What is Companion Planting?

Companion planting is the practice of growing different plants together to benefit each other. Certain plants can attract beneficial insects, repel pests, or provide shade and support for others. It's a natural way to promote healthy plant growth and maximize yields without using chemicals or pesticides.

Pak choi is a member of the brassica family, which includes other vegetables like broccoli, cauliflower, and cabbage. These plants are susceptible to similar pests and diseases, so by planting them together, you can create a barrier against common issues. Additionally, pak choi is a heavy feeder and can deplete soil nutrients quickly, so planting it with nitrogen-fixing legumes like beans or peas can help replenish the soil.

Companion Plants for Pak Choi

There are several plants that pair well with pak choi, here are a few examples:

  • Garlic: Garlic has natural anti-fungal and anti-bacterial properties that can protect pak choi from common diseases.
  • Nasturtiums: Nasturtiums attract beneficial insects like aphids and caterpillars that can prey on pests that attack pak choi.
  • Lettuce: Lettuce provides shade for pak choi and can help regulate soil temperature during hot weather.

Tips for Companion Planting Pak Choi

Plant at the Right Time

Pak choi is a cool-season crop that prefers temperatures between 50-70°F. It's best to plant in early spring or late summer/early fall, depending on your location. If you're planting with other vegetables, make sure they have similar temperature requirements.

Leave Enough Space

Pak choi needs room to grow, so make sure to space plants at least 6 inches apart. This will allow for proper air circulation and reduce the risk of disease.

Rotate Crops

To prevent soil-borne diseases, it's essential to rotate crops every year. Don't plant brassicas in the same spot two years in a row, and try to wait at least 3-4 years before planting them in the same area again.

Use Mulch

Mulching around plants can help retain moisture and suppress weeds. Organic mulches like straw or leaves can also help improve soil health as they break down.
