A gift of Mason Bees, is a gift that keeps on giving.


What are Mason Bees?

Mason bees (Osmia lignaria)  are a friendly and efficient pollinator.  Apple, cherry and almond trees – as well as blueberries – will benefit greatly from foraging Mason Bees.

  • Mason Bees are an essential part of growing your own local organic produce.
  • Beediverse homes are a great way to encourage pollinators into your garden.
  • More bees result in better pollination, larger fruit and a greater fruit yield.

                             What to do and How to start

1.  SPRING :  PLACE THEMIn spring start with a Mason Bee home and Mason Bee cocoons

  • Place your Mason Bee home and Mason Bee cocoons on an east facing wall close to you garden or fruit trees.

2.  SUMMER: PROTECT THEM Summer time is for protecting bees from the weather and from predators with a net bag.

  • Shelter your Mason Bees from direct rain and scorching sun. Protect them from predators using a net bag or predator guard.

3.  FALL: CLEAN THEM.  Fall is time to get a scoop and storage boxes for harvested cocoons. It is also time to clean nests and assess if you need more nesting tunnels and additional mason bee homes for next spring.

  • Harvest from nesting tunnels.  Remove mud an mites with a wash in cold water.  Use an abrasive tool like a metal sieve to further remove mites

4.  WINTER:  STORE THEM.  Winter is a good time to catching up on your reading. The illustrated book “Pollination with Mason bees” will give you science based background information and great details on how to succeed your new hobby.

  • Place your clean, dry Mason Bee cocoons in a temperature and humidity controlled area such as a cool shed or fridge.  Optimum storage temperature is between 2-4 degrees C (32-36F).
