I have been trying to find a way for a while now of growing onions with no need to weed. It is such a pain having to be very careful between sets with the hoe, and inevitably I catch the odd one or two.
Seeing how professionals’ grow some veg through a membrane, I had an idea of trying to do the same with onions sets.
Before laying down the black plastic, I had dug in lots and lots of chicken manure. This black membrane is also breathable, and infact lets water through but stops weeds in their tracks. It also warms the soil up tremendously and keeps in moisture stopping evaporation.
I have had to construct a number of slats simply to weight the membrane down so the wind does not get in underneath and lift up. I will have to watch out for slugs doing this, but lets see if I can grow maintenance free onions this year.
Oh, and the variety, is as usual ‘Sturon’ that I normally set away in cells in the greenhouse.
