| My gardenia has already fought spider mites months ago. Now, some leaves are bitten off, and the general "there's spotty stuff on the leaves" look is back. (Proceeds to spray plant with heavy pesticides).
The very same day, a minirose (keep in mind they are both outdoors and in pots) had about....75% of it's leaves munched on. Grey spots are everywhere any will turn into holes. I want every insect within five feet of these plants turned to dust. How do I do it? |

| A Star Trek Phaser Gun perhaps? No, hu? Ooooookay. Some suggestions: * in mid-to-ate March, release parasitic wasps, lady beetles or lacewings. These are natural predators of aphids. Go easy on pesticides as these also kill the aphids predators, leaving your garden defenseless. * try knocking the aphids off with a very strong spray of water to get them in control (and this will also wash off the honeydew, if present). Most of the aphids will not be able to return to the plant as their bodies are easily damaged by the water spray. It is best to do this early in the day to allow plants to dry more rapidly and avoid conditions for fungal diseases. * fungal problems can be minimized using cultural controls: in the mornings, water the soil instead of the plant leaves; add 3" of mulch through the drip line; replace all the mulch if there is a heavy problem with fungal infections; water when absolutely necessary; pick up plant debris from under the shrub; separate shrubs to increase air flow between plants; use drip irrigation if possible. |

| It was up to 99% leaf hit. Then within *hours*, new buds are forming. Sheez. The impossible happens around me. Some of the typical leaf damage: And here's my Gardenia.
Whatever it was stopped munching on the Gardenia, and it too is pushing new leaves on the left, and near the stems. They love me :o) Oh. Those two plants ^^ are my beloved Daphnes. Heh. I wonder why the bugs didn't bite the Daphne... |

| you can apply a systemic insecticide that is absorbed through the roots. the insects will still do some damage but they will die when they eat the infected plant parts. |
