Ficus Nitida (Retusa) Hedge spacing advice please.
Planning on making a 15 ft + wall with Ficus Nitida to block out neighors view of our yard. They have recently extended their kitchen that literally looks over our whole yard as if it their own. Already have a 6ft fence which is just for formality and need atleast 12+ ft to block them out completely. Decided to go with Ficus Nitida to cover a 120 ft stretch.
The size i'm purchasing is a 15 gallon size which are about 7ft tall with 2" tree diameters approximately 20 of them.
Can someone who has experience with hedge spacing give me advice with these particular species?
The stretch is on a slope so each plant will be planted with a deep water tube.
Thanks in advance.
