Propagation by Softwood Cuttings

Softwood cuttings are one of the most common and effective methods for propagating plum trees, particularly during late spring to early summer when the new growth is still flexible. This method involves taking young, tender shoots that have not yet hardened off.

Select healthy, disease-free shoots about 6 to 8 inches long. Cut just below a node, which is where leaves attach to the stem. Remove the lower leaves, leaving only a few at the top to reduce water loss. To encourage root development, dip the cut end in a rooting hormone powder or gel.

Plant the cutting into a well-draining medium, such as a mixture of perlite and peat moss or a sandy soil mix. Maintain a humid environment by covering the container with a plastic bag or placing it in a mist propagation bench. Keep the medium moist but not waterlogged, and place the cuttings in a warm, bright location with indirect sunlight.

Rooting usually takes between 4 to 8 weeks. Once roots have developed, gradually acclimate the new plants to outdoor conditions before transplanting into larger containers or the garden.

Propagation by Hardwood Cuttings

Hardwood cuttings are taken during the dormant season, typically late autumn through early winter. This method is ideal for plum varieties that are more difficult to propagate from softwood cuttings.

Select mature, healthy wood about pencil thickness and 8 to 12 inches long. Cut just below a bud at the base and trim the top just above a bud. Remove any damaged bark or leaves. Before planting, it is beneficial to soak the cuttings in water for 24 hours to improve hydration.

Plant the cuttings vertically, with about two-thirds of their length buried in a well-draining, fertile soil mix. The soil should be kept moist but not saturated throughout the winter. Mulching the surface helps maintain consistent moisture and temperature.

Root development may take several months, and shoots should emerge in early spring. After shoots appear, gradually expose the new plants to outdoor conditions and transplant as necessary.

Propagation by Grafting

Grafting is a preferred method for propagating plum trees, especially to preserve the characteristics of a specific cultivar. It involves joining a scion (a young shoot or bud from the desired plum variety) to a compatible rootstock.

Common grafting techniques for plums include:

  • Whip and tongue grafting: Suitable in early spring before bud break. Provides a strong union due to interlocking cuts.
  • Cleft grafting: Used when the rootstock is larger than the scion, typically in early spring.
  • Budding (T-budding): Performed in summer when the bark is slipping, involving inserting a single bud under the bark of the rootstock.

Successful grafting requires clean, sharp cuts and close contact between the cambium layers of scion and rootstock. Secure the graft union with grafting tape or rubber bands and protect it with grafting wax or sealant to prevent desiccation and infection.

Propagation by Seed

While plums can be grown from seed, this method is less common for propagation because it does not guarantee that the offspring will retain the characteristics of the parent tree. However, seed propagation is useful for rootstock production or breeding new varieties.

To propagate plum trees from seed:

  • Extract seeds from fully ripe fruit and clean off all pulp.
  • Stratify seeds by placing them in moist sand or peat moss inside a sealed plastic bag and refrigerate for 8 to 12 weeks to break dormancy.
  • After stratification, plant seeds in a well-draining seed-starting mix about 1 to 2 inches deep.
  • Maintain consistent moisture and a temperature around 65-75°F (18-24°C).
  • Germination can take several weeks to a few months.

Seedlings should be grown in containers until large enough to transplant outdoors. Note that seed-propagated trees may take longer to bear fruit and can show variable fruit quality.

Comparison of Propagation Methods

Propagation Method Time of Year Advantages Disadvantages Typical Rooting/Growth Time
Softwood Cuttings Late spring to early summer Fast rooting, high success rate, preserves cultivar traits Requires humidity control, cuttings are delicate 4 to 8 weeks
Hardwood Cuttings Late autumn to early winter Simple technique, cuttings are sturdy Longer rooting time, lower success rate than softwood Several months
Grafting Early spring or summer (for budding) Maintains cultivar traits, strong rootstock compatibility Requires skill, precise timing Weeks to months for union to heal
Seed Propagation Any, after stratification Useful for rootstock, genetic diversity Variable traits, long juvenile period Weeks to months for germination, years to fruiting

Choosing the Right Method for Propagating Plum Trees

Plum trees can be propagated through several methods, each with its own advantages depending on the desired outcome and available resources. The primary methods include:

  • Grafting: Combining a desired plum variety (scion) onto a rootstock to produce a tree with specific characteristics.
  • Cuttings: Rooting hardwood or softwood cuttings to create genetically identical plants.
  • Layering: Encouraging root development on a branch while still attached to the parent tree.
  • Seed Propagation: Growing plum trees from seeds, though this method often results in variable fruit quality.
Propagation Method Time to Fruit Success Rate Genetic Uniformity Skill Level Required
Grafting 2-3 years High True to parent Moderate to High
Cuttings 3-5 years Moderate True to parent Moderate
Layering 3-4 years Moderate to High True to parent Low to Moderate
Seed Propagation 5-7 years Variable Variable Low

Grafting Plum Trees

Grafting is the preferred method for propagating plum trees when the goal is to preserve specific fruit qualities and tree characteristics. The process involves joining a scion, which is a cutting from a desired plum variety, onto a compatible rootstock. This union facilitates faster fruiting and greater disease resistance.

Steps for successful grafting:

  • Select rootstock: Choose a vigorous and disease-resistant rootstock suited to your soil and climate conditions.
  • Prepare scion wood: Collect healthy, dormant scion wood approximately pencil-thick, with several buds.
  • Perform grafting: Common techniques include whip-and-tongue grafting, cleft grafting, and budding.
  • Secure the graft union: Use grafting tape or parafilm to tightly bind the union and prevent desiccation.
  • Protect and care: Keep the grafted plant in a humid environment and avoid direct sunlight until the graft takes.

Grafting is typically conducted in late winter or early spring before sap flow begins. Monitoring for successful union formation involves checking for bud swell and new growth within several weeks.

Propagating Plum Trees from Cuttings

Rooting cuttings is a less complex propagation method that produces clones of the parent tree. For plum trees, hardwood cuttings taken during dormancy or semi-hardwood cuttings in late summer are most effective.

Procedure for rooting plum cuttings:

  • Cut selection: Choose healthy, disease-free stems about 6 to 12 inches long with several nodes.
  • Preparation: Trim the cutting so the bottom cut is just below a node and remove any leaves except for a few at the tip.
  • Rooting hormone: Dip the base of the cutting into rooting hormone powder or gel to stimulate root development.
  • Planting: Insert the cutting into a well-draining propagation medium such as a mixture of sand and peat moss or perlite.
  • Environment: Maintain high humidity using a propagation dome or plastic bag and keep the medium moist but not waterlogged.
  • Root development: Expect roots to form within 6 to 12 weeks; gentle tugging can test root firmness.

Once established, gradually acclimate the new plants to outdoor conditions before transplanting into the ground or larger containers.

Layering Techniques for Plum Tree Propagation

Layering is a natural method that encourages root growth on a low-hanging branch while still attached to the parent tree. This method is particularly useful when grafting or cuttings are not feasible.

Steps for ground layering:

  • Select a flexible branch: Choose a healthy, low-hanging branch that can be bent to the ground easily.
  • Wound the branch: Make a shallow cut or remove a ring of bark on the underside of the branch to expose the cambium layer.
  • Apply rooting hormone: Optionally dust the wounded area with rooting hormone to encourage root formation.
  • Secure branch in soil: Bend the branch down to the soil surface and cover the wounded section with soil, leaving the tip exposed.
  • Anchor the branch: Use a peg or stone to hold

    Expert Insights on How To Propagate Plum Trees
