Lovely suggestion.
It was already nice to see Mavis and Bill (keen gardens) and their adjoining neighbours on North facing Phase 1 getting their flowers on display.
Can appreciate why the communal landscaping has not used grass in the central area's but it would have given a softer appearance - no doubt once the trees they have planted become more established it will look lovely.
In the developers complex near Murcia, they incorporated fountains - this again added to the feel of the place.
It is difficult when you are not there all the time to have plants thrive, but there is also watering systems which are fairly reasonable to install which can be considered.
Must log off before people get the impression we are keen gardeners!
