Giant Arborvitae is a dense, pyramidal, hardy dark
evergreen tree. This variety is faster
growing than the species arborvitae.
The foliage can be sheared and kept
at desired height and width. The Green
Giant Arborvitae grows best
in full sun. Makes an excellent Living
Fence. Tough tree against wind and
rapid growing pyramidal deer resistant
evergreen. Its dense root structure
enables it to withstand wind storms.
When planted in full sun, every 5'
apart, a dense screen can be achieved
in three to four years.. Green Giants
take on a bronze color in winter.
They can reach a height in excess
of 35'. In addition, the Green Giant Arborvitae is deer resistant and is seldom bothered by insect pests.
Steven's Holly is a
robust evergreen Holly that grows well
in various landscaping situations. This
plant is a broadly shaped pyramidal tree
or tall shrub. The glossy dark green leaves
of the Nellie Stevens coupled with its
bright red berries provide stunning fall
coloring. The Nellie Stevens Holly is
a delightful addition to any landscape
and it does well as a "Living Fence"
TM OR as a specimen tree. This tree demands
fairly simple care. The Nellie Steven's
Holly can achieve a yearly growth rate
between 6-12" per year. This plant
does well in full sun and/or partial shade.
are nearly care free evergreens. In the
nursery the only insect we have seen damaging
the trees are tent caterpillars, which
can be swept off with a broom. The waxy
cuticle of the holly makes it difficult
for insects to penetrate. Aphids do attack
new succulent growth. If the infestation
is not severe, spraying is not necessary.
Once the new growth has hardened off,
insect activity will be slowed tremendously
or completely halted.
black spots(1-2mm in diameter) sometimes
appear on the holly leaves. I asked our
MD State Nursery Inspector what they were.
I could not find the causual agent. She
said that as the new leaves emerge, the
new cells occasionally sun scald. These
cells later blacken into the small black
circles. No treatment is needed.
popularity of the Leyland
Cypress as a "Living Fence"tm
screen is indeed no coincidence. This
vigorous plant can almost be seen growing
as it stretches its branches to the sky
in its quest for the clouds. In virtually
no time will this hardy and attractive
conifer form and shape itself into the
coveted "Living Fence"TM. This
soft-needled evergreen's leaves are medium
green in color. The Leyland Cypress is
happiest in the full sun and Pryor's Nursery
recommends it be planted in such locations
only, if the growth rate is to be achieved.
This hardy tree is pyramidal to cylindrical
in shape and it can grow as much as 1.5
feet per year or more. Its care is simple
but does demand water in the hot months
when young. These trees can grow very
tall at maturity but can be pruned indefinitely
to retain the desired shape.
no plant is trouble free, the Leyland
Cypress attracts few pests in the landscape.
The insect which may be present on the
Leyland is the bagworm. No preventative
measures are necessary. Treatment is only
needed when the insect's presence is detected.
They start appearing around July 4 and
are about the size of a grain of rice.
Products containing BT are effective against
the bagworm when they are in this early
stage. BT is a bacteria that attacks the
insect. Follow label instructions to the
the late 1970's, the leyland was thought
to be trouble free. But now we see on
some a cankar, which is a small wound
which leaks sap. While many people say
it's a problem, the state of MD Dept.
of Pesticides lecture given by Ethyl Dutkey
in 12/98 stated she observed some infected
plants. She noticed that when the plants
were taken care of properly(water, fertilizer,
etc.), the plants grew thru the problem
and are large, healthy plants. Therefore,
I am recommending no chemical treatments
pathogen. In conclusion, if a
leyland develops canker, a bona fide food
and watering program is recommended for
a quick recovery.
