Blackberry Cuttings Fail and What I Do Instead

I have tried blackberry cuttings several times and have not had any success with them.  I can easily propagate with root cuttings, harvesting the suckers, tip and serpentine layering but cane cuttings has proven difficult.  Note, I have not tried using the rooting hormone for the cuttings so maybe that is why but research says you can do it without the rooting hormone.  I recently did an experiment on stem cuttings trying both primocanes and floricanes along with scratching and no scratching to promote rooting.  Neither worked.  It's difficult to keep the right moisture levels.  I've also tried using a lot of moisture and less moisture along with keeping the cuttings inside and outside in the shade.  Still no growth.  I don't want to use a rooting hormone so I'll stick with root cuttings, harvesting the suckers, tip and serpentine layering which I find the easiest.  Check out my experiment below in video format.  



If you still want to try root cuttings then you can follow the steps below:  

Propagating Blackberries from Root Cuttings: A Step-by-Step Guide

Blackberries are a delicious and versatile fruit that can be enjoyed fresh, in pies, jams, jellies, and more. Growing your own blackberries allows you to harvest fresh berries at peak ripeness, and propagating them from root cuttings is an easy and cost-effective way to expand your garden. Here's a comprehensive guide to help you get started.

Why Propagate Blackberries from Root Cuttings?

Propagating blackberries from root cuttings has several advantages:

  • Cost-effective: You can create new plants without purchasing additional ones.
  • Genetic consistency: New plants will be identical to the parent plant, ensuring consistent fruit quality.
  • Simplicity: The process is straightforward and doesn't require specialized equipment.

Types of Cuttings

Blackberries can be propagated from both softwood and hardwood cuttings:

  • Softwood Cuttings: Taken from fresh, new growth in early summer. They root quickly, usually within 3-6 weeks, but have a lower success rate compared to hardwood cuttings.
  • Hardwood Cuttings: Taken from mature, dormant stems in late fall or winter. They require 8-12 weeks of cool weather to root but have a higher success rate.

When to Take Cuttings

  • Softwood Cuttings: Best taken in early summer when new growth has hardened off but is still pliable. Ideal conditions include night temperatures above 55°F and avoiding hot, dry weather.
  • Hardwood Cuttings: Collected after plants become dormant, typically after several hard frosts in cold areas or late fall through winter in milder climates.

Preparing the Cuttings

  1. Select Healthy Stems: Choose disease-free stems. For softwood cuttings, select green, flexible shoots. For hardwood cuttings, choose woody stems that have lost their leaves.
  2. Cut the Stems: For softwood cuttings, cut 4-6 inch sections. For hardwood cuttings, cut 6-8 inch sections.
  3. Remove Lower Leaves: Strip the leaves from the lower half of the cutting to prevent rot.
  4. Optional: Apply Rooting Hormone: Dip the cut end in rooting hormone to encourage faster root development.

Planting the Cuttings

  1. Prepare the Potting Mix: Use a mix of peat moss and sand or perlite for good drainage.
  2. Plant the Cuttings: Insert the cuttings into the potting mix, ensuring at least one node is buried.
  3. Maintain Humidity: Cover the cuttings with a plastic dome or bag to maintain high humidity.
  4. Provide Bottom Heat: If possible, use a heating mat to keep the soil temperature around 70°F to encourage rooting.

Caring for the Cuttings

  • Light: Place the cuttings in a location with low to moderate light. Avoid direct sunlight.
  • Watering: Keep the soil moist but not waterlogged. Mist the cuttings periodically to maintain humidity.
  • Monitoring: Check for root development after a few weeks. Softwood cuttings typically root in 3-6 weeks, while hardwood cuttings may take 8-12 weeks.

Transplanting

Once the cuttings have developed a healthy root system, they can be transplanted into larger pots or directly into the garden. Ensure they are planted in well-drained soil and receive adequate sunlight.

By following these steps, you can successfully propagate blackberries from root cuttings and enjoy a bountiful harvest in your garden. Happy gardening!

Blackberry I Trellis Upgrade to Wire

Image
When I first started growing blackberries I created a very simple I trellis using garden string.  It worked very well for a single season but now that my blackberries are established it's time for an upgrade.  Check out my video below of upgrading my T-Post I trellis from string to 12 gauge wire.   How to Build an "I" Trellis: A Simple Guide for Your Garden An "I" trellis is a straightforward and effective structure that provides support for climbing plants like beans, peas, cucumbers, and flowering vines. Building your own "I" trellis is a cost-effective way to enhance your garden's productivity and aesthetics. Here’s a step-by-step guide to help you create an "I" trellis. Materials Needed Two sturdy wooden posts (6-8 feet tall) Crossbeam (a wooden board or metal rod) Galvanized screws or nails Drill or hammer Measuring tape Level Posthole digger or shovel Concrete mix (optional) Twine or wire Step-by-Step Instructions Choose the Locat...

Grow a Peach Tree From Seed

All the research I’d done for growing a peach tree from seed said you had to do a few months of cold stratification in order for the seed to germinate. You can fast track this process that goes from seed germination to a pot in 14 days. Here’s my journey for growing a peach tree from a store bought peach!

5 Steps After Blackberry Season Ends

Image
  Here are 5 things I do at the end of the season after the blackberry harvest. 1. Prune the floricanes. 2. Tip the canes to encourage laterals. 3. Add compost/fertilizer. 4. Cane management - attach to trellis. 5. Blackberry propagation - Tip Layering.   More information:   As blackberry season comes to an end, it’s important to properly handle the remaining harvest and prepare for next season. Here are some tips to make the most of the end of blackberry season: 1. Harvest Remaining Fruit: Pick ripe berries: Blackberries should be fully ripe before harvesting, as they don’t ripen after being picked. Look for deep black color and ease of detachment from the plant. Pick regularly: Try to pick every few days to prevent overripe or spoiled fruit from falling on the ground. Handle gently: Blackberries are delicate and can bruise easily, so handle them with care while picking. 2. Preserve Excess Berries: Freeze them: If you have more berries than you can u...
