Consecrated garden area containing fewer (7)
I believe the answer is:
blessed
'consecrated' is the definition.
('bless' can be a synonym of 'consecrate')
'garden area containing fewer' is the wordplay.
'garden area' becomes 'bed' (as in a flower bed).
'containing' means one lot of letters goes inside another.
'fewer' becomes 'less' ('less' is associated in meaning with 'fewer').
'bed' enclosing 'less' is 'BLESSED'.
(Other definitions for blessed that I've seen before include "Highly favoured or fortunate" , "Endowed" , "Sanctified" , "worthy of respect" , "Happy; beatified" .)
