Many people are afraid of bees, but they are universal pollinators in the garden and in the garden. Spring is usually the time the bees leave their shelter: females looking for a nesting site. I help them — organize a multi-storey smelink. It is simple: number of beams in a quiet place, in a spiral — miniature hives of yellow in old boards (height 120 mm, width and depth — 100; a black hole with a diameter of 18 mm); inside — cotton or oakum. Enough two or three such Smolenice on the site — be it a high yield!
