Why are my Lemon Tree Leaves Yellow?

by on August 20, 2012

lemon_treeOne of the joys of living in a warm zone line California and Florida is the ability to grow delicious citrus fruit. From oranges and grapefruits to lemons and limes, fresh citrus packs a tasty, vitamin-rich punch. What happens when there is trouble in paradise and one of your beloved citrus trees shows signs of distress?  Why, you just visit UrbanFig to find out the answer, of course!

HELP! My lemon tree leaves are turning yellow!

There are two primary reasons for lemon tree leaves turning yellow, both of which are pretty easy to deal with.

  1. Too much water.
    Chill out with the watering! You’re overdoing it and the citrus trees don’t like it very much. A good rule of thumb for the most part is to water your citrus trees deeply just once a week. They don’t need more than that. If you aren’t watering excessively, then have a look at the soil. Is it possible that you have poor drainage? Citrus trees don’t like wet feet, so they need to have adequate drainage to flourish and stay green.
  2. Nitrogen Red Alert!
    Another possibility is that your lemon tree is crying out for more Nitrogen. Side dress with a Nitrogen-rich fertilizer and your yellow leaves should be a thing of the past.

It is important to note that once your leaves begin to turn yellow, they won’t turn green again. You will have to watch for new leaves to see an improvement in your lemon trees.

Hi Robert –
An easy way to fertilize your citrus tree is to add something like this: http://shop.urbanfig.com/e-b-stone-organics-citrus-fruit-tree-food-4lb/

Compost is also rich in nitrogen. Try adding some citrus fertilizer and some compost and see how it goes. Remember, new leaves have to grow out before your lemon tree will start looking healthier, the yellow leaves will not turn green. So give it a few weeks and see what the new leaves look like. Happy Gardening!
