Although the idea has been around for years, most plants don't need extra care by watering them at night. There are a few exceptions but 99% of your plants, indoors as well as outdoors, should be watered during the day.
4 Easy Ways to Water Plants
- Knowing When to Water Plants. A good rule of thumb when it comes to watering plants is to place your finger (or thumb) in the soil.
- Misting Method. Ferns particularly enjoy a good misting.
- Sink Bath Watering Method.
- Gradual Flow Devices.
- Double-Pot Watering Method.

The signs for an overwatered plant are:
- Lower leaves are yellow.
- Plant looks wilted.
- Roots will be rotting or stunted.
- No new growth.
- Young leaves will turn brown.
- Soil will appear green (which is algae)
Water before 9 a.m. in summer. As the day heats up, water can evaporate before your plants have a chance to soak it up. Water Deeply. Deep watering is most effective since it goes right to the roots.
The best time to water plants is in the morning or evening.Watering in the morning prepares the plant for the day to come and watering in the evening cools it off. More importantly, watering at these times actually helps the plant retain water.
When to waterThey 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. After 12 weeks, water weekly until roots are established.
Just take an old, cleaned out milk jug or water jug. Keep the lid, and poke 15 to 20 small holes through the lid with a large sewing needle or other small sharp object. Once you fill up the jug and screw on the lid, you will have an environmentally friendly and completely free watering can.
The big disadvantages to hand watering are the time required and inability to use a timer. Also, if someone is inexperienced, there is a good chance plants will either be over- or under-watered.
As for cooling your plants, it's true that wetting the foliage can reduce leaf temperature, which reduces evaporation and can help your plant conserve water. While it's not recommended as a daily habit, some gardeners head out on extremely hot, dry days to cool down particularly heat-sensitive or fragile plants.
A soaker hose allows water to seep through the hose along its entire length. A sprinkler hose combines the features of a soaker hose and a water sprinkler. There are small holes on the sprinkler that allow water to be sprayed along the entire length of the hose.
DON'T water from overhead. Depending on the size of the plant, the water may never actually hit the ground because the foliage may overshadow the plant's base. DO give lawns an inch of water per week during dry spells which, with a sprinkler, takes about 90 minutes to deliver to one area.
Many larger soaker hoses take water in at 1/2 GPM while smaller diameter hoses take in less water and use less per hour. If you set your spigot to release 1/2 a gallon of water per minute then that means you are using 30 gallons of water per hour.
For most plants, only water when the soil is dry — not just surface dry, but 2-inches-deep dry. Use your fingers to easily determine soil moisture levels.
No water is wasted.Sprinklers water the garden pathways just the same as the beds. With hand watering, the pathways remain dry. This suppresses pathway weeds – they will be less vigorous and provide less cover for slugs and insect pests. Although hand watering helps conserve water, it is not the most efficient method.
There is no hard-and-fast definition for watering deeply, but it generally means that the water is able to soak at least eight inches below the soil surface. The point behind this is that most plant's roots are not sitting close to the soil surface.
If your plant is becoming root bound, moisture might not soak into the soil and may run down the sides of the planter instead. Watering potted plants from the bottom eliminates these problems and adds moisture to the soil in a more efficient way.
Once planted, a tree needs the right amount of water to establish its roots and begin a long and healthy life. Too little water and the tree will wilt and die, but too much water can drown the roots and kill the tree just as easily. The best watering system for a newly planted tree is soaker or drip hose.
One inch is enough to give the plant what it needs at the moment, and allow the soil to hold a little in reserve until the next watering. That 1 inch includes rainwater as well as irrigation. Because container plants cannot pull water from deep in the soil like plants in the ground, they will typically need more.

This is a little more than 1 tablespoon per day. Water use was not constant during the study; small plants used 1 tablespoon per day, while large plants used slightly less than 2 tablespoons per day. Overall, there was a good correlation between plant growth and the amount of water applied.
One commonly used formula suggests 10 gallons of water per week for every 1 inch of tree caliper. For example: A single 2 inch caliper (trunk diameter) tree would require approximately 20 gallons of water per week.
