About Yukon Gold Potato

Solanum tuberosum 'Yukon Gold' · also called Yukon Gold potato, yellow-fleshed potato · edible

Yukon Gold is a popular early-to-mid-season potato with thin yellow skin and buttery yellow flesh that holds together well, making it excellent for mashing, roasting and boiling. A cool-season tuber crop, it needs full sun, loose acidic soil and steady moisture, and is harvested about 80-95 days after planting seed potatoes.

Cold limit: USDA 3-9 (frost-sensitive cool-season annual; plant after danger of hard frost) · RHS H2 (foliage frost-tender) (15-20°C (tubers form best with soil 15-18°C; growth slows above 27°C))

What yukon gold potato's hardiness rating actually means

Hardiness works differently for yukon gold potato: it is grown as a seasonal crop, not overwintered. The question is not "what zone" but "how long is your frost-free growing window". Its RHS rating of H2 means: Tender — survives a frost-free greenhouse or a very mild, sheltered spot. On the US scale that maps to USDA 3-9 (frost-sensitive cool-season annual; plant after danger of hard frost) — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

As an annual crop, its "minimum temperature" is the first hard frost — that is the end of the plant's life, not a survivable low. Many types are also damaged by light frost (around 0 °C).

Concretely, for yukon gold potato as it gets too cold:

Light frost (around 0 to −2 °C) damages or kills tender summer crops outright; cold-hardy types take a few degrees of frost.
The plant does not "survive winter" — its life cycle simply ends, by design, when frost arrives or it finishes cropping.
A surprise late spring frost can also kill young transplants set out too early, before the season even starts.

Can yukon gold potato go outside or overwinter — and where?

Time it to your frost dates: sow or plant out after the last spring frost, and aim to harvest before the first autumn frost.
In short-season zones, start it indoors or under cover to stretch the effective growing window.
Hardier crops in this group can be sown for an autumn or overwintered harvest in mild zones — check the specific crop.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when yukon gold potato can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H2 figure above.

Frost protection for borderline yukon gold potato

Yukon Gold Potato is right on a hardiness edge in many gardens, so if you are pushing it, these measures buy it the margin it needs:

Use fleece, cloches or a cold frame at each end of the season to dodge a borderline frost and add growing weeks.
Have row cover ready for an unexpected late spring or early autumn frost.
Know your local last- and first-frost dates and count back the crop’s days-to-maturity to schedule the sowing.

Yukon Gold Potato hardiness — frequently asked questions

Is yukon gold potato cold hardy?

Hardiness works differently for yukon gold potato: it is grown as a seasonal crop, not overwintered. The question is not "what zone" but "how long is your frost-free growing window". A seasonal crop, not a perennial. Yukon Gold Potato is grown 3-9 (frost-sensitive cool-season annual; plant after danger of hard frost); you sow after the last frost and harvest before the first one, then start again next year.

What is the minimum temperature yukon gold potato can survive?

As an annual crop, its "minimum temperature" is the first hard frost — that is the end of the plant's life, not a survivable low. Many types are also damaged by light frost (around 0 °C).

What hardiness zone is yukon gold potato?

Yukon Gold Potato is rated USDA 3-9 (frost-sensitive cool-season annual; plant after danger of hard frost) and RHS H2 — Tender — survives a frost-free greenhouse or a very mild, sheltered spot.

Can yukon gold potato survive winter outside?
