The 2026 windows

Sweet Potatoes dates for a typical Virginia season.

1 · Start indoors

Apr 5 to May 16

About 6 weeks before set-out. Warm spot, real light.

2 · Set out

May 17 to Jun 27

Keyed to the ~Apr 10 last frost. Sow 3" deep, 14" apart.

Harvest

~110 days later

~2.5 lb per plant over ~1 weeks.

Virginia spans more than one climate: Zone 7 is the most common zone, but the state runs 6b to 8a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.

Virginia growing notes

The Nansemond is Virginia's own sweet potato, and it still grows well here.

A named variety with roots on the Nansemond River

Long before Beauregard became the standard sweet potato in most seed catalogs, Virginia growers along the Nansemond River in the Tidewater region kept their own strain going, a variety that seed savers and heirloom catalogs still list today under the Nansemond name. It is not the highest-yielding option on the market anymore, but it is well suited to exactly the sandy, warm coastal soil it was selected on for generations, and growing it is as much a nod to the region's own farming history as it is a practical variety choice.

Beauregard remains the more productive pick for a gardener prioritizing yield over history, bred for uniform size and reliable performance across a wide range of soils. Either variety wants slips set once the soil has warmed well past the point tender transplants can tolerate; sweet potato is genuinely more heat-loving than the potato it shares half a name with, and a slip set too early simply sits and sulks rather than growing.

Curing is not optional, and refrigeration ruins the crop

Freshly dug sweet potatoes taste bland and starchy, almost nothing like the sweet, dense roots sold at a grocery store, because that sweetness only develops during curing. Hold roots at roughly 85 degrees and high humidity, in the 90 to 95 percent range, for 4 to 7 days right after digging; a cardboard box in a warm room with a damp towel draped nearby approximates it well enough for a home harvest. That short window converts stored starches into sugars and is the single step most home gardeners skip and most regret skipping.

Once curing finishes, hold roots in the 55 to 60 degree range and skip the refrigerator entirely; cold storage below that range damages sweet potato flesh in a way that shows up as a hard, woody core once cooked, even though the outside looks fine. A cool closet or an unheated but frost-free room in a Virginia home usually holds that range through most of the storage season without any special equipment.

A potato bed's troubles mostly don't follow sweet potato home

Sweet potato escapes most of what troubles a regular potato patch, Colorado potato beetle included, since the beetle feeds only on the nightshade family and sweet potato is not in it. The pests that do matter here are sweet potato weevil and deer, plus aphids on young growth. A weekly look at the undersides of leaves, followed by handpicking, keeps aphids from building before harvest.

Late blight goes further than just sparing sweet potato some damage: the fungus infects potato and tomato only, and sweet potato, a member of the morning glory family rather than the nightshade family those two belong to, is not a host at all. A gardener rotating beds to manage blight in a nearby tomato patch gains nothing by extending that same rotation discipline to sweet potatoes, since there was never any blight risk there to rotate away from.

In Virginia: watch for

The pests that find sweet potatoes here.

A middle-length season, about 202 frost-free days, means sweet potato overlaps wireworms & white grubs for a stretch each summer. Check plants every week or two and treat early.

Wireworms & white grubs

Shallow holes and grooves chewed into the roots, found only at digging time.

Organic fix: Avoid planting into ground that was in sod last year; rotate away from grassy beds.

Aphids

Clusters on the tender growing tips of new vines.

Organic fix: Hose them off in the morning, or use insecticidal soap.

Black rot

Dry, firm dark patches on the roots, usually found at harvest or in storage, with a sweet fruity smell.

Organic fix: Start from clean slips cut well above the soil line, never save roots from a bad crop, and rotate 3 years.

Your season math: Virginia gives sweet potatoes about 202 frost-free days, and it needs roughly 110 days to a first harvest. It's a one-planting crop, so time that single sowing well.
