How much cold can tomatoes tolerate in the fall weather? Covering tomatoes usually provides adequate protection from frost and light freezes. However, the foliage and fruit will likely suffer damage should the overnight temperature fall to 28 degrees F (-2.2 C) or below for several hours.
Another temperature to keep in mind: tomato plants will not survive in temperatures below 35 degrees Fahrenheit, and will not thrive at temperatures below 50 degrees. Gardeners can use a frost date calendar to note their region's average dates of last frost in spring and first frost in fall.
Yes, pinch or cut off the obviously frosted leaves and stems. Tomato plants will usually develop new branching stems and leaves if they are lightly nipped by frost. The cold will set them back a little but they should make up for lost time once the weather warms up. Good luck with your tomatoes!
You don't leave them outside at night unless it's a few weeks past their typical last frost date, and at least 10C at night. Also, since your tomatoes are greenhouse-grown, they need to be gradually hardened off.
Frost tender plants like tomatoes, peppers, cucumbers, beans, squash and melons cannot take a frost and need to be protected if a storm comes through. Today I want to share with you 3 low tech frost protection systems that you can create to protect your precious seedlings and transplants from a damaging frost.
It's sunny again… wait… ), but some vegetables won't be happy (and grow into incredibly prolific tomato producers - yes, I'm talking to you, tomato fanatics) if you don't protect them until night temperatures warm up consistently to 50 degrees and above.
So it may well be that you have to water your tomato plants several times a day or just once or twice a week. The only thing that really helps here is to observe carefully.

Keep plants protected with a row or plant cover, or garden blanket. Another option: burlap. Take caution with roses and stick to insulating only, as roses should not be covered. Remember, garden blankets are designed for short periods during overnight frosts and light freezes.
Below 63°F, cucumbers do not grow. In such conditions, plants sit in the soil and become susceptible to damages caused by pests in the soil. With that said, check soil temperatures and be sure they are above 63°F before planting cucumbers.
Hi Sylve, it is unlikely your plants will recover, tomatoes loathe frost.
If you're seeing a bit of red on those green tomatoes, picking them individually and bringing them inside may be the best chance for ripening tomatoes. Like many fruits, tomatoes continue to ripen once they've been picked.

However, if your tomatoes have reached their mature size—regardless of being green—they are worth harvesting before a frost. Keep in mind that completely green tomatoes usually do not ripen well indoors.
Most houseplants are native to tropical areas and will not tolerate freezing temperatures. Many indoor plants will see damage when temperatures drop to the mid to lower 40s°F and nearly all will die if exposed to below freezing temperatures.
Despite its convenience, there's one item you should stay away from to cover your plants. If you're looking for tips for protecting your plants from frost, avoid using garbage bags as plant covers. Trash bags are not the best protection against frost damage, primarily due to their material.

Thoroughly Water plants if it won't rain before the freezing temperatures arrive. It may sound illogical. However, the moist ground stays warmer than dry soil. Watering the night before the freeze will insulate the grass and plants' root structure and decrease the potential for cold injury.
Depending on where you live, you might want to expose your tomatoes to morning sunlight, to afternoon sunlight, or to a combination of the two. Morning sunlight provides high-intensity light without excessive heat, therefore you should consider morning exposure if you live in a region with a hot climate.
Try to plant tomatoes in a different spot every year, rotating through your garden space every three to four years. Planting them in the same place allows disease pathogens that are specific to tomatoes to build up in the soil. By moving them around in the garden each year, you can break up the disease cycle.
Soil that contains a lot of sand doesn't hold water well and dries quickly. Because of this, tomato plants growing in sandy soil may need to be watered more often, about every three or four days. Clay soil, on the other hand, holds water well. Plants growing in clay soil usually only need to be watered once a week.
Several inexpensive materials can be used to protect young tomato plants including old-fashioned glass cloches, milk jugs and soda bottles.
I pour the bags out over a sifter, so 100 percent of what was growing underground remains intact and the soil can be saved and reused.
Place cardboard boxes, large trash cans, or plastic tubs over outdoor plants. Be sure to cover the plants all the way to the ground. The warmth from the soil is what keeps the plant warm, since the soil takes longer to freeze.
