Ficus Nitida They’re fast-growing, upright, and evergreen. This means they are green all year round. Plant them 2 – 3 feet apart in a row to create a full privacy hedge. Use Ficus to block a view, create a border, or even reduce noise. Ficus have very aggressive root systems, which is why they grow so fast. Be careful when planting near a wall or pavement, as they can possibly cause damage if allowed to grow large overtime.
