Q.How Can I Save Huge Outdoor Ivy. Firstly Had Back Sooty Deposit On Some Leaves. Now Dying And White Mold Spots Everywhere.
Ivy 20ft x 10ft x2ft. Root in restricted area next to patio. Given One spray a week ago of neem oil, water, emulsifier. Have ordered potassium bicarbonate to add to next spray due today. Desperate to save as barrier between neighbours.

I would cut the brown area back by about 2/3 to get rid of most of the issues. They should regrow quickly. The sooty mold was probably a result of aphids or scale. Continue to apply Neem oil till the insects are gone. Make sure the white spots aren't mealybugs. The narrow area where it is planted probably needs a boost of compost or manure. Make sure they are getting adequate water.
