1. Start with the sightline, not the fence
Almost everyone plans a hedge along the boundary. The boundary is rarely the thing that needs blocking.
Stand where you actually want privacy — the patio chair, the pool edge, the bedroom window. Look at what you want hidden. Where that line crosses your property tells you the height you need, and it is frequently different from what people assume.
Blocking a ground-floor window might need six feet. Blocking a second-floor window from a patio twenty feet away may need more than any hedge will realistically deliver — and knowing that before you spend saves a great deal of disappointment. Full method in our privacy screen planning guide.
2. The four species worth considering
Clusia. Thick paddle-shaped glossy leaves, genuinely opaque, handles salt, wind, heat and drought, tolerates being cut back hard. Wants real depth though — under about three feet of bed you will be fighting it.
Podocarpus. Fine needle-like foliage that takes and holds a crisp clipped edge. Slower, so buy taller or wait. Stays narrower, which makes it the answer for tight side yards. Only moderate salt tolerance.
Cocoplum. Florida native, exceptional salt tolerance, low water once established. The right choice on genuinely exposed coastal sites.
Variegated arboricola. Gold-and-green foliage that holds colour under canopy where sun-loving hedges thin out. The shade answer.

3. Spacing decides the timeline and the bill
Two levers control how fast you get privacy, and both cost money.
Starting size buys time directly. Larger stock screens sooner, immediately, on day one.
Spacing closes the gaps sooner at more plants per foot. On a sixty-foot run, moving from three-foot to two-foot centres takes you from twenty-one plants to thirty-one — roughly half again the plant cost — to close perhaps one season earlier.
Of the two, starting size usually gives better value. Larger plants at sensible spacing frequently beat small plants packed tight for similar money. Ask us to price both and compare. Full numbers in the spacing guide.
4. A word on ficus
Ficus grows faster than anything else here and makes a beautiful dense wall. It is also responsible for a great deal of hedge regret across South Florida.
Aggressive roots that damage foundations, driveways and pool decks. Trimming every four to six weeks in growing season. Whitefly pressure that has caused significant defoliation regionally. And a plant that fundamentally wants to be a very large tree and never forgets it.
With budget for regular professional maintenance and real distance from hardscape, it performs. Most homeowners are better served by clusia, and we would rather say so.
5. The coastal and salt-exposed cases
Some Miami-Dade properties sit close enough to open water that salt spray, not sun or soil, is the deciding factor. On those sites the species list narrows.
Cocoplum is the safest choice for genuinely exposed, beachside positions. It is a Florida native, tolerates salt as well as anything we grow, and asks for very little water once its roots are down. It clips into a solid green screen and shrugs off wind.
Silver buttonwood gives you the same salt tolerance with a different look — soft silvery-grey foliage that can be left loose as a screen or clipped tighter. It handles wind and exposure well and brings a colour most hedges cannot.
Clusia also earns its place here: its salt tolerance is high enough for most near-coastal gardens that are not directly on the sand, which is one more reason it is our default recommendation across the county.
If your property is exposed, tell us how close you are to open water and which way the prevailing wind comes from. That decides whether we point you to cocoplum, silver buttonwood or clusia — all three grown here, all three salt-ready.
Measure the run, the available depth, and how fast you need cover. Those three numbers determine species, size and spacing. Send them over.
