• Soil: Choose a well-draining, nutrient-rich seed-starting mix.
• Planting Depth: Sow seeds ¼ inch deep and lightly cover with soil.
• Moisture & Temperature: Keep soil consistently moist and maintain temperatures between 70-85°F. A heat mat can help.
• Light Exposure: Provide 12-16 hours of light daily using grow lights or a sunny windowsill.

Step 3: Germination & Seedling Care

• Chilli seeds typically germinate within 7-21 days.
• Keep the soil damp but not waterlogged.
• Once seedlings emerge, ensure they receive sufficient light and warmth to promote strong growth.

How to Transplant Chilli Pepper Plants

Once your seedlings have 2-3 sets of true leaves, they are ready for transplanting.

Step 1: Harden Off the Seedlings

• Gradually expose plants to outdoor conditions for 7-10 days.
• Start with a few hours per day and increase the duration gradually.

Step 2: Transplanting Process

• Soil Preparation: Use well-draining, nutrient-rich soil with compost.
• Spacing: Plant chillies 12-18 inches apart for good airflow.
• Depth: Keep the root ball level with the soil surface.
• Watering: Water thoroughly after transplanting to help roots establish.

Watering & Feeding

• Water deeply but allow the topsoil to dry between waterings. Overwatering can lead to root rot.
• Feed plants with a balanced fertilizer every 2-3 weeks.
• Once flowering starts, switch to a potassium-rich fertilizer for better fruiting.

Pruning & Staking

• Pinch off early flowers to strengthen root development.
• Stake taller varieties to prevent them from bending under the weight of fruits.

Pest & Disease Management

• Watch for aphids, spider mites, and whiteflies. Use neem oil or insecticidal soap if needed.
• Avoid overhead watering to prevent fungal diseases.

When to Harvest Chillies

Harvesting at the right time affects the flavor and heat of your chillies.

• Color Change: Most varieties change from green to red, orange, or yellow when fully ripe.
• Texture: Chillies should feel firm and glossy when ready.
• Taste Testing: Pick early for a milder flavor or allow full ripeness for maximum heat.

Harvest Method: Use sharp scissors to cut chillies, leaving a small portion of the stem attached.

How Do You Store Chillies?

Proper storage extends the shelf life of your chillies.

Short-Term Storage

• Refrigeration: Store fresh chillies in a paper bag in the crisper drawer for up to 2 weeks.

Long-Term Storage

• Drying: Hang chillies in a warm, dry area or use a dehydrator.
• Freezing: Chop chillies and freeze them in airtight bags for up to 6 months.
• Pickling: Preserve chillies in vinegar and spices for a longer shelf life.

Frequently Asked Questions

How long do chilli pepper seeds take to germinate?

Chilli seeds germinate in 7-21 days, depending on temperature and moisture levels.

Can you grow chillies indoors year-round?

Yes! With 12-16 hours of light daily and temperatures between 70-85°F, chilli plants can thrive indoors.

Why are my chilli plants not producing fruit?

Possible reasons include:

• Excess nitrogen fertilizer (promotes leaves, not fruit)
• Lack of pollination (use a small brush to hand-pollinate flowers)
• Insufficient light (chilli plants need full sun)

How do I make my chillies spicier?

• More sunlight increases capsaicin production.
• Slightly reduce watering before harvest.
• Stress the plant (mildly) by reducing nutrients but not harming it.

Can you save seeds from store-bought chillies?

Yes, but hybrid chillies may not produce the same results. Use organic, open-pollinated varieties for better consistency.
