Our Grapefruit Smells Funny

Question

When we cut the fruit it gives off a sulphur smell…The fruit is juicy and pink in color but has a strange odor….not very pleasant…We did just buy this home and tree was full of fruit in yard and is very old tree say 20 years…it is in Palm Desert CA
We water regularly and it is very healthy tree any ideas?

Answer 1

Depending on how regularly, watering could be the cause. Once established, they will only need water during times of severe drought. The leaves will curl inward long before any drought damage is done, as this action will conserve water.

Unless it is showing these symptoms, then it will not be necessary to provide extra water.

Saturated soils, and citrus need for sulfur will make for the perfect environment to invite sulfur reducing bacteria. These will acidify the soil, and cause the smell that you are experiencing.

There won't be much need for action. If you would like, you can add just a little DOLOMITIC LIME sprinkled to the area to raise the pH slightly. Otherwise, just let the area dry out thoroughly between waterings, at least down to 4 or 5 inches before it gets any water at all, when possible.
