68 SHRUBS— HEDGE PLANTS— LILAC— CLIMBING VINES 
The planting distance depends on the purpose for which the shrub is 
used, whether for a hedge, a group, or a shrubbery mass where the plants 
do not stand out individually. In this last case they must be set closely, 
the distance varying with the size which the shrub will eventually attain. 
As a general rule, the distance between shrubs in a mass should be one- 
third to one-half their ultimate height. Shrubs, as a rule, should not be 
planted in the shade. However, Barberry, Deutzia, Japan Quince, Snow- 
berry, and Privet will thrive in shady places. Weigela does especially 
well in the shade of trees, where many shrubs would fail. 
Lilac SP^*i® holes large enough to hold the roots without crowding. 
Cut off any broken or damaged roots. Set the plant 5 to 7 
inches deeper than it stood in the nursery, but do not fill in the last 5 
inches of dirt until the plant has made a good growth. 
Do not prune the Lilac at planting-time except to remove broken or 
uneven branches. The LUac requires little pruning at any time. Remove 
the withered flowers; any weak branches can also be removed at this 
time. The branches may be thinned as they need it. Cut them out 
entirely; do not cut them back. 
For hedges, set the plants 1 H to 2 feet apart. For growing flowers 
for market, 3 feet apart, in rows 4 J4 feet wide. 
TTf»f1aA Plantc hedges of Privet, Japan Quince and Barberry, 
xacugc jrirtuis ^p^^^^ ground for a strip 1 feet wide. Set the 
plants 1 foot to 1 feet apart in the row, depending upon how dense a 
hedge is desired. The plants should be set 4 to 5 inches deeper than they 
stood in the nursery row, but do not fill in the last 4 or 5 inches until the 
plants have made a good growth. A very desirable hedge can be made 
by planting a double row. The ground should be spaded for a strip 2 
feet wide. The rows should be set 1 foot apart, with the plants 1 feet 
apart in the row. The plants of one row should come opposite the open 
spaces of the other row. 
A good hedge of Spirea can be made by setting the plants 1 to 
2 }4 feet apart. Roses suitable for hedge can be set 1 to 1 feet apart. 
Tall-growing shrubs should be set 1 K to 2 }^ feet apart. 
Climbing Vines 
Japanese ^ hole that will take the roots without crowding. Put 
pi the crown in 1 inch deep. Clematis thrives best on a sandy 
V^iemaiis location, and should have a rigid support. If a string or 
wire is loose, it allows the wind to blow the plant about so as to injure it. 
Prune heavily. Cut out all of the weak growth and during the winter 
prune the remainder heavily if you want the most bloom. 
Boston Ivv plants as deep as they stood in the nur.sery. Pro- 
" tect the top, after the first season's growth, with a 
mulch of leaves or straw, as the young growth is sometimes injured the 
first winter after planting. When established it is very hardy. It will 
climb and cling to wood, brick, rock, etc., anything except an iron sup- 
port, which gets very hot during the summer. 
Wistaria plant as deep as it stood in the nursery. Keep it 
hoed the first summer, but after that do not fertilize or 
attempt to force the growth, because it takes several years for it to come 
into blooming, and it will be even longer coming into blooming if the 
growth is forced by cultivating and fertilizing. It should have a very 
strong, permanent support, for it is a long-lived vine and eventually be- 
comes very heavy. The best method of training is to let it alone. It 
then produces rugged, twisted branches which are very efl^ective. Where 
it is desired to cover the entire surface of a building or arbor it is 
necessary to keep the leaders taut and to train the outside branches
