Growing parsnips without digging, also known as the “no-dig” method, is an excellent way to produce this delicious root vegetable while minimizing soil disturbance and maintaining soil health. Here’s a step-by-step guide on how to grow parsnips using the no-dig approach:
1. Choose a Suitable Location: Select a sunny spot in your garden with well-drained soil. Parsnips prefer loose, stone-free soil, so choose a location where the soil is friable and easy to work with.
2. Prepare the Bed: Instead of digging, create a no-dig bed by layering organic matter on the ground. Start by marking the area where you want to grow parsnips. Lay down several layers of materials such as cardboard, newspaper, or weed fabric to suppress weeds and grass underneath. This will create a weed-free zone for your parsnips to grow.
3. Apply Compost: Spread a generous layer of well-rotted compost over the cardboard or weed fabric. The compost will enrich the soil with nutrients, making it an ideal growing medium for parsnips.
4. Planting: Sow parsnip seeds directly into the compost layer. Plant the seeds in rows or blocks, spacing them 2-3 inches apart. Sow the seeds to a depth of about 1/2 inch. Cover the seeds with a thin layer of compost.
5. Mulch: Apply a layer of organic mulch, such as straw, leaves, or grass clippings, to conserve soil moisture and regulate temperature. Mulch helps to keep the soil consistently moist and cool, which is ideal for parsnip germination and growth.
6. Watering: Keep the soil consistently moist but not waterlogged. Water the parsnips as needed, especially during dry spells. Deep, infrequent watering is generally better than frequent, shallow watering.
7. Thinning: Once the parsnip seedlings are a few inches tall, thin them to achieve the desired spacing, which is typically 3-4 inches between plants. This allows the remaining parsnips ample room to develop their roots.
8. Maintenance: Unlike traditional gardening, the no-dig method requires minimal maintenance. Pull any weeds that manage to grow through the mulch and monitor for pests. Additional compost or organic matter can be added as a top dressing during the growing season if needed.
9. Harvesting: Parsnips are typically ready for harvest when their roots have reached a suitable size, usually about 2-3 inches in diameter. The flavor of parsnips improves after exposure to a few frosts, making them a great fall and winter crop. Gently loosen the soil around the parsnip and pull it from the ground. Be careful not to damage the roots during harvest.
10. Storage: Store harvested parsnips in a cool, dark, and humid place. They can be left in the ground and harvested as needed throughout the winter, or you can store them in a root cellar or a cool basement.
The no-dig method for growing parsnips not only reduces the effort and labor required but also helps maintain soil structure and health. By using organic matter and mulch to create a nutrient-rich and weed-free environment for your parsnips, you can enjoy a bountiful harvest of these flavorful root vegetables.
Just from my own observations, and working with different soils over the years, I think forking is less to do with nutrients, and stones, although can be the latter depending more on soil type, but is actually more a water issue. After all, I grow my Parsnips next to my Beans every year without issue, and my carrots wherever I have space, in well maintained beds. It’s often said to not water roots so much, because you want them to go down and search for water. However, people generally don’t water enough to start with, especially when using raised beds and compost. This allows mediums to become hydrophobic. It may look wet on the surface, but underneath will remain completely dry, so if your area is not close to the water table to start with, the roots have nothing to search for. This is what creates large side roots. They’re searching for surface water. Other plants do it all the time, it’s just assumed that roots don’t, and yet wild versions do exactly this. We’ve just messed about with cultivated food versions to try controlling the tap root, and prevent it. Perhaps, what we’re seeing, when you get an extreme version, is a throw back in genetics to the wilder nature of the plant.
