Q.Herbicide in manure – help!
I have an allotment and purchased a half ton of manure from our groundskeeper that turned out to contain herbicide of some sort. He didn’t know at the time and replaced the bag for a bag of compost, but I had already spread some over my spuds, spaghetti squash and beans.
The potato leaves are curling but my squash seem fine.
I’m wondering what can I do to remedy the situation and undo any nasty effects it may have had on my crops? Any advice would be greatly appreciated.

By regulations most herbicide must dissipate over a period of time, but the damage could be done already by the appearance of your plants.
You can try washing the soil with heavy watering.
A soil test can also be helpful; to know how to help your plants and the only way to really know what amendments your soil needs.
