Plants that are drought-stressed often suffer more injury during freezes; however, watering does not actually provide any protection to tender plants. To protect plants with a covering of ice the spray of water must start just before freezing temperatures begin and continue constantly until they end.
Although tomato plants start out pint-sized, by autumn they can be absolutely massive – especially if they are of the indeterminate variety! To keep your tomato plants productive for as long into autumn as possible, they will need to be covered up each evening when temperatures dip below 50°F (10°C).
So, yes, it’s been cold at night around Southern California, but folks, 45 degrees is a still a long way from the freezing temps that can burn our tender tropicals and other plants, like a multiday cold snap in 2007 that severely damaged crops in Central and Southern California.
Times for planting might include late winter or early spring, when temperatures fall below 40 degrees at night in most parts of the country. … After hardening off the annual seedlings, you can plant hardy annuals if the temperature stays at 40 degrees or above.
Most pepper plants can only tolerate temperatures down to 32 degrees Fahrenheit (0 degrees Celsius) before they succumb to frost. Even at more mild temperatures of 55 degrees Fahrenheit (13 degrees Celsius), pepper plants will show slower growth.
Peppers do well in warm weather with 60-90 degrees Fahrenheit temperature. However, the plants will die if the temperature goes below the 32-degree Fahrenheit mark. It is important to consider factors like the variety, the place plant schedule, and other measures to protect your pepper plants from the cold.
You will need to bring your plants indoors before nighttime temperatures dip below 45 degrees (F). Most tropical plants will suffer damage at temperatures below 40 degrees, a few even below 50 degrees. Inspect plants for insects and diseases, and treat as appropriate before bringing plants back inside.

Although mature plants might survive light frosts, temperatures below 40 F damage flower and fruit production, making tomatoes perennial only in U.S. Department of Agriculture zones 12 and up. … Tomatoes flower and set fruit best when the air and soil temperatures range between 60 and 70 F.
According to Wikipedia the temperatures which will kill plants in hanging baskets are: slight frost: 0 to −3.5 °C (32.0 to 25.7 °F) moderate frost: −3.6 to −6.5 °C (25.6 to 20.3 °F) severe frost: −6.6 to −11.5 °C (20.2 to 11.3 °F)
Cool temperatures, with some moisture, that promote ice crystal development. … A local study done on frost formation relating temperature to dew point has these guidelines for frost: temperatures from 38 to 42 F can lead to patchy frost, 33 to 37 areas of frost, and 32 and below widespread frost/freeze.
