Generally — Most Areas
red oak (zones 3-8) partially overlaps with Massachusetts (5a-7b). It can grow in zones 5-7 within the state.

Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Red Oak wants 0+ frost-free days; a typical Massachusetts site sees ~170 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Chill hours
Red Oak requires ~1000 chill hours (32-45°F dormancy window). Massachusetts typically banks ~1500 chill hours per winter (MSU Extension method), which keeps this plant on track.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Red Oak likes near-neutral soil (pH 5-7). That's the common-ground band across Massachusetts's glacial till and sandy loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Massachusetts site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Red Oak in Massachusetts — Quick Answer
- Verdict: Generally — Most Areas
- Plant Zones: 3-8 (USDA PLANTS Database)
- State Zones: 5a-7b (USDA ARS PHZM 2023)
- Growing Season: Apr 10 - May 20 to Sep 20 - Oct 30 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Massachusetts growers also need to think about:
Short growing season (120-180 frost-free days) limits warm-season crops
Rocky glacial soils require amendment in many areas
Late spring frosts can damage early plantings through mid-May
Deer pressure is significant in suburban and rural areas
Massachusetts Cooperative Extension
For Massachusetts-specific cultivar recommendations, planting calendars, and pest pressure for red oak, the canonical source is UMass Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
