Picea glauca 'Conica' (Dwarf Alberta Spruce)

Though Picea glauca 'Conica' doesn’t specifically attract wildlife in large numbers, it provides shelter for small birds and animals. The dense branches offer nesting opportunities for birds, while the foliage can protect small mammals from predators during colder months.

• Seasonality: Evergreen; retains its foliage year-round
• Flowering Season: Conifers like Picea glauca 'Conica' do not produce showy flowers, but instead form small cones.

Foundation Plantings: Perfect for flanking entryways, walkways, or corners of buildings

Accent Specimen: Provides structure in garden beds or rock gardens

Container Gardening: Ideal for year-round interest on patios or porches (must be insulated in cold winters)

Miniature or Formal Gardens: Excellent for small spaces or topiary

Winter Interest: Evergreen color and tidy form make it a standout in all seasons

The leaves are needle-like and dense, offering a rich, bright green color throughout the year. The needles are soft to the touch, fine-textured, and densely packed on the tree, which gives Picea glauca 'Conica' its famous compact, symmetrical shape. The foliage provides year-round interest, especially in winter landscapes.

While the plant does not produce traditional flowers, it develops small, inconspicuous cones that appear in late spring or early summer. These cones are typically brownish and do not add significant ornamental value but are an integral part of its reproductive cycle.

• Planting Season: Best planted in early spring or fall when temperatures are cool.
• Soil Requirements: Prefers well-drained, acidic soil but is adaptable to a variety of soil types, including sandy or loamy soils.
• Spacing: Allow 3-5 feet of space between trees to accommodate their spread.

Planting Instructions:

1. Dig a hole twice the width of the root ball and just as deep.
2. Place the tree in the hole, ensuring the top of the root ball is level with the surrounding soil.
3. Backfill with soil, pressing down gently to eliminate air pockets.
4. Water thoroughly after planting to help settle the soil.

Little to no pruning is required to maintain the natural, dense, conical shape of Picea glauca 'Conica'. However, you can remove dead or damaged branches in late winter or early spring if necessary. Avoid heavy pruning, as it may disrupt the tree's natural form and slow its already minimal growth rate.

Water regularly during the first growing season to establish deep, healthy roots. Once established, Picea glauca 'Conica' prefers consistent moisture but is somewhat drought-tolerant. Water during dry spells, ensuring the soil remains moist but not waterlogged.

• This dwarf spruce thrives in full sun but can tolerate partial shade. However, planting in full sun is recommended for the best growth and color development. In too much shade, the plant may lose its compact form and become sparse.

There is no need to harvest anything from Picea glauca 'Conica', as it is used primarily as an ornamental plant. The small cones that form do not have significant decorative or functional value.

Fertilize in early spring with a slow-release, balanced fertilizer (10-10-10). Established trees generally require minimal feeding, but annual fertilization can help encourage healthy growth, especially in poor soil conditions.

• Mulching: Apply a 2-3 inch layer of mulch around the base of the tree to retain moisture and protect the roots from temperature fluctuations.
• Pest and Disease Resistance: This plant is generally pest-resistant but can be susceptible to spider mites in hot, dry conditions. Regular watering and maintaining good air circulation around the plant can help prevent this issue.
• Winter Care: Picea glauca 'Conica' is winter-hardy but can suffer from windburn in exposed locations. Plant in a sheltered area or use burlap wrapping to protect the foliage during severe winter conditions.

• Picea glauca 'Conica' is monoecious, meaning each plant has both male and female cones.
  
• Pollination is wind-driven, and cones are not typically prominent on dwarf forms like 'Conica.'
  
• Though capable of producing cones, fruiting is rare and not required for aesthetic or functional performance.
  
• This variety is grown for its foliage and form, not reproductive structures.
