The most common reason your lemons are browning inside is that they are overripe and beginning to rot while still on the tree.
Here's a breakdown of the potential causes and what you should do:
-
Over-Ripening: Lemons, like all fruits, have a lifespan. If left on the tree for too long, they will naturally start to decompose. This internal browning is a sign of that process.
-
Excessive Moisture: High rainfall and humidity during the lemons' ripening period can also contribute to internal browning. The excess moisture can encourage fungal growth and rot.
-
Fruit Quality: Sometimes, even seemingly healthy lemons can have internal browning due to underlying issues.
What to Do:
-
Discard Brown Lemons: Lemons that are brown inside are likely to have an unpleasant, off-flavor and should not be consumed.
-
Harvest Regularly: Pick lemons when they are ripe and before they become overripe. Check your trees regularly, especially during periods of high rainfall.
-
Proper Storage: If you've harvested lemons and they're not yet brown, store them properly in the refrigerator to extend their shelf life.
-
Monitor Tree Health: Ensure your lemon tree is healthy and receiving proper care, including adequate sunlight and drainage. Healthy trees are less susceptible to producing fruit with internal issues.
