Giant Prague Celeriac

Giant Prague Celeriac is a flavorful twist on a classic root vegetable! Also Known As: Celery Root, this white, knob-shaped, tender, aromatic root has flavorful stalks, leaves, and blades that are aesthetically elegant and bright. This ingredient has been favored among European chefs; it can be mashed into Celery Root puree, sliced into soups and casseroles, and used as a garnish. The root, leaves, and stalks are all edible and have a distinctive mild, nutty, and celery-like flavor that is used to add depth and aroma to soups, stews, purees, and roasts. Harvest when knobs are 4"-5" in diameter or tear leaves and stalks as need for a touch of European flair.

Also Known As: Celery Root, Turnip-Rooted Celery, Knob Celery, Root Celery, Celery Knob, Celery Tuber, Turnip-Root Celery, German Celery, Sellerie-Knolle.

Planting Instructions:

Soil Preparation:

Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 8-12 inches deep. Loosening the soil will help the plant establish strong roots.

Plants grow best in soil with lots of organic matter. You may optionally add fertilizer or organic material such as compost, leaves, or rotted hay to mix into the soil at this point. For small gardens, scatter 2-3 tablespoons of fertilizer evenly and work into the top 2-3 inches of soil for each hill or 2 foot by 2 foot planting area. For larger gardens, scatter 2-3 pounds of a complete fertilizer for each 100 square feet of planting area. Work fertilizer or organic material into the soil and leave the surface smooth.

Form rows of soil beds 4-6 inches high and at least 2 feet apart. This formation of ridges will help with drainage.

Celery can also be planted in a grid formation to better shade celery plants and promote blanching.

Planting:

Celery grows best in cool temperatures, with an ideal growing range between 55-75F. Temperature above 80F can cause celery to bolt.

Starting Indoors: For an earlier harvest, you may optionally start planting indoors in containers 8-10 weeks before the last expected frost date in Spring. Harden off then transplant seedlings outdoors in a sunny location when the soil temperature is above 50F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the holes, burying roots in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting.

Directly Sowing: If directly sowing outdoors, plant in spring when the soil warms to at least 50F. For fall crops, direct sow seeds outdoors 10-12 weeks before the first frost. To plant, make holes 1/4 inch deep and spaced 8 inches apart down the rows of raised beds. Plant 2-3 seeds per hole. If choosing to thin to the strongest plant, determine the strongest and healthiest plant, then remove all other plants, narrowing to a single plant per hole. Cover seeds thinly with soil and water after planting.

Planting Depth:	1/4 inch
Within-Row Spacing:	8 inches
Between-Row Spacing:	2 feet

Care During the Season:

Watering: Water the plants deeply, soaking the soil to a depth of 6-8 inches, once a week. If there is no rainfall, water 2 times a week. Sandy soils may need to be watered more often than heavy clay soils.

Weeding: Keeping plants weed-free improves production. If plowing or hoeing, do not dig deeper than 1 inch to prevent from cutting the feeder roots.

Fertilizing: Once seedlings are established, 3-4 weeks after planting, you may optionally apply a light dressing of fertilizer, without letting the fertilizer touch the plants. Water plants after fertilizing.

Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options that can be used for prevention. Sulfur also has fungicidal properties and helps in controlling many diseases. Before using a pesticide, read the label and follow cautions, warnings and directions.

Diseases: If spots or mold appear, treat plants with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. When using fungicides always follow label directions.

Harvesting:

Harvest Celeriac when the roots are about 4-6 inches in diameter and firm, about 90-120 days from planting. The best time to harvest is in the fall, before the first hard frost, as the root continues to grow and develop flavor as the weather cools. Carefully dig around the base of the plant with a spade or fork, being cautious not to damage the root. Cut off the leafy stalks and any smaller roots before storing. Celeriac can tolerate light frosts, so it can be left in the ground until the weather becomes too cold. Store celeriac in a cool, dark place with good ventilation.
