Maintenance Service 
@ We specialize in evergreen maintenance. All] sum- 
mer long, our entire crew of men is engaged in spraying 
and shearing evergreens. All evergreens should be 
trimmed every year by experienced nurserymen, 
e <A good many new insect pests are showing up and 
a considerable number have been with us in the Detroit 
area for a long time, and thru neglect, many people are 
loosing valuable evergreens, because they do not recognize 
insect infestation in their evergreens until it is too late. 
The old adage “A stitch in time saves nine” was never 
truer than when applied to evergreen spraying. I will 
give you a list of just a few insects infesting evergreens 
in the Detroit area. 
RED SPIDER—This pest is probably the worst, be- 
cause it is so widespread and attacs every kind of living 
plant. On evergreens it is especially destructive to blue 
spruces of all kinds, Blue cedars and all types of Red 
cedar. Tho not as bad, it dces damage the arborvitas 
some. The correct name of this pest is spruce mite, and 
like the plant lice it is a sucking insect. It seems to be 
especially damaging during hot dry weather. The insects 
infest the plants by the thousands and can be barely seen 
with naked eye. They suck the sap out of plants and 
destroy cells. Plants must be sprayed when they first 
appear, usually in late June and early July. Because the 
eggs are not affected with the spray, they must be 
sprayed three times, about five days apart. 
JUNIPER SCALE—This is becoming very prevalent 
on Pfitzer and Sabina junipers all over this area. If not 
controlled it kills the plant in several years. We spray 
in May. 
JUNIPER WEB WORM—Common all over in Irish, 
Swedish and Meyer’s junipers. Spray immediately or 
there will not be any foliage left on your evergreen. This 
small worm bunches upt the foliage with a fine web, and 
eats the foliage from the inside. 
PINE SAW FLY—This small worm works in colonies 
on pines, especially Mugho, Scotch, Red, Jack and Aus- 
trian pines. They simply eat off last year’s foliage before 
the new foliage comes out. Call us immediately and we 
will stop their feeding before further damage is done. 
PINE SHOOT MOTH—This pest lives in and destroys 
the tip buds in pines and causes deformity. It prefers 
Mugho Pine and Scotch Pine in this area. Spraying 
must be done the last of June and early July. 
@ There are many more pests that we encounter from 
time to time but the above list takes up 90% of our time. 
e If you wish someone to take the responsibility of 
spraying when they need it and keep your evergreens 
sheared at the proper time, call our office early in the 
season and our representative will call on you.
