A lemon tree that is extremely bitter

Question

For 2 years now, my lemon tree has produced lemons that are extremely bitter. How do I counteract this? What would cause this?

Answer 1

This is usually the case when the lemon is not fully ripe. Even if it is yellow, it can still be far off from ripening. The same goes for green lemons. Sometimes they are ripe and never turn yellow. It can take up to nine months for these fruit to ripen properly from the time they start to form.

You should also be feeding this a citrus fertilizer at least once per year.
