- Collect flower clusters in the early morning when plants are 40-50% flowering.
- Place the clusters into containers.
- Allow the clusters to dry at a processing location.
- Brush flowers over food strainers to separate pollen from anthers.
- Clean samples of pollen by sifting through multiple sieves of different pore sizes (pore sizes 0.119 and 0.0043 cm).
- Store collected pollen at -20°C until ready for
- Above mentioned methods allow for the relatively easy collection of a large amount of pollen.
- Allow for the collection of pollen of single and known plant origin.
- Methods such as the paint brush collection method is very time consuming and requires a large number of flowers (up to 30,000 in the case of aloes, see Human and Nicolson, 2006) to enable one to collect enough pollen.
- Sieving samples of pollen to clean all debris from collected pollen is time consuming.
- Working with large amounts of fresh pollen can be detrimental to health and increase allergies.
