Not only is garden celery better-tasting than store-bought types, but also it’s less chemically-laden. In Minnesota, plant celery before other crops or when the soil is from 40-50 degrees. This cool-weather crop requires 16 weeks of cool weather to come to harvest. Celery is considered a hardy biennial, but it’s grown as an annual which is mainly grown for its edible 12- to 18-inch stalks.
- Begin acclimatizing celery to the outdoors two weeks before planting: Leave your plants outside for progressively longer each day, taking care to bring them back under cover if frost threatens.
- Work organic compost into the soil prior to planting.
- Water thoroughly.
