Almond Pollination Requirements for Growers and Beekeepers

California almond industry guidelines recommend a minimum of 8 frames of bees per hive for pollination contracts. That's the standard you'll see referenced in premium contracts. Understanding where that number comes from, and what other requirements define a properly executed almond pollination engagement, helps both growers and beekeepers write contracts that protect their interests.

This is a reference guide for both sides of the almond pollination relationship.

TL;DR

• California almond pollination consumes roughly 80% of the US commercial hive population every February, making it the most supply-constrained pollination market in the country.
• Per-hive rates have held between $185 and $220 for 6-8 frame colonies over recent seasons.
• Contracts are typically signed October through November for the following February season; operators without agreements by December are working from a weak position.
• Hive strength minimums range from 6 to 8 frames of bees depending on the grower, with premium-strength colonies commanding $200-215/hive.
• varroa management, documentation, and logistics coordination in the 6-8 weeks before delivery determine whether almond season is profitable or a breakeven event.

Hive Density: How Many Hives Per Acre?

The standard commercial range for almond pollination is 2-3 hives per acre. The specific number in your contract depends on:

Orchard variety mix: Almond is self-incompatible and requires cross-pollination from a compatible variety. Orchards with good pollenizer variety integration typically need 2-2.5 hives per acre. Orchards with poor pollenizer coverage may need 2.5-3 or more.

Orchard age and density: Younger orchards have fewer flowers per acre than mature orchards. Mature orchards in full production with 100+ trees per acre have dense floral coverage that makes each hive more effective.

Historical set: Growers with a history of poor fruit set despite adequate hive counts may have factors beyond hive density contributing to the problem (soil, irrigation, weather). Increasing density alone doesn't always fix a systemic issue, but many growers reasonably try it.

Market expectations: In high-yield production systems targeting maximum nut weight, some growers use 3 hives per acre as a default regardless of orchard characteristics.

Hive Strength Requirements: What Growers Specify

California Almond Board guidance references 8 frames of bees as a "strong" colony standard. Commercial contracts typically operate with:

Minimum standard (most commercial contracts): 6 frames of bees covering both sides of 6 frames in a 10-frame Langstroth box.

Mid-tier standard: 7 frames of bees, sometimes paired with a requirement for at least 3-4 frames of healthy brood.

Premium standard: 8 frames of bees, used in high-value contracts where growers are paying premium rates for premium performance.

Hive strength should be assessed before loading and documented with an inspection report. The California Almond Board's recommended assessment window is within 48 hours before delivery, though many contracts allow a 7-day pre-move assessment.

PollenOps pre-move strength assessments generate a compliance report from the field checklist that can be attached to the contract record and shared with the grower as documentation.

Timing Requirements: When Do Bees Need to Arrive?

The standard placement requirement is delivery before 10% bloom. Some contracts specify a date range: "no earlier than January 30 and no later than 10% bloom" is a common structure that gives both parties flexibility while defining the critical deadline.

Practical timing by region (normal years):

• Southern San Joaquin Valley: target delivery February 5-12
• Central San Joaquin Valley: target delivery February 10-18
• Sacramento Valley: target delivery February 15-25

Warm years advance all of these dates by 1-2 weeks. Cool years push them later. PollenOps almond bloom alerts track regional conditions and fire 5-7 days before projected 10% bloom, giving beekeepers the lead time they need to confirm truck schedules.

Documentation Requirements: What the Contract Should Require

A well-structured almond pollination contract specifies:

Delivery record: GPS-confirmed yard location, delivery timestamp, and hive count at arrival. This is the foundational document that proves when bees arrived and how many.

Strength assessment: Pre-move strength scores for the delivered hives, with a signature from the inspector. If the contract specifies 7 frames of bees minimum, the assessment report shows whether each delivered hive met that minimum.

Placement confirmation: For contracts with specific placement requirements (cluster spacing, placement zones), documentation of where clusters were placed within the orchard.

Service period compliance: Proof that hives remained at the contracted location for the full service period specified in the contract.

Pickup record: GPS-confirmed removal timestamp and final hive count when bees are retrieved at the end of the service period.

What Documentation Do I Need to Satisfy Almond Pollination Contract Requirements?

If you're a beekeeper working almond contracts, your documentation package should include:

1. A copy of the signed contract with all terms, including hive count, strength minimum, delivery dates, and payment schedule
2. Pre-move strength assessment report for the delivered yard
3. GPS delivery record with timestamp from your field check-in
4. Grower arrival notification sent within a few hours of placement
5. GPS pickup record with final hive count at the end of the service period
6. Invoices referencing the delivery record data (hive count, delivery date)

PollenOps contract compliance documentation generates and stores most of this automatically from your operational workflows. The compliance record for each contract is a byproduct of documenting your work, not a separate administrative task.

What Hive Strength Do Almond Growers Require in Their Contracts?

This varies by grower and market segment:

Large commercial growers with professional procurement tend to specify 6-7 frames minimum and may require formal strength inspection reports before payment is released.

Mid-size family operations often specify 6 frames minimum but rely more on the beekeeper relationship and less on formal documentation.

Premium organic or branded operations may specify 8 frames minimum and require third-party assessment.

If you're a grower writing a contract, specifying a minimum that matches the California Almond Board's published guidance is a defensible standard. If you're a beekeeper, understanding what each grower's standard is before signing is essential. Don't sign contracts to minimum standards you regularly can't meet.

How Many Hives Per Acre Is Standard for Almond Orchards?

The industry standard is 2-3 hives per acre, with most commercial contracts falling in the 2-2.5 range. The California Almond Board's own research supports 2 hives per acre as adequate for typical commercial orchards, with higher density providing diminishing returns beyond 3 hives per acre in most scenarios.

Some growers, particularly those with older orchards or documented pollination challenges, request 3+ hives per acre. For a 300-acre orchard at 3 hives per acre, that's 900 hives, which is a significant commitment from the beekeeper and a meaningful cost for the grower. The density premium should be justified by specific orchard characteristics.

Frequently Asked Questions

What hive strength do almond growers require in their contracts?

Most commercial almond contracts specify 6 frames of bees as a minimum, with some premium contracts requiring 7-8 frames. The California Almond Board's published guidance references 8 frames as a "strong" colony standard. Growers working with experienced beekeepers over multiple seasons often adjust their standards based on the performance they've observed from that operator. New beekeeping relationships typically require formal documentation of strength compliance.

How many hives per acre is standard for almond orchards?

The commercial standard is 2-3 hives per acre. Two hives per acre is the California Almond Board's research-backed baseline for typical commercial production conditions. Growers with specific orchard challenges (poor variety integration, historical low set) often request 2.5-3 hives per acre. Beyond 3 hives per acre, the evidence for incremental benefit is weaker, though some high-value orchards use higher density.

What documentation do I need to satisfy almond pollination contract requirements?

At minimum: a signed contract with all terms specified, a pre-move strength assessment report for the delivered hives, a GPS delivery record with timestamp, a grower arrival notification, and a GPS pickup record at the end of the service period. Premium contracts may also require placement mapping showing cluster distribution within the orchard and formal third-party strength inspection. PollenOps generates most of this documentation automatically from your operational workflows.

How early should almond pollination contracts be negotiated?

Large almond growers and broker networks begin securing hive commitments in July and August for the following February season. Written contracts are typically signed October through November. Operators who do not have signed agreements by December are working from a weak position since most quality hive inventory is already committed. Start grower outreach in mid-summer and target signed agreements before Thanksgiving.

What documentation is required for hive delivery to California almonds?

California requires a Certificate of Health for out-of-state colonies, issued by the origin state's apiary inspection program within 30 days of entry. The certificate must certify freedom from American foulbrood, European foulbrood, and Varroa destructor below treatment threshold. Some states require small hive beetle freedom for California entry. In addition, many growers now expect documentation of pre-delivery mite counts confirming colonies are below threshold.

What happens to hives after almond season ends in late March?

Post-almond options include moving north for Pacific Northwest cherry or apple pollination in April-May, routing to Michigan or Maine blueberries in May-July, transitioning to summer honey yards in North Dakota or Montana, or staying in California for splits and rebuilding. The right choice depends on hive strength coming out of almonds and downstream contract commitments. Operators who plan their full-year circuit in advance can optimize both pollination revenue and honey production.
