Which other evergreen trees go well with Little Gem Magnolias
I have about 8 little gem magnolias along a fence line to have a privacy screen along the edge. The 7 ft trees were planted about 5 ft apart, 2 years ago. They are about 8 ft tall now. Looks like these magnolias will not provide privacy screen soon and am looking for a 18 ft screen.
Can I include any other fast growing evergreen tree in between these magnolias? If so, which ones go well. Please suggest a few evergreens for Zone 7b. that need very little maintenance.
I was thinking about Carolina Laurel Cherry or Red tip photonia or Ficus Nitida (a.k.a Indian Laurel) or a holly. However Ficus Nitida seems to grow very big, needs lotsa trimming and are also invasive. I am not sure if they sustain DFW area weather. Whereas, Photonias are susceptible to rust disease. Any suggestions?
