Salt burn on myers lemon tree?

It's been about two weeks since I added the steer manure mulch around my citrus trees. All but the myers lemon are doing great. The myers lemon tree had a few leaves that started to curl; then while looking at the leaves I spotted some webbing and thought I'd better hose it down to kill the spider mites. After hitting the citrus tree with a soft spray of water, nearly all of the leaves fellto the ground!

I guess I must have added more steer manure than I needed to this poor lemon tree. I did have another issue with this same lemon tree about six months ago where some of the branches become black and had leaf curl. After removing the branches in question, the lemon tree acted normal.

Only time will tell if this myers lemon tree will come back full strength. I did remove a lot of the steer manure mulch and flooded the tree well to help leach away some of the salts. I was told it may have been to much nitrogen? But I have also hear that steer manure has a lot of salt?

Any idea on what might have caused the leaf curl and drop? I'll post a few photos soon.

About ready to add some mulch fertilizer to the citrus trees

Just bought a few bags of composted steer manure to add around the citrus trees this weekend. I wanted to buy some chicken manure, but Lowe's doesn't  seem to sell it. I'll post more imagesof this process as I  will be removing the 3/4" rockmulch that is there now  and replacing it with this organic style ofading nutrients in addition to being a mulch for better water conservation.

Enjoy the weekend and remeber when it comes to established citrus, (two years in the ground or longer), you want to fertilize three times per year - Valentine's Day, Memorial Day and Labor Day.
