grow in the cool parts of the year. Therefore, when grown in 
hotbeds, low temperatures should be the rule. A temperature of 
60° to 65° Fahrenheit during the day and 45° to 55° Fahrenheit at 
night is about right. 
Winter Radishes .—The winter varieties are comparatively lit¬ 
tle grown in this country. The seed may be planted in July or 
early September and cultivated until the approach of severe 
weather. Then they are taken up and placed in sandy soil in the 
cellar or put in pits in the field the same as turnips. In this way, 
they will keep in as good condition as turnips. 
Varieties .—Varieties of radishes are numerous and the taste 
of the gardener as to color and shape should determine the kinds 
grown. Scarlet Button, Scarlet Globe, Scarlet Turnip White Tip, 
Long Scarlet Short Top, French Breakfast, White Olive Shaped, 
and White Icicle are all good. 
RHUBARB 
Rhubarb, or pie plant, is found in almost every garden. It is 
grown for its thick leaf stalks which are used in making pies and 
sauce. The stalks, are also cut in cubes and canned for use as oc¬ 
casion requires. Rhubarb does best in northern climates. 
Good strong one-year-old roots are the kind usually used for 
planting out permanent plantations. Such roots may be obtained 
from seedsmen or they may be grown by planting the seed. The 
latter method is cheaper, but requires one year longer. 
When ready to plant, rows are laid out 4 or 5 feet apart and 
the plants are set rather deeply, 2 or 3 feet apart in the row. The 
crowns of the plants are covered 2 or 3 inches deep with soil. The 
plants should be set deep enough so after covering there is a slight 
depression over the crowns. The roots are set out early in the 
spring. 
The crop should be carefully cultivated and liberally fertil¬ 
ized until it reaches bearing age. This is one or two years after 
the plants are set. It is better to wait until the plantation is two 
years old, as the roots will be stronger and better able to with¬ 
stand the removal of the leaves. 
After the plants reach bearing size, cultivation is usually de¬ 
layed until after the harvest period in the spring. Then a heavy 
dressing of stable manure should be put on and cultivation given 
throughout the remainder of the growing period. Seed stalks must 
not be allowed to mature, as they are a heavy drain on the vitality 
of the plants. 
Varieties .—Victoria and Linnaeus.
