Celery should be kept in the refrigerator, but it often goes limp within a few days. While you can use celery long after it becomes limp, it is best when it is still fresh and crisp, especially if you're eating it raw. Fortunately, there is a simple storage technique to keep celery fresh longer than just a few days after purchasing or harvesting.
Select a fresh bunch of celery, which is essential to longer storage. Bunches should be compact. The stalks should be light green, firm and crisp, not wilting or like rubber. The leaves should be bright green.
Cut off the base of the celery and leaves. Throw out any damaged stems. Rinse the stalks in water to get off any dirt and sand.
Place the stalks in a plastic bag. There’s no need to dry them as they will keep better slightly moist. Put the celery in the vegetable storage bin in your refrigerator. Keep the bag toward the front of the drawer because often, celery freezes near the back of the refrigerator, rendering it limp and watery after thawing. Celery stored in this manner should remain fresh and crisp for about 10 days.
Freeze cooked celery in freezer bags. Boil cut celery for about 2 to 3 minutes, drain and cool. You can use frozen celery for soups and as an added ingredient in recipes such as chicken and rice. Use frozen celery within a year.
Fill a wide planter with rich potting soil. Celery does best in nutrient-rich soil.
Mix the celery seeds with sand and spread them evenly over the potting soil. Then, cover the seeds with a thin layer of potting soil.
Put your planter in a north- or east-facing window. Keep the soil moist, but not soaked.
After about 2 weeks, transfer the sprouted plants into individual containers. Pull them out carefully to avoid damaging the roots.
Fertilize the celery with a fertilizer such as the one linked to below. Add it according to instructions.
Let the celery grow for 100 days. Then, harvest it by pulling the whole plant up.
Celery stalks should be harvested when they are 12 inches in length; entire celery plants should be harvested when they have reached 3 inches in diameter.
