Sisal Hemp is grown for its foliage and the structure it brings to a planting. It's hardy across USDA zones 9 through 11. Its spring flowers are a moderate draw for native bees and moths.

What Sisal Hemp is
It blooms in spring.
How to grow Sisal Hemp
Sisal Hemp grows in USDA zones 9 through 11. Sisal Hemp does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.5 to 8, on well-drained ground. It needs a growing season of at least 150 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant sisal hemp in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Sisal Hemp prefers pH 5.5 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.
Keep it in good form
Prune sisal hemp to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Where Sisal Hemp thrives
Sisal Hemp 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 Sisal Hemp stands, state by state
Sisal Hemp 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.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

How we know this about Sisal Hemp
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Sisal Hemp in my zone?
Sisal Hemp grows in USDA hardiness zones 9 through 11 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Sisal Hemp?
Most growers plant sisal hemp after the last spring frost, once the soil has warmed, leaving enough of the season for its 150-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Sisal Hemp need?
Sisal Hemp needs full sun — a spot that catches at least 6 hours of direct summer sun a day. 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 Sisal Hemp need?
Sisal Hemp prefers soil pH 5.5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Sisal Hemp attract pollinators?
Yes — sisal hemp's flowers are a solid nectar source for native bees and moths.
Is Sisal Hemp safe for pets?
Sisal Hemp is toxic to pets (dogs,cats) with mild severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
