Gardening in Deltona-Daytona Beach-Ormond Beach, FL
This metro spans USDA zones 9b to 10a, so there is no single zone for Deltona-Daytona Beach-Ormond Beach, FL and anyone who gives you one is rounding. 74% of its ZIP codes are zone 9b; the rest are not.
Which zone you are in depends where you are
Deltona-Daytona Beach-Ormond Beach, FL covers 2 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it — which is fine for the 74% in zone 9b and wrong for the other 26%. Here is the actual split.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 9b | 23 | 74% | |
| 10a | 8 | 26% |
Zones are published per ZIP code, so yours is exact even though the metro's is not. The hardiness tool will tell you which one you are in.
Your freeze dates
No freeze range is shown for Deltona-Daytona Beach-Ormond Beach, FL, because the freeze window here crosses New Year, so an earliest-to-latest range would be arithmetic on dates that do not sit in order. The tools below still answer for individual ZIP codes here, and will say what applies.
Your growing season
NOAA publishes a growing-season length for each station, and across the 9 stations serving Deltona-Daytona Beach-Ormond Beach, FL it runs 310–365 days . That figure is published, not computed from the two freeze dates — subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 87–92 °F , at or above the 90 °F point where cool-season crops bolt and tomato and pepper pollen fails — so midsummer sowings of lettuce and its relatives are worth holding here.
What survives the winter changes across Deltona-Daytona Beach-Ormond Beach, FL
Of 74 perennial fruits, nuts, berries, vegetables and herbs, 40 come through the winter in zone 9b and only 25 in zone 10a. That is a different garden at each end of the same metro.
| Zone | ZIPs | Survive | Fail for being too warm |
|---|---|---|---|
| 9b | 23 | 40 of 74 | 32 |
| 10a | 8 | 25 of 74 | 49 |
The last column is the counterintuitive one, and it is why the totals do not simply rise as the winters get milder. Most temperate fruit needs a documented number of hours below about 45 °F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the summer heat that comes with it.

Where these numbers come from
The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates are NOAA's 1991–2020 Climate Normals, read from every station whose normals cover a ZIP code in this metro. Nothing here is estimated, and no station stands in for another.
This page names no single station on purpose. Picking one to represent a metro sounds reasonable and is not: the station serving the most ZIP codes is an artifact of where ZIP centroids happen to fall, and it selects a lock on the Monongahela for Pittsburgh and a far southern suburb for Chicago. A range across every station is true; a single cited date for a whole metro is not.
