Know when your Mason bees are ready.
Your garden + local weather + growing degree days + decades of practical bee knowledge.
From a small company with a big heart, welcome to your Pollinator Oasis. We'll help you decide when to put Mason bee cocoons out for emergence, when heat or cold may require protection, how many bees your garden may need for pollination, and what supplies to prepare. We're here for your what to do planning.
Weather-aware guidance
Use local conditions to make better timing decisions.
GDD-based emergence
Growing degree days help turn seasonal biology into practical next steps.
Bee knowledge stays free
The information you need to care for pollinators is never gated.
From “Is it time?” to “I know what to do.”
Simple guidance, grounded in biology and local conditions.
We follow your season
Pollinator Oasis uses local weather, growing degree days, and your garden information to help estimate when mason bees are nearing the right emergence window.
Get weather-event guidance
When unusual heat, cold, or changing conditions could affect cocoons, the app can help you know when a protective step may be needed.
Learn the next skill
Release, nesting, pollination, harvest, cocoon care, and habitat guidance are connected to the point in the season when you need them.
Your plants become your pollination plan.
Tell us what is growing. Pollinator Oasis helps connect bloom, bee needs, release timing, weather, and supplies.
Add your garden
What is growing?Build a picture of fruit trees, vegetables, ornamentals, and other bee-relevant bloom.
See bloom intensity
How much will flower?Estimate bloom volume and overlap so you can see when pollination demand is building, peaking, or tapering.
Estimate bee needs
How many mason bees?Translate your garden's bloom profile into an estimated mason bee pollination requirement.
Plan emergence timing
When should cocoons go out?Combine GDD, local weather, and garden readiness to help select an appropriate cocoon release window.
Watch the weather
Heat or cold ahead?Identify conditions that may call for protection, delayed release, shade, relocation, or closer observation.
Know what you need
Cocoons + nesting + suppliesTrack what you already have and identify likely gaps before the critical seasonal window arrives.
Your pollinator year
The website can change with the season, just like the bees do.
Spring
Release & pollination
Emergence timing, bloom readiness, weather protection,
flowers, nesting, mud, and active pollination.
Summer
Leafcutters & habitat
Warm-season pollinators, nesting support, garden
resources, and community science.
Fall
Harvest
Open suitable nesting materials, collect cocoons,
record results, and prepare for next year.
Winter
Care & prepare
Store cocoons correctly, review inventory, and prepare
for the next season.
Understand the why, not just the alert.
Pollinator Oasis is designed to help people learn, not to put essential bee-care information behind a purchase.
The app, website, and Crown Bees educational videos can explain why bloom matters, what GDD tells us, what weather can change, how mason bees nest, how harvesting works, and what successful cocoon care looks like.
Built on decades of mason bee leadership.
Dave literally wrote the book.
Crown Bees founder Dave Hunter co-authored Mason Bee Revolution, helping bring practical mason bee keeping to gardeners in a way that is understandable, repeatable, and grounded in real-world experience.
Pollinator Oasis carries that knowledge forward in a new form: practical bee expertise paired with your garden, your local weather, growing degree days, and simple seasonal guidance.

More than an app. A reason to go outside together.
Pollinators create natural opportunities for family, neighbors, and community to connect.
For families
Share a seasonal project that grandparents, parents, children, and grandchildren can all observe together.
For community scientists
Notice what is happening in your garden, learn why it matters, and help build stronger local pollinator awareness.
For the planet
Create habitat, support pollinators responsibly, and turn small garden actions into meaningful stewardship.
Services that continue the cycle
Support is available when people want a helping hand.
Harvest Service
Help with opening suitable nesting materials, processing cocoons, recording results, and preparing for the next season.
Bee Buyback
A pathway for qualifying surplus bees to support a broader pollinator network while encouraging responsible harvest.
Bee Buddies
Philanthropic and community opportunities that help more people participate in pollinator stewardship.
App & legal information
Clear, easy-to-find information for customers, Apple, and Google Play review.
Release timing, bee-quantity recommendations, bloom calculations, and weather guidance are decision-support estimates based on available biological, environmental, and user-entered information. They are not guarantees of emergence, nesting, pollination, or crop yield.
You can be successful at this.
Pollinator Oasis makes the science supportive rather than intimidating. The calculations happen in the background. You see what matters now, why it matters, and what to do next.
Start with mason bees. Grow the oasis.
Mason bees are the beginning. The same garden-centered model can expand into leafcutter bees, hummingbirds, habitat, and other pollinators over time.
