Sizzler Deep Red is a compact, early-maturing bell pepper variety known for its vibrant deep red color and sweet flavor. It produces prolific yields of medium-sized peppers on bushy, determinate plants ideal for containers and small spaces. The peppers transition from green to deep red as they mature, offering excellent flavor at both stages.

📏
Spacing: 18-24 inches apart, with rows 24-30 inches apart inches
📅
Days to maturity: 60-90 days from transplant to first ripe peppers (green stage 50-70 days, full red color 70-90 days)
🌱
Planting depth: 1/4 inch for seeds; transplants set at same depth as original containers

Growth Stages

1

Seedling

4-6 weeks

Germination occurs in 7-14 days at 70-85°F. Seedlings develop true leaves and strengthen.

Maintain 70-80°F with high humidity. Provide grow lights 14-16 hours daily. Keep soil moist but not soggy. Thin to strongest seedlings.

2

Vegetative Growth

3-4 weeks

Plants develop bushy foliage with multiple stems. Sizzler varieties are naturally compact and branch readily.

Harden off transplants gradually over 7-10 days before planting outdoors. Maintain consistent watering and warmth (65-75°F nights). Pinch center stem if desired to encourage bushiness.

3

Flowering

4-5 weeks

Small white flowers appear in clusters at branch tips. Peppers are self-pollinating but benefit from wind or gentle hand pollination.

Maintain warm temperatures (70-85°F). Ensure adequate light and consistent moisture. Do not overwater (reduces flower retention). Apply balanced or phosphorus-rich fertilizer. Gently shake plants or brush with small brush to improve pollination.

4

Fruiting & Development

4-6 weeks

Small green peppers form and rapidly enlarge. Peppers reach harvest size (green) within 3-4 weeks, then continue developing color.

Water consistently as fruit size affects quality. Provide support for branches if heavily laden. Continue balanced feeding every 2-3 weeks. Remove any diseased fruit immediately.

5

Ripening & Harvest

3-4 weeks (ongoing through season)

Peppers transition from green to deep red, developing fuller sweetness and optimal color. Sizzler Deep Red typically produces abundant peppers on compact plants.

Harvest green peppers anytime (will ripen indoors). For deep red color, leave on plant 2-3 additional weeks. Pick regularly to encourage continued production. Water and feed consistently until frost.

Common Pests

  • Spray with insecticidal soap or neem oil; encourage beneficial insects like ladybugs; spray strong water stream to dislodge.

  • Mist plants regularly to increase humidity; spray with neem oil or insecticidal soap; apply sulfur dust if severe.

  • Remove and destroy infested peppers; use row covers early; apply spinosad or carbaryl if necessary; practice crop rotation.

  • Use yellow sticky traps; spray with neem oil or insecticidal soap; encourage natural predators; avoid excess nitrogen fertilizer.

  • Improve air circulation; avoid overhead watering; spray with sulfur dust or potassium bicarbonate; remove affected leaves.

Uses

🍳

Fresh eating and salads

Culinary

Sizzler Deep Red peppers have sweet, crisp flesh ideal for raw consumption in salads, slaws, and vegetable platters. The deep red color adds visual appeal and indicates maximum sweetness and nutritional content. [source]

🍳

Stir-frying and roasting

Culinary

The compact fruit size and manageable plant height make Sizzler varieties excellent for home cooking. Peppers are perfect for stir-fries, fajitas, roasting, and stuffing. [source]

🍳

Preservation and processing

Culinary

Deep red color and sweet flavor make these peppers excellent for freezing, drying, or making pepper paste. High yields mean abundant produce for preservation projects. [source]

💊

Nutritional benefits

Medicinal

Red peppers are rich in vitamin C (more than green peppers), antioxidants, and capsaicinoids with potential anti-inflammatory properties. A single red pepper provides 150% of daily vitamin C requirement. [source]

🦋

Pollinator attraction

Wildlife

Bell pepper flowers attract bees and other pollinators, supporting garden biodiversity. The abundant blooms benefit the entire garden ecosystem. [source]

Harvest Tips

Begin harvesting green peppers 50-70 days after transplanting; for deep red color (Sizzler's signature), wait additional 2-3 weeks. Cut peppers with 1-inch stem using sharp knife or pruners to avoid plant damage. Pick regularly to encourage continued flowering and fruiting. Peppers harvested green will slowly ripen at room temperature if desired. Frost will kill plants, so harvest all remaining peppers before first freeze.

Fun Facts

  • 🌱 Sizzler Deep Red is specifically bred for compact growth (12-18 inches) and early maturity, making it one of the fastest-maturing bell pepper varieties available for home gardeners.
  • 🌱 Bell peppers are technically berries botanically, with the fruit developing from a single flower's ovary and containing seeds; they're one of the few vegetables that are scientifically fruits.
  • 🌱 The transition from green to red peppers isn't a ripening process like tomatoes—the red pigment (lycopene and other carotenoids) gradually accumulates as chlorophyll breaks down, and the peppers become sweeter and significantly more nutritious.
