Conifers - Guides
Conifers are often considered low maintenance, but long-term success depends on choosing the right plant and giving it enough room from the beginning. Focus on climate, mature size, drainage, sunlight, establishment watering, and natural growth habit before deciding where to plant.
Choose the Right Conifer Before You Plant
Start with mature size and climate. A compact dwarf Mugo Pine and a mature Eastern White Pine require completely different amounts of space. Likewise, firs, Colorado Blue Spruce, and warm-climate Arizona Cypress have very different environmental needs. Check hardiness, heat tolerance, sun, drainage, and mature spread first.
Plant and Water Conifers for Strong Establishment
Good drainage is important for many conifers, but newly planted trees and shrubs still need consistent moisture while their roots establish. Water deeply rather than frequently wetting only the surface, and avoid planting too deeply. Species requirements vary: Balsam Fir, White Fir, and Korean Fir should not automatically be treated like drought-adapted pines or junipers.
Plan Privacy Screens for Their Mature Size
Fast-growing screens can solve a privacy problem quickly but create another one if planted too close together or too near buildings. Compare narrow ‘American Pillar’ Arborvitae, larger ‘Green Giant’ Arborvitae, and vigorous Leyland Cypress before deciding on spacing. Upright Italian Cypress, ‘Spartan’ Juniper, and ‘Ellwoodii’ Lawson Cypress can suit narrower spaces.
Prune Conservatively and Respect Natural Form
Most conifers look best when pruning works with their natural shape rather than forcing them into a size they cannot maintain. Avoid cutting indiscriminately into old bare wood because many conifers do not regenerate readily from it. Groundcover Creeping Juniper, Common Juniper, large Cedar of Lebanon, and architectural Monkey Puzzle Tree all need very different approaches. Selecting the correct mature size reduces the need for corrective pruning later.
Understand Deciduous Conifers and Special Cases
Not every conifer stays green through winter. Dawn Redwood, Bald Cypress, and Pond Cypress naturally shed their foliage, so seasonal browning is not necessarily a sign of trouble. Ginkgo is another deciduous gymnosperm often associated with conifers in horticulture, although it is botanically distinct.
Regional suitability matters too. Monterey Cypress, Pinyon Pine, Slash Pine, and Stone Pine thrive under very different climatic conditions.
