Q.Problem with rye grass. About a month ago I used lucerne mulch all over my back garden. Now my garden beds have rye grass sprouting
everywhere. The lucerne was greener than usual. I applied around 15 to 20 bags around my garden bed including in my vegetable patch. I turned the soil after a few weeks to help it break down. Soon after I noticed green grass shouts appearing everywhere the beds. I don’t want to use zero as this will effect my shrubs, vegetables and hedges. I tried a product called slasher as this was organic. I may have not used enough to fix the problem so I will give this product another go. I am concerned that this will overtake the garden and would appreciate your advice as to how I could alleviate this rye grass. My garden nursery told me they new it was rye grass due to the pink stems. First the nursery told me that it would have blown in from other peoples garden but this is not the case as the rye grass only appears where I have applied the mulch and not appeared anywhere else.
I'm afraid it will take herbicides to kill it off.
