Why I Grow It

Growing food in the city comes with its own set of challenges, but bok choy handles them all. This plant is built for balcony containers, rooftop pots, or even a sunny windowsill. It stays compact, which makes it the perfect fit for a cramped apartment. You get farm-to-table freshness without needing an actual backyard. There is something incredibly satisfying about picking fresh greens for dinner right outside your window. It is a simple way to eat better and live a bit more sustainably in the middle of NYC.

Growth Essentials

Light

Bok Choy prefers 4-6 hours of direct sunlight. Partial shade tolerated. Indoors: Grow in pots with bright light or hydroponically using grow lights for 10-12 hours.

Water

Keep the soil damp. Bok choy thrives with regular watering, so aim for a consistent moisture level. Indoor plants need a quick daily check to ensure the soil isn't drying out. For those outdoor balcony or rooftop pots, water even more often during a heatwave. A bit of mulch goes a long way in holding that moisture where it belongs.

Temperature

Bok Choy is a cool weather crop and enjoys 55-75°F, ideally 60-70°F. Plant outdoors in March-May and August-September in NYC zone 7b. Indoors, maintain 60-70°F year-round.

Containers

Indoors: 8-10" wide, 8" deep, 1 gallon. Outdoors: 8-10" wide, 8-10" deep, 2-3 gallons

Soil

Bok Choy thrives in rich, well-draining soil with organic matter, such as compost from kitchen scraps or well-rotted manure.

Fertilizer

Apply high-nitrogen fertilizer 20-10-10 every 3-4 weeks.

Organic Options: fish emulsion, blood meal. Consistent fertilization supports rapid, leafy growth.

Harvesting Tips

Harvest outer leaves or whole heads of bok choy as needed. Regular harvesting promotes continuous production.

Harvest Time

Quick: 5-6 Weeks

Common Growing Issues

Why is my Bok Choy wilting?

Why It's Happening:

Bok Choy has a lot of water in its stems. The heat reflecting off NYC brick walls can dry the plant out in just a few hours.

How to Fix It:

Water your plant in the early morning so it stays hydrated. If it is a very hot day, move your pot into a shady spot to keep it cool.

Why is my plant growing a tall stalk?

Why It's Happening:

This is called bolting. NYC buildings trap heat, which makes the plant think summer has arrived too early.

How to Fix It:

Plant Bok Choy in the spring or fall when it is cool. If a heat wave hits the city, use a sunshade to block the hot afternoon sun.

Why are the leaves turning yellow?

Why It's Happening:

This usually means the soil is too wet. NYC humidity makes it hard for water to dry out of small pots.

How to Fix It:

Make sure your pot has holes in the bottom. Only water when the top of the soil feels dry. Adding worm castings helps the soil stay healthy and airy.

What are these tiny bugs on the leaves?

Why It's Happening:

Aphids love the sweet, crunchy leaves of Bok Choy. They spread quickly in crowded city gardens and balconies.

How to Fix It:

You can buy ladybugs to release on your plant to eat the aphids. You can also wash the bugs off with a gentle spray of water in your sink.

Why is there gray fuzz on the leaves?

Why It's Happening:

This is Downy Mildew. It happens because city air stays wet and does not move well between tall buildings.

How to Fix It:

Space your plants out so air can move through the leaves. Pour water on the soil, not the leaves. Use beneficial nematodes to keep the roots strong.
