I did wear gloves most of the time...I touched lots of plants it would be difficult to make a complete list of all the plants I may have touched.

I was trimming plants & adding compost around plants. I did yearly irrigation system checks - which required some kneeling down and getting in the dirt (without my gloves). I did use some iron chelate fertilizer...I will look up info about it to see if there are any health hazards.

There was one fragrant flowering tree nearby that is considered allergenic...African Sumac..but it has not bothered me in the past.

Thank you for making me think about it, I will think about this more and go through my notes.
