QUESTIONS AND ANSWERS 
Which vines do you recommend 
for a clapboard house? 
Plant Clematis and let them 
climb on a trellis which is hinged 
at the bottom. When the house 
needs to be painted, lay trellis 
down. Thorndale Ivies or Euony- 
mus vegetus could also be trained 
on a trellis. Do not permit them to 
cling to the clapboards of the house. 
Are vines harmful to brick or 
stone walls? 
Contrary to some opinion, vines 
do not keep walls moist. I have 
seen churches in Europe covered 
with English Ivies that are more 
than a hundred years old. 
How can sparrows be kept out 
of vines? 
They will be discouraged from 
returning if you will brush a long 
stick over the vines a few times. 
Will Thorndale Sub-Zero Ivies 
grow in Montana? 
They should survive the low tem- 
peratures in that section under a 
heavy blanket of snow if planted 
as a ground cover. The vines would 
probably winter-kill above the 
snow line. 
Can Thorndale Ivies be grown 
indoors? 
Yes. They prefer a cool light place 
away from direct sunlight. Wash 
leaves by holding branches under 
the cold water faucet every few 
weeks to keep them clean from dust 
and red spider. 
From Arizona—would you rec- 
ommend Thorndale Sub-Zero 
Ivies for our hot, dry climate? 
For shady places under trees or 
on walls or chimneys on the north 
side, yes. Keep them well watered. 
In northern states they will do as 
well in sun as in shade but I would 
not plant Thorndale Ivies in an 
open location in your state.

What is the easiest way to get rid 
of brown scales on Euonymus? 
Spray with Chlordane or other 
available scale insecticide which 
you may purchase from your local 
hardware or seed store. Prevention 
is better than cure. Spray vines 
with cold water from time to time 
as recommended in another section 
of this book. A healthy plant is less 
subject to attack by insects and 
fungus diseases. 
What ground cover plants will 
grow under a Norway Maple? 
Pachysandra is probably your best 
bet. The dense shade under a 
maple tree and the fact that their 
roots are near the surface makes it 
difficult to grow any plants under 
them. If Pachysandra won't grow, 
cover ground under the tree with 
tanbark or crushed gravel. 
Do you recommend spring or fall 
planting? 
For such perennial-like plants as 
vines and ground covers I lean to- 
wards spring planting, especially 
in northern states. The plants will 
be firmly rooted and better estab- 
lished in their permanent location 
and so will better withstand alter- 
nate thawing and freezing. 
Will Thorndale Ivies do well un- 
der Oak trees? 
In well prepared ground they will 
get a good start within the first sea- 
son. Be sure to keep them well 
watered. Do not neglect to feed 
the oak tree itself. A balanced fer- 
tilizer should be applied below the 
surface by means of a feeding rod. 
Space is up and a lot of ques- 
tions are left unanswered. We'll try 
to tell you more next time.
