How to Grow Cucumbers

As with all vegetables, homegrown Cucumbers taste so much better than those you can find at the grocery store. They're delicious and refreshing sliced on their own, in salads, sandwiches, or for the ambitious—Gazpacho. Given that they're so easy to grow, why not add them to your summer garden?

Care of Plants On Arrival

Your Cucumber plants have just spent up to three days without light or water and may have yellow leaves or show evidence of wilting. Through years of shipping experience, we have found that more than 98% of these plants will survive and thrive if you follow the simple care instructions below.

Please take your plants out of the shipping box as soon after their arrival as possible, taking care not to damage any stems or leaves as you free the plants from the cardboard packaging.

If the soil is dry, water gently but thoroughly from above or set the pot in a saucer of water for an hour or so -- just long enough for the soil in the pot to become thoroughly moist, but not soggy.

Place your plants in bright but indirect light indoors or, if temperatures permit, outdoors in the shade, sheltered from the wind. Don't put your plants in full sun right away because their leaves are tender after the trip and could be burned (sunscalded) or fall off if exposed to too much sun too soon. Allow your plants to adjust gradually over the next few days to increasing amounts of sunlight.

We've tried to time the shipping of our young Cucumber plants so that they arrive at or near the frost-free date in your climate zone. If, however, the weather is still raw and a frost seems likely, transplant your plants into larger pots, taking them outside during the day when the weather is mild and bringing them in whenever frost or blustery cold weather threatens. Young plants are more tender than mature plants, and even if the last spring frost is already past, near-freezing temperatures and cold spring winds are capable of killing your new plants. Expose your young plants to outdoor conditions gradually, giving them a chance to harden off before they're planted out. When the weather does settle and both days and nights become reliably mild (night-time temperatures should remain above 50°F), then it's time for planting out.

Planting Cucumbers Outdoors

Cucumbers like warm soil and hot, sunny conditions. When the weather is warm and settled, choose a planting location in full sun with rich, fertile soil and good drainage. To reduce soil-borne diseases, plant Cucumbers where you haven't grown them in the past 3 years. Dig a hole that will generously accommodate the plant's root ball, and mix compost or aged manure and a handful of low-nitrogen, organic fertilizer into the planting hole. If the weather is hot and sunny, plant in the cool of morning or wait until late afternoon to minimize stress. Recommended spacing between plants is indicated on the White Flower Farm label.

To remove a plant from its pot, flip the pot over, tap on its bottom, and slip the plant out. Do not pull the plant out by its stem. Loosen the root ball and tease the roots apart if they are matted or tangled. Set vegetable starts into their holes so that the tops of the root balls are level with or just slightly below the surrounding soil.

Push soil back into each planting hole and firm the soil around each plant to eliminate air pockets. Water thoroughly to further settle the soil. Keep the soil around the plants moist but not soggy and provide shade (with row cover, cardboard, or lath) for the first few days. Transplant shock is not uncommon, but within a week or less the plants' roots will regain their ability to provide moisture to the foliage. Remove shading once plants perk up. Provide vining varieties with a fence, cage, trellis or other support to climb on; bush varieties do not require a support.

Continuing Cucumber Plant Care

If rain is scarce, water your vegetable plants deeply and regularly (weekly, or more often in hot, dry weather).

Apply a layer of mulch to maintain moisture about 4 weeks after planting. Side-dress with compost or an all-purpose fertilizer when plants are about 6in tall and again when the first fruits begin to form.

Once plants start producing, check frequently for cukes so they won't get too large (harvest by cutting the stalk with scissors). Keep fruits picked to ensure continuous production.

 

Frequently Asked Questions

 

How tall do Cucumber plants grow?

The ultimate height of your Cucumber plant depends on the variety and whether it's growing on a trellis or other support. Otherwise, the vines will grow along the ground taking up a lot of horizontal space in the garden.

How to prune Cucumber plants?

Cucumber plants grow better with pruning. Cutting back the side shoots to only a few leaves when the plants are young directs all the growing energy to the main shoot. This allows for the production of bigger and healthier fruit.

When is the best time to plant Cucumbers?

The best time to plant Cucumbers is between April and June depending on your Growing Zone. Cucumbers need the warm temperatures of summer to grow and won't tolerate even a mild frost.

Can you grow Cucumber plants in a pot?

Yes, you can grow Cucumbers in a pot. Plant a compact variety in a large pot made out of a realatively impermeable material like lava or plastic that won't allow the soil to quickly dry out. Train the Cucumber plant to grow vertically on a support in or near the pot to take up less space.

How fast does a Cucumber plant grow?

Cucumbers mature 50-70 days from planting. Be sure not to leave them on the vine long past maturation (when they're 6-8" in length) or they may lose some of their fantastic tender sweetness.

Best Cucumber Companion Plants?

Prolific Cucumber plants are heavy feeders so it's helpful to pair them with other plants that impart the minerals they need into the soil, particularly Nitrogen. Good companions include Peas, Lettuce, Broccoli, Cabbage, and Cauliflower. Other possibilities include Corn to support vertical growth and Marigolds to repel pests.
