What temperature is too cold for cucumbers? A temperature of 32 degrees Fahrenheit (0 degrees Celsius) or below will result in frost, which will kill cucumber plants. Any temperature below 50 degrees Fahrenheit (10 degrees Celsius) will result in slower growth of cucumber plants, and will eventually damage them.
What conditions do cucumbers like?
You want them to be moist, not wet, so little and often is best. Feed your cucumber plants with a high nitrogen feed every two weeks. Cucumber plants like sun, but are prone to scorching, so some shade is preferable. Encourage greenhouse varieties to climb to boost yields.
Does cucumber plants need full sun?
Site selection. Although cucumbers do best in loose sandy loam soil, they can be grown in any well-drained soil. Cucumbers must be grown in full sunlight. Because their roots reach 36 to 48 inches deep, do not plant them where tree roots will rob them of water and nutrients.
How much sun do cucumber plants require?
Cucumbers will grow best when planted in full sun. Cucumber plants that do not get enough sunlight are more likely to have a poor fruit set and produce an overall lower yield. Therefore, it is best to plant them in areas that get at least 8 hours of direct sunlight each day.
Can cucumbers handle 40 degrees?
Cucumbers (Cucumis sativus) are tender annuals that thrive in warm temperatures of between 65-75 degrees F. (18-23 C.). Even prolonged exposure to temperatures below 55 degrees F. Sudden cold snaps can cause cucumber plant damage on leaves, stems, and fruit or even kill the plants.

How cold tolerant are cucumber plants?

Do cucumbers need lots of water?
The main care requirement for cucumbers is water—consistent watering! They need at least one inch of water per week (or more, if temperatures are sky-high). Put your finger in the soil and when it is dry past the first joint of your finger, it is time to water. Inconsistent watering leads to bitter-tasting fruit.

When can I plant my cucumbers outside?
Outdoor cucumbers should be planted out when the soil has warmed in late spring or early summer. Gradually acclimatize plants for a week or two beforehand. A cold frame is useful for this hardening off period. In warmer climates you can sow seeds straight into their final growing positions.
Can cucumbers be grown in pots?
Water-loving cucumbers do best in plastic or ceramic containers, whose material retains moisture. Pots need holes in their bottom for drainage, and size does matter. Ideal pots are a foot or more in depth, and that size will increase your harvest. A pot that's 20 inches wide can accommodate four to six plants.

Why do cucumbers turn yellow?
When cucumbers become over ripe, their green coloring produced from chlorophyll begins to fade, resulting in a yellowing pigment. Cucumbers become bitter with size and yellow cucumbers are generally not fit for consumption. A yellow cucumber can also be the result of a virus, too much water, or a nutrient imbalance.
Why are my cucumber seedlings wilting?
Plants will wilt if they're thirsty or waterlogged. Check the soil -- if the top 2 to 4 inches feel dry, the plant needs more water. Give about 1 inch of water so the soil feels moist, but not soggy. Wait for the soil to dry out before watering again.
