Beauregard Sweet Potato

Convolvulaceae

Most widely grown US sweet potato. LSU release. Early-maturing at 90-105 DTM — critical for northern/marginal zones. Red-orange skin, deep orange flesh, moist texture. High-yielding. Disease-resistant (soil rot, Fusarium wilt, moderate root-knot nematode resistance). Requires slips (vine sprouts), NOT seeds or tuber pieces. CURING MANDATORY — uncured sweet potatoes taste starchy, not sweet. Harvest BEFORE first frost. Key facts: 90–105 days to maturity, 8+ hours of sun. Not recommended for containers.

Growing Supplies

Based on Sweet Potato (Beauregard)'s growth profile -- recommendations matched to this variety's specific requirements.

Drip irrigation / soaker hose kit

Every gardener benefits from putting water at the root zone instead of on the leaves, because drip and soaker systems reduce foliar disease pressure by limiting leaf wetness and soil splash. A quality kit should include a backflow preventer, filter, pressure reducer, and UV-resistant tubing.

Soil test kit

A soil test gives a baseline for pH and nutrient status so gardeners can add only what the soil actually needs. Prioritize a mail-in or lab-affiliated kit whenever possible because extension guidance notes that laboratory testing is more accurate than instant readers.

Quality bypass pruners

Extension guidance favors bypass designs because they make cleaner, closer cuts on living tissue than anvil types. Look for hardened steel blades that can be sharpened, a comfortable grip, and a cutting capacity matched to real home-garden stems.
