ChatGPT artificial intelligence Archives

You’ve probably already heard about ChatGPT, the new artificial intelligence program by OpenAI that is being called “scarily good.” Well, okay, I thought, maybe it is scarily good about techy stuff but how good is it with gardening advice? So I asked it this fairly basic question.

What causes plant leaves to turn yellow with green veins?

Here is what ChatGPT answered:

“Leaves on plants that turn yellow with green veins is a condition known as chlorosis. Chlorosis is caused by a lack of chlorophyll, which is the pigment that gives leaves their green color. The green veins on the leaves indicate that the plant is still producing some chlorophyll, but not enough to fully color the leaves.”

Okay — so far so good, I thought. And it continued…

“There are several causes of chlorosis, including:

Nutrient deficiencies: A lack of iron, manganese, zinc, or other essential nutrients can cause chlorosis. This is often due to a lack of these nutrients in the soil, or a pH imbalance that makes it difficult for the plant to absorb them.
Disease: Some plant diseases can cause chlorosis, such as leaf spot or rust.
Pest infestations: Pests such as spider mites or aphids can suck the sap from the leaves, causing them to turn yellow.
Environmental factors: Extreme heat, cold, or drought can stress plants and cause chlorosis.”

Item 2 is where ChatGPT begins to slip off the track. Leaf spot or rust do not look remotely like chlorosis; they are orangy yellow round spots on leaves not yellow leaves with green veins. Spider mites and aphids can damage plants but the effect is also spotty leaves–smaller spots–not leaves yellowing.

Then Chat GPT goes for the solution:

“To fix this issue, you need to find the root cause of the problem and take appropriate action. A soil test can help you determine the pH and nutrient levels in your soil and make recommendations for correcting any imbalances. You can also consult with a local nursery or botanical garden for help identifying and treating any diseases or pests that may be affecting your plants.”

That’s where ChatGPT ends.

My conclusion is that it offers basically good advice–as I did in an earlier post about yellowing leaves. But it falls short of the detailed information I wrote about, including short term, fast fixes to out-of-season yellowing leaves. ChatGPT clearly hedges its bet by suggesting that one should consult with a real local human being. (Or maybe a Master Gardener!)

Is ChatGPT trustworthy?

OpenAI, the company that developed this A.I. warns not to trust what ChatGPT says completely — that it sometimes just makes things up. This is a failing of other artificial intelligence programs, too. My guess is that it doesn’t want to appear ignorant — which, of course, opens the question about whether an artificial intelligence computer program can behave as if it is embarrassed by a lack of knowledge — but that is for another blog. Not this one.

I have another gardening question for ChatGPT — one that should be more challenging, but, unfortunately, the Open AI website is so busy that I haven’t been able to get on it again. I’ll report about it, if I can talk with it again.
