[Arid_gardener] Question from Home-Hort WWW page

[Chris Trask]

     This sounds a bit like either zinc or iron deficiency.  Desert soils are notorious for these problems as the alkalinity keeps these and other nutrients from becoming soluble.  You might consider working in some zinc sulfate and iron chelate into the sorrounding soil and then applying a diluted solution of Fertilome (sp?) soil acidifier.

>Three weeks ago I had my backyard landscaped. I had a variety of plants (bougainvillea, cape honeysuckle, desert spoon, yucca, orange jubiliee, and a dwarf citrus tree) planted along my back south wall, which faces north. The "Superstition Gold" Bougainvillea's leaves are limp and have turned light green / yellow and are falling off. I have the irrigation system set for 45 minutes every 3 days, as directed by the landscaper.  The other plants seem to be doing OK - although another Bougainvillea's leaves look like they have some kind of water spotting on them and are also kind of limp. What can I do to keep from losing the Gold Bougainvillea? (The plants are all on the same line, but the tree has 3 emitters.) Pam
