roofgardencairo Cairo, Egypt Jul 10, 2011

Hello,

I'm new to gardening and I'm trying to set up a potted rooftop garden on my very hot, very sunny roof in Cairo, Egypt. There is almost no shade throughout the day. The air is fairly dry, dusty, and polluted. The water, I believe, has a high mineral and chlorine content. I have a variety of plants, not all of which I've been able to identify. I'm watering all of them every night; then I mist them with a spray bottle (because the climate here is fairly dry). The problems:

- The leaves on the regular bougainvillea vines appear to be wilting.
- A smaller more spindly bougainvillea (or what I was told was a kind of bougainvillea) has turned completely yellow and wilted. It's in a clay pot and the soil is very firm.
- Some of the leaves on the African jasmine have turned from evergreen color to a paler kelly green
- There's another tree that I think may be related to jasmine (it has very small white, fragrant flowers), and that tree is looking very dry-- a few branches have died. The flowers have dried up and fallen off. I'm wondering if it's not able to handle the sun...
- The tips of my yuccas have turned brown and dry.

Help!
