How to Grow Marketmore Cucumbers

Marketmore cucumbers are a dependable slicing variety known for disease resistance and steady production. They’re great for home gardens and especially productive in warm climates like Middle Tennessee.

When to Plant

  • Plant after all danger of frost.

  • Soil temperature should be at least 65–70°F.

  • In Middle Tennessee, that’s usually late April–May.

  • For a fall crop, plant again in late July.

Sun & Location

  • Full sun (6–8+ hours daily).

  • Well-drained soil rich in compost.

  • Slightly acidic to neutral soil (pH 6.0–7.0).

How to Plant

  • Space 6–12 inches apart

  • Rows 3–4 feet apart

Support vs. Sprawl

  • Marketmore is a vining type.

  • Trellising improves airflow and reduces disease.

  • If sprawling, allow 3–4 feet of space per plant.

Watering

  • Keep soil consistently moist (not soggy).

  • Aim for 1–2 inches per week.

  • Water at soil level to prevent leaf disease.

  • Mulch to retain moisture and suppress weeds.

Feeding

  • Mix compost into soil before planting.

  • Side-dress with compost or a balanced fertilizer when vines begin flowering.

  • Avoid too much nitrogen (you’ll get leaves instead of cucumbers).

Pollination

  • Cucumbers have male and female flowers.

  • Bees are essential for good fruit set.

  • Avoid spraying during bloom time.

Disease Prevention

Marketmore varieties are bred for resistance to:

  • Powdery mildew

  • Downy mildew

  • Cucumber mosaic virus

Improve airflow, rotate crops yearly, and avoid overhead watering to reduce problems.

Harvesting

  • Ready in 60–70 days.

  • Pick at 6–8 inches long for best flavor.

  • Harvest frequently to keep plants producing.

  • Use pruners instead of pulling.

Heat Tips (Middle Tennessee Friendly)

  • Afternoon shade during extreme heat can reduce bitterness.

  • Bitter cucumbers often result from heat or uneven watering.

  • Keep watering consistent during July/August heat waves.

 

How to Grow Pickling Cucumbers

Pickling cucumbers are shorter, blockier variety bred for crisp texture and ideal pickle size. They’re fast-growing, productive, and perfect for summer preserving.

When to Plant

  • Plant after last frost.

  • Soil temp must be at least 65–70°F.

  • In Middle Tennessee: late April–May.

  • For continuous harvests, plant a new round every 2–3 weeks until July.

Sun & Soil

  • Full sun (6–8+ hours daily).

  • Loose, well-drained soil rich in compost.

  • Ideal pH: 6.0–7.0.

  • Raised beds work very well.

Planting

  • Space 4–6 inches apart.

  • Rows 3–4 feet apart

Trellis or Sprawl?

  • Can sprawl, but trellising improves airflow and reduces disease.

  • Keeps cucumbers straight and cleaner.

  • Great option for small gardens.

Watering

  • Need consistent moisture for crisp, non-bitter fruit.

  • Aim for 1–2 inches per week.

  • Water deeply at soil level.

  • Mulch heavily during Tennessee summer heat.

Uneven watering = bitter or misshapen cucumbers.

Feeding

  • Mix compost in before planting.

  • Side-dress with compost or balanced fertilizer at flowering.

  • Avoid high nitrogen (too many leaves, fewer cucumbers).

Pollination

  • Separate male and female flowers.

  • Bees are essential.

  • Avoid spraying during bloom.

Disease Prevention

Many modern pickling varieties resist:

  • Powdery mildew

  • Downy mildew

  • Cucumber mosaic virus

Tips:

  • Rotate crops yearly.

  • Don’t water leaves.

  • Harvest often.

Harvesting for Pickles

  • Ready in 50–60 days.

  • Pick at:

    • 2–3 inches for gherkins

    • 3–5 inches for standard pickles

  • Harvest daily during peak season.

  • Do not let fruits overgrow — plants slow down production.

Heat Tips (Middle Tennessee Friendly)

  • Afternoon shade during extreme heat helps.

  • Keep watering consistent in July/August.

  • Bitter cucumbers are usually from stress (heat or drought)

🥒 Pickle Harvesting Size Chart

Use this chart to pick cucumbers at the ideal size for different types of pickles. Harvest daily during peak season for best quality.

Pickle Type Cucumber Length Approx. Days After Flowering Best Use Texture Result
🥒 Gherkins 1–2 inches 3–5 days Whole sweet or dill pickles Very firm, crunchy
🥒 Baby Dills 2–3 inches 4–6 days Whole dill pickles Crisp, classic snap
🥒 Standard Dills 3–5 inches 5–8 days Whole or spears Firm with good crunch
🥒 Spears/Chips 4–6 inches 6–10 days Spears or sandwich slices Slightly softer but still crisp
⚠️ Overgrown 6+ inches 10+ days Relish (remove seeds) Softer, more seeds

Harvesting Tips

  • Pick in the morning for best crispness.

  • Use pruners or scissors — don’t pull.

  • Harvest before seeds enlarge.

  • Frequent picking encourages more production.

  • Store unwashed in the fridge and pickle within 24 hours for maximum crunch.

Heat & Quality Reminder (Middle Tennessee Friendly)

  • In hot weather, cucumbers size up quickly — check daily.

  • Uneven watering can cause bitterness.

  • Mulch to keep soil moisture consistent.

How to Grow Straight Eight Cucumbers

Straight Eight is a classic heirloom slicing cucumber variety known for its straight, dark-green 8-inch fruits and excellent fresh flavor.

When to Plant

  • Plant after all danger of frost.

  • Soil temperature should be 65–70°F minimum.

  • In Middle Tennessee: typically late April–May.

  • For a fall crop, sow again in late July.

Days to maturity: 55–65 days.

Sun & Soil

  • Full sun (6–8+ hours daily).

  • Rich, well-drained soil.

  • Mix in compost before planting.

  • Ideal pH: 6.0–7.0.

Cucumbers are heavy feeders — fertile soil makes a big difference.

Planting

  • Space 6–12 inches apart.

  • Rows 3–4 feet apart.

Trellis for Straighter Fruit

Straight Eight benefits greatly from trellising:

  • Keeps fruits straight and clean.

  • Improves airflow.

  • Reduces disease.

  • Makes harvesting easier.

If allowed to sprawl, give each plant plenty of space.

Watering

  • Provide 1–2 inches of water per week.

  • Keep soil evenly moist.

  • Mulch to prevent drying out.

  • Water at soil level (avoid wet leaves).

Inconsistent watering can cause bitterness or misshapen fruit.

Feeding

  • Compost at planting time.

  • Side-dress with compost or balanced fertilizer when vines begin flowering.

  • Avoid excess nitrogen (too many leaves, fewer cucumbers).

Pollination

  • Separate male and female flowers.

  • Bees are essential for fruit set.

  • Avoid spraying during bloom.

Disease Prevention

Straight Eight is an heirloom, so it has less disease resistance than some modern hybrids.
To reduce problems:

  • Rotate crops yearly.

  • Trellis for airflow.

  • Avoid overhead watering.

  • Remove diseased leaves promptly.

Harvesting

  • Pick at 7–8 inches long for best flavor.

  • Harvest frequently to keep vines producing.

  • Use pruners — don’t pull.

Letting fruit get too large slows down production.

Heat Tips for Tennessee

  • Afternoon shade can reduce bitterness in peak summer.

  • Heavy mulch helps maintain soil moisture.

  • Check daily during hot spells — cucumbers grow fast!

Companion Planting

Companion planting can help with pest control, pollination, and space efficiency.

Best Companions

  • Dill
    Attracts beneficial insects.

  • Nasturtium
    Repels cucumber beetles.

  • Radish
    Often planted to deter beetles.

  • Sunflower
    Can act as a natural trellis for vining types.

  • Bush bean
    Improves soil nitrogen.

Multi-Crop Companions (Work Well With Tomatoes and Peppers)

  • Calendula

  • Sweet alyssum

  • Chives

  • Parsley

These attract pollinators and beneficial insects like ladybugs and parasitic wasps.

Avoid Near Cucumbers

  • Aromatic herbs like sage

  • Potatoes

  • Melons too close (shared pests/diseases)

Common Pest What to Plant Nearby How It Helps
Cucumber beetles Radish, Nasturtium May deter; acts as trap crop
Aphids Sweet alyssum, Dill Brings in hoverflies & lacewings
Squash bugs Marigold Repels and confuses pests
Spider mites Parsley Attracts beneficial insects
