Narrowleaf Evergreens
Unit 27
Horticulture
Features of evergreens
 Generally remain green year-round
 Are adaptable to various soil types &
weather conditions
 May have needlelike or scalelike leaves
Leaf types
1. Needlelike evergreens



Are attached in bundles called either
sheaths or fascicles
Drop old needles in the fall and new needles
are produced in the spring
Examples: Mugho Pine, spruce trees, etc.
2. Scalelike evergreens


Scalelike leaves overlap to form a flat spray
Example: Junipers
Uses
 Foundation plantings
 Boundary plants to accent property
boundaries
 Screen view of less attractive areas
 Control air currents (can be 5 to 10
degrees warmer on protected side)
Care
1. Three methods of shipping
 Bare root (BR)
 Balled & burlapped (BB)
 Container stock (C)
2. Storage
 High humidity and cool temps (33˚ to 40˚F)
 Heeling In – BB plants mulched in ground to
retain moisture around roots
 Water regularly
Planting Balled & Burlapped Plants






Prepare hole 1½ to 2 times as large as the ball
Place ball 1 inch above the original soil line
Remove burlap, twine & wire
Add soil to fill hole 2/3 full
Fill with water and let soak in
Finish filling hole with soil and form a berm
(saucerlike shape) around tree for watering later
Staking
 Use a stake over half as tall as the tree to be
staked
 Use two stakes of wood capable of lasting at
least two years
 Place one stake on the side of the prevailing
winds of the tree & the other on the opposite
side
 Use wire inside of a 1 foot piece of garden hose
to tie around the trunk, half-way up the tree on
each stake
Fertilizing
 Apply 3-6 pounds of a 5-10-10 fertilizer per
100 square feet in a circle under the drip
line (outer edge of tree branches)
 Fertilize before new growth starts in the
spring
 Water in with a garden sprinkler
Watering
 Need to water every 10 to 14 days during
the first year after planting
Pruning
Two methods:
1. Pruning – cutting individual branches to
give an “informal appearance”
2. Shearing – ends of small branches are
cut in straight lines to shape hedges into
a “formal appearance”
