Before diving into the steps for growing blackberries from cuttings, it’s important to understand the basics. Blackberries are perennial plants, meaning they live for several years and produce fruit each season. There are different varieties of blackberries, including erect, semi-erect, and trailing, which have different growth habits and will influence how you manage the plants. Knowing the type of blackberry variety you wish to grow will help ensure success in your propagation endeavor.

Understanding the Basics of Blackberries and Cuttings

Blackberries are a popular fruit that many people enjoy. They grow on perennial plants, which means they come back year after year without having to replant them. One way to start growing blackberries is by using cuttings. This method provides an efficient, cost-effective way to propagate blackberry plants and enjoy their sweet, juicy fruits.

To begin, it’s essential to know which variety of blackberry you’d like to grow. There are both erect and trailing types, with some types producing fruit on first-year canes, while others only produce on second-year canes. By understanding these characteristics, you can select the ideal variety for your garden.

Once you’ve picked your variety, it’s time to obtain cuttings. Choose healthy plants with strong canes that are free from pests and diseases. The ideal cuttings come from young canes that are still green and flexible.

Next, consider the timing for starting your cuttings. The best time is during the dormant season, which is typically late winter or early spring. This allows the cuttings to establish themselves before the growing season kicks into gear. However, you can still propagate cuttings during the summer months if you keep them sufficiently moist.

To take your cuttings, prepare a clean, sharp pair of pruning shears. Cut a 4-6 inch section from the tip of a healthy cane. Remove any leaves or fruit from the cutting, and make sure there are at least two buds present. To enhance the success rate, you may consider using a rooting hormone to promote root growth.

Finally, prepare your planting site. Whether you use pots or plant directly in the ground, ensure there’s proper drainage to prevent root rot. Soak the lower end of the cutting in water before placing it in the soil with at least one bud buried, keeping the other bud above the surface. Keep the soil consistently moist and look for signs of new growth to signify successful propagation.

By understanding the basic principles of blackberries and cuttings, you can start growing these delicious fruits in your garden and enjoy the benefits they provide.

Materials Required

Planning and Preparation

Before you begin, it’s essential to plan and prepare for the project. Research different types of blackberry plants, and choose the variety that best suits your preferences and growing conditions.

Ensure that the area where you intend to plant the cuttings has proper drainage and a suitable spot for the plant to grow.

Gathering the Necessary Tools

To successfully grow blackberries from cuttings, you’ll need the following tools and materials:

  • Sharp, clean pruning shears: To harvest the cuttings without damaging them. Properly sanitized shears prevent the spread of diseases.
  • Well-draining potting mix: Provides optimal conditions for the cuttings to develop roots. A blend of peat moss, perlite, and compost is a good option.
  • Containers: Small pots or cell plug trays to hold the cuttings while they root. Ensure they have drainage holes to prevent root rot.
  • Rooting hormone: Helps the cuttings root faster and is optional, but recommended for higher success rates. It’s available in powder, liquid, or gel form.
  • Clean water: To keep the cuttings hydrated and to moisten the potting mix.
  • Clear plastic bags or a mini greenhouse: To create a humid environment for the cuttings while they establish roots.

With these tools and materials in place, you’ll be well-prepared to grow blackberries from cuttings. Following the proper technique and care will ensure a successful propagation and provide you with bountiful harvests for years to come.

Choosing and Preparing a Suitable Cutting


It is crucial to select the right time of year to take cuttings from blackberry plants. The ideal period to do this is during late winter or early spring, when the plants are still dormant but getting ready for new growth. This timing ensures that the cuttings have enough time to develop strong roots before the growing season begins.

Selecting Healthy Blackberry Canes

When choosing a cutting to propagate blackberry plants, you want to look for healthy, disease-free canes with no signs of insect damage. Ideally, select canes from a second-year plant – these are known as “floricanes.” These canes will have a woody appearance and should be about the thickness of a pencil. It’s essential to avoid canes from a first-year plant, known as “primocanes,” as they aren’t suitable for propagation.

To ensure the greatest chance of success, follow these guidelines when preparing your blackberry cutting:

  1. Choose the right portion of the cane: Aim for a section that is 4 to 6 inches long with at least two or three healthy buds. The buds are the small, dormant growth points where new leaves and branches will emerge.
  2. Make a clean, angled cut: Using sharp, sterile pruning shears, make a straight cut above a bud at the top of the chosen cutting. Then, make an angled cut at the base, about an inch below the bottom bud. The angled cut will help to distinguish the top from the bottom and increase the cutting’s surface area for better absorption of water and nutrients.
  3. Remove any leaves: Take off any remaining leaves from the cutting. Removing them will reduce the chances of disease transmission and lower the demand for water, allowing the cutting to focus on root development.
  4. Prepare the cutting for planting: Before planting the blackberry cutting, consider dipping the base into rooting hormone powder. This step is optional but can improve the cutting’s chances of developing a strong root system.

By following these guidelines and ensuring that you have chosen the appropriate timing and healthy blackberry canes, you will increase the likelihood of successfully propagating new blackberry plants from cuttings.

The Propagation Process

Preparing the Pot

Before starting the propagation process, it is essential to prepare a suitable pot for your blackberry cutting. Choose a container with drainage holes, to avoid waterlogged soil. Fill the pot with a sterile, well-draining potting mix like peat moss and perlite combination. Moisten the soil evenly, but do not overwater it.

Planting the Cutting

To propagate blackberries from cuttings, select a stem that is healthy and free from any diseases or pests. Pick a 6-8 inches long tip from this stem, ideally from the previous growing season. Remove all the lower leaves from the cutting, leaving only two or three at the top. If the stem has any flowers or buds, remove them as well.

Dip the bottom end of the cutting in rooting hormone, which encourages root growth. Create a hole in the prepared potting mix, around 2 inches deep, using a pencil or your finger. Gently place the cutting into the hole, making sure the hormone-covered end is completely buried. Cover the hole with soil, firming it around the cutting to prevent air pockets.

The Care and Nurture

Proper care is crucial for the successful propagation of blackberry cuttings. Place the potted cutting in a bright location, sheltered from direct sun, to allow for steady growth. Maintain a consistent temperature, between 65 and 75 degrees Fahrenheit, to promote root development.

Keep the potting mix moist, but not soggy, to avoid drowning the cutting or causing root rot. A light mist with a spray bottle is an excellent method to maintain adequate moisture levels. It can be helpful to cover the pot with a plastic bag or place it in a mini greenhouse. This step will increase the humidity around the cutting and promote quicker rooting.

Monitor the cutting’s progress by checking for signs of new growth, such as leaves or shoots, which indicate successful rooting. After a few weeks, give the stem a gentle tug to see if roots have formed. If the cutting has rooted and shows new growth, it can be transplanted into a larger pot or the garden. With the right care and attention, your blackberry cutting will grow into a fruitful bush, ready to produce delicious berries in future seasons.

Common Mistakes and Solutions

When trying to grow blackberries from cuttings, it is essential to avoid common mistakes to ensure success. Here are some frequently encountered issues and their solutions.

One common mistake is choosing the wrong type of cutting. It is crucial to select healthy and disease-free cuttings from the parent plant. The ideal cutting should be around 6-8 inches in length, with at least two leaf nodes. Make sure to take the cuttings during the dormant season, typically in late winter or early spring.

Over-watering the cuttings may lead to root rot. It is essential to water them moderately, maintaining consistent moisture in the soil. The right balance between moisture and air is critical; you can achieve this by placing the cutting in a well-draining soil mix and avoiding overly wet conditions.

Planting the cuttings too deep is another mistake to avoid. When planting, make sure the lowest leaf node is just below the soil surface. This placement ensures proper root development and growth.

Inadequate sunlight can also hinder the growth of blackberry cuttings. Blackberries require at least six hours of direct sunlight each day for optimum growth. Therefore, it is crucial to position the cuttings in a spot that receives sufficient natural light.

Ignoring diseases and pests can lead to significant damage to your blackberry plants. Keep an eye out for common issues such as fruit fly infestations and diseases like blackberry rust or anthracnose. Address any problems promptly by using organic pest control methods or treating them with appropriate fungicides.

Not providing adequate support is another mistake new growers often make. Blackberry plants need support as they grow, which can be provided by installing a trellis or wire framework. This support assists in avoiding tangled canes and promotes good air circulation, reducing the chances of disease.

Finally, skipping the hardening-off process might cause transplant shock, leading to poor growth. Gradually acclimate the cuttings to their new environment by slowly exposing them to the outdoors, increasing the duration and intensity of sunlight over a week or two.

By avoiding these common mistakes and applying the appropriate solutions, your blackberry cuttings will have a greater likelihood of growing into healthy, fruit-bearing plants.
