Plants to Avoid
Growing Celery From Seed
If you would like to grow celery from seed, it’s really quite simple to do if you start it indoors to give it a head start. Here are the best tips and tricks for growing celery from seed:
- Start indoors in peat pots or cell trays. Celery takes 20-30 days to germinate, so starting 8-12 weeks before the last frost date for your area is ideal.
- Sow the seeds no more than 1/4″ deep, since they are very small seeds.
- Plant 2-3 seeds per pot, thinning to the strongest plant after the seeds germinate. Since the seeds take so long to germinate, this is an insurance policy to make sure each cell has a plant.
- Transplant your plants into the garden 2-3 weeks before the last frost date, hardening them off for several days before you make the transplant.
- Celery does best in cool climates, so those in southern regions may have more success growing it as a Fall crop.

If starting your celery from seed, you will need to start it indoors 8-12 weeks before your last expected frost date.
How far apart should celery be planted?
Individual plants should be spaced at least 12″ apart, with rows being at least 18″ apart, or more if you plan on harvesting between them.
In square foot gardening, you will need 1 square per celery plant.
Does celery need full or partial sun?
Celery requires full sun, which works out to at least 6-8 hours of direct sunlight per day.
Growing Celery in Containers
If you would like to grow celery in containers, you can absolutely do that with a few tips, tricks, and best practices.
- Container width – choose a container or pot that is at least 10″ in diameter. Celery is a large plant, and needs plenty of room to grow in.
- Pot depth – select a pot that is at about 8″ deep. While celery does not have long roots, it is a heavy feeder and will need lots of compost to pull nutrients from.
- Fertilize frequently – since celery is a heavy feeder, growing it in a container is going to mean frequent applications of all purpose garden fertilizer. Once every 1-2 weeks is a good place to start.
- Water frequently – the unique challenge of container gardening is that it requires frequent watering unless there has been significant rainfall. Water any time you notice the top 1″ of soil has dried out.
- Location – set your container outside in a spot that gets 6-8 hours of direct sun per day. A south facing slope is always the best option, but any sunny spot will do.
- Harvest – You can either remove the plant completely, or cut off the stalks and leave the bottom root in place in the hopes of getting some regrowth and a second, smaller harvest.
