Cucumber

Before you plant this crisp, refreshing vegetable, consider how much space you can devote to growing cucumbers (Cucumis sativus) at home. The regular slicing varieties require about 15 square feet per plant. However, they can still be raised in smaller gardens by training vines onto a vertical trellis or wire fence. Cucumber plants may also be grown in containers and are very prolific.

Cucumbers are loaded with vitamin C and include many B vitamins. They also provide essential minerals like phosphorous, potassium, zinc, iron and magnesium.

Fun Fact: The term “cool as a cucumber” was first used in a poem by John Gay dated 1732: “I … cool as a cucumber could see the rest of womankind.”

Cool, refreshing heirloom cucumbers come in a variety of shapes and colors. Planting instructions are included with each ​seed ​packet and shipping is FREE!

Quick Guide: Planting, Growing & Harvesting Cucumbers

1. Plant after all danger of frost is gone, about 2-3 weeks after the last frost
2. Don’t plant too soon — cucumbers can only handle warm temps
3. To save space and keep fruit off the ground, grow vertically on fences or trellises
4. Water and fertilize regularly
5. Harvest in 55-70 days while skin is still tender
6. Pests and diseases include cucumber beetles and anthracnose

Site Preparation

Cucumbers require a planting site in full sun and even soil moisture. Mulch around plants to prevent soil from drying out between waterings. A straw mulch works best and will help keep them up and off the ground. Allow plenty of room for each plant, making sure that the soil is rich in organic matter and well drained.

How to Plant

Cucumbers need warm soil and do not tolerate frost. Wait for warm spring days and soil temperatures above 60˚F, usually about 2-3 weeks after the last frost date. It’s a good idea to start seeds indoors about 3 weeks before you plan to put them in the garden.

Keep trellised plants 6-10 inches apart. When planted in hills and allowed to run, grow three plants to a 2-foot-wide hill with the hills spaced 6 feet apart. Apply an organic vegetable fertilizer in early spring, then provide supplemental light feedings (side-dressings or foliar spray) monthly throughout the gardening season.

Tip: Are you looking for a quality organic fertilizer to use in your vegetable garden? If so, we recommend Neptune’s Harvest® Fish & Seaweed. Packed with vitamins, amino acids, enzymes and naturally-occurring growth hormones, it outperforms many chemical fertilizers with much higher NPK numbers. Give it a try — you’ll see why it’s our all-time favorite fertilizer!

Harvesting and Storage

Pick fruits as soon as they reach the size that you want, and pick carefully and often because cucumbers are difficult to spot among the leafy foliage. Keep a constant vigil so that they don’t become woody and tough. Harvest should occur 55 to 70 days after planting.

For best results storing cucumbers, wrap each one in dry paper towels, then place them all inside a plastic bag. Stick the entire batch (bag and all) in the produce drawer of your refrigerator. Voila!

Small fruits — 4 to 5 inches — are great for pickling and will extend the harvest for months to come. Remember, your pickles will only be as good as the “cukes” you use — fresh and firm is best!

Insect & Disease Problems

Use row covers to get plants off to an early start and to protect them from insect pests. Plant coreopsis as a companion plant to attract cucumber beetles away from your crop. If the leaves turn brown and eventually shrivel and die, suspect anthracnose. This persistent fungal disease attacks all parts of the plant above ground.

Seed Saving Instructions

Cucumbers will cross-pollinate so isolate 1/4 mile from similar plants. Fruits for seed should ripen past edible stage and begin to soften and turn yellow. Cut lengthwise, scoop out seeds, wash, clean and dry. Seeds are dry when they break instead of bending.
