Bill Mollison, in PcII, p 25, says to plant Phacelia in orchards as it is insectary for predators of Prospatella pest.

Hi, I'm a beekeeper in ireland and have recently been informed that Phacelia tanacetifolia is an excellent crop for honeybees I have been infomred that its possible to get 1 tonne of honey from 50 acres of this crop. Can anyone tell me how much seed I would need for 9 acres of ground.

   Wed Jul 5 2006

I have worked it out to around 109 kilos. Not being very mathematical, I am probably wrong, but at 4047 square metres to an acre - 9 acres - that's 36432 square metres - and a sowing rate of 3g to every square metre....that would bee (;-) ) 109kg?

Reply to Philip McCabe. I have grown this regularly as a green cover in S.E. Scotland. It does very well indeed and is extremely attractive to bees. However, the resulting honey is like water, only suitable for blending. The idea mixer is oil seed rape honey which otherwise tends to be like concrete. The recommended seed rate for Phacelia is 10kg per hectare. In practice, 5 kg per hectare is more than sufficient.
