How to Grow Cucumbers

Growing cucumbers ranks up with tomatoes when it comes to favourite vegetables to grow at home. And since growing cucumbers is so easy, no home garden (container or in-ground) should be without a vine or two. The plants are easy to grow, and a couple of vines will keep a family eating fresh cucumbers all summer. Use these planting and growing tips to successfully grow your own crop from seeds.

Planting Location

Cucumbers prefer full sun and well-draining soil. They are heavy feeders and require constant soil moisture, so a location near a water source will make tending to them easier on you. Bear in mind when selecting a planting location (and containers) that most varieties of cucumbers grow on vines, and those vines will need to be supported.

Soil Preparation

For in-ground planting, add four inches of compost or well-rotted cow manure to garden soil and till to the depth of 6 inches, then lightly rake until soil level. When planting cucumbers into containers, start with a good quality potting soil mix, then add two cups of compost and one-fourth cup of slow-release, granulated fertilizer and mix well. Use a balanced fertilizer, like 10-10-10.
Water the prepared soil well and allow to sit overnight before planting seeds.

Sowing the Seeds

Growing cucumbers from seed are very easy. The seeds can be started indoors in small containers of potting soil six weeks before the last predicted frost date. However, cucumber seeds germinate very quickly in warm soil, and the vines grow rapidly, so starting seeds indoor weeks ahead of planting time offers only a few days head-start for the first ripe cucumber.

Wait until the temperatures have been above 75 for three consecutive days, and all danger of frost has passed before planting seeds. Form a soil hill 12 inches in diameter and 6 inches high for each plant desired. Space the soil hills 12 inches apart in an in-ground garden or use containers that are at least 12 inches wide. Poke a finger into the center of the soil hill to create a half-inch deep hole. Drop two cucumber seeds into the hole, fill the hole with compost, but do not press or firm soil. Gently water and keep seed hills moist, but not soggy, at all times.

When planting more than one hill of seeds, plant at two-week intervals so you’ll have fresh cucumbers all summer.

After Care

After the seeds have germinated and grown into six-inch tall plants (it’s okay if both seeds germinate, the prepared soil can feed two vines), it’s time to add mulch and a trellis. Add two inches of organic mulch, like hay or wood bark, to each hill, covering the entire soil surface. The mulch will prevent weed growth and retain soil moisture. Water vines frequently throughout the summer and feed the vines with a water-soluble fertilizer once a month.

Install the support system at this time too. Cucumber vines produce tendrils and will attach themselves to whatever vertical trellis material you use. You can use almost anything to make a trellis, like wooden sticks, metal stakes, fencing, etc., as long as it’s sturdy enough to support the vine and developing cucumbers.

When to Harvest Cucumbers

Cucumbers begin to form on the vines in six weeks. Watch them closely after the first tiny cucumbers appear, they grow into full-sized cucumber overnight—harvest cucumbers between 2 – 6 inches long for the best flavour and smallest seeds.

Companion Plants

Cucumbers do their best when planted near beetscarrots, radishes, beans and peas. Never plant them near potatoes or sage; it will reduce cucumber production.

Seed Selections

When growing cucumbers, it’s important to note the several different varieties to know which variety is best for your garden, think about the amount of available growing space and how you plan to eat the cucumbers. The bush growing variety will grow on small compact bushes, take up little space and will only need a short support system. Vine growing varieties will reach about six feet in length and need a strong support system to keep the cucumbers off the ground.
