Q.Unidentified Citrus Plant BENT Not Curled Leaves

Zone 96790 | iambethdavis added on December 11, 2020 | Answered

I dropped some seeds in soil last February and this citrus, which is either lemon or grapefruit, has severe leaf deformation. The roots look healthy and are just starting to swirl around base of pot so I will transplant. But this leaf issue has been present for a while. No visible pests and the soil looks healthy. I am on your weekly newsletter email list nd love it!

This happens, usually, due to a pH swing. Unfortunately, soil health cannot be determined by looks. Many problems that occur in soil are, either, microscopic or chemical.

There are ways that allow you to test for these problems, though. Testing pH and nutrient content will rule out either of those issues. Once those are corrected, the affected leaves will not return to health. New growth will cease to curl and bend, however.

Should you find that your pH is fine, and your nutrient content is not overbearing, then you can begin to diagnose more rare issues, such as viral, bacterial, or fungal pathogens.

From experience, this reminds me of my own grapefruit. The bottom lobes of the leaves are common in many citrus, but they can be quite noticeable in grapefruit.

They seem to be quite sensitive to soil changes, so keep everything as stable as you can. I can't confirm that yours is a grapefruit, but it does seem to fit the bill.

Here is an article to help you with grapefruit care:


These will help you when the tree is mature:
