I want to plant some fruit bushes and herbs in my garden, but we have a problem with cats and some dogs, that have messed in the soil in the past. We clean up what we can but on occassions there must be some that we have missed.
I'm unsure if I should use the soil or change it.
as long as it's not swimming in the stuff it should be O.K. remember, a lot of animals have been crapping on this planet for a long time, it's covered in the stuff!! (humans just put theirs into the water) ;)
You can use the soil it will be fine for the plants. Just make sure you wash your hands well afterwards and scrub nails. Then you wont catch anything.
