Growing Conditions for Bok Choy Plant

Which growing conditions will give you a bountiful harvest? The bok choy is a delicate vegetable that relies on specific needs for it to produce healthy plants. What are these conditions?

  • Bok choy is a cold climate plant. They are more comfortable in cold climates. Hot weather will cause them to bolt (produce seeds too quickly). Even frigid weather of below 50°F will cause the vegetable to bolt when it is young.
  • It needs full sun. The bok choy veggie needs full sun to grow properly. It can, however, grow under partial shade when in a warmer region.
  • Bok choy needs soil rich in nitrogen, phosphorus, and potassium. As a heavy feeder, the ground needs to be replenished from time to time, so it doesn’t run out of necessary nutrients.
  • Bok choy needs well-drained soil.
  • Bok choy grows better in the spacing of 9 per square for baby plants and 4 per yard when you’re looking to harvest full heads. When planting in rows, a spacing of 24 inches between rows and 8 inches apart is ideal.

When to Plant Bok Choy?

The best time to plant the bok choy vegetable is during spring, very close to the predicted last frost date of your area. This is because the plant can bolt easily in the summer and during frost season for young plants. It grows well in autumn and spring. When it comes to growing bok choy indoors, most of these restrictions do not hold. You can plant almost anytime as long as you can manage the weather conditions. If you’re sowing indoors for transplanting then, you should sow two weeks before the predicted last frost date.

How Long to Grow?

It takes about 30 days to grow into a baby bok choy and between 45 to 55 days to grow into a mature plant depending on the variety.

How to Grow Bok Choy? (Growing Tips)

You’re done preparing; it now time to do the actual planting.

For Outdoor Planting

Sow the seed ½ an inch into the ground in autumn or early spring to avoid the hot summer months. Water lightly but frequently as it needs enough water to germinate. Sow them 2 inches apart and thin them once they start sprouting in 8day’s time.

You can also decide to plant baby bok choy directly to the soil instead of planting seeds. Buy them from your garden stores and plant in your garden after the last frost date. Do you know you can make use of raised garden beds filled with soil to grow your bok choy? Well, now, you do.

For Indoors Planting

Because of its delicate weather conditions, a lot of people prefer first to grow the bok choy indoors and allow it to grow leaves before transplanting. To grow this plant indoors, you need a tray with individual cells or blocks to avoid transplant shock.

How to Plant and Grow Bok Choy

How to Take Care of Bok Choy

How to Take Care of Bok Choy

Here are a few things you should do to protect your plant and give it a conducive environment to grow.

  • Weed regularly: You do not want your garden to be overrun with weeds, do you? By weeding immediately you spot the growth of weeds, you’re keeping your garden clear and also giving your plant space and nutrients it needs.
  • Water generously: The stalk of the bok choy plant is filled with water, and for it to produce this sweet vegetable instead of bitter plants, it needs enough water. Enough, not too much as standing water or soggy ground can cause root rot.
  • Thin the plants: If you planted the seeds directly to the ground, then you most likely planted them closer than they’re comfortable. Immediately they start sprouting and producing leaves; use scissors to thin some weak plants to provide more space for the others to grow into full heads.
  • Apply fertilizer: NPK fertilizers are essential for the growth of this fast-growing veggie. You may decide to make use of compost if you’re practicing organic farming.


Harvesting Bok choy

Now to the part you’ve been waiting for – harvesting. After planting and caring for your bok choy plant, it’ll be ready for harvesting in 50 days, depending on species.

You can even start enjoying this fast-growing plant before the head fully matures by cutting out the grown outer leaves. Make sure you do not cut out more than 1/3 of the plant.

At maturity, use a pair of scissors to cut the head in one snip. Put your scissors at the base, just above the ground. Do this when the weather is cool to prevent it from wilting quickly.

Take the head out of the sun and into the shade immediately you cut it as the leaves can shrink quickly when left under the sun. Store in a cool, dry place
