THINGS YOU MAY WANT TO KNOW 
TYPES OP TREES 
Dwarf: plume cypress, juniperus Sabina, juniperus pfitzer- 
iana, Mugho pine, Globe Arborvitae, Taxus cuspidata. 
Slow growing: Arborvitae of all kinds, and Hemlock, 
past growing: Remainder of varieties listed. Growth per 
year, from 6 inches to 1 foot after the first year. The growth of 
any of the fast growing varieties may be retarded by pruning the roots, 
pruning the tops, or nipping off the terminal buds. 
ADAPTATION TO VARIOUS CLIMATES 
Our trees have been successfully grown in all parts of the 
country. Except under unusual circumstances, soil conditions are al¬ 
most as important as geographic locations . 
SOIL CONDITIONS 
pines prefer a light to medium soil; sunlight, spruce: A 
heavier soil, moderate sunlight, except Norway spruce which will grow 
in fairly light soil. Larch: medium to heavy soil and sunlight. 
Arborvitae*. good soil, will stand moderate sun but not extreme ex¬ 
posure. pir and Hemlock: heavy soil, best for shady locations. 
ABOUT COLORADO BLUE SPRUCE 
Trees grown from the seed of Colorado Blue spruce range from 
real blue to blue-green. About 20% are ordinarily a good blue color -- 
the balance of the trees we are offering run better than average color. 
The color may be improved by applying as fertilizer a small amount of 
nitrate of soda -- which our trees have not had as we must grow them to 
stand any adverse conditions (poor soil, etc.) they may meet with after 
leaving the nursery. 
ROOT PRUNING 
Root pruning is not necessary when trees are in their per¬ 
manent places, it is helpful, however, in making a tree dense, since 
a tree»s root system is about equal to its crov/n (foliage), to root 
prune, cut around the tree with a sharp spade at about the same dis¬ 
tance from the base as the tips of the branches are from the trunk. 
Root pruning is advisable when trees are to be moved at some future 
date. The removal of lateral terminal buds in late fall or early 
spring also helps to make trees dense. 
SHIPPING DATE 
Usually we start shipping from about April 10, depending 
on weather conditions, shipments are made as early as possible, un¬ 
less otherwise instructed, if this seems late in some sections, 
remember that sturdy, DORMANT trees will be all right even if it is 
warm where they are to be planted, if they are watered when planted 
(and if very warm at short intervals thereafter) they will more than 
show their appreciation. OUR TREES ARE GUARANTEED TO LIVE!
