A suitable fertilizer in the early spring every year will keep it growing well and fight off most of the diseases.
This mostly comes down to protection against the elements and adequate watering through the winter. Water The darkish green needles on most Pseudotsuga species are 2-3cm long, flat and soft, and should be clear of spots or brown bands when inspected closely. The older needles on the inner parts of the branches, eventually discolor and drop, typically in autumn. This is normally much more evident on the lowest parts of the tree, particularly when shaded out by upper foliage– as they aren’t getting much light and therefore aren’t useful for photosynthesis, and are shed.

Identifying Features: Fraser Fir is one of the smallest fir trees, which helps make its seed cones more visible and helps distinguish it from other firs, as does the sometimes very dark green leaves. It is similar to Balsam Fir but not as spire-topped, and its leaves are usually a bit more conspicuously notched. Subalpine Fir is also similar but has much lighter green leaves.
It grows in temperate rainforests from 0 – 7500 ft and prefers high rainfall and cool, humid summers. It is very shade-tolerant and grows slowly but well in the shade of other trees. Identifying Features: The leaves of the Siberian Fir are usually a lighter green than most other firs, excluding perhaps Douglas Fir, which has radially arranged leaves that go around the entire twig and downward hanging seed cones. Its twigs are yellow-gray rather than the brownish or reddish often seen in firs. The bark is sometimes gray-green and seldom develops any deep grooves as it ages.

Pine needles are relatively long, soft, and grow in clusters. Spruce needles are shorter and sharper and don’t grow in clusters. A little close-up inspection can reveal the cause. If you’re seeing your Doug fir declining, I’d love to share my knowledge and experience (and a little bit of science) with you. There’s every chance we can get it looking healthy again. On the other hand, a Douglas fir specifically won’t thrive when it’s overwatered either– or on boggy, marshy, poorly-drained soil. They’re not as intolerant as some evergreens to this state (such as yew) but excessive browning and needle drop (coupled with poor growth) can also be seen in such Pseudotsuga specimens. Bark on Fraser fir trees has a grayish-brown appearance that becomes scaly as the tree matures. Fraser fir tree has small conical cones that are purple in color that turns light brown before disintegrating and spreading seeds.
Identifying Features: The Sacred Fir can be differentiated by its leaves that have a pointy (acute) tip rather than blunt or notched like most other fir trees. There are only stomata on the lower leaf surface and not the upper. While the leaf arrangement appears similar to Pacific Silver Fir, their middle leaves tend to point upwards more than forwards. The Red Fir sometimes has acute leaf tips, but its leaves are 3-4 sided rather than flat.Identifying Features: The leaves of the Pacific Silver Fir, with its somewhat unique two-ranked leaves with longer horizontal leaves and central leaves that point forward, help distinguish it from other fir trees. Sacred fir has a similar leaf arrangement, but it has pointy rather than deeply notched leaf tips. The distinctive bark that does not turn as brown and furrowed and retains its resin blisters longer will also allow you to distinguish it from other firs.
True fir cones tend to be more smooth, and while they do have bracts, they tend to be shorter, unforked, and usually much less conspicuous than those of Douglas Fir. Fraser Fir is sometimes treated as a subspecies of Balsam Fir, though plant taxonomy authorities report otherwise. Swiss needlecast and rhabdocline needlecast are both fungal diseases that cause excessive needle drop of inner needles (usually sparing the newest needles at branch tips). April to late August is suitable for pruning many conifers. Most conifers will not regrow from old, bare wood (yew is an exception), so lightly trim or remove new growth tips to control size. Before a conifer becomes too tall, prune the top off the main vertical trunk to slow further upward growth.
What is the difference between a Pine tree and a Fir tree?
Spanish Fir is a gorgeous medium-sized tree with a symmetrical conical crown with branches that usually grow to near ground level. These trees belong to the species Abies and are woody in nature. It is available in more than 50 species and a lot of cultivars. Fir Tree Identification
