Marketmore Cucumber
Cucumis sativus 'Marketmore 76'
An old release that stays in catalogs because its disease package still holds up in a humid summer.

Why this one
Marketmore 76 carries resistance to scab, cucumber mosaic virus, and downy and powdery mildew. In a river-valley August that is the difference between a crop and a compost heap. It has stayed in catalogues since 1976 for exactly that reason, despite newer hybrids yielding more in easier climates.
Sow into warm soil
Cucumbers germinate fast at 65F and rot below it. Direct sow an inch deep after last frost, or start in peat pots two to three weeks early - they have brittle roots and hate bare-root transplanting.
Trellis it
Ground-run vines give you curved fruit, more rot, and a harder time spotting what is ready. Vertical growing also moves air through the canopy, which is most of mildew prevention, and it lets you plant twelve inches apart instead of three feet.
Feeding and water
Cucumbers are mostly water and need an inch and a half a week without interruption, especially once fruit sets. Rich soil with compost, plus a side-dressing when vines start to run. Drip or base watering, never overhead.
Bitterness
Bitter cucumbers come from stress - usually irregular water or heat - which raises cucurbitacin levels, concentrated at the stem end and just under the skin. Keep moisture even, mulch, and pick in the morning. If one is bitter, peel it and cut an inch off the stem end.
Pollination
Marketmore is monoecious, so it needs bees to move pollen from male to female flowers. The first flush of flowers is all male and drops - that is normal. Misshapen or stub-ended fruit means incomplete pollination.
Pests
Cucumber beetles are the serious problem, not for their chewing but because they transmit bacterial wilt, which collapses a vine irreversibly within days of the first wilting leaf. Row cover until flowering is the best defence. Squash bugs and aphids also occur; spider mites flare in hot dry spells.
Keep picking
One cucumber left to yellow on the vine tells the plant it is done. Harvest every day or two at eight to nine inches, cutting rather than pulling. In peak season a well-grown trellised plant produces daily.
Storage
About a week refrigerated, though cucumbers suffer chilling injury below 50F and are better in the warmest part of the fridge or a cool room. Do not store next to tomatoes, apples or bananas - the ethylene yellows them fast.
