hibiscus trees?

Question

My hibiscus trees are getting buds and blooms on them but have recently have mildow and white spots on the leaves. What can I do to get rid of this problem?

Answer 1

It may be powdery mildew. You can spray it with Listerine and water mixture 1/4 cup to pint of water. Or a 1/2 and 1/2 mixture of isopropyl alcohol. Spray on leaves until it runs off. If the plant(s) are outside, do not use in hot weather.

Answer 2

If its planted outside, cut half of the tree and wait for new leaves to show. If its inside plant in a pot, change dirt because too many roots. Is your location in a very hot place like Hawaii or Okinawa
