Keeping Evergreens 
Methods Recommended by The Wisconsin 
Department of Agriculture and Markets. 
With the advent of hot dry summer 
weather evergreens should be given 
plenty of water and carefully guarded 
against red spider attack. This pest is 
a very small mite, barely visible. If al- 
lowed to become numerous on ever- 
greens that mite will, through its habit 
of sucking sap from the foliage, cause 
them to lose their characteristic colors 
and assume a “rusty” appearance. Red 
spider can readily be controlled by the 
employment of one of the following 
methods: 

1. Syringe the foliage with water under pressure 
from garden hose or power sprayer, taking 
particular pains to secure a forceful spray 
applied from underneath the foliage. 
2. Spraying with a glue spray consisting of 
Y, lb. of a cheap grade of ground bone glue 
in 5 gals. of water. (Dissolve the glue first 
in a small amount of boiling water.) 
3. Dust with sulphur liberally on a warm day, 
using a superfine commercial brand of dust- 
ing sulphur. 
Follow directions. If used as recommended 
no injury will result from any of these treat- 
ments. Avoid spraying an evergreen in the 
middle of the day as water alone will sometimes 
result in injury by scalding at such times. Re- 
peat treatment six days after first application to 
kiH young spiders escaping in egg stage and re- 
member that applications should be made as 
often as necessary because of continual rein- 
festations.

Follow directions as outlined in picture 
above. If ball of earth appears hard and dry 
upon arrival soak it in a tub of water before 
planting. Leave saucer around base of tree 
so that drainage will be towards tree. Do 
not put fresh manure in hole so it comes in 
contact with the roots. Use well-rotted ma- 
nure and spread it on the ground after tree 
is planted and hole filled up. Keep ground 
well cultivated or mulched. When watering 
see that ground is soaked to a depth of 12 



How to Prune 
Evergreens 
Evergreens are pruned for the following reasons: 
To keep tree within certain limits of size. 
To shape the tree into some special form. 
To invigorate a weak tree. 
In order to keep a planting of evergreens around 
a small home neat and attractive for the greatest 
number of years, requires that their size be kept 
within certain bounds. The first consideration, of 
course, is to choose trees which are more nearly 
suited by natural growth to the planting being done; 
and then to keep them in a thrifty, vigorous, and 
attractive form by pruning. 
The ideal time for pruning evergreens is in late 
spring or early summer, although they can be 
trimmed any time from late March until October. 
PRUNING JUNIPERS, ARBOR-VITAE, YEWS 
AND HEMLOCKS 
These evergreens can be trimmed severely with 
pruning or hedge shears and kept to a certain size. 
Naturally, it is better practice to prune regularly 
once or twice a season, rather than to neglect prun- 
ing for several years and then expect to bring the 
trees back into form all at once. Again trim less 
severely the first few years after planting, than in 
later years, after the trees have reached the ideal 
size. Don’t hesitate to cut off the top of the tree 
when it has reached the desired height. 
PRUNING PINES AND SPRUCES 
These are best pruned in early summer when the 
new yellowish green stem is developing but before 
the needles have started to grow out from these 
stems. If this ideal pruning time has been delayed, 
it can still be done when the needles are growing 
but before they are full grown. Pines are best 
pruned with a knife or small one-hand pruning 
shears, by cutting off a given amount of this new 
growth each year. 
When the trees are small and newly planted, 
merely cut back some of the longer branches to 
shape and form the trees. When the trees get to 
be of proper size, cut off nearly all of this new 
growth, including the top of the tree. In this way,
