they have filled 

 their pots with roots. As a matter of 

 fact, this applies to other bulbs, par- 

 ticularly to callas. Increase the water 

 supply and the root and top growth 

 becomes extended. • 



Keep the Stevias cool but at the 

 same time have them on a light bench. 

 It is only by keeping them cool and 

 yet light that you will have robust, 

 sturdy plants with fine spikes for the 

 holidays.
