Question
I have a key lime in a solarium and it is infested with ants and has an extreme amount of black and green mold on the leaves. I've tried just about everything. Do you have any helpful ideas?

Answer
Hi Anne , I would use Pure Neem Oil from Dyan Grow, it does not wash off and does not kill your beneficials that eat the bad bugs.  Once applied you only need to spray the new growth as the old is still protected.  Over time it builds up and protects your yard.  It is also a fungicide and a miticide.  Spray the soil around the plant as the ants will not want to climb up the pot.  Also as a quick fix, wash the leaves with soapy water and it will come off.    kathy
