‘Cultural Instruction for Dingee 
Winter Protection 
The protection needed varies ac- 
cording to the climate and varieties 
of roses. After a few hard frosts 
have stopped the growth throw up 
a mound of earth about a foot high 
around the plant. In cold sections 
after the ground has frozen put 
straw or other coarse litter in be- 
tween the mounds built up around 
each plant. The tops of the bushes 
sticking out above mounds may be 
covered with evergreen boughs. 
Do not remove this covering until 
spring has come to stay and re- 
move gradually. 
Pruning 
As soon as the winter covering is removed, first 
sut away all weak stems and leave three or four of 
she strongest. Prune these down to at least six inches 
aigh with the Hybrid Teas. Hybrid Perpetuals or 
che June Roses do not need as close pruning. Bushes 
chat are 2 to 4 feet in height should be cut back 
about 1-2 or 2-3 of their growth. The Polyantha and 
Baby Ramblers need just the tips cut. Climbing 
Roses should be pruned after blooming, cutting out 
ill shoots and allow the new ones to develop and to 
rain. Keep all weak lower side stems cut away 
shroughout the season. When several buds appear 
on one stem the smaller buds may be pinched off to 
make one fine large rose. 
Selection of Roses Important 
One of the most difficult problems that presents 
tself to the amateur about to start a rose garden, 
| the very first that he has to solve, the selection 
of the best varieties of roses for the purpose for 
which he intends them. The success he will have 
_with his roses depends very largely on intelligent 
selection of adaptable varieties. The matter of selec- 
sion is one that should be left to the purchaser. 
Many of our customers grow 100 or more different 
_\cinds and they find exquisite beauty in each. At the 
nodest price asked for them any one can enjoy 
nany sorts. 
| Hybrid Teas 
| The most popular type of rose in this country to- 
lay is the Hybrid Tea. Hardy in almost all sections 
(of this country and Canada. Buds handsome and 
isually long pointed, opening into magnificent 
jlooms, varying from semi-double to full double. 
?roduced usually on long stiff stems and singly. 
| *ragrance usually predominates, more in some than 
others. Foliage heavy and seems to resist mildew 
| md black spot. Blooms almost as freely as the Teas. 
Dwarf Baby Ramblers 
These are a type of Polyantha Rose but more 
| twarf in habit, 12 to 18 inches. Hardy and suitable 
or beds or borders along walks, etc. Small blooms 
ao immense clusters. Always blooming. Those offered 
-n catalog are the standard sorts, all good. 
A Rose Hedge made of Climbing Roses 
Climbing or Rambling Roses 
The Climbers are not so susceptible to mildew and 
disease as the Ramblers, therefore much to be pre- 
ferred. Some of the Hardy Climbers resemble the 
Ramblers so closely that any one wanting them will 
find a great improvement in such Climbers as Ex- 
celsa, Tausendschon and Aunt Harriet. 
Climbing Roses should all have some support such 
as a pergola or arch. A wire fence, where convenient, 
may be utilized with splendid effect. They also make 
a good hedge. 
For pillars, roses like Paul’s Scarlet, Birdie Blye, 
Dr. Huey, Mary Lovett, Climbing American Beauty 
are good. They may also be used as individual speci- 
mens by pruning to a shape and size desired.
