Fillers for 'Smaragd' privacy hedge in its early stage
Have a row of 2.5 - 3ft tall 'Smaragd' Arborvitae that we hope will eventually serve as a privacy hedge. They are spaced about 2 feet apart. While they currently dont provide much privacy in either height or width , are there any recommendations for temporary filler plants to between the arborvitaes while we wait for them to grow tall and wide? Thank you!
