Balsam Fir Care
These aromatic trees are best planted in the spring or fall when bought as bare roots plants. For container-grown plants, they can be planted any time of year, and it is best to get them into the ground as soon as possible. Balsam fir trees are often used as privacy screens and windbreaks. They do not require much care other than the occasional watering. Pruning is not often needed except to remove damaged or dead branches.
This type of easy-to-grow fir tree is not often plagued with pests or diseases. However, they are not immune to problems from balsam wooly adelgids, bark beetles, spruce budworms, aphids, scale, root rot, cankers, needle rust, or blight. They are not very tolerant of pollution from urban areas.
Balsam fir trees do well in full or partial sunlight. Newly started trees prefer sheltered areas for the first year of growth.
Balsam fir trees require sandy, loamy, acidic soil to thrive. Moist, but well-draining soil conditions are key to a healthy balsam fir tree. These trees do not handle clay soils well. Try applying several inches of mulch to the top of the soil to help retain moisture.
Established balsam fir trees only require supplemental water during prolonged droughts. For young trees, water weekly until established. These trees really soak up the water, so be sure to water very heavily. It’s important though that you not water quickly. Water should be released slowly over an extended period of time.
Temperature and Humidity
Balsam fir trees enjoy cool weather and do not handle heat and humidity well. They thrive in USDA hardiness zones 3 to 5. As an evergreen variety, these trees sport their deep green needles year-round.
Fertilizing young trees once in the spring can help encourage new, healthy growth. They respond well to well-balanced fertilizer. However, too much fertilizer can cause damage to these trees. They do not need fertilizer more than once a year and mature trees do not require fertilizer at all.
Propagating Balsam Fir
Propagating balsam fir trees through cuttings is possible, though it can be difficult to achieve. Many cuttings end up dying. However, by being aware of a few things, you can tip the scales in your favor and hopefully end up with a thriving cutting.
First off, cuttings are more likely to take root when taken from shorter, younger trees. Take cuttings in the spring or summer, selecting a branch from the bottom half of the tree. Gather the following supplies: a sharp pair of garden snips, a small pot, well-draining, moist potting soil, a plastic bag, a rubber band, and a mister bottle.
- Using sharp garden snips, trim a cutting that is about 6 inches long.
- Remove the needles from the lower part of the cutting.
- Dip the cut end into root hormone.
- Bury the cut end several inches into the moist potting soil, then gently press the soil around the cutting.
- Mist the soil to keep it evenly moist.
- Place the plastic bag over the cutting, securing it to the pot with the rubber band.
- Open the bag daily to allow it to receive fresh air and to check the soil. Mist when needed.
- The cutting should root in about a month.
- After this, remove the plastic bag and keep the cutting in a partially shaded area.
- Keep the new tree in a protected area for around one year, then acclimate it to full sun the following season. Plant it in your landscaping location.
How to Grow Balsam Fir From Seed
Propagating balsam fir trees from seed is the most popular and most successful form of propagation. To do this, follow these steps:
- Cold stratify the seeds by placing them in moist sand or potting soil inside a plastic bag. Then place them in the refrigerator for one to three months. Another option is to plant directly into the garden in the fall, where the cold temperatures will naturally stratify the seed.
- Once stratified, plant the seeds around 1/4 inch deep into moist, well-draining, sandy, loamy soil.
- Keep the soil moist. Germination should occur in about a month.
- Once the seedling is several inches tall, replant to a larger pot and keep them in a shaded, protected area for one year.
- During the following year, acclimate the seedling to full sunshine and plant it in your location of choice.
Because these trees are native to naturally cold areas, they are designed to withstand cold winters. Therefore, all that is needed to overwinter these trees is to add an extra layer of mulch to help insulate the roots.
Common Problems With Balsam Fir
Balsam fir trees are rather hardy and do not often struggle with many problems. However, yellowing needles and rot resulting from various conditions can affect their growth.
Yellowing Needles and Stunted Growth
If the needles of a balsam fir begin yellowing and the tree is not growing as it usually does, this can be a sign of root rot. This is caused by too much water in the soil. If these signs present themselves, cut back on watering and allow the soil to dry out. If the soil is not draining properly, try adding in sand to increase drainage.
Weakened Structure and the Presence of Mushrooms
Another problem that may come up with balsam fir trees is the growth of mushrooms out of their trunks or branches and a weakened structure that may break easily. These are signs of heart rot, which is a form of fungus that attacks the innermost wood of the tree. This may occur from the fungus entering into a wound on the tree or from the tree weakening because of less than ideal conditions. If this occurs, remove the damaged or infected branches, if possible. Be sure not to damage the branch collar.
With ideal conditions, the balsam fir will grow about one foot each year. They will reach their mature size anywhere from 15 to 30 years.
These evergreen trees have a tall, conical shape and flat, dark green needles with silver-white bands on their undersides. Their bark is thin, gray, and covered with little resin blisters. The upright cones start out purple and mature into a gray-brown color.
Yes, balsam fir trees have an unmistakable evergreen, spicy aroma.
