  • Merengo F168–92 days

    Vigorous; 28” tall

    Resistance: HR: Fusarium Yellows

    Early variety with compact plants for easy packing. Robust plants grow quickly and have good flavor and texture. Tall, dark green stalks with healthy tops. Performed extremely well in our trials through wet conditions. Comparable to Calypso. Pelleted seed only.

    Growing notes: Days to maturity are from spring transplanting. Celery and celeriac can be a challenging crop for beginning growers. These crops require a very long growing season with heavy feeding and a steady water supply. Transplanting is highly recommended; start seeds indoors 10-12 weeks before planting date. Optimal soil temperature for germination is 70-75°F and tiny seeds require shallow planting. Harden off plants by reducing water for one week. Do not decrease temperature, as a ten day period with nights below 40°F and days below 55°F can cause bolting. Transplant when outside temperatures are consistently over 50°F. In hot climates, celery may require partial shade. Celery is commonly blanched by covering plants, hilling with soil or planting close together. After harvest, cool stalk heads immediately in water and store at 34°F with 95% relative humidity for up to two weeks.

When to feed, prune & water

Attract beneficial insects and protect pollinators

Protection
  • Routine carePlant insectary flowers and tolerate light pestsstrong evidence — extension confidence

    Grow a diversity of flowering plants (including small-flowered umbels and asters) to feed predators and parasitoids, and tolerate low pest numbers so natural enemies have prey to stick around.

    Source: UC IPM; UMN Extension

  • Routine careNever spray open bloomsstrong evidence — extension confidence

    Avoid insecticides on flowering plants and apply any needed sprays in the evening when pollinators aren't active, and favor selective products over broad-spectrum ones to spare bees and beneficials.

Keep celery consistently moist in rich soil

Watering
  • Routine careNever let celery dry out· every 2 daysstrong evidence — extension confidence

    Celery is shallow-rooted and very water-demanding, so keep the soil evenly moist at all times; uneven watering leads to stringy, bitter, hollow stalks. Grow it in soil enriched with plenty of organic matter and mulch to hold moisture between waterings.

Mulch to suppress weeds and retain moisture

Mulch
  • Routine careApply organic mulch around plantsstrong evidence — extension confidence

    Spread a few inches of straw, shredded leaves, or compost around established plants (keeping it off stems) to hold soil moisture, suppress weeds, and moderate soil temperature; wait until soil has warmed for heat-loving crops.

Plan crop rotation

Rotation
  • Routine careRotate plant families between bedsstrong evidence — extension confidence

    Avoid planting the same family in the same bed in consecutive years (aim for a 3+ year gap), grouping crops by family so soilborne diseases and pests that build up don't carry over to the next susceptible crop.

    Source: UMN Extension; Cornell

  • Routine careSequence for soil healthmoderate evidence — extension confidence

    Follow heavy feeders like tomatoes and brassicas with legumes or a cover crop to support soil fertility and structure, and keep simple notes each year so you can track where each family grew.

Describe what you see on your celeryand we'll rank the likely causes — most likely first, least-invasive fix first.

Bacterial soft rot

Diseasesevere

Symptoms: mushy water-soaked decay of fleshy tissue; slimy soft rot of heads, bulbs, roots, or fruit; foul odor from rotting tissue; rapid collapse after wounding or in warm wet conditions; rot spreading in storage

  • CulturalRemove rotting plants and produce (manage, not cure)strong evidence — extension confidence

    Soft rot can't be cured once tissue breaks down; promptly remove and discard affected plants and produce so the bacteria don't spread to neighbors or other stored vegetables.

    Source: Cornell NYS IPM

  • CulturalAvoid wounds and excess moisturestrong evidence — extension confidence

    Harvest in dry conditions, handle gently to avoid bruising, control insects that create entry wounds, and improve drainage; cure and store bulbs and roots cool and dry.

    Source: Cornell NYS IPM

  • CulturalDon't overwater and rotatemoderate evidence — extension confidence

    Avoid waterlogged soil and overhead watering that splashes bacteria, and rotate away from previously affected fleshy crops to lower disease pressure.

Southern blight

Diseasesevere

Symptoms: sudden wilting in hot weather; yellowing then collapse of whole plant; white fan-like mold mat at the stem base and soil; tan-brown mustard-seed-sized sclerotia near soil line; girdled rotted lower stem

  • CulturalRemove infected plants and surrounding soil (manage, not cure)strong evidence — extension confidence

    Once a plant collapses it can't be cured; dig out the plant plus the top few inches of nearby soil containing sclerotia and dispose of it, avoiding spread on tools.

  • CulturalBury residue and rotatemoderate evidence — extension confidence

    Deep-turn soil to bury sclerotia, remove crop debris at season end, and rotate susceptible solanaceous and legume crops with grasses for several seasons.

    Source: Clemson Land-Grant Press

  • CulturalAdjust soil pH and plant earlymoderate evidence — extension confidence

    Maintain soil pH at the level recommended for the crop, since the disease is worse in low-pH soils, and time plantings so harvest begins before peak summer heat favors the fungus.

White mold (Sclerotinia stem rot)

Diseasesevere

Symptoms: water-soaked stem or branch lesions; fluffy white cottony mold on stems and pods; sudden wilting of part of a plant; hard black sclerotia inside or on stems; collapse during cool wet bloom periods

  • CulturalRemove infected plants (manage, not cure)strong evidence — extension confidence

    There's no cure for an infected plant; cut out and bag affected plants including the black sclerotia, and don't compost them, since sclerotia survive years in soil.

    Source: UMN Extension; UC IPM

  • CulturalOpen the canopy and rotatestrong evidence — extension confidence

    Space plants widely, control weeds, orient rows to prevailing wind, and avoid overhead watering at bloom to dry the canopy; rotate to non-host crops (corn or other grasses) for several years.

    Source: UMN Extension; UC IPM

  • CulturalWater at the base, not overheadmoderate evidence — extension confidence

    Use drip or soaker irrigation to keep foliage and the soil surface drier, which discourages the sclerotia germination and mycelial growth that drive white mold.

Carrot rust fly

Pestmoderate

Symptoms: rusty brown tunnels through carrot roots; stunted reddish foliage

  • CulturalRow cover + delay sowingstrong evidence — extension confidence

    Cover the bed with insect netting from sowing, and avoid the spring egg-laying peak by sowing a little later. Crop rotation helps.

Celery blackheart (calcium disorder)

Disordermoderate

Symptoms: brown to black decayed young leaves at the center of the plant; dying growing point while outer stalks look fine; soft rot developing in the heart; problem worse in hot, dry, fast-growing conditions

  • CulturalSteady the water supplystrong evidence — extension confidence

    Blackheart is a calcium disorder caused by calcium not reaching the fast-growing heart, usually triggered by uneven soil moisture and hot weather rather than low soil calcium. Keep soil moisture even with regular watering and mulch, and avoid heavy nitrogen pushes that force rapid growth.

Celery leaf spot (early and late blight)

Diseasemoderate

Symptoms: small yellow then brown spots on leaves and stalks; spots enlarging with tiny black specks in the center (late blight/Septoria); ashy gray lesions (early blight/Cercospora); spots merging until foliage browns and dies

  • CulturalSanitation and dry foliagestrong evidence — extension confidence

    Early blight (Cercospora) and late blight (Septoria) are fungal leaf spots that spread in wet foliage; use disease-free seed, remove infected leaves and end-of-season debris, water at the base, and rotate out of the carrot family. Space plants for good airflow so leaves dry quickly.

Root rot from overwatering / poor drainage

Diseasemoderate

Symptoms: stunted yellowing plants that wilt despite wet soil; soft brown mushy roots; sloughing root outer layer leaving thread-like core; poor growth in low or compacted wet spots; seedlings collapsing at the soil line

Tarnished plant bug / lygus

Pestmoderate

Symptoms: deformed or puckered new growth; pitted or scarred stems and leaves; aborted or misshapen buds and fruit; catfaced or dimpled strawberries; small bronze-green bugs with triangular back marking

  • CulturalManage surrounding weedsstrong evidence — extension confidence

    Keep broadleaf weeds mowed or removed around the garden, since lygus build up on flowering weeds and move to crops as those weeds dry down; avoid mowing large weedy areas right beside fruiting crops at bloom.
