Yellow leaves on Orange Tree

coday00April 6, 2011

I am having a heck of a time with an orange tree. The leaves are turning yellow and falling off. I think I have narrowed it down to either an iron deficiency or the roots are way too wet. I have pictures posted at:

Any help would be greatly appreciated.

In December we received 15+ inches of rain (hence the mudslides that made the national news). Since then I have watered it once a week fairly heavily.

The leaves on my navel orange look EXACTLY the same. The funny thing is I get alot of flowers and good fruit.

I have my tree planted in my back yard in my lawn. I have a circle of just dirt around the base of the tree but I think the grass is stealing the nutrients from the tree. Im planning on cutting more grass away from the tree and feeding it with a 20-20-20 fertilizer I have with tons of micro nutrients. Plus I think I have been a little to liberal with the water. The grass dries out so quick and while Im water I water the orange tree as well. Im sure it is from lack of nutrients and possible over watering.

Probably a combination of a lot of water, cold temps and some chlorosis. Check down to see really and truly how wet the roots are. If they're soaked, stop watering for a bit. Then, give it a very good fertilizing with micronutrients and hopefully your new flush will green up. The older yellow leaves may drop, but you'll see new leaves push out from the bud unions.
