I'm in a situation where its a waste of time, effort and money to take care of our many little gardens (Different separate gardens ranging between 20-90 meters square). Briefly, we rarely visit them and its is nearly impossible to be available to take care of them the whole year. We could be available only a few weeks a year !!!
Also we don't have access to good water. But we can use underground water which is very bad for the grass so we mainly use for other purposes. It's a rainy area during winter.
Basically these gardens are in coastal-desert areas so in summer its extremely hot and dry during day and very nice during night and in winter its extremely cold during night and very nice during day.
I'm mentioning these conditions because I'm looking to replace these gardens with something that could be useful or at least not harmful to cope with during very hot and dry conditions or very cold conditions.
Hopefully I was clear enough. Thank you for your time.
