Summertime--and you are outside enjoying your garden. But wait, what is that weird thing you see on your plant?
It's not always easy to diagnose garden problems. Sometimes insect damage looks like a fungus problem and vice versa.
Giant Whitefly (insect) damage and Citrus Leaf Miner (insect) damage can look like a fungus issue, while scab and shothole fungus can look like insect damage.
In the case of aphids and other sucking insects, sooty mold (a fungus) forms on the insect secretions.
Treatments should be tailored to the problem.
We hate to hear of insecticides being applied to a fungal problem--and vice versa.
If you are stumped for a solution, cut a fresh sample and bring it in to our Info Center.
We need to see how it looks on the plant, so please bring a small branch showing the damage. Transport it in a plastic bag and let one of our Nursery Pros take a look.
Photos, especially on a camera or phone, are more difficult, because we cannot examine them as closely. You can email us images to firstname.lastname@example.org and we can always try to ID a problem that way, but seeing it is best.
Sometimes the problem is in the plant's environment and no treatment is necessary. Just changing the plant's growing conditions will ease or fix the problem.
Timing of treatment is critical to its success. Help us help you. We recommend earth-friendly solutions whenever possible.
