Yes, growing celery in containers works well once you keep the soil damp at all times. I planted a pot of self-blanching celery on the patio next to the raised bed. The stalks wilted flat by every afternoon. I checked the mix and found it bone dry an inch down by lunchtime. So I slid a saucer under the pot and piled on a thicker layer of mulch. The damp finally held through the hottest part of the day, and those plants stood firm after that. That single fix is the whole secret here.
The catch with celery in pots is that pots dry out far faster than open garden soil. A raised bed holds a deep reserve of water that roots can chase down when the surface bakes. A pot has only the few inches of mix you gave it. Sun and wind pull that moisture out fast, and by noon the roots can sit in dust. Celery hates dry feet more than almost any other vegetable you can plant, and it will tell you within hours.
This plant grew wild in wet marshes and ditches, so its roots expect steady damp ground every single day. To copy those native conditions in a pot, you want a potting mix that holds water well instead of draining the moment you pour it in. I mix in a few handfuls of compost and coconut coir so the soil stays spongy for longer. Then I water often enough that the top layer never bakes hard. A thick mulch cap on top slows down how fast that surface dries between waterings.
Pick a container that is at least 8 inches (20 centimeters) deep so the roots have real room to settle in. Wider beats narrow here, since you want to set several plants close together in one pot. Grouping them this way shades the inner stalks, which keeps them pale and tender on their own. That trick saves you from wrapping each stem by hand later in the season. A pot 12 inches across can hold three or four plants if you keep the feeding up.
You need to feed potted plants more often than you would in the ground. The root system on celery stays small and forages poorly, so it cannot reach far for food the way a deep-rooted plant does. I mix a slow-release fertilizer into the soil at planting time to set a base. Then I add a liquid feed every two weeks through the growing season. That steady drip of nutrients keeps the stalks fat and crisp instead of thin and stringy.
Choose a self-blanching type for any pot, since these stalks stay tender without much fuss from you. Set the pot where it gets full morning sun but a bit of light afternoon shade in a hot climate. Strong midday heat scorches the leaves and speeds up how fast the soil dries between drinks. A spot against an east-facing wall hits this balance well in most yards. The wall throws shade by early afternoon and blocks the dry wind that wicks water away.
Good container celery care comes down to one habit above all the rest. Water daily once the weather turns warm, and check the pot twice a day during a heat spell. Stick a finger an inch into the mix, and if it feels dry, your celery is already stressed and losing crunch. Keep that pot damp, feed it on schedule, and give it the right light. You will pull crisp, pale stalks from a small patio corner that most gardeners leave bare all season.
