Marketmore Select Organic Cucumber Seeds

Harvest these cukes at about 8 to 9 inches long. They're perfect for fresh slicing, thanks to their smooth, straight growth and thin, dark green skin. You'll get good yields, too, because Marketmore Select is resistant to Scab, Cucumber Mosaic Virus, and both Downy and Powdery Mildew. Unbeatable for flavor, appearance, and quality!

Direct-sow seeds in a sunny spot after all danger of frost is past, or start indoors and transplant when the first true leaf appears. Cucumbers can be allowed to grow on the ground, but for longer, straighter fruit and to save garden space, grow them in a cage or on a trellis, allowing 1 foot between plants. Keep them well-watered, and keep the fruits picked promptly. Pkt is 20 seeds.

You'll find new meaning in the term "cool as a Cucumber" when you discover the delights of this delicious, easy-to-grow vegetable! Slice 'em, dice 'em, pickle 'em, or pull 'em straight off the vine and enjoy their unmistakable and delicious flavor right there. They can be grown on hills, in rows, on trellises, or in containers, so there's a variety just perfect for you, no matter where you live or how large or small your gardening space.

Choosing a Cucumber Variety

When you choose which Cucumbers to grow, you'll want to consider length, thickness, use, and the amount of space required for the plant. They come in a wide variety of sizes, from tiny Gherkin-appropriate ones to long, delicious slicers. The pickling types are usually smaller, and some of the slicers are burpless (less bitter and contain less burp-causing compounds).

There are several compact varieties just right for those with limited gardening space, and of course, you'll also be able to pick from various shades of green cukes, with some white and yellow types thrown in the mix!

When to Start Cucumber Seeds

Cucumbers are best direct sown outdoors 1 to 2 weeks after all danger of frost has passed in the spring and once the soil has warmed -- it needs to be at least 60 degrees F. They can be sown indoors (at a temperature of 70 degrees F) 4 to 6 weeks before planting out, but direct sowing is recommended.

How to Start Cucumber Seeds

Sow the seeds at a depth of 4 times the size of the seed, siting them in full sun in light, rich, well-drained soil. Fertilize before planting and then again every 3 weeks until you harvest. It's very important to keep the plants weeded and well watered. Be sure to disturb the roots as little as possible when weeding.

If you're growing your Cucumbers on hills, plant 4 or 5 seeds per hill, spacing them 4 to 5 feet apart. If instead you choose to plant in rows, space them 2 to 3 feet apart in rows that are about 5 to 6 feet apart. You can also grow them on a trellis, an option especially appealing if you have limited space. Expect germination in 7 to 10 days and harvests in 50 to 70 days.

Special Considerations

• If your Cucumbers become too large (hard and seedy) they will sap the strength away from the plant that would otherwise be used to grow more fruit. Just throw away any that become too large.
  
• Take care not to over-fertilize with nitrogen, as this can increase growth of the vine but decrease the amount of fruiting.
  
• Standard varieties of Cucumbers need more fertilizer than do bush, dwarf, and short-vined types.
  
• Cucumber vines produce both male (staminate) and female (pistillate) flowers. The first to arrive are male and will drop from the vine without bearing fruit. The ones to follow will be both male and female, allowing for pollination. So don't become discouraged when the first flowers you see don't produce fruit.
  
• There are also Cucumbers available that bear only female flowers (gynoecious). These varieties will include in the seed packet specifically marked seeds of a pollinator that must be planted as well in order for proper pollination to take place.

Growing Tips for Cucumbers

• If you want to start your seeds indoors, use peat pots or pellets -- something that can be planted as-is, thus minimizing root disturbance. Transplanting shouldn't be done until all danger of frost has passed.
  
• Cucumbers need long, warm, sunny days and mild nights in order to be productive.
  
• Keep well watered and fed throughout the growing season.
  
• Mulches, including black plastic varieties, can be useful in conserving moisture, preventing the soil from becoming compacted and the fruit from rotting, and in minimizing the presence of weeds.
  
• Harvest your Cucumbers depending on their use, and therefore their size. They can over mature (and become bitter) rather quickly since they develop so rapidly after pollination, so check your crop frequently in order to pick them at their peak quality.
  
• Be careful not to trample the vines any more than necessary while harvesting, and cut the stems about ¼ inch above the fruit.

Pests and Problems to Watch For

Powdery mildew:

• Plant mildew-resistant varieties whenever you can.
• If you can avoid it, don't apply nitrogen fertilizers late in the season. This will limit the production of succulent tissue, which is the most susceptible to infection.
• Avoid overhead watering.
• Remove and destroy infected plants -- DO NOT compost them!
• Allow for as much air circulation as you can.

• Choose pest-resistant varieties when possible.
• Early detection is very important, so look over your plants often.
• If only a few of your plants are infected, you can just collect and destroy the bugs and their egg masses. Boards, shingles, or something similar can be placed on the ground near the plants -- the bugs will often concentrate themselves to that area.
• You can cover the vines until blossoming begins, at which time they'll have to be uncovered for pollination.
• Burn or compost plant debris at the end of the season.
• Chemical insecticides can be used if nothing else works. Follow all label directions and safety precautions.

Cucumber beetles:

• Choose pest-resistant varieties if possible.
• Plow early to remove vegetation and discourage egg laying.
• Sandy soils aren't usually as susceptible to pest problems.
• Row covers can keep them off until the plants are well established.
• You can apply a foliar insecticide at the cotyledon stage (the appearance of the first leaves). Be sure to follow label instructions and safety precautions.

• Best sown outdoors
• Sow 1-2 weeks after danger of frost is past
• Seeds can also be sown indoors, 4-6 weeks before planting out, at a temperature of 70°
• Sow in individual pots to avoid root disturbance when transplanting
• Indoors and out, sow at a depth of 4 times the size of the seed and expect germination in 7-10 days

This prostrate or climbing vine grows approximately 8 feet long, but there are also bush varieties that don’t require support. They produce 1 inch, yellow flowers that are followed by the edible fruit. Harvest when they are dark green, before they turn yellow. The slicing types will be 6-8 inches long, while the pickling types will be 11/2- 3 inches long. Gently cut them off the vine; do not break them off. Cucumbers are eaten fresh; the pickling types are preserved with pickling spices and then canned

Superior Germination Through Superior Science

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Hand Packed By Experienced Technicians

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

The Park Seed Gold Standard

Heirloom Seeds are open-pollinated -- they are not hybrids. You can gather and save heirloom seed from year to year and they will grow true to type every year, so they can be passed down through generations. To be considered an heirloom, a variety would have to be at least from the 1940's and 3 generations old (many varieties are much older -- some 100 years or more!).

Hybrid seed are the product of cross-pollination between 2 different parent plants, resulting in a new plant/seed that is different from the parents. Unlike Heirloom seed, hybrid seed need to be re-purchased new every year (and not saved). They usually will not grow true to type if you save them, but will revert to one of the parents they were crossed with and most likely look/taste different in some way.
