lime tree
 

Hi - about this time of year the lime tree in my garden starts dropping sticky deposits - no problem. But this year I notice it also sheds some form of black substance that coats all plants, grass and my new patio with a black stain. Any idea of whether this is normal, what it is, if I can prevent it, and how I can wash it off my patio!? Thanks

The sticky stuff is aphid droppings and the black stuff is sooty mold
growing on the sticky stuff.
