Cucumber Plant Minimum Temperature

Bottom heating will be required for good germination in winter. Vegetable seeds and seedlings require minimum soil temperatures to germinate and grow.

Why Are Greenhouse Cucumbers Wilting And Dying Greenhouse Growing

The optimum daily average air temperature is 15-24C 65-75F.

Cucumber plant minimum temperature. Set the plants 90cm 3ft apart along the bed and thoroughly firm and water them in afterwards. The cucumber seedling shown above is exactly two weeks after sowing the seeds indoors. Cucumber plants thrive in warm moist soil with a pH of around six to 65.

Low temperatures give slow and uneven germination and plants of poor vigour. A few things to keep in mind. Ideally the bed temperature should be between 18-21C65-70F and the cucumbers planted with 1 to 2cm ½ to 1in of the rootball protruding above the surface in order to encourage water to drain away from the stem base.

Ideally soil temperature should be over 68 degrees F. Soil temperature triggers not only seed germination but is an important factor in soil chemistry. Try to maintain a minimum temperature of 15C Keep the compost moist but not wet Keep them out of direct sunlight cucumber seedlings can be prone to scorching Try to avoid disturbing the roots when you transplant them.

Daytime air temperatures should be maintained between 75 and 80 F but should not exceed 85 to 90 F. Cucumbers are generally speaking a high-light crop. The warmer the soil the faster the seeds sprout.

Seeds and seedlings require optimal soil temperatures to thrive. Temperatures during the night should not drop below 65 F. Cucumber plants wont grow well in heavy soil.

A temperature of 15C 60F is necessary for the ordinary varieties and 21C 70F for the All Female types. A temperature of 39 F will not kill your cucumber plants but if you have seeds planted and the soil temperature is in that range they may not germinate. Recommended air temperatures for cucumber cropping A minimum root temperature of 19C is required but 22-23C is preferable.

When growing cucumbers start seeds indoors under lights 3-4 weeks before your last frost date or buy seedlings from your local nursery. Most of the time the sudden fluctuation in temperature rather than cold air causes wilting and dying of cucumber plants in a greenhouse. 3-4 weeks after your last expected frost date is usually a suitable time to plant seeds outdoors.

Cucumber seed should be sown singly either in 75cm 3in pots or spaced 25cm 1in apart in boxes or pans. The optimum temperature for germination of cucumber seed is 27 C day and night. Cucumbers are cold-sensitive plants so the temperature after planting out should be no lower than 55 60F.

The ideal or optimal soil temperature for planting and growing most vegetables is 65 to 75F. Michigan State University Extension reports that the seeds germinate in three to 10 days in soil temperatures of 60 to 105 degrees. Avoid placing the seedlings in direct sunshine because this may well damage their delicate foliage.

Optimum temperatures for growth are at night about 18C and during the day about 28C accompanied by high light intensity. In either case dont set them out until daytime temperatures are in the 70s 21-27 C and nighttime lows in the 60s 15-21 C. Seed costs are high and growers may prefer to purchase plants from a commercial nursery costing about 50 to 85 cents each.

You can begin to grow cucumbers as soon as the soil is consistently above 70F21C which is close to the minimum temperature for germination. Cucumber seeds germinate best in a warm evenly moist location. The seedlings will sprout above the surface after about 8 days and at this stage place the pots in a light position with a minimum temperature of 15C 60F.

At approximately 90F32C cucumbers will. After germination optimal outdoor growing temperatures are between 65 and 75 degrees Fahrenheit -- ideally above 60 degrees Fahrenheit at night. Over 70 degrees F is better for germination if you are growing from seed.

Cucumbers are a warm weather vegetable and they will not grow well if subjected to those kind of overnight temperatures.
