General Watering Timeline: If you haven't received precipitation in winter, it's crucial to water your plants. With dry weather, once a month winter watering is suggested. If the dry weather continues, you may need to go to twice-monthly watering.
“Most plants will typically be fine if you're gone a week, but some may start to suffer if they go without water for two weeks,” says Justin Hancock, Costa Farms horticulturist.
💧 Should You Water Plants in Winter? 💧 Yes! Even in winter, outdoor plants need occasional deep watering, especially if it's been dry for several weeks. Evergreens benefit from a drink on warmer days to help them through the colder months. 🌱
If your soil is dry 12 hours after watering, you may need to water your garden twice a day. If it's drying out within 24 hours, you'll need to water every day while conditions stay the same. If it's still moist after 24 hours, you can wait a day or two to water again.
Over-watered plants are likely to get root diseases, primarily root rot. You probably won't know your plant has gotten root rot until you notice that it is wilted, but the soil is still wet. What exactly is root rot? There are several different fungi that cause root rot.

Flowers also need a steady flow of moisture right up until the ground freezes in late autumn. Wind down the water as temperatures begin to drop below 40 degrees. Most summer annual plants will freeze and die with the first or second hard frost.
The root of the trick's protection is a concept called "latent heat of fusion." When the water on the plant starts to freeze, it releases heat (a necessary process to turn water into ice), and that heat helps protect the plant.
You likely will not need to water much unless you're in a severe drought with no measurable precipitation for a month or more, he adds. During periods of drought, give your water a 1/2 inch of water every two weeks. You can check soil moisture by inserting a screwdriver or using a soil moisture meter.
If it's bone-dry, crinkled, and brown, the plant may not come back, though it's sometimes possible to get some regrowth from the base. However, if the plant is just drooping and needs water, it often recovers after being watered. Certain plants, like peace lilies, are known for bouncing back even after severe wilting.
A basic self-watering system can be constructed using little more than a water bottle. All you need to do is cut the bottom off the bottle and poke a hole in the bottle cap using a skewer. Then, simply add the inverted bottle to a normal pot or planter.
If the ground is too dry when winter frost hits, the cold can penetrate deeper into the soil and damage the root system. Keeping your soil moist before the ground freezes helps insulate those delicate roots, giving them a much better shot at surviving.
It is never too late in a plant's life to start misting in place of traditionally watering. Watering your plants is essential, and using a method like misting is a great way to keep that moisture level up without worrying about putting too much onto your plants and potentially damaging them.
Throughout the winter your plant is still going to need some water. If the soil gets completely dry, the plant can die of desiccation. While regular watering isn't necessary, monitor the moisture level and water if the soil is dry.
Drought-stressed plants are more prone to cold damage; plants that are really stressed in general are even more susceptible to damage from cold. Watering just before a freeze helps the plant by creating warmth.
Chlorine and fluoride
Chlorine added to drinking water does not harm most plants but some may develop brown leaf tips over an extended period of use. If desired, to remove chlorine from tap water let it sit in an open-top bucket for 24 hours to allow the chlorine to evaporate before using it to water plants.
By covering plants with clear tarps, gardeners can trap warmth around the soil and plant, keeping them shielded from frost. This technique is particularly useful for extending the life of herbs, leafy greens, and other hardy vegetables that thrive in cooler weather but require frost protection.
The best time to water outdoor plants is in the morning when temperatures are usually cooler. This gives the plants time to absorb the water so they can get through a long, hot day. The second-best time is late in the afternoon or early in the evening. Try not to water at night.
There is no universal temperature for all plants that is too cold, so that is why it is important to do your research. However, it is safe to say if living in an environment with harsh winters and temperatures below 20°F, it is always wise to bring plants indoors during this time, if possible.
Provide Slow, Deep Watering
If you are unsure how long to water new plants, aim for 30-60 seconds for small plants – longer for larger plants while moving the hose to a few locations around the plant. Avoid watering when the soil feels moist. The earth must be allowed to dry out between watering.
In cold weather, water should be trickled slowly into the soil. Water only when air temperatures are above 40 degrees F. Apply water at mid-day so there is time to soak in before possible freezing at night.
Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.
Overwatering, in simple terms, drowns your plant. Healthy soil allows for oxygen to exist in the space between particles of soil. If there is too much water or the soil is constantly wet, there is not enough air pockets. This results in a limited oxygen supply and plants are not able to breathe.
