About Pecan 'Cape Fear'

Carya illinoinensis 'Cape Fear' · also called Cape Fear pecan · edible

'Cape Fear' is a vigorous, fast-growing pecan cultivar popular in the southeastern US for early production and good scab tolerance for a type-I (protandrous) pollinator. It needs a long, hot growing season, deep well-drained soil and a type-II pollenizer such as 'Stuart' for cross-pollination. The large, well-filled nuts ripen in autumn.

Cold limit: USDA 6-9 · RHS H4 (-23 to 40°C)

Watch for — Pecan weevil and nut casebearer: These pests bore into developing nuts, causing drop and damaged kernels. Monitor and time controls to their life cycles; orchard sanitation reduces overwintering populations.

What pecan 'cape fear''s hardiness rating actually means

Its RHS rating of H4 means: Hardy in an average winter across much of the temperate world. On the US scale that maps to USDA 6-9 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −10 to −5 °C. Pecan 'Cape Fear' is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for pecan 'cape fear' as it gets too cold:

It tolerates winter lows to about −10 to −5 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can pecan 'cape fear' go outside or overwinter — and where?

Plant it out within USDA 6-9 and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

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 pecan 'cape fear' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H4 figure above.
