Growing Guide Details

Plant Classifications

Peppers fall into two main categories based on heat level. Sweet peppers produce mild, flavorful fruit ideal for fresh eating, stuffing, or cooking. Hot peppers contain varying levels of heat and are commonly used for sauces, drying, or spice. Within these groups, peppers vary widely in size, shape, color, and maturity time.

What Variety to Choose?

💡

California Wonder: Classic sweet bell pepper with thick walls and dependable yields.

King Arthur: Large, blocky green-to-red bell pepper with excellent productivity.

Jalapeño: Reliable medium-heat pepper great for fresh use or pickling.

Cayenne: Long, thin hot pepper ideal for drying and making pepper flakes.

When to Plant

Indoor Start:
Start pepper seeds indoors 8–10 weeks before your last expected frost date. Peppers germinate slowly and benefit from warm soil and a long head start.

Outdoor Transplant:
Transplant outdoors only after all danger of frost has passed and nighttime temperatures consistently stay above 55°F. Peppers are cold-sensitive and will stall in cool soil.

Light & Space Requirements

Sunlight:
Peppers thrive in full sun. In hot climates, light afternoon shade can reduce heat stress and sunscald on fruit.

In-Ground Spacing:
Row spacing: 24–36 inches

Plant spacing: 18–24 inches

Good spacing improves airflow and reduces disease pressure.

Raised Beds & Containers:

Use containers at least 5 gallons in size. Compact or smaller-fruited varieties perform best in pots.

Planting Depth:
Transplant peppers at the same depth they were growing indoors. Planting too deep can slow growth.

Soil & Fertility

Soil Requirements:

pH between 6.2–6.8

Rich in compost or organic matter

Well-draining, loamy soil

Fertilizer Schedule:

Before Planting:
Mix 1½ cups of HOSS Complete Organic Fertilizer per 10 ft of row

2 Weeks After Transplanting:
Side-dress with 2 cups of HOSS Complete Organic Fertilizer per 10 ft row.

If using Fertilizer injector, 1 cup 20-20-20 Fertilizer and 1-2 cups microboost per 20 ft row.

Alternate Every 14 Days:
Mix 1 to 2 cups of Hoss Calcium Nitrate –AND – 1 to 2 cups of Hoss Micro-Boost Micronutrient Supplement per 20 ft. of row.

* To prevent Blossom End Rot: Apply ½ cup of Hoss Pelletized Gypsum Soil Conditioner per plant. Spread evenly around plants rootsat bloom set and every 2 weeks after.

Pro Tip: Avoid excessive nitrogen, which promotes foliage at the expense of fruit.

Irrigation & Watering Schedule

• Needs 1-1.5” water per week

• Keep soil consistently moist (not soggy)

• Mulch heavily to retain moisture and moderate soil temperatures

• Use Drip Irrigation Kits to keep moisture away from the fruit and leaves.

Harvesting & Storage

Harvest:
Peppers can be harvested green or left to ripen to full color for sweeter flavor. Use pruners or scissors to avoid breaking branches. Regular harvesting encourages continued production.

Storage:
Store fresh peppers unwashed in the refrigerator for up to 1–2 weeks.

Preservation Tip:
Peppers freeze well. Chop and freeze raw, or roast and peel before freezing.

Sustainability & Garden Tips

• Rotate crops yearly (avoid planting after tomatoes, potatoes, or eggplant)
• Mulch to retain moisture and suppress weeds
• Stake or cage plants to support heavy fruit loads
• Compost healthy plants at season’s end

FAQs

How long do peppers take to produce?

Typically 60–90 days after transplanting, depending on variety.

Can peppers grow in containers?

Yes. Use at least a 5-gallon pot with good drainage.

Why are my pepper flowers falling off?

Usually caused by heat stress, drought, or excess nitrogen.

What causes blossom end rot on peppers?

Blossom end rot appears as a dark, sunken spot on the bottom of the fruit. It’s caused by inconsistent watering and poor calcium uptake—not a disease. Maintain even soil moisture and avoid letting plants dry out.

Why are my peppers small?

Small fruit is usually caused by stress—high heat, inconsistent watering, overcrowding, or low fertility. Ensure plants receive full sun, steady moisture, and proper spacing.
