How to Grow Fraser Fir Trees
Fraser firs are one of the most popular Christmas tree species that gardeners plant. Though very particular about their soil pH and type, they can grow over 80 feet tall with proper growing conditions and maintenance. Soil that has draining problems raises the risk of these trees contracting root rot. The firs do very well in shady environments and commonly survive under thick canopies. May and June sees both male and female blossoms from the crown to the outer tips of the branches. Does this Spark an idea?

1
Analyze the soil at your planting site. Fill two-thirds of a jar up with soil and one-third water. Shake the jar and wait 24 hours. Sand settles at the bottom of the jar, loam second and clay settles at the top. If clay makes up more than 50 percent of the soil than avoid planting your fraser fir on that site or make soil amendments with sand and compost.

2
Conduct a soil pH test on your planting site. Fraser fir trees grow in an acidic soil pH range between 5.2 and 5.8. A range higher than that will cause yellow foliage and brown needles. You can purchase a soil testing kit at your local gardening supply store. Routinely test the site up to eight years after planting.

3
Fertilize each spring with a fertilizer that contains ammonium sulphate, which can aid in keeping an adequate soil pH range.
-
4
Keep the soil moist by spreading mulch underneath the tree. To ensure that the tree doesn't become over saturated, plant the fir in a raised bed 6 to 8 inches in height.
-
5
Apply a fungicide such as Subdue MAXX each spring and fall to reduce the risk of fungal disease development. Subdue MAXX only protects trees from getting a fungal disease and will not save a tree infected with the fungus phytophthora.

Tips & Warnings
Fumigate the soil with a soil fumigant that contains methyl bromide to reduce the risk of fungal diseases in the soil.
Avoid fertilizing in the summer to prevent causing new growth that can be harmed during winter months.
