  1. Narrowleaf Evergreens Unit 27 Horticulture

  2. Features of evergreens • Generally remain green year-round • Are adaptable to various soil types & weather conditions • May have needlelike or scalelike leaves

  3. 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. • Scalelike evergreens • Scalelike leaves overlap to form a flat spray • Example: Junipers

  4. 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)

  5. 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

  6. 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

  7. 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

  8. 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

  9. Watering • Need to water every 10 to 14 days during the first year after planting

  10. Pruning Two methods: • Pruning – cutting individual branches to give an “informal appearance” • Shearing – ends of small branches are cut in straight lines to shape hedges into a “formal appearance”

  11. Characteristics to Consider • Height • Hardiness • Foliage color • Period of interest • Landscape use • Ground cover • Foundation planting • Rock garden • Specimen – used alone • Screen plants & hedges
