Cucumber plants are a warm weather crop, and they are very sensitive to cold. Without protection, a frost will kill them. Cucumber seeds will not germinate in soil colder than 60 degrees Fahrenheit (15.6 degrees Celsius).
What is the lowest temperature cucumber seedlings can tolerate?
Temperatures below 55℉ (13℃) are too cold for cucumbers. Cucumber seeds won’t sprout in temperatures below 65℉ (18℃). Cucumbers growing in cold weather are susceptible to cold damage and death. If you attempt to grow cucumbers in cold weather, they may not flower or bear fruit.
When can I put cucumber seedlings 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.
What happens if cucumber plants get too cold?
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.
At what temp should you cover cucumber plants?
Cucumbers are very tender and can be killed by light frosts. Start cucumbers in the garden by planting seed or transplants. Cucumber (Cucumis sativus) is a warm-season vegetable that grows best at temperatures between 75 and 85 °F.

At what temperature should I cover my cucumbers?
What Is The Lowest Temperature Cucumber Plants Can Tolerate?
Temp Range | Effect |
---|---|
Below 50 F (10 C) | Slow growth of plant. |
Below 60 F (16 C) | Seeds do not germinate. |
Below 65 F (18 C) | Wait to transplant. |
65 to 75 F (18 to 24 C) | Transplant outdoors. |
What temperature do you transplant cucumber seedlings?
Cucumbers are very sensitive to cold. They need warm soil and air, whether direct-seeded or transplanted. Don’t rush to plant too early. Seed will not germinate if soil temperature is below 50 F, and germinates only slowly at 68 F.
Why are my cucumber seedlings so tall?
The most common cause of legginess is an insufficient or uneven access to light. When the light source is too dim or distant, seedlings grow quickly in height to get closer to that light. As the seedling gains height, it sacrifices in girth and strength, resulting in thin, pale, fragile, stretched-out stems.
Should you start cucumbers indoors?
Like other cucurbits, cucumbers don’t like to have their roots disturbed and can be tricky to transplant. However, if you want an early start on the season, it’s worth the risk to start a few cucumber plants indoors in peat pots about two or three weeks before setting out.
How do I protect my cucumbers from frost?
Seeds typically won’t germinate below 50°F (10°C). Frost may harm, or even destroy, cucumber crops. Cucumber plants can be protected using row covers, cloches, and planting in sheltered areas. It’s possible that temperatures even slightly above 50°F (10°C) may have little, or no, effect on your cucumber plants.
What do Overwatered cucumbers 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.
Why are my cucumber seedlings dying?
Cucumber plants need plenty of water, especially when it’s hot outside. Too much water, though, can kill your plant. 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.
What is killing my cucumber seedlings?
Bacterial wilt kills cucumber plants
This pathogen affects all members of the cucumber family, including cukes, muskmelons, pumpkins, and squash. The first sign of infection is wilted and drying leaves, sometimes seemingly overnight.
How big should cucumber plants be before transplanting?
Prepare the bed
Transplant cucumber seedlings at three to four weeks old and after your area’s last frost date, advises Missouri Botanical Garden. They should have two to four true leaves by that point. True leaves grow after the first two seed leaves emerge.
Can you bury leggy cucumber seedlings?
Can you bury leggy seedlings deeper in the soil? Generally, yes, you can plant leggy seedlings deeper in the soil to help compensate for the extra-long stems! However, avoid the temptation to plant them deeper right away, when they’re still very young and tender.
Do leggy seedlings recover?
What is this? The good news is, leggy seedlings can usually be fixed before it’s too late. I’ve transplanted hundreds of tall, floppy seedlings with success, most of which went on to recover and have normal, productive yields.
What is the best month to plant cucumber?
Cucumber seeds should be sown in a propagator between March and April. But you can get started in February if your greenhouse is heated, and in May to June if you plan to sow the seeds directly outdoors. Sow the cucumber seeds on their sides at a depth of 1cm in 7.5cm pots of free-draining, seed sowing compost.
Can I grow cucumbers indoors in winter?
To give your cucumbers plenty of sunlight indoors, you’ll either need a greenhouse that lets the sun shine in or supplemental lighting. Even if you have a glass walled greenhouse, your cucumbers might need supplemental lighting in the winter, when there’s less daylight.
How many cucumbers do you get from one plant?
Depending on who you ask, a healthy cucumber plant can be expected to produce 10 large cukes or 15 small ones within a harvest period of about three weeks.
How do I protect my seedlings from frost?
Cover Seedlings
Place cloches over young vines and veggies (such as tomatoes and peppers) in the spring to protect them from late frosts. If the temperatures are expected to hover around the freezing mark, cover long rows of seedlings lightly with loose straw or mulch to help the soil retain heat a bit longer.
Can you cover plants with a bucket to protect from frost?
–Buckets and plastic plant pots are great for covering tender plants. Simply turn the bucket or container upside down and place it over the plant. (It’s a good idea to put a rock or brick on top of the container to keep it in place.)
