Tendercrisp Celery Seeds

$2.29
Tendercrisp is a popular heirloom celery that produces flavourful heads of an extra-large size that keep well in the garden until late in the season. The plants grow dark-green stalks that measure about 12 inches at first joint and the mature plants reach about 3 feet tall.

Somewhat resistant to poorer soils and diseases, Tendercrisp is one of the easiest celeries to grow from seeds. The stalks and leaves have a traditional celery flavour and are tasty both raw and cooked. A truly versatile plant that can be harvested at any stage of growth.

GROWING INSTRUCTIONS

Dense hearts of tall green stalks will reward the home gardener who accepts the challenge of growing this long season, cool weather vegetable. To get a head start on the season, celery seeds should be started 10-12 weeks before the last spring frost.

Spread seeds in flats, about 2 cm apart. You can firm the seeds into place, but there is no need to cover with soil. Celery seeds will require light to germinate, usually taking about 2-3 weeks. Set under lights for 16 hours/day and keep seeds moist by misting and/or bottom watering. Try to keep the ambient temperature an ideal 21°C.

When seedlings develop their second true leaf, either thin them out or transplant individuals into deeper pots. Prepare for transplanting by hardening off the young plants. Reduce watering a bit and expose gradually to the sun and outdoor elements. Cold weather can cause celery to bolt, so wait until night time lows stay above 4°C. Seedlings can be transplanted into the bed about 20-25 cm apart, water well.

Celery will thrive in cooler temperatures, rich soil and under full sun. Because of its shallow roots, mulch, thorough waterings and top dressing with fertilizer are good practices to enrich overall plant health.

Stalks can be tied together to keep from spreading. Practice blanching by covering or wrapping stalks with brown bag paper or cardboard. Do not cover the leaves. Sheltering from the sun will help prevent the development of bitter tasting stalks.

Celery can take up to 100 days to harvest. The whole bunch can be cut at once, but individual stalks can be continually picked throughout the fall until the last frost. Harvest stalks from the outside in when stalks reach 8 cm tall and enjoy a long season of celery's refreshing ribs.

QUICK FACTS

- Celery has been cultivated for its seeds and leaves since antiquity as an aromatic and medicinal plant. The Italians domesticated celery as a vegetable in the 1500s, resulting in selections with solid stems.

- Celery seeds will remain viable for 3 years if stored in a cool, dark place, ideally between 4 and 10⁰C. After that, the germination rate may start to go down.
