Understanding Celery Plants in Detail

Celery plants (Apium graveolens) belong to the Apiaceae family and are popular for their crunchy texture and nutritional value. Here are some key characteristics of celery plants:

Characteristics of celery plants

  • They have long, hollow stalks that grow above the ground.
  • The leaves are bright green and feather-like, while the flowers are small, white, or yellow.
  • Celery plants are biennial, meaning they complete their life cycle in two years.
Characteristics of celery plants

Lifespan of celery plants

  • Celery has a lifespan of two years, but they are usually grown annually and harvested within a single growing season.
  • If left to flower and produce seeds, celery plants will die at the end of their second year.

Ideal soil and growing conditions for celery

Celery plants require well-draining, adequately aerated loamy-type soil rich in organic matter. Sandy soils are also suitable, but anything with heavy clay should be avoided as they can cause drainage problems. The ideal soil pH range for celery is between 6.0 and 7.0.

Before planting celery, preparing the soil by adding organic matter such as compost, aged manure, or leaf mold is important. This will help improve soil structure, fertility, and water-holding capacity.

A soil test can also help determine the pH level and any nutrient deficiencies, which can be corrected by adding amendments such as lime or fertilizer.

Regarding growing conditions, celery requires full sun exposure, but it can tolerate some shade in hotter climates. The optimal temperature range for growing celery is between 60-75°F (15-24°C).

It’s important to provide consistent moisture to these plants, as they require regular watering to maintain their crisp texture and prevent stress.

Watering should be done deeply and regularly to keep the soil evenly moist but not waterlogged, as this can lead to root rot and other problems.

Celery plants also benefit from regular fertilization with a balanced blend high in nitrogen, phosphorus, and potassium. Fertilization should be done according to the plant’s growth stage, with more frequent applications during the vegetative stage and less during the reproductive stage.

Mulching around the base of the plants can also help retain moisture and suppress weeds while providing additional organic matter to the soil.

Common pests and diseases that affect celery

Celery is susceptible to several pests and diseases, which can damage or even kill the plant if left untreated. Here are some common ones to watch out for:

Common pests and diseases that affect celery


  • Aphids: These tiny, pear-shaped insects suck celery plants’ sap and life out, causing the leaves to curl and distort. They can also transmit viruses that further damage the plant.
  • Cutworms: These larvae of various moth species cut through the stems of young celery plants, causing them to wilt and die.
  • Spider mites: These small, spider-like insects feed on the undersides of celery leaves, causing yellowing and stippling. They can also produce webbing that further damages the plant.
  • Thrips: These tiny, slender insects feed on celery leaves and flowers, causing silvery streaks and distortion. They also transmit viruses that can affect the plant’s growth and productivity.


  • Bacterial blight: This disease causes brown, water-soaked spots on celery leaves and stems, which can eventually lead to wilting and death. It’s caused by a bacterium that thrives in warm and humid conditions.
  • Fusarium wilt: This soil-borne disease causes the yellowing and wilting of celery leaves, which can spread to the entire plant and cause it to die. It is caused by a fungus that can survive in the soil for several years.
  • Septoria leaf spot: This fungal disease causes circular, grayish-brown spots on celery leaves, which can merge and cause the leaves to drop prematurely. It can also affect the stalks and cause them to rot.

Growth stages of celery plants

To properly harvest celery without killing the plant, it’s important to understand its growth stages. This will help you determine when the plant is mature enough for harvest and how to care for them during each growth stage.

In the following section, we’ll dive into the different growth stages and what to look for in each stage.

Growth stages of celery plants

Germination and seedling stage

The germination and seedling stage is the first phase in the life cycle of celery plants. During this stage, the seeds will sprout and develop into small seedlings.

This stage typically lasts about 3-4 weeks after planting, depending on the temperature and moisture levels. At this stage, the seedlings are vulnerable and should be protected from pests, diseases, and extreme weather conditions.

Vegetative stage

The vegetative stage is the period that focuses on growing leaves and developing a strong root system. This stage typically lasts around 10-12 weeks after planting.

At this stage, the celery plant will develop sturdy stalks and large, dark green leaves. It’s important to provide consistent moisture and fertilization during this stage to ensure proper growth and development.

Reproductive stage

The reproductive stage is when the celery begins producing flowers and seed heads. This stage typically occurs around 16-18 weeks after planting. It’s important to remove the flowers and seed heads from celery plants, as they can divert energy away from producing edible stalks and reduce the quality of the crop.

Maturity stage

The maturity stage is the final phase in the life cycle of celery plants. This is when the stalks reach their full size and are ready for harvest. Depending on the growing conditions, this stage typically occurs around 18-20 weeks after planting.

Harvesting celery without killing at the right time is important to ensure the best quality and flavor. Overripe celery stalks can become woody and less palatable.
