Here are a few simple steps by which you can grow green chillies in grow bags at home:

Start with a grow bag with a minimum capacity of about 20 liters for one chilli plant, or you can plant up to three smaller plants per bag. Make sure it has good drainage holes to prevent waterlogging.

For varieties, choose compact types that grow well in containers like Numex Twilight, Jalapeño, or Thai Green. If you love eating spicy and hot things, try Bhut Jolokia or Red Chili. Beginners should start with Green Chilli or Jalapeño since they’re easy to grow and provide steady harvests.

Chillies love light, well-draining soil that stays moist but not soggy. Mix 50% garden soil, 30% compost or cocopeat, and 20% vermiculite or perlite for better water retention and aeration. Add crushed eggshells for calcium and phosphorus, which help fruit growth and protect against pests.

You can also mix in well-rotted cow manure or kitchen waste compost for extra nutrients. Fill the grow bag about 3–4 inches from the top to allow space for watering.

Chilli plants need 6–8 hours of direct sunlight every day, so place your grow bag on a sunny terrace, balcony, or near a south-facing window. Morning sun is best to avoid scorching. Water when the top inch of soil feels dry, usually every 1–2 days depending on the weather.
Keep the soil evenly moist, but never soggy, because too much water can hurt the roots. A light feed with compost or a balanced fertilizer can help the plant grow well and produce more chillies. Also, check for pests like aphids or whiteflies, and remove damaged leaves to keep the plant healthy.

Make sure you do not forget to add the right amount of compost or fertiliser to your plant.

You can use liquid kitchen waste fertilizer or tomato feed high in potassium. Refeed compost every 15 days by gently mixing it into the topsoil without disturbing roots. Once flowers appear, switch to a high-potash fertilizer to encourage more fruits.

Pinch off the bottom leaves and lower branches near the ground, keeping only the upper two branches for bushier growth. Some tall varieties may need a small bamboo stake or trellis for support. Harvest chillies when they reach the desired size and color by snipping them with scissors, not pulling. The more you harvest, the more the plant will produce.
