Honeyberry shrub propagation from cuttings

Introduction to Honeyberry Propagation

Honeyberries, also known as Haskaps or Blue Honeysuckle (Lonicera caerulea), are increasingly popular for their exceptionally nutritious and delicious fruit, early spring bloom, and remarkable hardiness. For gardeners looking to expand their honeyberry patch or share these fascinating plants with friends and family, propagation from cuttings is an accessible and rewarding method. This guide delves into the details of taking, rooting, and nurturing honeyberry cuttings to successfully grow new bushes. Propagating from cuttings allows you to create genetically identical clones of your parent plant, ensuring you maintain desirable traits like fruit flavor, yield, and disease resistance. It’s a cost-effective way to increase your honeyberry stock compared to purchasing new plants.

Understanding Honeyberry Cuttings: When and What to Take

Successful propagation hinges on selecting the right material at the opportune time. Honeyberries can be propagated from both softwood and hardwood cuttings, each with its own best practices.

Softwood Cuttings

Softwood cuttings are taken from new, actively growing shoots in late spring or early summer, typically when the stems are still flexible but have begun to firm up. These cuttings root relatively quickly but are also more susceptible to drying out.

• Timing: May through July is generally the prime time for softwood cuttings.
• Selection: Look for healthy, vigorous shoots that are at least 4-6 inches long. The current year’s growth should be firm enough that it snaps cleanly when bent, rather than kinking. Avoid any stems with flowers or developing fruit.
• Preparation:

Use sharp, sterilized pruning shears or a knife.
Take cuttings from the tip of a healthy shoot, making the cut just below a leaf node (the point where a leaf attaches to the stem).
Each cutting should have at least two to three leaf nodes.
Remove the lower leaves, leaving only the top two or three leaves. If the remaining leaves are very large, you can cut them in half horizontally to reduce transpiration (water loss).
Immediately place the cuttings in a plastic bag with a damp paper towel to keep them hydrated until you are ready to plant them.

Hardwood Cuttings

Hardwood cuttings are taken from mature, dormant wood during the fall or winter when the plant is not actively growing. These cuttings take longer to root but are generally more robust and less prone to drying out.

• Timing: Late autumn after leaf drop, or during the dormant season in winter, before new growth begins in spring.
• Selection: Choose healthy, well-matured branches from the current or previous year’s growth. The wood should be firm and woody, not green and flexible. Aim for stems that are pencil-thick or slightly thicker.
• Preparation:

Using sharp, sterilized pruning shears, cut sections of stem that are 6-8 inches long.
Make the bottom cut just below a leaf node.
Make the top cut just above a leaf node.
Bundle the cuttings together and store them in a cool, dark, and slightly moist environment (like a plastic bag with damp peat moss or sawdust in a refrigerator) until you are ready to plant them in early spring. This cool, moist storage can help break dormancy and encourage rooting.

The Propagation Process: Step-by-Step

Whether you choose softwood or hardwood cuttings, the fundamental steps to encourage rooting are similar, with slight variations in timing and treatment.

Step 1: Preparing Your Cuttings

This is a critical stage that directly influences success.

• For Softwood Cuttings:

Once you have taken your cuttings, immediately strip off the lower leaves.
If the remaining leaves are large, cut them in half to reduce water loss through transpiration.
Optional: Dip the cut end of the stem into rooting hormone. This powdered or liquid substance contains auxins, which stimulate root development. Ensure the hormone is suitable for softwood cuttings.

• For Hardwood Cuttings:

After overwintering (if stored), inspect your cuttings for any signs of rot or mold. Discard any unhealthy ones.
Optional: Dip the cut end into rooting hormone, specifically formulated for hardwood cuttings.

Step 2: Choosing Your Growing Medium

A well-draining and aerated medium is essential for preventing rot and promoting root growth.

• Ideal Mixes:

A 50/50 blend of perlite and peat moss or coco coir.
A mix of coarse sand and peat moss.
Specialized seed starting or propagation mixes.

• Key Properties: The medium should retain moisture but drain freely. It should also be sterile to prevent fungal diseases.

Step 3: Planting the Cuttings

The method of planting depends on whether you are rooting softwood or hardwood cuttings.

• Softwood Cuttings:

Fill small pots or a propagation tray with your chosen moist growing medium.
Gently insert the prepared cuttings into the medium, ensuring the lowest leaf node is buried.
Space the cuttings an inch or two apart to allow for air circulation.
Water gently to settle the medium around the cuttings.

• Hardwood Cuttings:

In early spring, plant the hardwood cuttings directly into a prepared garden bed or into large pots filled with your growing medium.
Plant the cuttings vertically, burying about two-thirds of their length. Ensure at least one or two leaf nodes are below the soil surface.
Space them about 6 inches apart to give them room to develop roots.
Water thoroughly.

Step 4: Creating the Right Environment

This is arguably the most crucial step for successful rooting. Honeyberry cuttings, especially softwood ones, require a consistently moist, humid environment with good air circulation.

• For Softwood Cuttings:

Humidity Dome: Cover the pots or tray with a clear plastic bag, dome, or lid to create a humid microclimate. Ensure the plastic doesn’t touch the leaves excessively.
Warmth: Place the propagation setup in a warm location, ideally with bottom heat (a heat mat can be beneficial, maintaining soil temperatures around 70-75°F or 21-24°C).
Light: Provide bright, indirect light. Avoid direct sunlight, which can scorch the young cuttings and overheat the humid environment.
Watering: Keep the medium consistently moist but not waterlogged. Mist the cuttings and the inside of the humidity cover regularly if the medium appears dry.

• For Hardwood Cuttings:

Location: Planted directly outdoors, they benefit from consistent moisture. If potted, place them in a sheltered location, perhaps a cold frame or unheated greenhouse, providing protection from extreme weather.
Moisture: Ensure the soil remains moist throughout the spring as they begin to root.
Light: They can tolerate more direct sunlight as they are dormant.

Step 5: Monitoring for Rooting and Aftercare

Patience is key. Rooting can take several weeks to months.

• Checking for Roots: Gently tug on a cutting. If there is resistance, it has likely developed roots. For softwood cuttings, you may also see new leaf growth.
• Acclimatization (Softwood Cuttings): Once roots have formed and new growth is evident, gradually acclimate the cuttings to lower humidity. Start by opening the humidity cover for a few hours each day.
• Transplanting: Once the cuttings have a well-developed root system and are growing actively, they can be transplanted into individual, slightly larger pots (e.g., 4-inch pots) with a good quality potting mix. Continue to provide consistent moisture and indirect light.
• Hardening Off: Before planting young honeyberry plants outdoors, gradually acclimate them to outdoor conditions over a week or two. This process, known as hardening off, involves exposing them to increasing amounts of direct sunlight, wind, and cooler temperatures.
• Planting Outdoors: Plant the hardened-off young bushes in their permanent location in the garden after the last frost. Ensure they are planted in well-draining soil with plenty of sunlight and have adequate spacing for mature growth. Honeyberries generally require cross-pollination from a different variety to produce fruit, so planting at least two different cultivars is recommended.

Pros and Cons of Honeyberry Cutting Propagation

Every propagation method has its advantages and disadvantages. Understanding these can help you choose the best approach for your circumstances.

Troubleshooting Common Propagation Issues

Even with careful attention, some cuttings may fail to root or succumb to problems. Identifying common issues can help you adjust your techniques.

Wilting and Browning

• Cause: Insufficient humidity, roots drying out, or damping-off disease.
• Solution: Increase humidity by ensuring the plastic cover is sealed. Check the moisture level of the medium. Ensure good air circulation to prevent fungal growth.

Rotting at the Base

• Cause: Overwatering, poor drainage, or fungal infection.
• Solution: Use a well-draining medium. Water only when the top inch of the medium feels dry. Ensure good air circulation. Sterilize your tools and media to prevent disease.

No Root Development

• Cause: Cuttings taken too early or too late, insufficient warmth, lack of rooting hormone, or poor quality parent material.
• Solution: Ensure you are taking cuttings at the correct maturity stage. Provide adequate bottom heat. Consider using a rooting hormone. Select healthy parent plants for your cuttings.

Beyond Cuttings: Other Honeyberry Propagation Methods

While cuttings are a popular and effective method, honeyberries can also be propagated by other means.

Layering

• Description: This involves encouraging roots to form on a stem while it is still attached to the parent plant.
• Method: Bend a healthy, flexible low-growing stem down to the ground. Make a shallow incision or scrape on the underside of the stem where it will contact the soil. Bury this section of the stem in the soil, leaving the tip exposed. Secure it with a stake or rock. Once roots have formed (usually after a year), the layered stem can be carefully cut from the parent plant and transplanted.

Division

• Description: Honeyberries, like many shrubs, can form suckers or new shoots from their base.
• Method: In early spring or fall, carefully dig around the base of a mature honeyberry plant. Identify clumps of suckers with their own root systems. Using a sharp spade or pruning saw, carefully divide the plant, ensuring each division has sufficient roots and shoots. Replant the divisions immediately.

Conclusion

Propagating honeyberry shrubs from cuttings is a fulfilling and economical way to expand your garden or share these nutritious berries. By understanding the best times to take softwood and hardwood cuttings, preparing them correctly, and providing the optimal growing conditions – particularly consistent moisture and high humidity for softwood cuttings – you can achieve excellent success rates. Remember to use sterile equipment, a well-draining medium, and be patient as your new honeyberry plants develop. With a little care and attention, you’ll soon have a thriving collection of these delightful and hardy berry bushes.
