Lonicera maackii thrives with at least four to six hours of sun each day because this species naturally grows in open woodlands with access to sunlight.

While it prefers full sun, partial sun is tolerated well. Ensuring filtered sunlight can help protect against overly intense rays, which can be managed by strategic planting near taller trees.

Amur honeysuckle (Lonicera maackii)

Also known as: Late honeysuckle

Amur honeysuckle (Lonicera maackii) is a perennial shrub with dense branching, dark green foliage, fragrant white flowers, and attractive red berries enjoyed by birds, which help disperse its seeds. Originally from East Asia, it was once popular for landscaping, wildlife habitat, and erosion control. However, its invasive tendencies have led to it being discouraged for planting. It aggressively outcompetes native vegetation, forming thick canopies that block sunlight, reducing native plant diversity and altering local ecosystems.

What Is the Ideal Temperature Range for Amur honeysuckle?

Ideal Temperature: 60 ~ 75℉

Lonicera maackii thrives best within a temperature range of 60°F to 75°F. This range supports healthy growth and flowering because it simulates the mild, temperate climate conditions to which this species is naturally adapted.

What Soil is Best for Amur honeysuckle?

Soil type: Loam, Sandy loam, Clay soil

Soil PH: 6.5 ~ 7.5

Lonicera maackii thrives in well-drained soil that allows water to flow through effortlessly, preventing root rot and encouraging robust growth by ensuring roots are not waterlogged. A soil rich in organic matter is essential for Lonicera maackii, providing the necessary nutrients for lush foliage and vibrant blooms. This can be achieved by incorporating compost or well-aged manure. While good drainage is key, the soil should also have some moisture-retaining properties to keep the roots hydrated without becoming soggy, balancing the plant's need for both air and water.

How to Fertilize Amur honeysuckle?

Fertilizer type: Balanced

For Lonicera maackii, the recommended fertilizer amount varies according to the plant's size. Generally, apply about 0.5 ounces of a balanced 10-10-10 fertilizer per foot of plant height. Avoid over-fertilization, as this can harm the plant.

How to Prune Amur honeysuckle?

Pruning Time: Spring, Autumn

Begin by removing any dead or diseased branches with sharp, clean pruners. Focus on thinning out dense areas to improve air circulation and shape the plant. Aim to create a balanced, open structure that encourages healthy growth. Lonicera maackii can be quite invasive, so look for shoots that are growing outward aggressively. Trim these back to maintain its size and prevent it from overtaking garden spaces. Always cut just above a leaf node to promote new growth.

How to Propagate Amur honeysuckle plant?

Propagate Time: Early spring, Late spring

Collect seeds from ripe Lonicera maackii berries in late autumn. Ensure they are free from debris and viable for better germination results.

Take semi-hardwood cuttings in early spring when the plant is actively growing. Each cutting should be approximately 6 inches long with several leaf nodes.

Stratify collected seeds by placing them in moist sand and keeping them refrigerated for about 90 days. This cold treatment breaks seed dormancy and promotes germination.

How to Repot Amur honeysuckle plant?

Repotting frequency: Every 2-3 years

Lonicera maackii, or Amur Honeysuckle, shows signs of needing repotting when roots start emerging through drainage holes or growth seems stunted. These indications typically appear every couple of years, especially if the plant is confined in a pot. Opt for spring or autumn to repot so the plant has optimal conditions to establish itself before extreme weather.

Select a pot that's only one size larger than the existing one; this prevents excess soil that can retain water and cause root rot. Materials like clay or terracotta are excellent as they allow better airflow to the roots, promoting healthier growth. Ensure the pot has sufficient drainage holes to prevent waterlogging.

The best soil for Amur Honeysuckle is one that is well-draining, such as a loamy mix. This type of soil retains enough moisture without becoming waterlogged, providing a balanced environment for the roots. Incorporate organic matter to improve nutrient content and structure, fostering robust growth.
