Protecting Cucumbers from Cold Even prolonged exposure to temperatures below 55 degrees F. (13 C.) can cause decay, pitting and water soaked areas on fruit. Sudden cold snaps can cause cucumber plant damage on leaves, stems, and fruit or even kill the plants.
What temperature can cucumber plants withstand?
Cucumber plants only tolerate temperatures down to 55℉ (13℃) before their growth starts to falter. On top of that, cucumber seeds will only germinate when soil temperatures are above 65℉ (18℃). Because cucumbers are not cold-tolerant, it’s important to protect them from cold weather and frost.
What temperature is too high for cucumbers?
Ideal temperature range for growth and fruiting is about 65° to 75°F. Most cucumber varieties tolerate warmer temperatures up to 90°F for short periods of up to a few days at a time, but growth and fruiting may be diminished at temperatures above 85°F.
Is it normal for cucumber plants to wilt in the heat?
If you notice your cucumbers wilting during a heat wave, then they may be getting too hot. You’ll likely notice an improvement directly after you water them, and at night, when the temperatures cool off. Give your cucumbers some shade during the hottest part of the afternoon if you can.
Can cucumbers handle frost?
In general, a frost (31-33 degrees F.) will kill beans, cantaloupe, corn, cucumbers, eggplant, okra, peas, pepper, potatoes, sweet potatoes, squash, tomatoes, and watermelon.
When should I cover my cucumbers at night?
Grow the fruit along fences, boulders, or shrubs to provide them with some protection from the cold. If a sudden cold snap is forecast, cover the cucumbers. The plants can be covered with whatever you have on hand, old bed sheets, plastic, newspaper, or other light material.
Can cucumber plants get too much sun?
Too much sun can also harm established cucumber plants, but in a different way. Instead of scorching the leaves, intense sunlight is more likely to damage the fruit on established cucumber plants. The leaves of cucumber plants protect the fruit from sunlight and prevent premature ripening.
Can cucumbers handle full sun?
Cucumbers grow best in full sun but will grow with just 5 hours of sun a day. Cucumbers are very tender vegetables; they need temperatures of 70°F (21ºC) or warmer to grow well.
Should I water my cucumber plants everyday?
Cucumbers perform best with regular, deep watering once a week or so and with more frequency if the weather is very hot for a period of days. Inadequate or inconsistent moisture can cause oddly shaped or poor-tasting fruit.
Should I remove wilted cucumber leaves?
Prune outside branches, leaves, flowers, and fruit as needed throughout the growing season. Begin trimming cucumber vines by removing any dead or damaged portions. Remove older leaves to allow light to reach developing fruit and improve air circulation. Trim off all shoots that branch from the main vine stem.
What does an overwatered cucumber plant look like?
Leaf yellowing is a common sign of overwatering. When roots are sitting in water, they become damaged and unable to absorb nutrients. When leaves are yellow from overwatering, they will often be stunted and limp and may fall off. When this happens, check drainage around the base of the cucumber and reduce watering.
What is eating my cucumber plants at night?

Why are the leaves on my cucumber plant turning yellow?
The most common reason for yellowing leaves is that you have a watering problem. That means you’re either giving your plant too much or too little water. Another reason could be nutrient deficiency.
Do cucumbers like shade or sun?
full sunlight
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 long does a cucumber plant live?
Considerations. Cucumbers are grown as an annual, which means that the plant does not regenerate after the growing season. Once it has lived out its life span of roughly 70 days, the plant dies and cannot be regrown.
Why do my cucumber plants wilt during the day?
Soil saturated with water will cause a plant to wilt because of the lack of oxygen in the soil. If the cucumber plant wilts only during the day and recovers at night, then the soil may be too dry.
Should I mist cucumber plants?
How to care for cucumbers. In the greenhouse, water cucumber plants regularly and mulch the soil to retain moisture and keep the area around them weed-free. Increase humidity by damping down the greenhouse regularly, or spraying the cucumber plants with a fine mist from your hose.
Do cucumbers need lots of water?

What grows well with cucumbers?
CARROTS, PARSNIPS, RADISHES and ONIONS are good choices for cucumber companion planting as they do not encroach on each other’s territory. The root vegetables primarily grow beneath the soil, whereas cucumbers send down one larger tap root and also a few shallow roots that don’t extend far.
How much water does a cucumber plant need per day?
