How to Pollinate Empress tree

(Paulownia tomentosa)

Empress tree, also known as Foxglove tree

The empress tree's pollination is a dance between nature and the tree itself, attracting industrious bees as its main pollinators with aromatic, tubular flowers. By releasing pollen via a shake-and-catch mechanism in synchronous timing with bee activity, the empress tree ensures pollination. Its pollination further syncs with the rhythm of seasons, peaking during its spring bloom period.

How Does Pollination Occur in Empress Tree?

Empress tree's flowers are purple-violet, bell-shaped, and arranged in large, showy panicles. They have a tubular corolla, divided into lobes, notable for attracting various pollinating agents.

Empress tree's pollination occurs primarily via insects, which collect nectar and transport pollen from the male to the female parts of flowers.

How Can You Enhance the Pollination of Empress Tree?

Plant Diversity

Incorporate flowering plants with different colors, sizes, and blooming periods in the garden or farm. This will help to attract and support a diverse range of pollinators including bees, moths, and beetles throughout the year.

Nesting Sites

Provide sites for the pollinators to nest and reproduce. Bees require undisturbed bare ground or dead wood to create nests, while beetles and moths need leaf litter and decomposing wood.

Night Lighting

As moths are nocturnal and are often drawn to light, installing UV or white ligths in the vicinity of the Empress tree may help attract them and improve pollination. However, care should be taken not to use excessive light which could disrupt local ecosystems.

Pesticides

Reduce the use of chemical pesticides on crops and replace them with organic or integrated pest management methods. This will minimize harm to bees, beetles and moths, and other beneficial insects. Always follow label instructions when using pesticides to minimize their impact on non-target species.

How Can You Determine if Empress Tree has Been Pollinated?

Flower Transformation

For empress tree, successful pollination is usually identified by a shift in the flower's color and structure as it progresses from fertilization to fruit set. This change signifies that pollination has occurred.

Fruit Formulation

After successful pollination in empress tree, the base of the flower starts thickening and developing into a fruit under ideal conditions, indicating that pollination has taken place.

Pollen Disappearance

Successful pollination in empress tree might be evidenced by a decrease in visible pollen on the plant's flowers, indicating that the pollen has been successfully transported to the plant's stigmas.

What Tools are Necessary for Hand-Pollinating Empress Tree?

Small Brush

A small, soft brush can be used to transfer pollen from the male flower to the female flower.

Handheld Magnifier

This helps with seeing small flower parts so you can locate the pollen and stigma more easily.

Marker and Labels

These are used for marking and recording the hand-pollinated flowers.

What is the Optimal Time for Hand-Pollinating Empress Tree?

The best time window for hand pollination of empress tree is early in the morning when the flowers open and when the temperature is mild. Also, it's best to do it when blooming period which is typically in the spring.

Steps to Hand-Pollinate Empress Tree

Step1: Preparation

Collect your materials and locate the flowers that are ready for pollination. These will often be ones that have just opened.

Step2: Accessing Pollen

With the help of a small brush, gently swipe the anthers of the male flower to gather the pollen. Care must be taken to not cause any damage to the plant parts.

Step3: Transferring Pollen

Once the pollen is gathered, it needs to be transferred to the female flower. Locate the stigma of the female flower and gently glide your brush over it.

Step4: Labeling

Post pollination, label the pollinated flower with a marker and labels, this step will help during the post germination period to identify the cross-pollinated plants.

Step5: Observation

Monitor the flowers for a few days to ensure pollination has been successful. A successfully pollinated flower will begin developing into a fruit.

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

Low Pollen Supply

If pollination is not occurring in empress tree, it could be due to a lack of pollen. Increasing the amount of flowering plants around it can attract more pollinators and increase pollination.

Pollen Sterility

Sterility of the pollen could cause issues in pollination for empress tree. Sterility can be caused by various factors such as diseases or sudden temperature shifts. Maintaining healthy plant conditions is crucial.

Inadequate Pollinators

Lack of sufficient pollinators can be a common problem in the pollination process of empress tree. Encouraging pollinator-friendly habitats by planting a variety of native plants can help attract more pollinators.
