How to Pollinate Greater masterwort

(Astrantia major)

Greater masterwort, also known as Mountain sanicle

The captivating greater masterwort relies primarily on bees for its pollination. These buzzing friends are irresistibly drawn to its vivacious blooms filled with nectar, marking a marvelous pollinator attractant. The pollination mechanism involves the transfer of pollen from the stamen to the pistil, facilitated by the plant's intricate design. Synchronized with the bee's activity, pollination peaks during daylight hours, highlighting nature's immaculate timing.

How Does Pollination Occur in Greater Masterwort?

Greater masterwort's flowers are umbel-shaped inflorescences surrounded by a collar of bract-like petals, creating a characteristic star-like pattern. The true flowers are small, clustered in the center and are relevant in the pollination process.

Pollination in greater masterwort occurs when pollen is transferred from the anthers to the stigma, facilitated by wind or insect activity. Self-pollination is possible but cross-pollination predominates.

How Can You Enhance the Pollination of Greater Masterwort?

Plant Diversity

Cultivate a wide range of flowering plants that bloom at different times of the year to ensure that there's always a food source available for the bees and butterflies. Incorporating plants that are native to the region could also help, as they are particularly attractive to native pollinators.

Provide Water Sources

Adding a birdbath or a shallow dish filled with rocks and water can act as a watering hole for pollinators. This strategy serves two purposes:it attracts bees and butterflies to your garden, and it keeps them hydrated.

Reduce Pesticide Use

Pesticides can harm beneficial insects, like bees and butterflies. Instead of chemical pesticides, try using organic or integrated pest management strategies to control unwanted pests.

Create Habitats

Provide suitable shelters for pollinators by leaving some areas of your garden undisturbed, adding bee houses, or piling up some logs and sticks in a corner. This not only attracts them but also encourages them to stay, mate, and lay eggs.

How Can You Determine if Greater Masterwort has Been Pollinated?

Pollen Dispersal

Observe if the greater masterwort's waxy, umbrella-like inflorescence disperses the pollen. Successful pollination often involves a visible change in the pollen's color or quantity.

Flower Fading

Once pollination is successful, greater masterwort's flowers may begin to fade or wilt, indicating that they are being transformed into fruit or seeds.

Seed Formation

Another clear indication of successful pollination is the presence of seeds. Observe whether this process begins in the greater masterwort following the flowering stage.

What Tools are Necessary for Hand-Pollinating Greater Masterwort?

Small Paintbrush

A small paintbrush is required to serve as an artificial pollinator to transfer the pollen from the male to the female part of greater masterwort

Gloves

Wearing gloves can protect your hands from possible allergens or irritants while handling greater masterwort

Marker and Labels

To keep track of which flowers have been pollinated, markers and labels may be useful

What is the Optimal Time for Hand-Pollinating Greater Masterwort?

The best time window for hand-pollination of greater masterwort is in the morning when the flowers are freshly opened. This plant typically flowers between June and August, making this the best period in its lifecycle for hand-pollination.

Steps to Hand-Pollinate Greater Masterwort

Step1: Preparation

Before starting the process, ensure that you have all your tools at hand and you're wearing gloves. This is also the time to identify which flowers you intend to pollinate.

Step2: Transferring Pollen

Use the paintbrush to gently collect the pollen from the stamens (the male sexual organ) of the greater masterwort. Then, carefully transfer the pollen to the stigma (the female sexual organ) of the same or another flower.

Step3: Labeling

Once the flower has been pollinated, mark it with a label. This helps to identify the pollinated flowers and to avoid duplicate efforts.

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

Inadequate Pollinator Attraction

If pollination is failing, ensure greater masterwort's growing conditions are optimal to attract pollinators. Enhance the location's attractiveness by planting various flower types or providing water sources.

Low Pollen Production

If the greater masterwort is not producing enough pollen, consider its nutrition and sunlight exposure. Macronutrients like phosphorus can enhance pollen production.

Barren Flowers

If flowers are not forming seeds, they might be barren. You may need to support greater masterwort by hand-pollinating using a paintbrush to transfer pollen between flowers.
