Pollination of the Dwarf Japanese Cedar (Cryptomeria japonica 'Globosa Nana') occurs through wind dispersal. The plant produces cones which contain both male and female reproductive structures. The male structures release pollen into the air, which is then carried by the wind to the female structures on other plants.

It is important for the Dwarf Japanese Cedar to have male and female plants in close proximity to ensure successful pollination. Cross-pollination between two different plants is also beneficial for genetic diversity and the production of viable seeds.

The Dwarf Japanese Cedar is not dependent on insect pollinators, making it a low-maintenance plant in terms of pollination.

Overall, the Dwarf Japanese Cedar is a hardy tree that requires little attention to pollination, as it primarily relies on wind dispersal.

Frequently Asked Questions about Dwarf Japanese Cedar (Cryptomeria japonica 'Globosa Nana')

What is a Dwarf Japanese Cedar?

A Dwarf Japanese Cedar, also known as Cryptomeria japonica 'Globosa Nana', is a slow-growing, low-maintenance evergreen tree that typically grows up to 6 feet tall and wide with a conical shape. It is also commonly referred to as a Globe Japanese Cedar due to its spherical shape.

What are the ideal growing conditions for a Dwarf Japanese Cedar?

These trees typically grow best in full sun or partial shade and well-drained soil. They also prefer a slightly acidic soil with a pH range of 5.5 to 6.5. Avoid planting in areas with excessive moisture or standing water.

How often should a Dwarf Japanese Cedar be watered?

Dwarf Japanese Cedars do not require frequent watering and are actually quite drought-tolerant once established. However, it is important to ensure the soil is moist but not waterlogged during the growing season.

When is the best time to prune a Dwarf Japanese Cedar?

The best time to prune a Dwarf Japanese Cedar is in early spring before new growth appears. It is important to not remove more than one-third of the tree's foliage at one time. It is also recommended to not prune beyond the green foliage as this will not regrow.

How fast does a Dwarf Japanese Cedar grow?

Dwarf Japanese Cedars are slow-growing trees, typically growing 3 to 6 inches per year depending on growing conditions. However, they can live up to 50 years or more with proper care.

Can a Dwarf Japanese Cedar be grown in a container?

Yes, Dwarf Japanese Cedars can be grown successfully in containers. It is important to ensure the container has drainage holes and the soil is well-draining. It is also recommended to fertilize the tree twice a year with a slow-release fertilizer specifically designed for container plants.

What are the common pests and diseases that affect Dwarf Japanese Cedars?

The most common pests that affect Dwarf Japanese Cedars are spider mites and scale insects. These can be treated with insecticidal soap or horticultural oil. The most common diseases are root rot and cedar apple rust, which can be prevented by providing proper soil drainage and avoiding planting near susceptible apple trees.

Are Dwarf Japanese Cedars deer-resistant?

Yes, Dwarf Japanese Cedars are typically considered deer-resistant due to their prickly foliage. However, if food is scarce, deer may still browse on the tree.

Planting Instructions for Dwarf Japanese Cedar:

• Choose a location with well-draining soil and partial shade.
• Dig a hole twice the size of the container the plant came in.
• Gently remove the plant from the container and loosen the roots.
• Place the plant in the hole and backfill with soil, tamping down gently as you go.
• Water thoroughly after planting.

Care Instructions for Dwarf Japanese Cedar:

• Water regularly, keeping the soil consistently moist but not waterlogged.
• Fertilize in the spring with a slow-release, balanced fertilizer.
• Prune in early summer to maintain shape and size.
• Protect from harsh winter winds and heavy snowfall.
• Monitor for pest and disease problems, treating promptly if necessary.
