How to Grow Celery - The Complete Guide

Celery are a rewarding vegetable to grow at home and an excellent addition to any garden. Below we share the basics of growing celery in a home garden, as well as common mistakes and considerations.

When to Plant Celery

Celery are a frost tolerant vegetable. This means the best time to plant them is mid to early spring, and mid to late summer for a fall harvest. If you’re expecting a late or early frost after planting, protect your celery with a blanket of straw or cover them with plastic buckets.

If you live in the U.S., check out the Farmer’s Almanac or the USDA’s Plant Hardiness Zones for more help regarding frost and the best dates for planting in your area.

How to Plant Celery

Plant your celery seeds directly in the soil of your garden or container at a depth of 0.5 inches (1 centimetre). Seeds can be planted outside or you can germinate them indoors and transplant them later. Typically, celery seeds take about 1 - 2 weeks to fully germinate.

If transplanting, the best time to move celery plants outside is when they reach 3 - 4 inches (7 - 10 centimetres) tall or have at least 3 - 4 true leaves.

When planting celery in the garden, it’s best to space them 1 - 2 feet (30 - 60 centimetres) away from the nearest plant.

How to Grow Celery in Pots

How Long do Celery Take to Grow

On average, it takes about 80 days for planted celery seeds to develop into a fully mature plant.

How Big do Celery Get

Typically, celery plants reach about 8 - 12 inches (20 - 30 centimetres) in height. Though this can fluctuate depending on the variety.

How Much Sunlight do Celery Need

Celery need at least 6 hours of direct sunlight every day in order to thrive. Be careful to place your plants in an area that receives adequate sunlight. Otherwise, they may not mature properly.

How Much Water do Celery Need

Celery like well draining soil that is kept consistently moist, but not wet or soggy. The amount of water it takes to achieve this effect will differ depending on the type of soil available to you.

Be sure to water your celery on a consistent, steady schedule. This will ensure the plant yields a healthy, uniform crop.

If growing your celery in pots, they will need to be watered more frequently than celery planted directly in the garden.

You will know your celery are in need of more water when their leaves wilt, yellow, and/or the plant begins to droop. But be careful, this can also happen if the plant receives too much water. This is a difficult balance for most novice gardeners. But the more time you spend with your celery, the better you’ll be able to gauge how thirsty they are.

How to Harvest Celery

You can pick celery whenever they reach your desired size. Using a sharp knife or scissors, cut the celery at the base and remove from the plant. Cut outside stalks first, and leave smaller stalks to continue growing.
