Popular European staple food and an easy root vegetable to grow is a turnip. The best thing about it is that it provides many nutrients and benefits [1].

Turnip is a cruciferous vegetable with a creamy white color and a purple top, though it also comes in different colors.

Even though it is a root veggie, it is not related to potatoes. Instead, it is relative to broccoli, Brussels sprouts, arugula, and kale. They belong to the same family as rutabagas.

For those who need more fiber in their diets, turnips provide plenty. So look once again at this vegetable that is often overlooked and learn its benefits, how to grow, harvest, and prepare.

They are great for a high-fiber diet. Fiber helps to reduce pressure and inflammation in the colon. High fiber food can reduce the prevalence of diverticulitis flares.

Turnips absorb water in the colon and therefore make for easier bowel movements. However, it is advisable to talk to a doctor before eating high fiber foods.

They also contain dietary nitrates and can provide many benefits for blood vessel health. Among them, blood pressure reduction, and will inhibit blood platelets from sticking together.

Turnips also provide potassium that can help to lower blood pressure by releasing sodium from the body and helps dilate arteries.

A high intake of cruciferous vegetables like turnip greens are associated with lower cancer risk [3]. They contain several compounds that can protect against certain cancers.

Growing Them

If you’re planting as a summer crop, you want to plant them early. If you’re going to have them all winter through then, you have to plant them in the late summer to be able to harvest them before the first frost.

When preparing your garden, keep in mind that turnips need a full sun location but can tolerate partial shade.

When preparing the bed, rake, and hoe so that the soil is well combined. Then sprinkle the turnip seeds and rake them in gently.

When planting, ensure that the seeds are sunk about ½ an inch deep and 3 to 20 seeds per foot. Once the seeds are planted, water right away.

When they begin growing, thin the seedlings so that they are about 4 inches apart. This will give them lots of room to form healthy roots.

Space your gardening in breadths — planting at ten-day intervals as this will have you harvesting every couple of weeks.

Turnips are a staple food in many cultures around the world, and very common in many backyard vegetable gardens. They are loved for their fleshy roots and leafy greens.

Unfortunately, they also taste great to pesky bugs. Most pests that attack them can be picked off of the plants, but some require somewhat aggressive treatment.

1. Foliage Caterpillars

Caterpillars that feed on foliage enjoy turnip greens. The most common caterpillar pests are cabbage loopers, beet armyworms, imported cabbage worms, and diamondback moth caterpillars.

These can be treated by either spraying the plants with Bacillus thuringiensis or hand-picking them off.

Organic pesticides such as Spinosad and AzaGuard can also help eliminate these pests.

2. Soil-Based Caterpillars

Soil-based caterpillars like cutworms are nocturnal. These feed on the leaves and stems of younger plants.

Even if you don’t see these pests, you’ll notice that seedlings down to soil level and the attack has been among the rows.

If you plow your garden ten days before you start to plant, you can eliminate the eggs and larvae of the pests. Beneficial Nematodes can also kill cutworms and other harmful soil-based caterpillars.

3. Aphids

Turnip, green peach, and cabbage aphids are active feeders on this veggie.

These tiny bugs on plants have soft bodies and they feed with sharp mouthparts. However, they can be tolerated because they don’t harm turnips but will affect the leaves.

For treatment, simply mix a solution of 4-5 teaspoons of organic liquid soap in one-quart water and spray plants.

Ecoworks can also be applied during cloudy conditions and when the temperatures are below 90 degrees F.

4. Whiteflies

Whiteflies are sap-feeding insects that attack many crops. They are tiny and resemble moths in flight.

They produce honeydew, attracting a sooty kind of mold that disrupts turnip photosynthesis.

Treat whitefly infestation with either horticultural oil or insecticidal soap. You can also blast them off your plants with a jet hose.

5. Maggots

Cabbage and seed corn maggots are hard to distinguish. These legless and small larvae burrow into the roots and live beneath the soil.

They enjoy feeding on newly sprouted plants but won’t feed on enlarging roots.

Cabbage maggots will tunnel in and out of the turnips. Afterward, the vegetables are exposed to fungi from the soil.

Scouting for eggs in the soil, as well as releasing nematodes can help get rid of these.


Turnip crops can suffer from root-knot, leaf spot, white rust, scab, clubroot, anthracnose, mosaic virus, and Rhizoctonia rot.

Some of these diseases can lead to crop failure; therefore, rotations and other control measures should be used.

To prevent problems with infections, Brassicas should not be grown on the same spot for more than two years in a row.

If the problem is clubroot, then rotations should be six years.  


Some can be harvested early to get turnip greens. When young and tender, the leaves taste the best.

You can harvest at any size you like; however, the smaller, younger ones are tenderer.

For fall turnips, harvest just after a light frost but before a hard freeze as they’ll have a sweeter taste.
