Gardeners’ Q&As

Question: This year my azaleas and sycamore leaves developed a bleached-out appearance and the underside of the leaves was covered with black tar-like spots. What causes this?

Answer: Both azaleas and sycamores are susceptible to damage caused by an insect called a lace bug. Lace bugs are usually found on the underside of leaves and, although small, the adult stage is visible to the naked eye. Damage results from the insect sucking out cell sap, resulting in mottling of the leaf. The black tar spots are actually the insect's excrements (frass). Control on azaleas can be accomplished with recommended sprays such as Orthene or Isotox. Control on sycamore may be impractical if the trees are large. If no action is taken on sycamores, the trees may drop leaves early, but no permanent damage will result.

Question: My family has always dusted vegetables rather than spraying them and we have always debated the question as to how long is the insecticide dust effective. Sometimes, unless it rains, the white dust residue will remain for weeks.

Answer: Garden dusts are only effective for 5-7 days regardless of how long the actual dust particles applied remain visible. This is why it is so important to apply only a very thin—almost transparent—layer of dust when spraying. If you pour it on, as many people do, after several applications you will have a "whitewashed" plant which can actually be damaged by the excessive accumulations. All vegetables and fruits should be washed before use.

Question: My pecan tree produced a bumper crop last year but set a light crop this spring. Can you tell me the likely cause for the difference?

Answer: Pecans tend to produce heavy crops on an alternate year cycle. However, under a properly managed production system, the alternate-year bearing characteristic can be reduced. This usually amounts to applying adequate nitrogen fertilizer and proper watering throughout the production season. Zinc sprays and a pest management program are beneficial as well.

Question: Do you recommend use of fertilizer spikes around landscape trees?

Answer: While fertilizer spikes will not harm landscape trees I do not recommend their use. Fertilizer spikes provide a concentration of nutrients in a limited area while not providing any nutrients in the remaining area. The roots of most trees extend out as far as the limbs (known as the dip line) and in many cases, extend out much farther than the limbs. Tree roots that absorb water and nutrients are also distributed fairly uniformly under a tree’s drip line. I recommend use of a complete fertilizer (such as 15-5-10 or 13-13-13) that is spread uniformly around the tree within its drip line.
