Propolis harvesting is a delicate process that requires careful timing, the right tools, and proper post-harvest handling to ensure purity and quality. The most common method involves using a propolis trap or mat, which encourages bees to deposit propolis in a controlled manner. Harvesting typically occurs in early fall when propolis production peaks, and yields can range from 50g to over 1kg per hive depending on techniques used. After collection, propolis must be cleaned through methods like freezing, water soaking, or gentle heating to remove impurities before further processing.
Key Points Explained:
-
Timing and Hive Conditions
- Harvesting is most effective in early autumn when bees naturally produce more propolis to prepare for winter.
- Ensure the hive is healthy and untreated with chemicals to avoid contamination.
-
Propolis Trap/Mat Installation
- A reusable plastic propolis trap or mat is placed under the hive lid. Its grooved design mimics gaps bees instinctively fill with propolis.
- Bees deposit propolis to block light and drafts, typically filling the trap within weeks.
-
Collection Process
- Once the trap is full, remove it and freeze it briefly to harden the propolis, making it easier to scrape off.
- For mats, flexing the plastic loosens the propolis chunks.
-
Yield Optimization
- Standard yields range from 50–150g per hive, but specialized mats and ideal conditions can increase this to 1kg+.
- Some beekeepers use multiple traps or rotate mats to maximize production.
-
Cleaning and Processing
- Water soaking: Submerge harvested propolis; impurities float while propolis sinks.
- Heat separation: Baking at 200°F (93°C) for 2 hours melts wax and separates debris.
- Avoid high heat to preserve bioactive compounds.
-
Quality Control
- Never harvest from hives treated with pesticides or miticides.
- Store cleaned propolis in airtight containers away from light and moisture.
Propolis harvesting blends beekeeping intuition with simple tools, yielding a product that supports both hive health and human wellness. Have you considered how seasonal rhythms influence other natural product harvests? This process mirrors the careful balance of working with nature’s timelines.
