Trial using Foamstream October 2017

On the 19th October 2017 we carried out a trial on the paths and irrigation sand beds on the nursery. 

What we are hoping to achieve is the removal of weeds and overwintering seeds / spores so that the nursery will be dramatically more weed and algae free next year. I believe this may be the first time it has been used in Northern Ireland (but someone may know differently) so the experience should be interesting.

Trial using Sodium bicarbonate (baking soda) August 2017

During August we trialled liverwart removal. Sodium bicarbonate worked well on killing liverwart. As of October, it remains killed. 

It did not effect Nostoc sp. is a cyanobacterium (also called a blue-green algae).

 

Update August 2018 & August 2019

- At Beech Grove Nursery we have trialled sodium carbonate on the Nostoc algae with great success. We also trialled sodium carbonate with hydrogen peroxide (used in clothes dry cleaning) but this did not eradicate the algae compared to the success with sodium carbonate.
