Parsnips are healthy winter vegetables, closely related to parsley and carrots, with cream-colored roots that work perfectly in roasts, soups, stews, and even fries! Though they’re nutritious and flavorful, parsnips aren’t the easiest vegetables to grow. They’re slow to germinate and are a bit particular about their growing conditions. If they don’t find the right environment to grow in, you’ll find deformities in the roots, like forking.
Why do parsnips fork? Is there any way you can prevent it and harvest the perfect roots each time? Continue reading, and you’ll find out everything there is to know.
What Is Forking On Parsnips?
Forking on parsnips is when the parts above the ground appear perfectly normal, but the roots are deformed and forked. Other than the extensive branching, the roots are well developed and firm.
Are Forked Parsnips Edible?
Forking in parsnips is merely an external flaw. Other than the unappealing shape of the roots, you won’t find anything wrong with the flavor, texture, or nutritional value. If you’re growing them to sell to the farmer’s market, deformities like forking will significantly diminish their market value.
However, if you’re simply growing them for use in your own kitchen, forking isn’t that big of a problem. Though they make amusing pictures and are difficult to peel, they’re as good for cooking as the perfect, straight parsnips you find in vegetable sections of the grocery store.
In short, your mutant parsnips are just as nutritious and flavorsome as the straight, slender ones. And since they’re not participating in a beauty pageant, toss them in stews, soups, and roasts, and you won’t even realize they were deformed to start with.
Why Do Parsnips Fork?
Though they’re absolutely edible, you still wouldn’t want to miss the happiness in pulling out perfect roots at harvest time. The key to perfect harvests is to find out what caused the problem in the first place so you can rectify it in the next growing season.
Here are some reasons why your parsnips might be forked:
Unsuitable Soil Structure
Parsnips, like most root vegetables, like to grow in light, friable soil. Loamy or sandy soil, rich in organic material, is perfect to start your parsnips with. If you’re getting forked parsnips, one of the most common reasons is heavy, compacted soil or a rocky one. With heavy soil or rocks obstructing their development, roots find it challenging to grow straight down into the soil and turn out short and branched.
Prevent distorted roots by tilling and sifting the garden bed to about 12 inches, removing any stones, sticks, or large solid structures that you find along the way. If you have heavy clay soil, amend it with aged-compost and sand to improve soil structure to promote straight parsnips. If you don’t have the best soil in your garden, another solution is to grow your veggies in a raised bed prepared with packed soil and sand.
Too Much Nitrogen
It might be hard to believe, but incorrect fertilization can also result in forked parsnips. The use of high-nitrogen fertilizers, especially right after you’ve sown the parsnip seeds, can also result in the deformities that are bothering you. Parsnips don’t need as much nitrogen as most of your other garden plants.
For organic fertilization of your parsnip crop, select well-aged manure. Fresh manure has a higher content of nitrogen, which can result in forking and branching of roots. If you’re incorporating synthetic fertilizers, choose a low-nitrogen feed, for example, 5-10-10 fertilizer.
Transplanting parsnips can also be one of the causes of deformities. Transplanting root vegetables, especially those with long taproots, is never a good idea. That’s because root vegetables are very sensitive to such disturbances.
Avoid transplanting parsnips. Sow the seeds directly in the garden or container as soon as the soil temperatures are higher than 50°F. Leave them growing in the same spot until they’re ready for harvest to avoid disturbing the roots.
Oddly shaped roots can also result from the inadequate spacing between the plants. Tight plantings can result in twisted and forked parsnips instead of the straight ones you’re looking for.
Once the seedlings develop their first true set of leaves, thin them to 3 to 4 inches apart. This will allow plenty of space for each root to develop freely, without being obstructed by its neighbors.
Weeds in your garden bed is another common reason for deformed roots. Since weeds have their own underground root system that competes for nutrients against your crop, it’s not surprising to find forked parsnips in a weedy garden.
Keep your garden weed-free throughout the growing season, so the unwanted roots don’t disturb the development of your parsnips.
Root-knot nematodes can also result in knotty, forked parsnip roots. They are microscopic worms that feed on the plants, leaving galls on the roots. These galls or knots prevent the plant from accessing water and nutrients to its fullest capacity, stunting the growth.
Select root-knot nematode-resistant parsnip seeds to prevent the problem right from the start. With certified nematode-free parsnip seeds, you can be sure you won’t find this disease in your crop. Also, since root-knot nematodes are less active during the winters, overwintering parsnips is also a good idea to prevent the damage done by these pests.
Can You Grow Parsnips In Clay Soil?
Yes you can grow parsnips in clay soil. You can use the clay to your advantage. Here are the steps to follow:
- Use a metal pole or broomstick
- Push the pole into the soil to a depth of 1 foot.
- Wiggle the pole round and round
- You want to make a cone shaped V in the ground up to 6″ wide
- Fill the hole with compost
- Put two parsnip seeds on top
- After the seeds have germinated remove the weakest
