When to Start Taiwanese Bok Choy

The best time to start growing Taiwanese bok choy is in the early spring or late summer. The mild temperatures of these seasons are ideal for the plant’s growth. Avoid planting during the extreme heat of summer or the freezing temperatures of winter.

Early spring provides the perfect conditions for Taiwanese bok choy to establish its roots and thrive. As the weather warms up but before the scorching heat sets in, the plant can take advantage of the moderate temperatures to grow vigorously. In late summer, the cooler temperatures offer a respite from the heat, allowing the bok choy to flourish without the stress of high temperatures.

It’s important to consider the specific climate of your region when deciding when to start growing Taiwanese bok choy. In areas with milder winters, planting in late summer can lead to a bountiful harvest well into the fall months. Conversely, regions with harsh winters may benefit more from starting the bok choy in early spring to ensure a healthy growth cycle before the cold weather sets in.

How to Grow Taiwanese Bok Choy From Seed

To grow Taiwanese bok choy from seed, follow these simple steps:

Choose a sunny spot in your garden that receives at least 6 hours of direct sunlight each day.
Prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller. The soil should be well-draining and rich in organic matter.
Sow the seeds directly into the soil, spacing them about 6 inches apart. Plant the seeds about ¼ inch deep and cover them lightly with soil.
Water the seeds gently but thoroughly to ensure the soil is evenly moist. Avoid over-watering, as this can lead to root rot.
Keep the soil consistently moist during the germination period, which usually takes about 7-14 days.
Once the seedlings have emerged, thin them out so that they are spaced about 8-12 inches apart. This will allow each plant to have enough room to grow.

How and When to Transplant Taiwanese Bok Choy

If you prefer to start your Taiwanese bok choy indoors or in a greenhouse, you can transplant the seedlings into your garden once they are about 3-4 inches tall. Transplanting should be done when the weather is mild, and there is no risk of frost. Follow these steps:

Choose a sunny spot in your garden with well-draining, fertile soil.
Prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller. Amend the soil with compost or well-rotted manure to improve its fertility.
Dig a hole slightly larger than the size of the root ball of the seedling. Gently remove the seedling from its container, being careful not to damage the delicate roots.
Place the seedling in the hole, making sure the top of the root ball is level with the soil surface. Firmly press the soil around the base of the seedling to secure it in place.
Water the transplanted seedlings thoroughly to settle the soil around the roots. Avoid wetting the foliage to prevent the risk of disease.

How to Plant Taiwanese Bok Choy – Spacing and Patterns

When planting Taiwanese bok choy in your garden, proper spacing is important to ensure optimal growth and prevent overcrowding. Follow these guidelines for spacing:

Space the plants 8-12 inches apart in rows that are 12-18 inches apart.
Alternatively, you can plant Taiwanese bok choy in raised beds or containers. In this case, space the plants 6-8 inches apart in all directions.
For a continuous harvest, make successive plantings every few weeks.

How Long to Grow Taiwanese Bok Choy

Taiwanese bok choy is a fast-growing vegetable that can be harvested in as little as 30-40 days after planting. However, the exact time to maturity may vary depending on the variety and growing conditions. Keep an eye on your plants and harvest them when the leaves are crisp, tender, and the desired size.

How to Water Taiwanese Bok Choy

Proper watering is essential for the healthy growth of Taiwanese bok choy. Follow these tips to ensure your plants receive the right amount of water:

Water the plants deeply and thoroughly, providing about 1 inch of water per week.
Avoid overhead watering to prevent the development of fungal diseases.
Water the plants in the morning or early evening to reduce evaporation and allow the foliage to dry before nightfall.
Monitor the soil moisture and adjust your watering schedule as needed, taking into account the weather conditions and rainfall.

How to Fertilize Taiwanese Bok Choy

While Taiwanese bok choy is a relatively low-maintenance plant, it can benefit from regular fertilization to promote healthy growth and abundant yields. Here are some tips for fertilizing your plants:

Before planting, amend the soil with compost or well-rotted manure to improve its fertility and organic matter content.
Apply a balanced organic fertilizer once a month, following the manufacturer’s instructions for application rates.
Avoid over-fertilizing, as this can lead to leafy growth at the expense of the development of firm, compact heads.

Sunlight Requirements for Taiwanese Bok Choy

Taiwanese bok choy thrives in full sun but can tolerate partial shade. However, it is important to provide your plants with at least 6 hours of direct sunlight each day to ensure proper growth and development. If you are gardening in a hot climate, consider providing some afternoon shade to protect your plants from scorching.

Soil Requirements for Taiwanese Bok Choy

Taiwanese bok choy prefers well-draining soil that is rich in organic matter. Here are some guidelines for preparing the soil:

Test your soil pH and aim for a slightly acidic to neutral range of 6.0-7.0 for optimal nutrient uptake.
Loosen the soil to a depth of at least 8 inches, removing any rocks, roots, or debris.
Incorporate organic matter such as compost, well-rotted manure, or leaf mold to improve the soil structure and fertility.

How to Grow Taiwanese Bok Choy Outdoors

Growing Taiwanese bok choy outdoors is a straightforward process that yields delicious results. Follow these steps to ensure a successful harvest:

Choose a sunny spot in your garden that receives at least 6 hours of direct sunlight each day.

Taiwanese Bok Choy Companion Plants – What to Plant With & Not Plant With Taiwanese Bok Choy

Companion planting is an effective way to maximize space, deter pests, and enhance the health of your Taiwanese bok choy plants. Here are some companion plants that pair well with Taiwanese bok choy:

Lettuce: Plant lettuce in between your bok choy plants to maximize space and provide some shade for the bok choy during hot weather.
Radishes: Radishes repel aphids, which are common pests of bok choy. Plant radishes as a border around your bok choy to deter aphids.
Carrots: Carrots and bok choy have similar growth habits and growing requirements, making them compatible companions.

On the other hand, there are some plants that can potentially hinder the growth of Taiwanese bok choy. Avoid planting bok choy near:

Mustard greens: Mustard greens belong to the same family as bok choy and can be prone to similar pests and diseases.
Cabbage: Cabbage and bok choy are both brassicas and may compete for nutrients and space.
Onions: Onions have a pungent odor that may attract onion maggots, which can cause damage to bok choy.

Common Taiwanese Bok Choy Pests and Diseases

Taiwanese bok choy is generally a healthy and robust plant, but it can be susceptible to a few pests and diseases. Here are some common issues to watch out for:

Aphids: These small, soft-bodied insects can quickly infest bok choy plants, causing distortion and stunted growth. Monitor your plants regularly and use insecticidal soap or a strong jet of water to control aphid populations.
Cabbage worms: The larvae of the cabbage white butterfly can cause severe damage to bok choy foliage. Handpick the worms from the plants or use organic insecticides containing Bacillus thuringiensis (Bt) to control them.
Clubroot: Clubroot is a soil-borne disease that affects brassicas, including bok choy. It causes stunted growth, yellowing leaves, and swollen, malformed roots. Rotate your crops, practice good sanitation, and choose resistant varieties to prevent clubroot.
