The Blues Weeping Colorado Spruce: Cultivation And Care
Homing the native plant of America for its rustic silvery blue foliage can be the all-time wish of many gardeners.
So, provide the evergreen conifer with all the care it demands. The major 8 requirements are listed below.
1. Sunlight Requirement
Provide the plant at least 6 hours of full sun daily. However, place it in partial shade during the summer afternoons if growing it in the hardiness area above Zone 8.
The protection is to prevent the burning of the leaves from scorching light and damaging the plant’s look.
Meanwhile, the Blue Colorado Spruce enjoys direct morning light. You can maintain the light requirement even with a grow light.
2. Temperature Range
The Blues Weeping Colorado Spruce prefers moist and cool climates.
Meanwhile, avoid higher temperatures as much as possible as they can stunt the Blue Colorado Spruce growth.
So you can try balancing the hot days by misting the plant to drop the temperature and providing the plant with proper ventilation.
3. Humidity Level
Maintain higher humidity (70-80%) during spring and summer. In contrast, drop it to 55-65% during fall and winter for sturdier growth.
You can maintain humidity by installing a humidifier for indoor potted Blue Colorado Spruce.
As for the outdoor tree, you can plant it nearby a damp place or have a water reservoir near the plant.
However, avoid excess air moisture near the Blues Weeping Colorado Spruce as it invites diseases and pests.
4. Water Need
As a drought-tolerant plant, the Blue Colorado Spruce does not like stagnant water.
Also, check at least 4 inches of topsoil, if the planter exceeds 8 inches in depth, for any moisture to prevent overwatered conditions.
Alternatively, you can check the moisture using a soil tester and water it according to the reading.
Also, use a watering can with longer spouts to let the water fall directly into the soil.
5. Soil Requirement
Well-draining, slightly acidic soils (pH 5.5-7.0) rich in organic matter fit the Blue Colorado Spruce. Sandy soil or slightly clayey soil can fit the description.
Such conditions result in overwatering, which can cause your Colorado Blue Spruce leaves to turn yellow and suffer from root rot.
So, for the best, keep the soil well draining and slightly moist to enjoy a healthy tree. Meanwhile, improve the degraded soil quality by adding manure or nutrient soil.
6. Fertilizer Appliance
Fertilize the plant with balanced slow-release fertilizer 2 to 4 times a year and water it immediately to prevent root burning.
It is better to apply fertilizer in spring and summer, decrease during fall, and cease in winter.
Increase the potassium dose in the fall to help thicker trunk growth. Do it until the tree matures and then return to the normal dose, as mentioned above.
You can also use slow-releasing organic fertilizer, as the Blue Colorado Spruce needs support throughout its long lifespan.
7. Occasional Pruning
Pruning is not mandatory for the growth of the Colorado Blue Spruce as the plant features a triangular structure and does not hamper the growth of lower branches.
However, if the foliage becomes too dense, you might have to prune one or two branches to reduce the fight for nutrients.
Diseases like fungal tip blight, needle cast, and cytospora canker can trouble the tree leading to sticky tips, needle drops, and leaf scars.
So, you can snip off broken twigs or trim them off to give any shape but leave half their size during winter or early spring.
8. Repotting and Aftercare
Mostly conifer gardeners plant the Colorado Blue Spruce during the spring and fall time of the year, which attains a growth of 12 inches yearly.
This growth pace can make the potted Colorado Blue Spruce easily root bound within 5 years of plantation.
Meanwhile, restrain from removing all of the original soil from the trunk to refrain from stressing the tree.
