August at a new location remote from the older houses, 

 where we could find no trace of this trouble. Possibly, by 

 using movable greenhouses we could travel ahead of it. 



The " green worm " never caused us much trouble 

 until 1912, when it seemed to come in droves. Poisoning 

 was tried with different compounds, but very few worms 

 seemed to be killed by this means, and we had to resort to 

 hand picking. 



Bud dropping is caused by too sudden changes from 

 long continued warm weather to dark, cloudy weather, or 

 the reverse, or from too high an artificial temperature, 

 followed by a sudden drop. 



As to temperature — during Midwinter we run a night 

 temperature of 50 deg.; during cloudy weather 55 deg., 

 and 60 to 65 deg. during bright, clear weather. Toward 

 Spring we drop to 45 to 47 deg. at night and the same day 

 temperature as during Midwinter. 



Sweet Peas require constant attention after the vines 

 are tall enough for support, to see that they are kept growing 

 erect; in fact, from that time on during the blooming period 

 more labor is required than for any other greenhouse crop, 

 that is, if you wish to handle the stock carefully and for profit. 



NEW YORK AND EASTERN STATES 



As it was from New York and New Jersey that the 

 first early flowering Peas were heard of, and as Winter 

 Sweet Peas have been sold in New York and Eastern mar- 

 kets for upward of 20 years, it will be understood that in 

 the intervening period the development in the flower and 

 its culture have been as noticeable here as in any other 

 section. Probably more Sweet Peas are grown in the 

 region under note than in any other. Zvolanek, Sim,
