Celery Plants FAQs

Take a look at some of the frequently asked questions we receive from those looking to buy Celery Plants in the UK. You can  contact our Customer Service Team or browse our general FAQs for further advice.

When to plant Celery Plants

The best time to plant celery plants in the UK is in late spring to early summer, typically from May to June, once the risk of frost has passed and the soil has warmed up. Celery thrives in cooler temperatures, so starting seeds indoors in February or March is common, allowing the seedlings to develop before transplanting them outdoors. For optimal growth, ensure the planting site has consistent moisture and is rich in organic matter.

How to Plant Celery Plants

To plant celery plants, choose a sunny spot with moist, nutrient-rich soil that retains water well. Begin by preparing the soil with plenty of organic compost or well-rotted manure to ensure it is fertile and retains moisture. If starting with young plants, space them 25–30 cm apart in rows that are about 30 cm apart to give them room to grow. Transplant seedlings when they are about 10–15 cm tall, ensuring the crown sits just above the soil level. Water thoroughly after planting and maintain consistent moisture throughout the growing season, as celery requires steady hydration to prevent bitterness. Adding a layer of mulch can help retain soil moisture and suppress weeds. Feed with a balanced fertiliser every few weeks for healthy growth. Celery is ready to harvest in 10–12 weeks once the stalks are firm and crisp.

How long do Celery Plants take to grow

Celery plants typically take 10 to 12 weeks to mature after transplanting, depending on the variety and growing conditions. If growing from seeds, it takes an additional 8 to 10 weeks for the seedlings to develop before they are ready for transplanting, making the total growing time 18 to 22 weeks. Celery requires a long, cool growing season and consistent care, including regular watering and feeding, to ensure the stalks grow firm and crisp.

Why Grow Celery Plants?

Growing celery plants is a rewarding way to enjoy fresh, flavourful stalks straight from your garden. Homegrown celery often tastes better than store-bought varieties, with a crisp texture and rich flavour that enhances soups, salads, and snacks. Celery is highly nutritious, low in calories, and packed with vitamins such as K, A, and C, as well as dietary fibre and antioxidants. It’s a versatile crop that can be grown in vegetable patches, raised beds, or containers, making it suitable for gardeners of all levels. Additionally, celery is an excellent choice for those who want to reduce food waste, as the entire plant—from stalks to leaves—can be used in cooking.

Where can you grow Celery Plants?

Celery plants can be grown in sunny to partially shaded locations with moist, fertile soil that retains water well. They thrive in vegetable gardens, raised beds, or large containers, provided the soil is rich in organic matter. Celery requires consistent moisture, so it's important to grow it in areas where the soil won’t dry out quickly. It is best suited for regions with cool summers or temperate climates, as extreme heat can cause it to bolt. Celery also adapts well to greenhouses or polytunnels, making it a versatile option for gardeners in cooler or unpredictable climates.
