Devils Tongue Yellow Hot Peppers

Prolific · Solanaceae

Devils Tongue Yellow carries long, wrinkled 2-3 inch fruits that ripen from light green to bright yellow to golden yellow. It is a fiercely hot chinense pepper, commonly described around 125,000-325,000 SHU, with a sweet, citrusy flavor that makes vivid hot sauces and pickles. This rare heirloom is often linked to Amish selection in Pennsylvania and is prized for very heavy production once plants reach full summer heat. Key facts: 90–110 days to maturity, 8+ hours of sun, 18–24 " spacing. Can be grown in containers with care (5+ gallon minimum). Requires stake for best results.

Common Issues

Blossom Drop

Cause: Temperature extremes or inconsistent watering

Prevention: Maintain even moisture. Shade cloth in extreme heat.

Aphids

Cause: Soft new growth attracts aphid colonies

Prevention: Companion plant with basil. Spray with neem oil if severe.

Blossom End Rot

Cause: Calcium transport disruption from inconsistent watering

Prevention: Consistent watering + Cal-Mag at flowering stage

What you'll need

Growing Supplies

Based on Devils Tongue Yellow'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.
