Keloos

Celery

90d to harvest

Crisp as fresh-cut rain on stone, Keloos celery forms tall, tightly gathered stalks with a clean, bright snap and a pleasantly mellow, sweet celery flavor. The texture stays tender and refined through the season, making these stalks especially satisfying for bold, aromatic use in salads, slaws, and savory mixes, as well as for classic pickling and quick flavoring in sauces. Grow Keloos for a garden harvest that feels polished—straight, upright, and consistently crisp at about 90 days.

Frequently Asked Questions

What’s the most common problem on Apium graveolens var. dulce (kaleos/celery-type), and how do I treat it?

A common issue is early blight–like foliage spotting and leaf diseases that show up as dark, spreading spots on leaves in humid weather. Remove infected leaves early, water at the soil line (not over the foliage), and improve airflow between plants in your part-sun bed. If spots persist, use an approved garden fungicide labeled for celery/Apiaceae according to the label rate, starting as soon as symptoms appear.

How often should I water keloos during its main growing phase?

During the main growth period (after seedlings establish until the last several weeks), keep the soil evenly moist—aim for consistently damp soil down to about 6–8 in. Water about 1–2 times per week, increasing to more frequent watering during hot spells, but never let the soil fully dry out. Mulch helps prevent swings, which are a common cause of tough stalks and poor flavor in celery-type crops.
