What does new growth on a spruce tree look like?
The new growth is easy to identify because it is brighter in color and the needles are soft. Picking spruce tips from a standing tree is a good exercise in self-control and judgment. Every tip that's picked is pruning the tree.
The spruce gall adelgid group consists of the Eastern spruce gall adelgid and the Cooley spruce gall adelgid, both of which cause pineapple-shaped growths near the ends of branches. The Spruce gall midge causes cylindrical shaped growths at the ends of branches.
Current-year needles green and buds healthy. Infected older needles turn brown to purple and fall off lower and interior branches. Fruiting bodies appear as small black dots or black lines on needles.
The tree will probably replace any lost needles over the winter. Just be sure to give it plenty of water, especially if it's been drought-stressed.
Cover the seeds with a couple of millimeters of vermiculite or failing that a fine layer of sieved compost. Follow with a gentle watering and keep them at room temperature. Germination will begin within a 10-14 days of sowing.
This abnormal growth is called a burr. In American English it's known as a 'burl', so you may find it referred to as both. The growth is a mass of shoot and bud tissue that grows manically and forms a distinctive growth on the trunk. At its most basic, it's not unlike a benign tumour in an animal.
These galls are produced by insects called Cooley spruce gall adelgids (woolly aphids). Galls appear early in the season as 2- to 4-inch cucumber-shaped growths. The galls are light green during late spring and early summer but dry out and become brown starting in mid-July. The galls often are mistaken for seed cones.
The most important disease of spruce is Needle Cast disease caused by fungal pathogens such as Rhizosphaera spp. and Stigmina spp. (Figure 1). The symptoms include browning of needles, needle dropping and branch dieback.
Growth and Yield- Blue spruce is apparently a long-lived tree, surviving up to 600 years or more. Diameter growth is slow; trees 10 to 13 cm (4 to 5 in) in d.b.h. may be 125 to 135 years old; at 46 to 56 cm (18 to 22 in), they may be 275 to 350 years of age (84).
Symptoms - The disease is usually first evident on lower branches and then works upward gradually. Second-year needles turn a purple or brown color and eventually fall from the tree. After several successive years of needle loss branches may die. In general, trees appear to die from the bottom upward.
Should you cut dead branches off a spruce tree?
When pruning, follow the general branching pattern to maintain the natural shape. Remove dead, diseased, or broken branches anytime. When shearing, begin in late spring or early summer when new growth begins. This allows cuts to heal and new buds to form for next year.
When you detect some of the symptoms early, you can sometimes save your spruce trees. However, you need professional help to treat some of the diseases that kill spruce trees. On the other hand, if the trees can't be saved, you can replace them with a different kind.

Unfortunately, once needles on an evergreen die they do not come back. However, if treatment begins early in development, new growth can come in, and the damage will appear less noticeable over time. While the Blue Spruce is most affected by this fungal disease, White Spruce and Norway Spruce may also be infected.
A spruce or jungle sapling cannot grow if it is part of a 2×2 square of saplings that doesn't meet the requirements for a giant tree. Except for giant jungle and giant spruce (as noted above), sapling growth is not affected by nearby blocks on the same level as the sapling(s).
If the browning is not severe, the tree may survive. If buds and stem tissue are still green and soft, the tree should produce new shoots and foliage, although needles that were damaged extensively will lead to areas devoid of foliage.
For small numbers it is easiest to do this by sowing them, and then chilling them in the pots. After that they need warmth and light to germinate, which may take several weeks. The soil must remain moist, but not wet, at all times.
Irregular tumor-like growths called galls are found on stems and roots. They range in size from 1/10 inch up to 1 foot in diameter. New galls are round, rough textured, light colored and may be smooth and slightly spongy. Older galls become hard and dry.
How to tell if a tree is struggling with a disease: Premature leaf defoliation or reduced foliage. Leaves or needles with dark spots, unusual colors, or distorted shapes. Changes in tree bark.
Burls. Burls are identifiable by their appearance: a large, knobby growth on a tree trunk or branch, developed as a protective response to tree disease, and covered in bark. They're not inherently harmful to the tree, but they are thought to reduce a tree's vigor - although not as much as a rampant disease would.
Shape: Spruce tree needles are almost square-shaped, with distinct sides you can feel when you roll a needle in between your fingers. Their tips are pointy and sharp. Texture: Two words—stiff and smooth.
What do spruce mites look like?
Spruce spider mites are small, 0.5 mm (1/50 inch), but can be seen with a hand lens. The young are pale green when they first hatch but become very dark green to dark brown as they age.
On spruce trees, the disease appears as sunken, resinous areas surrounded by swollen callus, giving a gall-like appearance. Small black fruiting bodies may occur on the canker. Once the branch is girdled, needles may yellow or redden. The branch eventually dies.

Using a balanced fertilizer, fertilize spruce trees sparingly, preferably in late winter or early spring. Avoid over-fertilization, leading to excessive growth and weakening the tree's structure.
Soil and Water
A spruce grows best in moist, well-drained, loamy soil amended with organic matter, but it will adapt to clay or sandy soils, too. It's not fussy about pH and can tolerate acidic, neutral, or alkaline soils. Water spruce regularly and deeply, especially during the first year after planting.
Spruce trees should be watered if there is less than 1 inch of rainfall per week. Adequate root formation requires you to water Spruce trees down deep at a slow rate. Placing the hose at the base of the Spruce and setting the water flow on trickle will allow the water to seep in deep into the soil.
