Celery is a long-season crop that can be tricky to grow, some might say, the trickiest of all. It likes fertile soil, cool temperatures, and constant moisture. It will not tolerate heat and can be hard to transplant. Summer crops in the north and winter crops in the south make celery a year-round producer. All the work is worth it when you harvest crunchy, green stalks.

Planting

  • Celery seeds should always be started indoors for the best success rate, 8 to 10 weeks before the average last frost date for your area.
  • For summer gardeners, a late summer direct sowing is possible. Be sure that temps will stay between 55 and 70ºF throughout growing period.
  • The National Gardening Association recommends soaking seeds in warm water overnight prior to planting, to reduce germination time.
  • Work organic fertilizer or compost into the soil prior to planting.
  • Harden off seedlings before transplanting by reducing water slightly, and keeping them outdoors for a couple hours a day.
  • Transplant seedlings 10 to 12 inches apart, direct sow seeds ¼ inch deep. These will need to be thinned to 12 inches apart when they reach about six inches high.
  • Mulch and water directly after planting.

Care

  • Celery is a heavy feeder. It also requires lots of water. Make sure to provide plenty of water during the entire growing season, especially during hot, dry weather.
  • If celery does not get enough water, the stalks will be dry, and small.
  • Add plenty of compost and mulch around the plants to retain moisture.
  • Fertilize regularly. Add mulch as needed, to help retain soil moisture and add nutrients.
  • Tie growing celery stalks together to keep them from sprawling.

Pests

Harvest/Storage

  • The parts of celery that are harvested are mainly the stalks, which will be above ground.
  • Harvest stalks from the outside in. You may begin harvesting when stalks are about 8 inches tall.
  • Celery can be kept in the garden for up to a month if soil is built up around it to maintain an ideal temperature. Note: Celery will tolerate a light frost, but not consecutive frosts.
  • Tip: The darker the stalks become, the more nutrients they will contain. Texture changes with color, dark green stalks will be tougher.
  • Keep celery in a plastic bag, in the refrigerator. It should be used within two weeks.

Recommended Varieties

  • ‘Utah’ good for gardeners with limited space. Will only reach 18 inches tall.
  • ‘Alfina’ slender stalks, dark green, quick variety (60 days to maturity)
  • ‘Conquistador’ is tolerant of higher temps and watering shortage.

By Rik Nelsonn

I have planted Celery for the first time, and everything was going well. But when I looked at my plants yesterday I saw that the stalks that are growing in the middle are turning black and rotting on the tops. It's only the ones in the middle. everything else looks fine. Can you tell me how to fix this? thanks.

This problem is called

By Almanac Staff

This problem is called Blackheart and associated with soil calcium deficiency. Usually, this happens when there's inconsistent moisture such as a drought and not enough water or rainy times with too much water. There's not a lot you can do at this point except to water consistently and mulch to conserve moisture. To avoid this problem in the future, test your soil and add gypsum or limestone if soil is calcium deficient. Also, you can plant disease-resistant varieties. Your local cooperative extension can provide a soil test.

You can also grow it indoors. I was surprised to hear this! Here is a link on how you can, it actually works, I've done it. http://www.17apart.com/2012/02/growing-celery-indoors-never-buy-celery.html?spref=fb

 It's not a common vegetable

By Almanac Staff

 It's not a common vegetable in the home garden because celery needs 5 or 6 months of cool nights around 50 degrees F and moderate daytime temps of about 60 to 70 degrees. You would need to plant in late fall for harvest during mid-winter.

Hi... As the celery is growing, can you use the above stock leaves, as the plant is growing ?
Thank you.

By Almanac Staff

Yes, you can eat celery leaves--usually, people use them in soups and salds. The leaves have a slight bitter taste so they're often used as a garnish for a sharper taste. Sometimes they are substituted for parsley.

As pesticide usage is

By Almanac Staff

As pesticide usage is different everyone, we advise you to call your county extension agent for the latest recommendations. It's important to know which pests need to be controlled. Pests of celery include aphids, leafhoppers, carrot weevils, flea beetles, leafminers, armyworms and loopers. For aphids, just use insecticidal soaps.  It is most important to control leafhoppers, a common carrier of viruses. Use floating row covers early in the season, too, and collars if cutworms are present. 

I have tried three

By fairbam

I have tried three consecutive celery plants from the base of a bunch bought at the store. They start off growing beautifully - they get tall and leafy and pretty, and then within a week after potting them (indoors), they suddenly just start falling over limp and then basically rot free from the base. What am I doing wrong? Thank you!

We've learned that celery

By Almanac Staff

We've learned that celery plants from the grocery store will not *usually" grow into a healthy, productive plant. What happens is just what you describe: Some small stalks sprout from the nutrient reserves in the basal tissues, and then the experiment comes to an end because the mother crown starts to rot. It's best to grow celery from seed as this is most natural, even though it takes a while.

Just wanted to respond. I

By sheepgal

Just wanted to respond. I grew a celery plant from the root left from a grocery purchase. I left it in a little water until the roots started then planted it outdoors. It grew well and I harvested some of the stalks but being a lazy gardener, left it in the ground over the winter. It sprouted 4 plants off the original and grew fine. I am wondering if I can divide it and replant and then do it all over again this winter. The stalks on the new plants are about 10 inches tall and 1 cm thick. I have harvested off the new plants lightly.

I am a first-time celery

By Lyndsay Haggerty

I am a first-time celery planter and after following my mother's advice, I have thriving celery plants.
Questions though: 1) Do I have to use mulch in my vegetable garden to keep them moist or would frequent watering during dry times be enough?
2) I used Miracle Grow in my water while watering the garden during the first two weeks after planting. Should I continue to mix Miracle Grow in the water?
3) Are elastics safe to use for keeping celery stalks together in the garden?
Thank you!
Lyndsay

Celery needs lots of water

By Almanac Staff

Celery needs lots of water during the hot summer months. Mulch will help keep the moisture in the soil. Celery is a heavy feeder and needs fertilizer. You can also add some compost to the soil. Elastics or rubber bands are ok to use if they are not too tight.

So if I have the second

By Nique

So if I have the second season seed stalks, do I need to do anything to them, or just let them grow and wait for next season to produce edible celery?

In response to your first

By Almanac Staff

In response to your first question ("Do I need to do anything"), you need to give them the care they need AS they grow, such as frequent irrigation--but not excessive water that might cause the roots to slow growth. And fertile muck or soil with high organic matter.
Our sources suggest that you can harvest these second-year stalks about 90 days after transplanting.
Good luck—most sources indicate that this is a challenge to grow.

Is it a perennial or should it be replanted each season? Our second year produced nice stalks but the texture was woody - had a good taste but not very palatable.

By Almanac Staff

Celery is a "biennial." It produces edible stalks in its first year and seed stalks during the second year. It has a fairly long growing season and gets harvested about 90 days after transplanting, but if the plant were left to grow for the second year and were exposed to low temperatures, it would produce a longer stem and a seed head.

seeds wont sprout

By Anonymous

I have planted about 12 peatmoss pods with celery over a month ago and the temp is at 68 and not one has even sprouted. What am I doing wrong?

celery

By Almanac Staff

You are not necessarily doing anything wrong; celery is not an easy crop to grow. You do not indicate where you are, but a temp of 68°F seems a little high, based on our sources. You also do not mention your soil conditions; celery likes lots of organic matter, which means good compost. Peat holds moisture but also brings a certain amount of acidity, which could be too much for celery, which prefers soil of neutral pH. You might consult your local extension service for specific advice for your area. We hope this helps.

I would love to grow celery and collard greens, kale and rhubarb. But all these plants don't toleerate heat and drought well, both which we will have more of with global warming. Those climate change deniers must not be gardeners.

I am an avid gardener in an area where we have heat waves and then cool weather. I have successfully grown kale, celery, broccoli, and other plants that "don't tolerate heat and drought well". I also believe global warming is a farse. There goes your theory.

By Aquaria

Belief isn't science, and the science is solid on global warming.

The "farse" is that our school systems are so utterly bereft of education thanks to believers rather than the reality-based that nobody knows how to distinguish science from fiction anymore.

Which is just how the deluded like it.

as a child my mom says she recalls her mom wrapping the celery with newspaper! Is this a good idea?

I wrap the top 6-8" of mine

By Elizabeth Berman

I wrap the top 6-8" of mine with a doubled over sheet of newsprint and tie it off with a piece of twine. This is called "blanching" the celery, and it works beautifully. I like newsprint best of all because it is compostable.

celery and newspaper

By Almanac Staff

Some people prefer to blanch celery because it makes it taste milder. It also turns the stalks a paler green to white, but makes them less nutritious.

To blanch, you can wrap the stalks with newspaper when the plant is about 11 to 18 inches tall, or about 10 to 20 days before harvest. Allow about 6 or so inches of the leaves to pop out of the top of the newspaper. Tie the newspaper with twine to secure it, and cover the bottom edge with black plastic and then cover with soil. (Direct contact of soil on the stalks may cause them to rot.)

Other gardeners use boards or other materials to block the light from the stalks.

Nowadays, there are self-blanching types of celery. These usually have more leaves, which, if the plants are planted in blocks, are enough to block out light to the stalks for a milder taste.

Older varieties, that offer more intense flavor, might require some form of blanching, such as the above or trenching, to reduce the bitterness.
