I've been getting advice that one should not compost walnut
leaves as they contain cyanide. Is this true?
We've got rhubarb growing under one! What about eating that?

Any advice would be appreciated as the books seem silent on this.

i have herd rumors that when the nut dies (walnut) it produces cyanide so if they are decomposing in your yard i would watch what you grow.

The technical term for the posters of those theories is nuts.

Cyanide is produced by many plants, especially the Rosaceae,
and biodegrades very fast indeed. The toxin produced by the
black walnut is not produced by the common walnut in quantity,
and is entirely produced by the roots. Walnut leaves compost
as readily as most others, and food grown under walnuts is fine
to eat.

Just remember, boys, girls and chickens, that the expression The
Web Of A Million Lies is a gross underestimate.

Which sort of walnut?

The walnut produces a toxic compound called juglone that will stunt the
growth of many other plants within the root run of the tree. But it is a
substituted naphthoquinone *not* cyanide. See

Not true at multiple levels. Tree leaves in general are best composted
together to make leaf mould since too many of the contain inhibitors
against fungi and bacteria that will stall a hot compost heap.

Plenty of things in the garden contain cyanide or glycocides or worse.
Bamboo shoots and apple pips for instance. This time of year one of the
more deadly things are the beautiful autumn crocus colchicums.

We've got rhubarb growing under one! What about eating that?

Are you aware that the oxalic acid in rhubarb leaves is toxic?
If it grows then it is fine. Some plants will not grow in close
proximity to an established walnut tree.

Any advice would be appreciated as the books seem silent on this.

There are lot of stupid rumours on the internet and even more stupid
people repeating them in total ignorance.
