Laurel leaves in a lasagna bed

[mumof2andstillsurviving]

I set up two raised beds earlier in the year using the lasagna method. This included leaves from bush we had in our garden.

I've planted it up and my vegetables are growing nicely. I gave since discovered that this green bush is a laurel bush and that the leaves are poisonous. Will my veggies be ok to eat? They are all vegetables that require cooking. I can't believe that my lovely vegetables are potentially now poisonous. Please tell me it's ok...

I found this on another forum:

Key Points:
Cyanide gas evaporates and disperses quickly in open spaces, making it less harmful outdoors.
Cyanide gas is less dense than air; so it will rise.

Cyanide is found in various forms in many plant species, including almonds (both the nuts and the plant). Most pips contain compounds that will break down into cyanide. Cyanide is found in most smokes, including cigarette smoke.

Ultimately, cyanide is an organic compound which will definitely either break down through composting or evaporate into the atmosphere. Yes, when concentrated it can be dangerous so be sensible - If you must chip or shred it make sure you do it on a windy day and don't transport shreddings in a sealed vehicle."
