Fir Care Tips
Fir trees and shrubs grow best in full sun or part shade and moist, fertile soil. Sandy loam soil is best. Fir will occasionally adapt to poor, compacted soils and planting places that are prone to heat and drought, but it often languishes in such conditions and grows exceptionally slowly. Fir is not a good choice for gardening Zones 8 and above; look for other options in hot, dry regions of Zone 7. Plant fir in early spring, as this group of trees and shrubs does not do well with summer’s heat and dry conditions. Resist autumn planting, too, since a young fir won’t get adequate time to acclimate before drying winter winds damage it. Water fir well after planting and continue watering regularly so it receives at least one inch of water from rainfall or irrigation each week during the first growing season. Regular watering encourages a strong root system. Spread a 2-inch-thick layer of mulch over the root zone to help conserve soil moisture.
