Dear Sir, This is the first log-in to this site, I have a small garden directly by the red sea as a resort, it is 600 m2 surrounding my villa at Ras Sudr, South of Sinai, Egypt, the soil is salty as well as the gardening water, therefore the plants and the grace are week and pale, please advise which plants and flowers can live there, how can I simply treat the water, ...etc. Best regards Hossam El Hosseiny
I would suggest you inquire at local garden centres, or even the university there, as they would know the degree of saltiness involved (though almost any is usually a problem), which plants are most tolerant of it, and which will grow well there in the specific environment - plus you could advance Google 'salt-tolerant' plants for tropical(?) climates.
You might find this article to be of interest - it mentions a number of plants being grown under high salinity conditions: Use of Permaculture Under Salinity and Drought Conditions
