It’s a common frustration for gardeners—you see your fruit tree covered in blossoms in early spring, promising a bountiful harvest, but as the season progresses, no fruit sets. What happened? If you have the correct cross-pollinators for your trees, then the culprit is often unfavorable weather conditions, particularly excessive wind or rain, which can significantly impact pollination and fruit development. Understanding how these factors affect fruit set can help you take proactive steps to protect your trees and maximize your harvest.

What is Fruit Set?

Fruit set is the process where pollinated flowers develop into young fruit. It depends on several factors:

Successful pollination – Pollen must transfer from the male part of a flower to the female part.
Favorable weather – Ideal temperatures and moisture levels help pollination and fertilization.
Tree health & nutrition – Strong, well-fed trees are more likely to retain fruit.

If any of these factors are disrupted—especially by poor weather conditions—the fruit set may be incomplete, delayed, or even fail entirely.

How Windy Springs Affect Fruit Set 🌬️

While some wind is beneficial for pollination (especially for wind-pollinated trees like pecans), strong winds can be detrimental:

Blowing pollen away – Wind can scatter pollen too far from its target, reducing fertilization chances.
Damaging blossoms – Fragile flowers can tear or dry out in excessive winds.
Disrupting pollinators – Many fruit trees rely on bees and other insects for pollination, but high winds make it difficult for them to fly and do their job.

Tips to Protect Against Wind:
✔️ Windbreaks – Plant hedges or install fencing to shield fruit trees.
✔️ Staking young trees – Prevent breakage in young trees with proper support.
✔️ Provide alternative pollination – If natural pollination is low, consider hand-pollinating flowers using a small brush.

How Rainy Springs Affect Fruit Set

Rain is essential for tree health, but too much rain at the wrong time can harm fruit set:

Washes away pollen – Rain can dilute and remove pollen from flowers before pollination occurs.
Reduces pollinator activity – Bees and other pollinators tend to stay sheltered during rainy, cold weather.
Increases disease risk – Wet conditions promote fungal diseases like blossom blight, which damages flowers before fruit can form.

Tips to Protect Against Excess Rain:
✔️ Plant flowering trees in well-drained areas to prevent root stress.
✔️ Encourage pollinators on dry days – Provide shelter for bees and plant pollinator-friendly flowers to attract them.
✔️ Use fungicide sprays if persistent rain leads to disease concerns (especially for stone fruits like cherries and peaches).

What If Your Trees Experience Poor Fruit Set?

If your trees fail to set fruit, don’t panic! Here’s what you can do:

Thin excess blossoms early next season – Overloaded trees can struggle to set fruit properly.
Increase pollination opportunities – Introduce native bees or hand-pollinate if necessary.
Improve tree nutrition – Ensure trees receive balanced fertilizers with phosphorus and potassium to support fruiting.

This is an excellent article. I’m checking it because here in San Francisco, we have both a Anjou Pear and a Bartlett Pear in our back yard. As of end March, the Anjou is in full bloom, but we just had several days of light rain. During the past couple weeks, the tree appears being visited by at least 3 to 5 honey bees each time I check it on sunny, warmer days. Last year, it was full fruit and produced a very extensive yield, 500 plus pears. I’ll be curious to see what evolves this season. The Bartlett pear blooms 4 to 6 weeks later, but the pears ripen earlier.
