Growing your own Christmas tree offers the satisfaction of cultivating a future holiday tradition, whether for harvest or for long-term landscape enjoyment. Success in growing coniferous seedlings relies on reducing initial stress and ensuring the trees have the best possible environment to transition from nursery stock to established evergreens. This process demands attention to detail, from selecting the right species for your region to employing meticulous post-planting care, which determines the long-term health and shape of the tree.
Preparation: Choosing Species, Timing, and Site
The first step is selecting a species that thrives in your local climate and soil conditions. Popular choices include the Fraser Fir, known for its pleasant aroma and excellent needle retention, and the Scotch Pine. Other options include the Virginia Pine, favored in the southern United States for its hardiness, and the White Pine, popular for its soft, flexible needles. Consulting your local agricultural extension office provides guidance on species best suited for your specific area.
Optimal planting occurs during the dormant season, typically in early spring before the buds swell. Spring planting allows the root system months to establish before summer heat arrives. A secondary window is available in late fall after dormancy, but this risks root damage from winter heaving or cold.
The chosen site must offer well-drained, slightly acidic soil (pH 5.5 to 6.0), as conifers cannot tolerate standing water or root rot. Full, all-day sunlight is required for the dense, symmetrical growth desired. Seedlings should be spaced six to eight feet apart within rows, separated by at least eight feet to allow for air circulation and equipment access.
Step-by-Step Guide to Planting Seedlings
Once site preparation is complete, focus shifts to the mechanics of planting and handling the nursery stock. Bare-root seedlings, often preferred for large-scale planting, must be kept cool and their roots constantly moist until planted. If planting is delayed, temporarily “heel in” the roots by burying them in a trench of moist soil.
The planting hole should be dug wide enough for the roots to spread horizontally without bending or circling. For container-grown stock, the hole should be only as deep as the root ball. Place the seedling vertically, ensuring the root collar—where the roots meet the stem—is flush with the surrounding soil surface.
Backfill the hole with the original soil, using a gentle tamping motion to firm the soil and eliminate air pockets. Air pockets are detrimental because they dry out root hairs, preventing water and nutrient uptake. Avoid excessive compaction, which impedes root growth and limits oxygen and water movement. Once filled, a shallow ring of soil can be created around the seedling to help capture water.
Post-Planting Care and Establishment
Immediate and ongoing watering is crucial for the survival of newly planted seedlings during establishment. An initial deep watering settles the soil and ensures good root-to-soil contact. For the first few months, keep the soil consistently moist, especially during dry periods, but allow it to dry slightly between cycles to prevent waterlogging.
Competition from weeds and grass must be actively managed, as they compete with small seedlings for water and nutrients. Apply a three to four-inch layer of organic mulch, such as straw or wood chips, around the base of the tree to suppress weeds and retain moisture. Keep the mulch a few inches away from the trunk to prevent moisture buildup, fungal issues, and rodent attraction.
Protecting young trees from animal damage is necessary. Deer browsing can destroy the terminal leader (the main upright shoot), ruining the tree’s future shape. Physical barriers like Vexar tubing, wire mesh cages, or deer fencing are the most reliable protection methods in high-population areas. Rodent damage is mitigated by maintaining a weed-free area directly around the trunk, removing their protective cover.
