SPEAYINQ FOB TOMATO BLIGHT. 



I am troubled with tomato blight. 

 Will you kindly advise me when to 

 hegin spraying, how often to spray and 

 vhen to stop? Will six pounds of 

 , opper sulphate, four pounds of lime and 

 lifty gallons of water be the proper 

 uroportions for spraying? If not please 

 ■ ive me the correct formula. 



J. M. J. 



The time to commence spraying toma 

 ioes is when they are in the seed bed, 

 Ijefore they become infected. If you 

 are troubled with the blight in your 

 section every year, it is important to 

 begin early and keep it up until late in 

 the season, at regular and frequent in- 

 tervals, probably about two weeks 

 iipart. 



I like a 5-5-50 formula better than 

 a 6-4-50 one for tomatoes. Try to use 



Three and five year old Aspara(;uH 

 roots for Immediate planting. Also 

 natural peach pits, sprouting. 



I am the only party bandllntr these large lootn. 

 The peach gprouta are Just ready to set out.

These new houses are heated by the 

 new Kroeschell hot water system 'of 

 heating and a No. 15 Kroeschell boiler, 

 which has a capacity of 50,000 square 

 feet of glass at 60 degrees at 15 de- 

 grees below zero. For the piping sys- 

 tem 4-inch threaded boiler tubes are 

 used. Each return line is controlled by 

 a small gate valve. The first boiler Mr. 

 Yonker installed was placed in a deep 

 pit. With the present system the boiler 

 may be set on the same level as the 

 greenhouse walks and the No. 15 boiler 

 is in a "pit" the floor of which is 

 twenty-four inches below the level of 

 the greenhouse beds. The old boiler pit 

 was partially filled in and now can be 

 used for growing either mushrooms or 

 asparagus.

the spray mixture the day it is mixed, 

 as it loses strength if held over. The 



• (uickest and best way to mix it is to 

 "lump the copper sulphate into five gal- 

 lons or less of boiling water and stir 

 it hard for a few minutes, and again 

 in about fifteen minutes, instead of 

 waiting all day for it to dissolve in 



• old water. Slake your lime in another 

 l)ucket. Do not let the lime burn 

 'Iry and do not drown it with water; 

 j,'ive it a little water every few minutes 

 until slaked under high temperature. 

 Then pour both into the barrel of water 

 and mix thoroughly. Stir often while 

 using it. H. G. 



YONKER 'S VEGETABLE BANOE. 



Twelve years ago E. Yonker, Grand 

 Rapids, Mich., built a small greenhouse 

 for growing vegetables. In those days 

 the greenhouses were of low construc- 

 tion and a house twenty feet wide was 

 considered a big one. Mr. Yonker de 

 voted the house to leaf lettuce. Grand 

 Rapids variety; radishes and parsley, 

 and the products were sold to the gro- 

 cers of Grand Kapids. The business for 

 the first season was encouraging and 

 the following year several additional 

 houses were built. 



The business has grown from its small 

 beginning until today Mr. Yonker has 

 one of the most up-to-date ranges of 

 vegetable houses in the state of Michi- 

 gan. The new houses erected last sea 

 son are Garland iron frame, each 

 .34x275. The eaves or gutters are eleven 

 feet high. There are no posts; the roof 

 is supported by truss construction. This 

 permits placing the heating pipes six 

 feet or more above the beds and per 

 mits working the soil by horse. 



The greenhouses are supplied with an 

 overhead sprinkling system, and each 

 house, 275 feet in length, can be wa- 

 tered from one point. One illustration 

 shows one of the large new greenhouses 

 in full crop with Grand Rapids lettuce. 

 Many of the plants weigh nearly a 

 pound. The pictures were taken Janu- 

 ary 10, 1912, and as soon as this crop 

 was cut, new lettuce plants were 

 planted immediately, so as not to lose 

 a day's time. The cucumber plants for 

 early spring forcing are already in 

 pots and will be planted in the beds 

 just as soon as the last crop of lettuce 

 is cut. 



In building a greenhouse two impor- 

 tant points are a good watering system 

 and a high smokestack. In the illus-

tration showing an outdoor view of the 

 new range of Mr. Yonker the large 

 boiler and packing shed, high water 

 tank and smokestack will be noted. The 

 packing shed is equipped with every 

 labor-saving device. The shed is large 

 enough to load the large market wag- 

 ons indoors. The packing shed is illu- 

 minated by a gasoline lighting system 

 and of course also is provided with tele- 

 phones. In one corner of the building 

 there is the neatly equipped private 

 office of Mr. Yonker. 



SUPPOETINQ CUCUMBERS. 



Three beds in my greenhouse are 

 filled with lettuce about six inches high, 

 with cucumbers, showing the second 

 leaf, through the center of each bed. 

 Will you please give instructions as to 

 the best method for supporting the cu- 

 cumbers, and some hints as to their 

 future treatment? .1. V. S. 



The vines may be trained on wires 

 running the length of the house, one 

 above the other, keeping them at least 

 a foot away from the glass and follow- 

 ing up to the ridge. As soon as the let- 

 tuce is cut, the cukes will need all the 

 beds for root room. Keep the tempera- 

 ture at 65 to 68 degrees at night and 

 about S.") degrees on bright davs.
