Bolting of Turnips Plants: Understanding Causes, Prevention and Treatment

Turnips are popular vegetables grown for their nutritious roots and leaves. However, as with any plant, they can be prone to various problems that may affect their growth and yield. One of the most common issues that turnip growers face is bolting. In this article, we will discuss what bolting is, its causes, prevention measures, and treatment options.

What is Bolting?

Bolting refers to the premature flowering and seed production of a plant. This usually occurs when the plant is exposed to stress or unfavorable growing conditions such as high temperatures, extended daylight hours, and inadequate moisture. When a turnip plant bolts, it diverts energy from root development and leaf growth towards flower and seed production, resulting in stunted and bitter-tasting roots and leaves.

Causes of Bolting in Turnips Plants

Several factors contribute to the bolting of turnip plants. Here are some of the common ones:

High Temperatures

Turnips prefer cool weather and cannot tolerate extreme heat. When temperatures rise above 75°F, turnip plants may start to bolt. This is why it is best to plant turnips in early spring or late summer when temperatures are mild.

Extended Daylight Hours

Turnips are short-day plants, meaning they require less than 12 hours of daylight to grow. When exposed to long daylight hours during the summer months, turnip plants may mistake it for springtime and initiate the blooming process.

Inadequate Moisture

Turnips require consistent and adequate moisture to grow healthy roots and leaves. When soil moisture is insufficient, turnip plants may start to bolt in an attempt to conserve water.

Preventing Bolting in Turnips Plants

The best way to prevent bolting in turnips is to provide them with optimal growing conditions. Here are some tips:

Plant at the Right Time

As mentioned earlier, turnips prefer cool weather and short daylight hours. Planting them in early spring or late summer when temperatures are around 60°F - 65°F can help prevent bolting.

Provide Adequate Moisture

Make sure to water your turnip plants regularly to keep the soil moist but not waterlogged. Mulching around the base of the plants can also help conserve soil moisture.

Use Shade Cloth

If you live in a hot climate, consider using shade cloth to protect your turnip plants from direct sun exposure. This can help keep the soil and air temperature cooler and prevent bolting.

Treating Bolting in Turnips Plants

If your turnip plants have already started to bolt, there is still hope. Here are some things you can do:

Remove the Flower Stalks

Once the flower stalks appear, remove them immediately to prevent further seed production. This will redirect the plant's energy back to root and leaf growth.

Harvest Early

If your turnip roots have become stunted and bitter due to bolting, consider harvesting them early while they are still tender and flavorful. You can also harvest the leaves for salads and stir-fries.

Replant

If all else fails, you can replant new turnip seeds in late summer or early fall for another chance at a successful crop.
