Plant it right
Set red river gum southern provenances in full sun with evenly moist to well-drained soil.
Match the soil
Red River Gum Southern Provenances prefers pH 4.5 to 8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Shape it while it is young
Prune red river gum southern provenances only to remove dead, damaged or crossing branches while it is young; it is grown for its form, not a harvest, so little more is needed once it settles in.
Where Red River Gum Southern Provenances thrives
Red River Gum Southern Provenances is hardy across USDA zones 9 through 11. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 9–11 spans average winter lows from 20°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 17 down the middle — and which side of that line your land sits on changes the answer.

Where Red River Gum Southern Provenances stands, state by state
Red River Gum Southern Provenances is rated for zones 9–11 — a cold floor USDA puts at 20 to 30°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 17 more, and 34 sit outside it — and inside every split state, the same line runs on at county grain.

Frequently asked questions
Can I grow Red River Gum Southern Provenances in my zone?
Red River Gum Southern Provenances grows in USDA hardiness zones 9 through 11 (Rated hardy to zone 9a by Cal Poly SelecTree; Tropical Plants Database (Useful Tropical Plants) lists -7 °C, converted to zone 9a; USDA PLANTS Database lists 17 °F, converted to zone 9a, checked Oct 2026. Ceiling: our plant database.). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Red River Gum Southern Provenances?
Set red river gum southern provenances out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.
How much sun does Red River Gum Southern Provenances need?
Red River Gum Southern Provenances needs full sun — a spot that catches at least 6 hours of direct summer sun a day. We haven't confirmed this against a published source yet. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Red River Gum Southern Provenances need?
Red River Gum Southern Provenances prefers soil pH 4.5 to 8, on evenly moist to well-drained ground (FAO ECOCROP). Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Red River Gum Southern Provenances attract pollinators?
Yes — red river gum southern provenances's flowers are a strong nectar and pollen source for honeybees and native bees. We haven't confirmed this against a published source yet.
Is Red River Gum Southern Provenances safe for pets?
