The answer
Here’s what actually matters.
New landscaping needs more care at the beginning than an established yard. Fresh sod and newly installed plants must stay consistently moist while roots establish, then watering should taper rather than continuing at establishment frequency forever.
Florida licensing boundary
Who must handle the regulated work.
Ordinary landscape cleanup and planting are different from regulated utility work. Florida DBPR says compensated irrigation installation that requires connecting lines to potable water needs a licensed contractor, while installing or repairing an irrigation system that already has a backflow preventer connected to the potable supply is listed differently. Any electrical, plumbing or other regulated portion of a landscape project must go to the appropriately licensed trade.

For new sod
UF/IFAS guidance for newly installed sod uses frequent, short irrigation at first, then tapers as the turf roots in. The exact runtime depends on irrigation output, weather, soil and local watering rules, so minutes on one property do not transfer perfectly to another.
For new plants and beds
Water the root zone deeply enough to support establishment without leaving the soil continuously saturated. Plant size, species, soil and sun exposure matter; drought-tolerant does not mean “no establishment watering.”
What to watch instead of blindly following a timer
- sod edges drying or lifting
- wilting plants
- standing water or persistently soggy soil
- irrigation missing parts of the new installation
- runoff onto hard surfaces
Bottom line
Installation is not finished when the crew leaves. The handoff should tell you who waters, for how long establishment care is expected, and when to transition to normal maintenance.
