Common Spinach Varieties

Popular cultivars to look for at your local nursery or seed supplier.

Bloomsdale Long Standing

savoy 48d

Savoy (crinkled) heirloom spinach with thick, crumpled leaves; bolt-resistant and reliable.

Space

flat-leaf 40d

Smooth-leaved hybrid that resists bolting better than most; popular for spring and fall growing.

Malabar Spinach

heat-tolerant

Heat-tolerant tropical vine that thrives in summer when true spinach bolts; glossy, mild leaves.

New Zealand Spinach

heat-tolerant

Not a true spinach but produces similarly; very heat- and drought-tolerant groundcover.

Common Spinach Problems

What to watch for — and how to fix it before it spreads.

🐛

Pests

Leafminer

Larvae tunnel between leaf surfaces leaving white, serpentine trails; mines make leaves inedible.

Fix:

Remove and destroy mined leaves immediately; use row covers; practice crop rotation.

Aphids

Green colonies on undersides of leaves; transmit cucumber mosaic virus.

Fix:

Spray with insecticidal soap; use row covers in spring; plant away from infected cucurbits.

🍂

Diseases

Downy Mildew (Blue Mold)

Yellow patches on upper leaf with purple-gray spores on undersides; spreads rapidly in cool, wet weather.

Fix:

Plant resistant varieties; avoid overhead irrigation; ensure good airflow; apply copper fungicide.

Damping Off

Seedlings collapse at the soil line; caused by Pythium or Fusarium in wet, cool soils.

Fix:

Improve drainage; use sterile potting mix for starting seeds; avoid overwatering.

💡

Common Mistakes

Growing in summer

Spinach bolts (flowers) almost immediately when days exceed 13–14 hours or temps go above 75°F.

Fix:

Grow as a cool-season crop in spring (early) and fall; try heat-tolerant Malabar spinach in summer.

Planting too shallow

Spinach seeds need good soil contact; too-shallow seeding leads to poor, patchy germination.

Fix:

Sow 1/2 inch deep; press soil firmly over seeds; keep moist until germination.

🌾 Seed Saving Guide

🟡 Moderate

✅ Open-pollinated — seeds grow true to parent

When to Harvest Seed

Let plants bolt in heat and allow seed stalks to dry fully before harvesting.

Processing

Strip dried seed stalks, thresh to release seeds, winnow to remove chaff.

Seed Viability

Up to 3 years when stored cool, dark, and dry.

Pro Tip

Spinach is wind-pollinated and dioecious — you need both male and female plants. Isolate by 1000 feet for pure seed.
