How to Pollinate Southern dewberry

(Rubus trivialis)

Southern dewberry, also known as Southern dewberry

The enchanting southern dewberry entices bees, its primary pollinators, with delightful scents and vibrant colors. Its efficient pollination mechanism relies on the diligent work of these bees, who individually transfer pollen from stamen to stigma. The beautiful symphony of southern dewberry pollination typically blossoms during the warm days, promising a bountiful neon green appeal.

How Does Pollination Occur in Southern Dewberry?

The flower of southern dewberry is a 'single type', with five bright white petals surrounding a central cone of small stamens and pistils. It's hermaphroditic (self-fertile), bearing both the anthers and a style, facilitating pollination.

Southern dewberry is largely pollinated via entomophily — pollination by insects that are attracted to its brightly colored petals and nectar.

How Can You Enhance the Pollination of Southern Dewberry?

Planting Diversely

Increase plant diversity by incorporating a wide range of flowering plants in the garden or farm. This would attract a wider range of pollinators, including bees and butterflies, as different pollinators are attracted to different types of plants.

Water Provision

Establish a water source in the garden or farm. Bees and butterflies, like most animals, need a fresh water source to survive. Small ponds, birdbaths or even shallow dishes of water can serve as reliable sources of water for these pollinators.

Reducing Pesticide Use

Minimize the usage of pesticides, particularly during the plants' flowering period, to prevent harm to the bees and butterflies. If pest control is necessary, consider adopting organic methods or utilizing integrated pest management strategies.

Bee-friendly Plants

Plant more bee-attracting plants such as lavender, cosmos, and sunflowers. These would not only beautify the surrounding, but also help to attract and provide nectar to the bees.

How Can You Determine if Southern Dewberry has Been Pollinated?

Flower Activity

Regular visitation from bees or other pollinators on southern dewberry indicates a high chance of successful pollination.

Fruit Formation

After successful pollination in southern dewberry, small green berries will begin to form and gradually ripen to black.

Pollen Dispersal

A powdery yellow substance on the inner parts of southern dewberry's flowers or on insect bodies indicates active pollen dispersal.

What Tools are Necessary for Hand-Pollinating Southern Dewberry?

Small Brush

To manually transfer pollen from the anther (male part) to the stigma (female part) of a southern dewberry flower.

Magnifying Glass

To better identify the reproductive parts of the southern dewberry flower, especially if they are small or indistinct.

Cotton Swab

As an alternative to a small brush, to pick up pollen from the anther and deposit it on the stigma.

What is the Optimal Time for Hand-Pollinating Southern Dewberry?

Hand pollination in southern dewberry is most effective during the mid-morning hours. Additionally, this should be performed during the peak blooming period of the southern dewberry, typically early to late spring, when the flowers are fully open.

Steps to Hand-Pollinate Southern Dewberry

Step1: Preparation

Place all your required tools in a comfortable, easy-to-reach setup next to your southern dewberry plants’ blooming area.

Step2: Identify Ready Flowers

Using a magnifying glass if necessary, identify flowers that are mature, fully open, and ready to be pollinated.

Step3: Collect Pollen

Use the small brush or cotton swab to gently swipe over the anthers of the southern dewberry flower to collect pollen.

Step4: Transfer Pollen

Gently brush the collected pollen onto the stigma of the same or another southern dewberry flower. Be careful not to damage the stigma.

Step5: Repeat Process

Continue this pollination process for all the mature flowers on the southern dewberry plant., taking care not to mix pollen from different flowers.

Step6: Cleanup

Clean your tools thoroughly after the process or when moving on to another plant to avoid cross pollination.

Why Aren't There Fruits on Southern Dewberry Despite the Presence of Flowers?

Low Pollinator Activity

If southern dewberry experiences shortages of natural pollinators, encourage them by planting diverse flowering species nearby or consider hand pollinating.

Poor Berry Development

If berries aren't forming or ripening on southern dewberry, ensure the plant is getting sufficient water and sunlight, and isn't overcrowded by other plants.

Pest Damage

If pests are damaging the flowers of southern dewberry, use eco-friendly pesticides or introduce beneficial insects to the environment.
