| I over winter my 6 citrus trees in a greenhouse. The past 2 weeks I noticed the orange tree leaves look grayish in color and looks spoty. What do you think it could be? Lloyd Rasmussen |
| It is really difficult to diagnose a plant problem without seeing so I will offer an educated guess - check the undersides of the leaves for presence of sucking pests such as aphids, mealybugs, scale or whiteflies. These pests can cause a stippled or spotty appearance to the leaves and a general dull cast. Hope you discover what's causing the problem! |
