How to Pollinate Laurustinus

(Viburnum tinus)

Laurustinus, also known as Laurustinus viburnum

Laurustinus sings its sweet pollination melody principally with bees as the thrumming maestros. These buzzing couriers are deftly enticed by the plant's aromatic blooms and the promise of nectar. They play a crucial role in laurustinus's mechanism of cross-pollination, transporting pollen from one flower's anther to another's stigma. The plant's floral fanfare takes place primarily in spring, setting the stage for the next generation of laurustinus.

How Does Pollination Occur in Laurustinus?

Laurustinus produces small, aromatic flowers grouped in dense and rounded clusters. Each individual flower is tubular, with five red-tinged petals spreading out from the center.

The flowers of laurustinus are entomophilous, meaning they are pollinated by insects. This plant also demonstrates a certain degree of self-pollination.

How Can You Enhance the Pollination of Laurustinus?

Plant Diversity

Having a diverse range of flowering plants in your garden or farm can attract a greater number of pollinators. For bees, butterflies, and moths, consider planting plants that bloom at different times of the year, ensuring there is always a food source available. Choose flowering plants with different colors, fragrances and shapes as each species of pollinator has unique preferences.

Provide Water Sources

Bees, butterflies, and moths need water for drinking. Provide shallow, clean water sources in your garden or on your farm. A bird bath, water feature, or even a shallow dish of water can serve as an effective water source. Add stones or twigs to the water to prevent the pollinators from drowning.

Less Pesticides

Pesticides can be harmful to pollinators such as bees, butterflies, and moths. Try to minimize the use of pesticides, especially during the plants' bloom times, when pollinator activity is at its peak. Instead, you could use organic pest control methods or an integrated pest management approach.

Pollinator Habitats

Building and preserving habitats for your primary and potential pollinators can provide a safe place to live, breed, and rest. Bees can benefit from bee hotels, while butterflies and moths may appreciate patches of native wildflowers, or piles of leaves and sticks. This also ensures that pollinators stay close to your plants, thus improving pollination.

How Can You Determine if Laurustinus has Been Pollinated?

Flower Coloration

Healthy pollination in laurustinus often results in a change in flower color, from white to pink, indicating the successful transfer of pollen.

Fruit Formation

If pollination is successful in laurustinus, it will result in the formation of blue or black fruits. Lack of fruit indicates unsuccessful pollination.

Pollen Presence

Visible pollen on the flower stigmas of laurustinus is a sign of successful pollination, indicating that pollinators are active.

What Tools are Necessary for Hand-Pollinating Laurustinus?

Small Brush

A small, soft brush can be used to transfer pollen from one flower to another.

Gloves

Wearing gloves can protect your hands and ensure the process is hygienic.

Ziploc Bags

These can be used to cover the flowers after pollination to prevent cross-contamination from other pollen sources.

What is the Optimal Time for Hand-Pollinating Laurustinus?

The best time to perform hand-pollination on laurustinus is in the early morning when the flowers are fully opened and the plant's pollen is most readily available. This typically coincides with the late winter or early spring when laurustinus blooms.

Steps to Hand-Pollinate Laurustinus

Step1: Preparation

Put on your gloves and get your brush ready for collecting pollen.

Step2: Collecting Pollen

Locate a flower with visible pollen in the center. This is usually a bright yellow color. Gently use the brush to collect pollen from the flower trying not to damage the petals.

Step3: Applying Pollen

Now locate another flower within the same plant (or another laurustinus if you wish to crossbreed) that looks fresh and undamaged. Carefully brush the pollen onto the stigma in the center of the other flower.

Step4: Securing Flower

Once you've applied the pollen, you can gently cover the pollinated flower with a ziploc bag., secured with a twist tie. This prevents other types of pollen from contaminating the flower.

Step5: Repetition

You should repeat this process daily over the period that the laurustinus is flowering to increase the chances of successful pollination.

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

Lack of Pollinators

In case of noticeable absence of pollinators, manually pollinate laurustinus by gently dusting a small paintbrush on the stigmas and stamens of the flowers.

Poor Fruit Set

For poor fruit set, consider applying a balanced liquid fertilizer during the blooming phase to enhance laurustinus's fertility.

Climate Conditions

Extreme weather conditions can hinder the pollination process in laurustinus. Ensure the plant is sheltered from harsh winds, heat, or cold.
