honey mesquite, poisonous?
My husband and I were in the garden last weekend tearing out our lawn and amending the soil with manure and sand. We have very few remaining plants/trees in the yard, so we were startled to discover a nasty rash/blistering on his forearms the morning after we worked in the garden. We know he isn't allergic to our gardenias, roses, or our pink melaleuca, but wondered is the spines on our honey mesquite might be the culprit. It's possible he might have scratched himself without noticing.. He says the blistering reminds him of what poison oak rash looks like. Anyone have any ideas as to what might have caused it?
