How Long Do Parsnips Take to Grow?

Parsnips are a type of root vegetable, and they grow in a similar way to carrots. They are cream-colored and generally larger and fatter than carrots.

They have a rosette-like top, and the plant grows a taproot at the base.

When they are mature, the vegetable portion of the plant is about 5 to 10 inches wide.

Parsnips also grow yellow umbel-shaped flowers. In terms of how long you need to wait, here’s what I found out:

Parsnips have a long growing season. On average, it takes Parsnips 120 to 180 days to grow from seed to harvest. After the seed matures, the plant may die, so proper care must be taken to preserve mature Parsnips after harvest.


Growing parsnips in full sun

Parsnips are best grown in full sun, though they will tolerate partial shade.

The soil must be well-drained and rich in organic matter.

Parsnips also require regular moisture and a slightly acidic pH. Ensure that parsnips get at least one inch of water per week.

Watering them too frequently may cause weak roots, so water slowly.

Parsnips are best grown in well-drained, loose soil. The soil should not be compacted, and it should be aerated. Parsnips do not like soil that is too hard or too wet.

They also prefer soil that is 6.0 to 7.0 degrees Fahrenheit.

Parsnip seeds should be planted in the soil in early spring. It is a good idea to soak them overnight before planting. Parsnip seeds will germinate in three weeks, and they should be thinned at 6 weeks.

Parsnips are a winter root vegetable. Their full flavor comes when the temperatures are near freezing. They can also tolerate partial shade.

Before planting, add aged compost or manure to the soil. The soil pH should be at least 6.0 and should be free of rocks and lumps. Parsnips are best grown in soil that has been dug to a depth of 12 inches (30 cm).

Growing parsnips in partial shade

Growing parsnips in the partial shade can be a challenge. Parsnips are best grown in full sun, but they will tolerate partial shade.

Parsnips need a minimum of four hours of sunlight a day. Planting your parsnip seeds in the full shade can lead to poor crop yields.

Parsnips prefer a soil pH of 6 to 7. A long growing season with moderate temperatures is ideal. Parsnips can survive freezing temperatures.

To get a healthy crop, prepare the soil by adding aged compost two or three months before planting. Also, till the soil to a depth of 12 inches (30 cm) before planting.

Parsnips do well in soil that drains well. Parsnips grow best in soil that is not too rich or too dry.

You should plant the seeds in soil that is well-drained and contains plenty of organic matter.

Add well-sifted compost to the soil and mix in a small amount of sand. After the seeds have been planted, cover them with half an inch of soil.

If the soil is too clay-like, it’s important to work the compost into the soil or the plants will struggle to grow roots.

Proper soil conditions for Parsnips

Parsnips are best grown in full sun in well-drained soil with a pH level of 6.0 or higher. Parsnips are fast-growing and should be sown about 1/2 inch deep, with a spacing of 1 inch between each seed. Parsnips can also be grown in rows.

Often, radishes can be planted in between the rows to provide a row marker. Parsnips can be left in the garden after light frosts and can be overwintered under heavy mulch.

Parsnips need average temperatures between 45 and 70 degrees Fahrenheit.

The first few weeks of growing are cool, and they can tolerate cold temperatures at the beginning and end of their growing season.

They should also have plenty of light, and the soil should be free of weeds. Parsnips also need low air humidity.

Aside from that, parsnips need nearly a full season to mature, so it’s important to grow them during the right seasons.

If you’re interested in growing parsnips, you’ll want to plant the seeds in the spring, so you’ll get a crop in time for the winter.

The Best Time to Plant Parsnips

The best time to plant parsnips is during the fall. These root crops require between two and four weeks to germinate.

Parsnips prefer moist but loose soil and do not mind nutrient-depleted soil. However, they do not do well in hot, dry conditions.

Parsnips grow best in temperatures of 45 to 70 degrees Fahrenheit. However, they can tolerate freezing temperatures at the start and end of the growing season. Parsnips also grow well in low air humidity.

They are pollinated by wind and insects. If you’re looking for an early-season variety, you can try the Harris Model cultivar, which produces large roots with a mild honey flavor.

Parsnips can grow to quite a depth, so you’ll need to prepare your planting area before sowing the seed.

Loosen the soil to about a foot depth, depending on the variety. Then, prepare the planting bed by removing any rocks or twigs.

This will help keep the soil moist and prevent weeds from competing with the roots.

Parsnips are ready to harvest when they have reached about 3/4 inches in diameter.

If you dig them up too early, you risk wasting them.

Moreover, exposure to frost makes the roots sweeter. You can also store them in cool, moist boxes or peat for 4 to 6 months.


Parsnips do well in well-drained, sandy soil with a pH of 6 to 8.

They do well in soil with some aeration, so make sure you add organic matter to the soil before planting. Parsnip seeds will not germinate if they dry out after planting.

Parsnips will also not germinate well if the soil is too rich, so be sure to mix in some compost with the sand before planting them.

You can then cover them with about 1/2 inch of soil. Alternatively, if your soil is too hard, you can cover the seeds with a floating row cover, which will shade the soil and conserve moisture.
