Before planting, you need to know the best time to plant turnips and how long it takes them to grow from seed to maturity?
Turnips are cool-weather plants that enjoy the cool weather. Brassica Rapa, as it’s known scientifically, is a staple for both humans and livestock. The swollen turnip root is an enlarged stem that contains very high fiber, vitamins, and cancer-fighting compounds. You can eat it raw, stewed, mashed, boiled, or even mixed with other root crops.
The turnip leaves are high in vitamins, calcium, folate, thiamine, or iron and are cooked and eaten like kale or spinach.
Some farmers grow turnips to feed their livestock. They are also planted in the fall to attract deer in hunting areas.
What Is The Best Time To Plant Turnips?
The best time to plant turnips depends on the variety and growing turnips for roots or tops. Turnips take from 5 weeks to 2 months, from planting a seed to harvesting.
The crisp, round root thrives in cool weather, so you must calculate your days properly to ensure you sow your seeds once the soil warms up in the spring.
The turnip seeds require consistent warm temperatures above 40 degrees F. The warm weather helps them sprout quickly in a week or two. Be sure to wait until your temperatures are constantly at 40 degrees F to sow your seed.
Plant early enough before it gets hot. Too much heat causes roots to become woody and bitter-tasting. Turnips take five weeks to two months from planting a seed to harvest. The crisp, round root stems thrive in cool weather. You must plan when to plant and how to shield them from too much sun to get the best out of them.
If you are experiencing a cool season, continue to plant more seeds every two or three weeks to help you get a good succession harvest. This will help you avoid too many turnips at one time. The mature turnip can tolerate light freeze and actually taste sweeter after frost. However, stop planting at least two months into a hard freeze because it can kill turnips.
With that said, you can plant your seeds in March, April, or May. If there is enough time for a fall harvest, start a new round in early August, September, and October.
This is all dependent on local weather averages, so check your area weather forecast before planting.
There are two secrets to getting sweet turnips and yummy greens. They are:
- Plant turnips at the right time
- Get your seeds sprouted in warm soil and keeping your plants growing actively until harvest time.
This means taking good care of your plants by watering them properly during the dry season, thinning young plants to leave only the strong ones, creating more growing room, etc.
Plant your turnips in full sun in reasonably well-drained soil. Make sure your soil is dug at least 8 inches deep, and add compost for faster root development and growth. Scatter the seeds lightly, rake them into the topsoil, and water them lightly.
Harvest your turnips on time to ensure they are well grown. You can store them for up to two weeks in the fridge. You can pull larger roots out and cut off the tops and store them in a cool, dry place for months to come.

Caring For Your Turnips
Now that you know how to plant turnips, it’s important to look at how to grow turnips in terms of the care they need. Turnips require much care that you ought to give them. This includes:
Watering and Feeding. It is paramount to keep your soil moist and feed it with compost to help your turnips grow fast. Never allow your soil to dry out. When turnips grow slowly, they get woody and strong flavored. Add compost when planting turnips and side-dress them with aged compost at midseason.
Thinning and Weeding. Keep your turnip beds weed-free all the time. Overcrowding may cause your turnips to get stunted growth due to small roots. Thinning helps to remove the weak plants and provides ample space for the growing root. Mulch your turnips with straw to protect the growing tuber tops from sunburn.
Eliminate Pests. Flea beetles and aphids attack turnips, and they are easy to prevent—control aphids infestation by pinching out infested foliage. Weeds bring about flea beetles – keep your turnip garden free of weeds.
Fight off Diseases. Turnips are affected by diseases like white rust fungus that can cause small white cottony blisters on the upper surface of leaves. They also form a yellow discoloration on the undersides. Controlling these diseases before they form is beneficial.
