Fir trees are easy to take care of as long as you remember a few tips.
When planting your fir tree, make sure that the soil is well-draining and that the tree will have adequate room to grow throughout the years. Fir trees prefer part-to-full sun and can thrive in USDA Zones 3-8 depending on the type of fir.
The best time to plant your Fir is while it is still dormant, which is late fall to early winter. This will ensure that the tree can create a good root system before the spring when it is using its energy for growing.
Before putting your Fir tree in the hole to be planted, make sure that both the root ball and hole have been soaked thoroughly. This will help to keep the plant moisturized while it is newly planted.
Watering with an irrigation hose weekly for approximately an hour will do wonders for a newly planted Fir.
