Once the seeds have germinated, you can then transfer the seedlings outside and throw those that did not germinate. Germination of parsnip seeds can take as long as 20 days or three weeks. To help the seeds germinate, you can roll the soil lightly or trample it gently after sowing.You can also opt to soak the seeds overnight before sowing.owever, hardy as parsnips are, they have a notoriously long germination period.

Some gardeners opt to âpre-germinateâ seeds by spreading them on a damp towel placed on a seed tray.
They require consistently moist soil and sometimes two weeks or more for germination. Dry or windy weather can mean slow or no germination for carrots. Carrots, parsnips, and parsley take 14 to 21 days to germinate; that means you must keep the seed bed evenly moist for up to three weeks or longer.he sprouts will grow uniform in height and produce a crop two weeks earlier than if you had sown seed directly in the planting bed. Most carrot varieties take 70 to 80 days from sowing to harvest. The best time to grow carrots is in the cool times of the yearâspring or fall.
