1. Start with the sightline, not the fence

Stand in the spot where you actually want privacy — the patio chair, the pool edge, the bedroom window. Look at what you want hidden. That line, and where it crosses your boundary, tells you the height you need.

The result is frequently different from what people assume. Blocking a neighbour’s ground-floor window may need six feet. Blocking a second-floor window from a patio twenty feet away may need considerably more than any hedge will deliver — which is worth knowing before you spend.

If the honest answer is that a hedge cannot fully solve it, layering with a small tree or a structure is a better conversation than a hedge that disappoints.

2. Height, width and what you have room for

Once you know the height, check you have the depth for it. A hedge tall enough to screen is also going to be wide.

  • Clusia wants real width — three feet of bed depth minimum, more comfortably.
  • Podocarpus stays narrower, which is why it suits tight side yards.
  • Areca palm clumps outward and needs the most room of the three.

Allow two to three feet between the hedge and the fence for airflow and access. See hedge spacing.

3. Choosing the species

Work through in this order:

  1. How much sun does the line get? Under four hours, clusia will disappoint. Arboricola holds up better in shade.
  2. How exposed to salt? Near the bay, cocoplum and clusia over podocarpus.
  3. How formal? Podocarpus for a clipped architectural wall, clusia for a fuller natural screen.
  4. How much maintenance? All of the above beat ficus comfortably on this measure.

4. Time versus budget

Two levers control how fast you get privacy, and both cost money.

Starting size. Buying taller stock buys you time directly. A 7-gallon hedge screens sooner than a 3-gallon one, immediately.

Spacing. Tighter spacing closes the gaps sooner, at more plants per foot.

Of the two, starting size usually gives better value. Larger plants at sensible spacing frequently beat small plants packed tight for similar money.

5. Practical checks before you order

  • Locate utilities before digging. Free to check, expensive to hit.
  • Confirm the property line. A hedge planted a foot inside the boundary will be over it within a few years.
  • Check HOA or city rules — height limits and approved species are common, and Coral Gables regulates more closely than most.
  • Test drainage along the run. One wet section will show as a gap in the hedge.
  • Plan irrigation before planting, not after.

Stand where you want privacy and take a photo of what you want blocked. Send it with the run length and we can plan the screen properly. Send it over.

Frequently asked questions

How tall does a privacy hedge need to be?
It depends on the sightline. Stand where you want privacy, look at what you want blocked, and measure where that line crosses your boundary. Blocking a ground-floor view often needs around six feet; blocking an elevated view needs considerably more.
How long does a privacy hedge take to fill in?
With clusia in full sun at 2–3 feet spacing, typically one to two seasons from 3-gallon stock. Larger starting stock screens immediately.
Can I plant a hedge right against my fence?
Better not to. Allow two to three feet for airflow behind the hedge and access to trim the back, and more for wide species like clusia.
Do I need permission to plant a hedge in Miami-Dade?
Planting is usually straightforward, but HOAs and some municipalities regulate height and species, and Coral Gables regulates landscape alterations more closely. Check before ordering.
