How to Plant, Grow, and Care for Honeyberry Shrubs
Destined to be the next superfruit, honeyberries look like elongated blueberries with a similar taste. In this article, gardening expert Wendy Moulton looks at how to grow and care for these special plants.
Contents
Known as the edible honeysuckle, honeyberry shrubs are cold-hardy and easy to grow and maintain. They flower in winter when most other plants are dormant, and the creamy, tubular flowers have a lovely honeysuckle fragrance.
They taste similar to blueberries, but with raspberry and blackberry undertones. This unique fruit is a member of the honeysuckle family and is easy to grow with few pests and diseases. The fruit appears in spring and is very high in antioxidants and other beneficial nutrients.
Honeyberry is a good ornamental plant and an edible for the food garden. With very little care but for annual feeding and pruning after a few years, they will perform well for many years to come. Read on for more about this great perennial.

What Is It?
Lonicera caerulea is a member of the honeysuckle family and has various common names, including haskap (from Japan), zhimolost (from Russia), blue honeysuckle, and honeyberry. The Russian and Japanese varieties have some subtle differences.
Honeyberry is a tough, deciduous shrub that is winter-hardy and produces a fruit crop in early spring.
Native Area
Honeyberry (Lonicera caerulea) has origins in the temperate regions of most of Europe, Asia, and parts of the US, including an area from California to Wyoming and north into Canada. Several hybrids have been bred, many Russian and some from Canada.
Characteristics
Honeyberry shrubs grow 4-6 feet tall and have a girth of about the same size, but they can be pruned to keep them more compact. There are also compact varieties to choose from.
The flowers are a creamy yellow color, and a tubular shape, and appear in late spring and early summer. They also have the wonderful honeysuckle fragrance that permeates the air, especially at night.
The fruits are used for jams, jellies, juices, and wine. They are great for eating fresh and melt in your mouth with their rich, unique berry flavor. They also make a unique sweet sauce for ice cream and cakes. To preserve them, they can be frozen but will burst through their skins when they defrost – good for winemakers, not so good for eating fresh. Honeyberries are also pickled and dried.
One reason honeyberries are grown is their health benefits. They are rich in antioxidants, vitamin C, and vitamin B, as well as iron, calcium, phosphorous, and especially magnesium.
These shrubs are not self-pollinating and require another variety to help pollinate the flowers. Before planting, ensure you have enough space for at least two shrubs.
These extremely hardy shrubs can fruit for up to 30 years or more once you have them planted and look after them with some annual care.
Planting
Ensure plenty of space between bushes, at least five feet, to account for their mature size. Choose a position with full sun or partial shade. They will grow to around six feet high when mature, but there are also compact varieties that are perfect for container growing and smaller gardens.
The best time to plant honeyberry bushes is spring, so they have time to acclimate to their soil and surroundings before the following season. Soak plants in water 30 minutes before planting to help release their roots from the nursery container. Dig a hole at least twice the width of the rootball. This will allow the roots to spread and secure the plant in the soil.
Add plenty of compost to the soil and mix well before using it to plant the shrub in the hole and backfilling. Press down to release air pockets, make a basin around the plant, and water well. Add a layer of organic mulch around the plant, making sure to keep the mulch off the plant’s stems.
How to Grow
Once you have a honeyberry shrub, you have one for a lifetime. Easy to grow and look after, honeyberry shrubs are a good addition to an edible garden and are ornamental, too.
Light
Plant in full sun for more berries, but some varieties will do okay in partial shade.
Water
In the first season, these shrubs prefer evenly moist soil. After that, they can survive with just rainwater and are relatively drought-tolerant. Watch for very dry and hot weather and give them supplementary water. When watering, water deeply to promote deeper root growth. Plants in containers need regular watering.
Soil
Honeyberries will need fertile, rich soil that is well-draining. Add plenty of compost when planting. Their preferred pH level is between 5.0 and 7.0.
Temperature
This cold-hardy plant can take temperatures up to -40°F (-40°C). The flowers are also frost-hardy and can withstand temperatures down to 20°F (-7°C). These plants need at least 800 – 1200 chill hours to set fruit at temperatures under 45°F (7°C).
Fertilizing
Feed them a balanced organic fertilizer in spring and top up or replace the mulch around the plants. However, be cautious when fertilizing, as the shallow roots will burn with too much fertilizer around them.
Maintenance
The bushes flower late spring or early summer, providing a nectar source for bees. However, because they are often grown in colder climates, it may be necessary to help the shrubs pollinate by using a paintbrush and hand-pollinating the flowers. This will ensure a good crop of fruit come spring.
Pruning
Prune honeyberry bushes in winter when dormant and before they start sprouting new growth. This should be just after you have harvested the last of the fruits.
In the first few years, honeyberry bushes will not require much pruning except to remove damaged growth. After that, an annual light pruning will make the shrubs bushier. First, cut away any crossing branches and weak growth. Second, reduce the growth by a third, cutting the branches back to an outward-facing bud. Open up the bush and keep it compact and in good shape. Any pruned branches will then thicken up and boost the plant to perform better the following season.
While pruning back the tree, take some hardwood cuttings to propagate more plants.
Harvesting
When the fruits are a deep blue color, they are ready to harvest. Wait until the fruit is ready before harvesting, as they will not ripen off once picked.
Propagation
Hardwood cuttings are the best way to propagate a honeyberry.
Prepare pots with a potting medium mixed with coarse sand and ensure plenty of drainage. Take cuttings from a healthy branch about a pencil thickness and cut the base near a bud at a 45° angle. Each cutting should be around 8 inches long with no leaves or other growth.
Dip the ends of the cuttings into hormone rooting powder and pop them into pre-made holes in the pots. You can plant about four to five in one pot. Keep the pots well watered and place them in a sheltered position away from cold, in a cold frame or greenhouse until the next season, when they will have sprouted and formed a good set of roots and can be planted. They will take about 12 months to grow into good-sized plants to grow on in the garden.
Growing from Seed
It is possible to grow honeyberries from seed. Remove all the flesh from around the seeds and sow in moist seedling or germinating mix in summer. Be patient. Your seeds will sprout in three to six weeks.
Popular Varieties
There are several varieties of honeyberry, each with its own characteristics. For the best results, choose the correct one for your particular area from a local grower.
‘Borealis’
A cold-hardy variety for zones 2-6 with large sweet berries that are best for fresh eating. A compatible pollinator plant would be ‘Tundra’ or ‘Honey Bee’.
‘Tundra’
A cold-hardy variety for zones 2-6. It has medium-sized fruit with a sweet but tart flavor. The best pollinators for this variety are ‘Borealis’ and ‘Indigo Gem’.
‘Honey Bee’
This variety is best in moderate climates for zones 3-7. It has medium-sized fruit with a sweet taste. The best pollinators for this variety are ‘Indigo Gem’, ‘Aurora’, and ‘Borealis’.
‘Indigo Gem’
A popular variety for moderate climates for zones 3-7 that produces an abundant crop of medium-sized sweet and tart fruit. Pollinators for this variety include ‘Honey Bee’ and ‘Tundra’.
‘Aurora’
A good variety for eating fresh with large sweet fruit. Pair this variety with ‘Honey Bee’ and ‘Indigo Gem’.
‘Cinderella’
Bridging the gap between moderate and warmer climates is this variety that has medium-sized berries with a tangy flavor. The best pollinators for this variety are ‘Blue Moon’ and ‘Blue Velvet’.
‘Berry Blue’
For zones 4-8, this berry has large, tart, and sweet fruit. The varieties ‘Blue Velvet’ and ‘Blue Moon’ are its preferred pollinators.
‘Blue Moon’
A more heat-tolerant variety for zones 4-8 with medium fruits that are flavorful. The pollinators for this variety include ‘Blue Velvet’ and ‘Cinderella’.
‘Blue Velvet’
A heat-tolerant variety for zones 4-8 that produces medium-sized fruit with a sweet taste. For pollination, pair with ‘Blue Moon’ or ‘Cinderella’.
Common Problems
These shrubs are relatively pest and disease free. However, you, the wildlife, and the birds will probably fight to see who gets to the fruit crop first. If this is a problem in your area, cover the plants with bird netting.
Powdery mildew can be an issue in overcrowded or overly moist plants. Use your annual pruning to open up the plant, remove any damaged branches, and prevent mildew from forming on unaffected branches.
Final Thoughts
Honeyberry bushes are excellent shrubs for the garden because of their honeysuckle flowers and the glorious fruit they produce. Some may say that they are even better and easier than growing blueberries. They have some of the same (even more) health benefits and grow and survive in very cold climates. I would pick up two just because they are easy to grow, and if you have the space, why not?
