GROW WITH US Celery takes patience at the beginning, then asks for steady water and a little attention through summer. Start the seeds indoors, plant out when nights are mild and keep the soil moist. Pick crisp stalks for salads, soups and stews from your own garden. |
Written for home gardeners in Hungary
CHAPTER WELCOME
Your celery season starts here
This book follows the whole journey: seed → seedling → garden → care → harvest → kitchen → next season.
Celery grows slowly from a tiny seed into a leafy plant with crisp, upright stalks. It asks for an early start, fertile soil and dependable moisture through summer. Give it those things, and you can pick fresh stalks for salads, soups and stews from your own garden.
In Hungary, sow celery indoors in late winter or early spring, then plant it outside once the risk of frost has passed and nights are mild. Young plants dislike cold spells, while dry soil can make stalks stringy and strongly flavoured. Keep the soil evenly moist and harvest from late summer into autumn.

The rule for this series: dates guide us, but the plant and the weather make the final decision.
CHAPTER 1
Meet the Celery
Celery is grown for its crisp leaf stalks, which are eaten raw or cooked.
Celery (Apium graveolens var. dulce) is grown for its long, fleshy leaf stalks. The stalks join at the base and form a leafy crown; they are sometimes called ribs or stems in recipes. Celery is related to celeriac, but it does not make the large swollen base that celeriac is grown for. The plants take a long time to grow and need rich soil and regular water.
Celery or celeriac?
|
Celery |
Grown for crisp leaf stalks, or ribs. |
|
Celeriac |
Grown for its swollen base, which is eaten cooked or raw. |
Two close relatives, grown for different parts
· Celery: grown for crisp stalks, which are eaten raw or cooked.
· Celeriac: grown for its swollen base, which is peeled and cooked or grated raw.
· Early sowing: celery has a long growing season, so raise seedlings indoors before spring settles.
· Moisture-loving crop: the soil should stay evenly moist but not waterlogged.
· Leaf stalks: the crisp ribs form where the leaf blades meet at the base of the plant.
· Blanching: reducing light around the stalks can make them paler, milder and more tender.
|
GOOD TO KNOW Celery and celeriac are close relatives, but they are grown for different parts of the plant. This book follows stalk celery, which makes crisp ribs rather than a large swollen base. |
CHAPTER 2
Choose Your Celery
Choose a variety that suits your taste and the amount of space and care you can provide.
Ask yourself five questions
1. Can I start the tiny seeds indoors early in the year?
2. Can I keep young plants warm, bright and evenly watered?
3. Do I have a sunny bed with rich soil that holds moisture?
4. Can I water regularly through warm, dry spells?
5. Would I like to pick individual stalks or harvest whole plants?
A beginner-friendly first planting
|
Start early |
Celery needs a long growing season. |
|
Keep seeds uncovered |
They need light to germinate. |
|
Protect young plants |
Cold spells can trigger early flowering. |
|
Water generously |
Dry soil can make stalks thin and stringy. |
|
A COMMON MISTAKE Covering celery seeds with too much compost. They need light, so press them onto the moist surface and cover only very lightly. |
|
TRY THIS Make a sowing note and mark the date when the first tiny seedlings appear. Celery can be slow, and a record helps you plan next year’s start. |
CHAPTER 3
Let’s Sow
Celery needs a long growing season, so start it indoors. The tiny seeds need light to germinate; press them onto moist compost and cover only very lightly. Keep them warm and be patient, as seedlings may take up to three weeks to appear.
When to sow in Hungary
Sow celery indoors from February to March in a seed tray or small pots. Scatter the fine seeds on the surface of moist compost and press them gently in; add no more than a dusting of compost. Keep the tray warm, ideally above 15°C, and evenly moist. After seedlings grow on, harden them off and plant outside from late May to early June, once cold nights have passed.
What you need
· Fresh celery seeds
· Seed tray or small pots with drainage holes
· Fine seed compost and a clear label
· A warm, bright place for slow germination
· A sunny bed with rich, moisture-retentive soil
Sowing, step by step
1. Fill a tray or pots with fine, moist seed compost and level the surface.
2. Scatter seeds thinly across the surface; press them gently into the compost.
3. Leave uncovered or add only a very light dusting; celery seeds need light.
4. Label the variety and date; keep the compost warm and evenly moist.
5. When seedlings appear, move them into bright light and keep them above 10°C.
|
DON’T PANIC The seeds may take up to three weeks to germinate. Keep the surface warm and moist, and give late seedlings time to emerge. |
|
A COMMON MISTAKE Planting seedlings outside while nights are still cold. Wait for settled mild weather so young celery is less likely to bolt. |
CHAPTER 4
Seedling School
Celery seedlings are small and slow to start. Keep them warm, bright and evenly watered while they grow into sturdy young plants.
Give seedlings light and room
Celery seeds can take up to three weeks to germinate. When seedlings have a few true leaves and are large enough to handle, prick them into individual small pots or thin them to one per module. Handle each seedling by a leaf and keep its roots intact. Give it bright light so it grows strong rather than tall and weak.
Why is germination uneven?
Celery seeds are tiny and need light, warmth and a moist surface. If they are buried, chilled or allowed to dry out, they may be slow to emerge. Keep the tray warm and use a fine spray so the seed is not washed away. Give late seedlings time before giving up on the tray.
Water steadily
Keep seed compost moist but never soggy, and do not let small pots dry out. After planting outdoors, water deeply whenever the soil starts to dry. Celery needs a dependable supply of moisture throughout summer so its stalks can grow full and crisp.
Feeding
Celery is a hungry crop. Prepare the bed with plenty of mature compost before planting. If growth is slow or pale, check that the soil is moist and the plants have enough light. A balanced vegetable feed can support established plants, but follow the product directions.
|
WHAT I WOULD DO I would harden plants off gradually and wait until late May or early June, when the nights are mild, before transplanting outdoors. |
|
DON’T PANIC Celery grows slowly at first. If the plants are healthy, keep watering and feeding; the stalks will thicken as the season progresses. |
CHAPTER 5
Ready for the Real World
Harden off celery plants gradually before planting outside. Young plants are sensitive to cold, so wait for mild nights.
Before planting: check the plants and the bed
1. Choose sturdy seedlings with several true leaves and a healthy centre.
2. Water the pots before planting so root balls hold together.
3. Harden plants off gradually in a sheltered place once days are mild.
4. Prepare a sunny, fertile bed that stays moist but drains freely.
5. Plant at the same depth as in the pot; water in well.
When is it ready in Hungary?
Plant out from late May to early June, once the risk of frost has passed and nights are staying mild. Celery can bolt after prolonged cold while young, so delay planting if a chilly spell is forecast. In cooler parts of Hungary or exposed gardens, use fleece for protection and wait until the weather has settled.
Around Győr, late May or early June is usually a sensible planting window, but check the local forecast rather than relying on a fixed date. Choose a sheltered place that does not dry quickly, and keep the young plants watered as they establish.
|
A COMMON MISTAKE Letting the soil dry repeatedly. Celery needs steady moisture for crisp, full stalks. |
|
GOOD TO KNOW Self-blanching varieties are grown in a close block, where the plants shade one another. You can also wrap outer stalks to make them milder and paler. |
CHAPTER 6
Give Them a Good Home
A fertile bed and consistently moist soil help celery make full, tender stalks.
The right place
Choose a sunny, sheltered spot with fertile soil that holds moisture but drains excess water. Add mature compost before planting. Celery has shallow roots and grows slowly at first, so remove weeds by hand before they compete for water. Rotate the crop and avoid planting it in the same place after celery or celeriac.
Spacing
For self-blanching and green types, space plants about 23 cm apart in each direction, in a block rather than a single row. The plants shade one another and the outside stalks can be wrapped if you want them milder. Follow the seed packet if it gives different spacing; traditional trench varieties need more room.
Planting day
1. Water seedlings and prepare a moist, weed-free bed.
2. Make a hole just large enough for the root ball.
3. Set the plant at the same depth it grew in its pot.
4. Firm gently and water deeply around each seedling.
5. Add a label with the variety and planting date.
Growing in pots
Celery can grow in a large container, but it needs regular watering and plenty of nutrients. Choose a deep pot with drainage holes and fresh, rich potting mix. Space plants about 23 cm apart, or grow one in a roomy container. Check moisture often in summer, as compost dries quickly.
|
TRY THIS Mulch around established plants to slow water loss, but leave a little space around each plant base. |
CHAPTER 7
Water, Feed & Keep Them Growing
Celery is a thirsty, hungry crop. Regular care through summer helps produce full, crisp stalks.
Watering
Keep the soil evenly moist throughout the growing season, especially in warm weather when plants grow quickly. If the bed dries out, celery stalks may stay thin, stringy or strongly flavoured. Water deeply at the soil rather than sprinkling the leaves. Container plants may need daily checks in summer.
Mulch
Once the soil is warm and plants are established, spread mature compost or clean straw around them. Mulch helps hold moisture and suppress weeds. Leave a small gap around each plant base to reduce the risk of rot, and check for slugs beneath the mulch.
Feeding
Celery grows best in fertile soil. Add mature compost before planting, then feed established plants with a balanced vegetable fertiliser if growth needs a boost. Container plants use up nutrients faster, so feed them according to the product label. Water before applying liquid feed.
Keep plants healthy
Weed carefully by hand so you do not damage the shallow roots or stalks. Remove yellow or damaged leaves and check for slugs, snails, leaf-mining damage and leaf spots. Water at the base of the plants and leave enough space for air to move between them.
|
WHAT I WOULD DO I would prepare the bed with mature compost before planting, then water deeply whenever the top layer begins to dry. |
CHAPTER 8
Stalks, Leaves & “What Is That?”
Celery makes a cluster of leaf stalks, or ribs, topped with leafy blades. The whole plant gives clues about how it is growing.
Why are the stalks thin or stringy?
Celery needs a long season, rich soil and steady moisture to make thick stalks. Late sowing, crowded plants, poor feeding or repeated drought can all limit growth. Check that the bed stays moist, the plants have enough space and weeds are not competing with them. If stalks are still small, keep caring for the plant and harvest later.
The beginner’s trouble guide
|
Seeds do not appear |
Celery germination can take up to three weeks. Keep the seed surface warm, bright and moist. |
|
Plants flower too early |
Young celery may have been chilled. Delay planting until nights are mild and protect plants if cold returns. |
|
Stalks are thin or stringy |
Dry soil, crowding, poor soil or late sowing may have slowed growth. |
|
Leaves have pale trails or spots |
Leaf-mining insects or leaf spot may be present. Remove badly damaged leaves and check the plants often. |
|
Stalks are tough |
Harvest at a useful size and keep plants watered; wrapping can help make stalks milder. |
|
DON’T PANIC Celery stalks are naturally green. Blanching is optional and simply makes the covered stalks paler and milder. |
|
A COMMON MISTAKE Waiting until the whole plant is huge before harvesting. You can cut outer stalks as needed and let the centre keep growing. |
CHAPTER 9
Can I Pick It Yet?
Yes—once the stalks are large enough to use, you can pick them one by one or harvest the whole plant.
What “ready” looks like
Harvest when the stalks have reached a useful size and feel firm and crisp. Depending on sowing date and variety, this is usually from late summer into autumn. Cut outer stalks close to the base as you need them, leaving the central leaves to keep growing, or lift the whole plant. Harvest before hard frost damages the crop.
Harvest from late summer
|
Check the stalks |
Choose firm ribs that have reached a useful kitchen size. |
|
Pick outer ribs |
Cut outer stalks at the base and leave the centre growing. |
|
Use what you need |
Harvest gradually from late summer into autumn. |
|
Beat the frost |
Harvest remaining plants before hard frost damages them. |
How often should I check?
Check plants every week from late summer. Pick outer stalks when you need them, and remove any damaged or yellow leaves. If you want paler, milder stalks, wrap the stems of self-blanching varieties with paper or cardboard a few weeks before harvest, leaving the leafy top exposed. Harvest remaining plants before hard frost.
|
READY TO HARVEST? From late summer, check whether the outer stalks are firm and large enough to use. Cut what you need close to the base, leaving the central leaves to grow. If you prefer, lift the whole plant before hard frost. |
|
TRY THIS Try one stalk raw and another cooked. The tender inner ribs are lovely for snacking, while the larger outer ones bring flavour to soups and stews. |
CHAPTER 10
From the Garden to the Kitchen
Celery adds a fresh crunch to salads and a savoury base to soups, stews and many other dishes.
The first rule: wash between the stalks
Separate the stalks and rinse them well, as soil can collect near the base. Trim away any tough or damaged parts. Eat crisp inner stalks raw with dips or slice them into salads. The outer stalks are excellent in soups, stews, sauces and stocks. The leafy tops can also be chopped into cooking.
Match celery to the dish
· Raw and crisp: slice into salads or serve with a dip.
· Soup and stew: chop stalks with onion and carrot for a savoury base.
· Roasted: cut into pieces and roast with other vegetables and herbs.
· Leaves: chop the fresh tops into soups, stocks or sauces.
|
FROM THE KITCHEN A simple celery soup base: finely chop celery, onion and carrot, then cook gently in a little oil until soft. Add stock and potatoes or beans, simmer until tender, and season with pepper and herbs. |
Storing fresh celery
Fresh celery keeps best in the refrigerator. Remove damaged leaves, wrap the stalks loosely and store them in the vegetable drawer. Use them while they remain crisp. If you have a cool, sheltered place and the plants are still in the ground, harvest as needed while frost is not severe.
When you have more than you can use
Chop celery and freeze it for soups, stews and stocks; frozen stalks will soften, so they are not as crisp for salads. You can also cook celery into soup or stock and freeze portions. Use the leafy tops too, or dry them for seasoning.
CHAPTER 11
Next Season Starts Now
Celery is a long-season crop, so notes about sowing, watering and harvest can help you plan better next year.
Keep a tiny garden record
· Variety name and seed source
· Date seeds were sown and seedlings appeared
· When plants were transplanted outdoors
· How consistently the soil stayed moist
· When the first stalks were ready to pick
· Whether stalks stayed crisp and full
· Which dishes you enjoyed it in
Saving seed and planning another crop
Celery is biennial, flowering and setting seed in its second year. Seed saving means keeping a healthy plant through winter and allowing it to flower the following season. It can cross with celeriac and other celery varieties, so keeping seed true to one variety is difficult in a home garden. F1 seed may not come true-to-type. For most gardeners, fresh seed is the simplest choice.
1. Choose a healthy plant with the stalks and flavour you liked.
2. Leave it unharvested and protect it through winter where conditions allow.
3. Allow the plant to flower and form seed heads the following year.
4. Collect dry seed before it falls from the flower heads.
5. Dry fully, label with variety and year, and store cool and dry.
|
GOOD TO KNOW The leafy tops are edible too. Chop fresh leaves into soup or stock, or dry them to use as a savoury seasoning. |
|
WHAT I WOULD DO I would pick outer stalks gradually while the plant is growing, then use or freeze the rest before hard frost arrives. |
