Pickling Cucumber Seed Planting Information:

Cucumbers don't do well if roots are disturbed, so it is best to plant seeds directly in the garden. Plant your seeds in soil, 2 to 3 weeks after last frost, when soil and air temperature is at least 60 F. Thin so there are 4 plants per hill. Cucumbers can also be grown in rows instead of hills, spacing 24" apart in rows 24 - 36" apart. Trellised plants can be grown as close as 10" apart. Cucumbers only take 55 to 65 days to maturity, so you can have multiple harvest by growing 2 to 3 weeks apart. Plants grow 1 ft tall and vines spread up to 6 ft.

Warning: Do not plant in cold wet soil or you may experience poor germination!

Soil Requirements:

Requires fertile soil in a well drained location in the garden. Apply much and grass clippings, or straw around base of plant.

Water Requirements:

The soil should be continuously moist. Water well during dry and hot spells. Make sure plants get ½" water per week.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Periodically apply Miracle Gro.

Harvest Tips:

Snip the stems with garden scissors when cucumbers are 2" long for pickling varieties. Harvesting frequently encourages more production. Pick daily to prevent fruit from becoming too large. Over ripe cucumbers will have a bitter taste.


A – Anthracnose

Scientific Name: Colletotrichum lagenarium

Type: Fungus

Anthracnose is a world-wide fungal disease that affects the growth of cucumbers, tomatoes, and watermelons. This disease is most common in the southern, mid-Atlantic, and mid-Western parts of the United States. Symptoms include lesions on the leaves and then yellowish circular spots begin appearing on the leaves. On watermelons the spots are irregular and turn dark brown or black. The most striking symptom is circular, black, sunken cankers appear on the fruit. When moisture is present, the black center of the lesion is covered with a gelatinous mass of salmon colored spores. With tomatoes, the disease mainly affects the tomato, but also can infect leaves, stems and roots. Sunken water soaked circular spots appear on the tomatoes. Leaves show symptoms of small circular spots with yellow halos. It can cause significant yield loss and even total crops losses. The diseased tomatoes are usually unmarketable. The infected plants should be removed to avoid further infestation. Increase space between the plants to maximize air flow and drying of the leaves. The disease is favorable when temperatures are 75-82 F and usually occur when moisture and humidity are very high. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in over winter on crop debris. Proper tillage practices may be helpful in managing the disease. Fungicides can help manage the disease. The best option is to use disease resistant varieties.

ALS – Alternaria Leaf Spot

Scientific Name: Alternaria brassicicola, Alternaria cucumerina, Alternaria dauci

Type: Fungus

Alternaria Leaf Spot, also known Alternaria Leaf Blight, is a world-wide fungal disease that affects the growth of broccoli, Brussels sprouts, cabbage, cantaloupes & melons, carrots, cauliflower, cucumbers, kale, kohlrabi, pumpkins, radishes, rutabaga, squash, tomatoes, turnips, and watermelons. Symptoms may first develop on young plants where leaf spots develop, plants become stunted, and damping off may occur. Greenish-brown lesions appear on the leaves, and turn from dark brown to black spots. The disease may appear on the leaves at any stage and start off as concentric circles and mature to lesions with a bulls eye appearance. The leaves curl, turn yellow, wither, and eventually die off, and heavy infestations may cause complete defoliation. The infected plants should be removed to avoid further infestation. Increase space between the plants to maximize air flow and drying of the leaves. The disease is favorable when temperatures are 75-82 F and usually occur when moisture and humidity are very high. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil for 8 years. Fungicides can help manage the disease. The best option is to use disease resistant varieties.

Ccu – Scab

Scientific Name: Cladosporium cucumerinum

Type: Fungus

Scab is a world-wide fungal disease that affects the growth of cantaloupes & melons, cucumbers, gourds, pumpkins, squash, and watermelons. Symptoms include pale green spots appear on the leaves which turn to gray spots and may have a yellow halo surrounding the lesion. The leaves become wrinkled and have ragged holes. The dead leaves crack and eventually fall off the plant. Cucumbers, pumpkins, and squash have sunken spots covered with greenish black velvety fungus. The fungus spores are spread by wind, insects, tools, and workers. The scab fungus overwinters on the seed, in crop debris, and in soil. The infected plants and vegetables should be removed, burned, or tilled in to avoid further infestation. The disease is favorable when temperatures are 59 - 77 F and usually occur when moisture and humidity are very high. Plan on using a 2 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in over winter on crop debris. Proper tillage practices may be helpful in managing the disease. Control weeds, by tilling. Fungicides can help manage the disease. Use drip irrigation instead of overhead sprinklers if possible. Keep the day temperature in the 80's and have proper air circulation in greenhouses. The best option is to use disease resistant varieties.

CMV – Cucumber Mosaic Virus

Type: Virus - Potyvirus

Cucumber Mosaic Virus is a world-wide virus disease that affects the growth of cantaloupes & melons, cucumbers, eggplants, gourds, peppers, pumpkins, spinach, squash, tomatoes, and watermelons. Symptoms include stunted or dwarfed plants, mottling, yellowing, distortion, and wrinkling of the leaves with the edges curling downward, and reduced growth rate and yields. The symptoms on leaves known as "shoestring" effect causes young leaves to appear narrow. The leaves will die and fall off, leaving part or most of the plant bare. The virus causes cucumbers to turn pale and gray, become bumpy and oddly shaped, and have a bitter taste. The virus causes peppers to have severe leaf damage with mosaic and necrotic rings. The peppers may have rings and spots. Tomato plants are usually stunted and have poorly shaped leaves and can cause partial or total crop loss. Plants infected with the virus have little or no marketable fruit. The virus can reduce yields and fruit quality. It is spread by aphids, seeds, and weeds. The virus overwinters in many perennial weeds. The infected plants should be removed to avoid further infestation. This virus cannot live in extremely dry conditions. The disease is favorable when temperatures are 79-89 F when aphid infestation is great. Symptoms usually begin to show in June. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Keep the fields weed free as infected perennials can harbor the virus. Proper tillage practices may be helpful in managing the disease. Insecticides for aphids are of limited value to control the disease. Spraying the tomato plants with mineral oil can delay the aphids from spreading the virus.The best option is to use disease resistant varieties.

DM – Downy Mildew

Scientific Name: Peronospora farinosa, Peronospora parasitica, Pseudoperonospora cubensis

Type: Fungus

Downy mildew is a fungal disease that affects the growth of beets, broccoli, cantaloupes & melons, cauliflower, cucumbers, spinach, Swiss chard, and watermelons. Downy Mildew is most serious for cucumbers, which can drop dead in a week and stop producing any fruit to harvest. The disease affects both seedlings and mature plants.The infected leaves are retarded in growth, turn yellow then brown, and turn downward. A white to gray color mold appears on the underside of the leaves. The leaves will wilt and eventually die. The disease can spread rapidly under favorable conditions and infect the entire field. The infected plants should be removed and burned to avoid further infestation. The disease is favorable when temperatures are 58-72 F and usually occur in early spring and autumn in cooler weather when moisture and humidity are very high. Fungicides can help manage the disease. Good air circulation and increasing space between the plants can help control and prevent the disease, so use wide plant spacing to promote drying of the leaves. The best option is to use disease resistant varieties.

ZYMV – Zucchini Yellow Mosaic Virus

Type: Virus - Potyvirus

Zucchini Yellow Mosaic Virus is a world-wide virus disease that affects the growth of cantaloupes & melons, cucumbers, gourds, pumpkins, squash, and watermelons. Symptoms include stunted or dwarfed plants, mottling, yellowing, distortion, blistering, and wrinkling of the leaves, and reduced growth rate and yields. The virus can cause total crop lose. The symptoms on leaves known as "shoestring" effect causes young leaves to appear narrow, and fern-like appearance of the leaves. The virus causes cucumbers to become bumpy and oddly shaped, and have a bitter taste. Cantaloupes & melons and watermelons are malformed and often develop deep cracks. Squash and pumpkins can develop knobby areas. Plants infected with the virus have little or no marketable fruit. The virus can reduce yields and fruit quality. It is spread by aphids and seeds. The infected plants should be removed to avoid further infestation. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Keep the fields weed free. Proper tillage practices may be helpful in managing the disease. Insecticides for aphids are of limited value to control the disease. Using transparent or silver plastic mulches have been shown to repel aphids and delay the virus from spreading. Ladybird beetles can be effective at naturally controlling aphid populations. The best option is to use disease resistant varieties.
