How to Grow Celery at Home: A Step-by-Step Guide
From seed to crisp stalks — everything you need to know about growing celery in Greece.

Celery is one of those crops that looks intimidating but rewards patient gardeners with crunchy, aromatic stalks perfect for salads, stews, and fresh juicing. Whether you manage a private home garden, a hotel kitchen plot, or a holiday rental with a small outdoor terrace, growing your own celery in Greece is very doable with the right timing and care. The video above walks through the full growing cycle visually; the steps below give you a precise, climate-aware roadmap you can follow season by season.
Why Celery Suits the Greek Climate (With a Little Help)
Celery (Apium graveolens) is a cool-season vegetable that thrives between 15 and 21 degrees Celsius. In Greece, that sweet spot falls in autumn and spring, making October-to-April the ideal window for most lowland regions and year-round cultivation possible in higher-altitude areas like the Peloponnese interior or central Crete.
During the fierce Greek summer, celery bolts quickly and turns bitter, so timing is everything. Plan your sowing around the shoulder seasons and you will sidestep the worst of the heat entirely.
Choosing Between Seeds and Kitchen-Scrap Regrowth
You have two practical entry points: starting from seed, which gives you full control over variety and timing, or regrowing celery from the root base of a supermarket bunch. The scrap method is faster and almost foolproof for beginners — simply place the cut base in a shallow dish of water on a bright windowsill until roots and new shoots appear, then transplant to soil.
For anyone who wants a reliable, full-sized harvest across multiple plants, starting from seed is the better long-term strategy. Greek garden centres stock celery seed in early autumn; alternatively, order online varieties bred for warm-Mediterranean conditions such as 'Tall Utah' or 'Golden Self-Blanching'.
5 Steps to Growing Celery Successfully
- 1
Start Seeds Indoors 10-12 Weeks Before Transplant
Celery seeds are tiny and slow to germinate — expect 14 to 21 days. Sow them on the surface of a fine, damp seed-starting mix without covering them (they need light to germinate). Keep the tray at around 18-21 degrees Celsius. In Greece, sow indoors from late August through September for an autumn-to-winter crop, or in late January for a spring harvest.
- 2
Transplant Into Rich, Moisture-Retentive Soil
Once seedlings reach 10-15 cm tall with at least three true leaves, transplant them 30-45 cm apart in a bed or large container. Celery is a heavy feeder and needs consistently moist, deeply worked soil amended with plenty of compost. In containers — ideal for balconies and terrace gardens — choose pots at least 30 cm deep and use a high-quality potting mix blended with perlite for drainage.
- 3
Water Consistently and Fertilise Every Two Weeks
Celery is roughly 95 percent water, so irregular irrigation is the single fastest way to ruin a crop. Aim for at least 2.5 cm of water per week, more during dry spells. Drip irrigation is ideal for Greek conditions. Feed with a balanced liquid fertiliser (nitrogen-rich during the first half of growth) every two weeks to support the long, upright stalks.
- 4
Blanch the Stalks for a Milder, Tender Crop
About three weeks before harvest, blanch the plants by wrapping the stems loosely with cardboard, newspaper, or a purpose-made celery collar, or simply mound soil around the base. Blocking light from the stalks reduces bitterness and gives you that pale, supermarket-style crunch. This step is optional if you prefer stronger-flavoured green celery, which is more common in traditional Greek cooking.
- 5
Harvest Outer Stalks Progressively or Cut the Whole Head
Celery is ready to harvest 100-120 days after transplanting. You can harvest outer stalks individually as soon as they are tall and firm, leaving the inner plant to keep growing — this extends your harvest window by weeks. Alternatively, cut the entire head at the base. Store harvested celery wrapped in a damp cloth in the fridge for up to two weeks, or blanch and freeze excess stalks for soups and stews.

FAQ
- Can I grow celery in a pot on my balcony in Greece?
- Yes, celery grows well in containers as long as the pot is at least 30 cm deep and 30 cm wide per plant. Use a rich potting mix, water daily in warm weather, and keep the pot in a spot that gets morning sun but is shaded from the hottest afternoon rays during spring.
- Why is my celery turning bitter?
- Bitterness is almost always caused by heat stress, inconsistent watering, or a failure to blanch the stalks. Make sure you are growing celery in the cooler months in Greece, water deeply and regularly, and consider blanching the stems for the final three weeks before harvest to mellow the flavour.
- How long does celery take to grow from seed to harvest?
- From seed sowing to your first full harvest is typically 130-150 days (roughly 18-20 weeks). If you start from a regrown kitchen scrap that is already rooted, you can cut that timeline by 3-4 weeks. Starting from nursery transplants lands somewhere in the middle.
