Water trees, shrubs, lawns, and perennials during prolonged dry fall and winter periods to prevent root damage that affects the health of the entire plant. Water only when air and soil temperatures are above 40 degrees F with no snow cover.
When To Stop Watering Plants in Fall. When the air and soil temperatures consistently fall below 40 F, it's time to stop watering. The ground can't absorb water once the top few inches freeze. Continue to water your plants up until this point so they're as well-hydrated as possible going into winter.
In fall, plants do not need as much water as they may have needed in summer. But rather than stop watering altogether, it's best to wean them from weekly watering to every other week to monthly throughout fall.
You can still expect some warm weather during October, so keep watering the garden until the fall and winter rains begin. As temperatures drop, less water is needed for plants. Check your soil periodically by digging gently into the soil next to the root, about 6 inches down (deeper for bigger plants).
Watering your trees is essential during dry periods in the fall, winter, and early spring, when you aren't watering your lawn.
Make sure to watch the temperature outside, you do not want to water your trees in temperatures under 40 degrees Fahrenheit, and there is no snow or ice near the tree. If the temperature is below freezing, not only will these cause issues with your sprinkler system, but they can cause damage to your tree's roots.
Water trees even when dormant. Water about 5 gallons per trunk diameter inch. Stop watering when the ground freezes or temperatures dip below freezing.
Water Wisely
Most lawns need to be watered no more than three days a week in the spring as well as in the summer and two days a week in the fall.
Q. How much water do plants need a day? Plants don't need daily watering. Instead, water deeply but less frequently.
In the spring and fall and in cooler climates, it might be sufficient to water container plants every two to three days. In the summer and in warm climates, container plants usually require daily watering, unless they are succulents or other drought-tolerant xeriscape plants.
Browning leaves are typically caused by under watering, sunburn, or overwatering. If the leaf tips are turning brown and crunchy, the soil likely became too dry for too long in between waterings. This can also cause the plant to drop leaves.
During really hot weather, water your vegetables at least two to three times a week. Watering the garden deeply is critical. The water must go down, down, down to encourage deep roots and get away from the hot soil surface.
Spring Perennial Plantings:
Week 1: Every day to every other day. Weeks 2-3: Water 2-3 times per week, depending on environmental conditions. Weeks 4+: Water 2-3 times per week, more in hot/dry conditions. When cooler, water less.
Water after rain.
Believe it or not the best time to water is after rain, when the ground has been softened and is more receptive. Extra water at this point tops up the rainfall, so it can penetrate further down into the soil. This is a great way to build up meaningful soil moisture.
It's important to cut back foliage in the fall to protect flowering plants from disease and give them a clean start for regrowth as winter starts to turn into spring. However, there are some plants you can keep around through the winter since they benefit wildlife and still offer visual interest for your home.
The best time to water is early in the morning when it's still cool, which preps the plants for a hot day, but that's not always easy to accomplish with a busy schedule. The second-best time is late in the afternoon or early evening.
The best time to water plants is in the morning or evening.
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.
The best way to tell if your plants need water is to stick your finger about an inch into the potting mix—if it feels dry, break out the watering can.
Allowing the soil to dry out in between waterings (while not stressing the plant) is really important for preventing disease, mold, and growing stronger and healthier plants. Less frequent but deeper watering is better than frequent shallow waterings (once plants are established).
To water or not to water? There is some discrepancy on whether or not you should water your lawn right after fertilizing. Our recommendation is to feel free to water in lightly without soaking your lawn, or simply wait until later in the week when you're expecting some rainfall.
Newly planted trees or shrubs require more frequent watering than established trees and shrubs. They should be watered at planting time and at these intervals: 1-2 weeks after planting, water daily. 3-12 weeks after planting, water every 2 to 3 days.
Despite the fact your plants are dormant and brown, they should still be watered periodically. Plants that remain dehydrated in winter months often don't survive until spring. Not only does this create extra landscaping costs in warmer months, it can actually damage your plumbing.
Watering should take place every day for approximately 15-20 minutes, depending on the pressure in your system. Of course, if it rains that day, no watering is necessary. It is best to water in the evening or early morning when the sun isn't up.
Although trees and shrubs are dormant during winter, they still need water to survive.
Following these tips will help you make the most of your time and water resources and keep your trees strong and healthy. Water in the early morning or evening. Watering during the hottest part of the day causes water to evaporate before it gets where it needs to go. Avoid wetting foliage when watering.
