Why I Grow It

I grow chili peppers because they are incredibly forgiving. As a busy NewYork, peppers don't quit on me if I miss a day of watering. I love that they produce a massive harvest in small containers, giving me the most value for my limited space. I turn my extra peppers into homemade hot sauces, dry them into flakes, or ferment them for a flavor boost. Beyond the kitchen, these plants attract helpful bees to my garden and they brighten up the space. Shishitos for dinner, yes chef.

Growth Essentials

Light

Chili peppers require 6-8 hours of direct sunlight daily. Indoors: Grow in large pots with bright light or hydroponically using grow lights for 12-14 hours.

Water

Keep soil consistently moist but not soggy. Indoors, air can dry soil quickly; outdoors, water regularly, and mulch helps retain moisture.

Temperature

Chili peppers are a warm weather crop and thrive in 70-85°F, ideally 75-80°F. Plant outdoors in May-June in NYC zone 7b. Warm temperatures help fruit development.

Containers

Indoors: 10-12" wide, 10" deep, 3 gallons.

Outdoors: 10-12" wide, 12" deep, 3-5 gallons

Soil

Chili peppers love well-draining, nutrient-rich potting mix with compost from vegetable peelings or garden compost.

Fertilizer

Use balanced 10-10-10 early and high-phosphorus 5-10-10 during flowering. Organic options: compost, fish emulsion, bone meal. Fertilize every 2-3 weeks for optimal growth.

Harvesting Tips

Remove early flower buds and leggy growth to promote bushier plants. Regular trimming focuses energy on producing healthy, abundant peppers.

Harvest Time

Long: 16-20 Weeks

Common Growing Issues

Why is my pepper plant wilting?

Why It's Happening:

High-floor winds and heat from NYC buildings dry out pots very fast. If the soil is wet and it's wilting, the roots might be rotting.

How to Fix It:

Check the soil. If it is dry, give it a deep soak. If it is wet, let it dry out. Adding compost helps the soil hold just the right amount of water.

What are these tiny bugs on the new leaves?

Why It's Happening:

Aphids love the warm, sheltered spots on NYC balconies. They are the most common pest for city peppers.

How to Fix It:

Buy ladybugs to release on your plants to eat the aphids! You can also wash them off with a strong spray of water or use a mix of water and mild soap.

Why are the leaves turning yellow?

Why It's Happening:

This is usually from too much water or not enough food. NYC humidity can keep pots soggy for too long.

How to Fix It:

Make sure your pot has holes. Give the plant a balanced 10-10-10 food. Mixing in worm castings provides steady energy to keep leaves green.

Why is my plant growing so slowly?

Why It's Happening:

Peppers need a lot of sun and heat. If tall buildings block the sun for most of the day, the plant will stall.

How to Fix It:

Move your pot to the sunniest spot you have. Use a 5-10-10 plant food to help the plant focus on growing peppers instead of just leaves.

Why is there white powder on the leaves?

Why It's Happening:

This is Powdery Mildew. It happens because city air is sticky and does not move well between tall buildings.

How to Fix It:

Do not crowd your plants. Cut off the sick leaves. You can use beneficial nematodes in the soil to keep the root system strong and healthy.
