Thickening Ficus Hedge in Rocky Soil: Amend and Fertilize

Root Zone Improvement Is Key

100 ficus trees (6 ft) planted 2 yrs ago in S. California rocky soil. Grew 2 ft taller but thin, no privacy. Two thickened. Some yellow.

Two-Part Solution

1. Soil Amendment: Add compost + topsoil to beds. Slowly changes profile.
2. Fertilize Spring: Balanced fertilizer + organic biostimulants. Addresses yellowing and density.

Why It Works

Rocky soil limits root expansion and nutrient holding. Amendments create better root environment. Biostimulants enhance root function.
