Planting

When it comes to planting celeriac, there are a few key factors to keep in mind. First, choose a location in your garden that receives full sun. Celeriac prefers well-drained soil, so make sure to amend your soil with compost or organic matter before planting.

Start by sowing the seeds indoors about 10-12 weeks before the last frost date in your area. Fill a seed tray or small pots with seed-starting mix and lightly press the seeds into the soil. Keep the soil moist but not waterlogged, and place the tray or pots in a warm location or under grow lights.

Once the seedlings have reached a height of about 2 inches, they are ready to be transplanted into the garden. Harden off the seedlings by gradually exposing them to outdoor conditions over the course of a week. This will help them adjust to the change in temperature and reduce the risk of transplant shock.

When transplanting, space the seedlings about 12-18 inches apart, allowing enough room for the celeriac to grow. Dig a hole slightly larger than the root ball of the seedling and gently place it in the hole. Backfill the hole with soil, firming it gently around the seedling to ensure good contact between the roots and the soil.

Water the newly transplanted seedlings thoroughly and keep the soil consistently moist throughout the growing season. Mulching around the plants can help retain moisture and suppress weeds.

With proper care and attention, your celeriac plants will thrive and produce delicious, flavorful roots that can be harvested in late summer or early fall.

Watering and Fertilizing

Proper watering and fertilizing are essential for the successful growth of celeriac. Here are some tips to ensure your celeriac plants receive the right amount of water and nutrients:

Watering

Celeriac plants require consistent moisture to thrive. It is important to keep the soil evenly moist, but not waterlogged. Overwatering can lead to root rot, while underwatering can cause stunted growth and poor root development.

Water your celeriac plants deeply once or twice a week, depending on the weather conditions. If the soil feels dry to the touch, it’s time to water. Aim to provide about 1 inch of water per week, either through rainfall or irrigation.

It is best to water celeriac plants at the base, avoiding wetting the foliage. This helps prevent the spread of diseases and reduces the risk of fungal infections.

Fertilizing

Celeriac plants benefit from regular fertilization to ensure they receive the necessary nutrients for healthy growth. Before planting, incorporate well-rotted compost or aged manure into the soil to improve its fertility.
