How to Water Newly Planted Trees and Shrubs

Planting trees and shrubs is an excellent way to beautify your landscape, add value to your property, reduce energy costs, and provide shade and shelter for wildlife. However, it's not enough to just put them in the ground and leave them to fend for themselves. To ensure the health and vitality of your new plants, you need to water them properly. Here are some tips and guidelines for watering newly planted trees and shrubs.

Watering Frequency

The frequency of watering new trees and shrubs depends on several factors, such as the species, soil type, weather conditions, and site conditions. As a general rule, newly planted trees and shrubs should be watered deeply and thoroughly once a week for the first year after planting. However, if you live in a hot, dry, or windy climate, or if your soil is sandy or shallow, you may need to water more often. Conversely, if you live in a cool, moist, or shady area, or if your soil is heavy or deep, you may need to water less often.

Watering Method

The method of watering new trees and shrubs is also important. You don't want to waste water by sprinkling it on the leaves or flowers, which can promote diseases and pests. Instead, you want to water the roots, which are the most important part of the plant that absorbs water and nutrients. One effective way to water trees and shrubs is to use a soaker hose or drip irrigation system, which delivers water directly to the root zone and minimizes water loss due to evaporation and runoff. Another option is to use a watering can or hose with a gentle spray nozzle, which allows you to control the amount and direction of water flow and avoid overwatering or underwatering.

Watering Amount

The amount of water you give new trees and shrubs depends on their size, age, and root system. As a general rule, you want to provide enough water to moisten the entire root ball, which is the mass of soil and roots that surrounds the plant. You can check the soil moisture by inserting a finger or a moisture meter into the soil, or by observing the plant for signs of stress, such as wilting, yellowing, or dropping leaves. If the soil is dry, you should water thoroughly until the water penetrates the entire root zone, which is typically 6 to 12 inches deep for younger plants, and up to 24 inches deep for older plants with deep roots. However, you don't want to water too much, which can lead to root rot, fungal growth, or nutrient leaching. A good rule of thumb is to provide 1 to 2 inches of water per week, depending on the factors mentioned above.

Watering Timing

The timing of watering new trees and shrubs can also affect their growth and health. You want to water them in the morning or in the evening, when the evaporation rate is low and the temperatures are cooler. Avoid watering during the hottest part of the day, which can cause the water to evaporate before it reaches the roots and can also scorch the leaves. In addition, avoid watering at night, which can create a humid and stagnant environment that favors disease and pests.

Watering Maintenance

Finally, you want to maintain a consistent and appropriate watering schedule for your new trees and shrubs throughout the first year and beyond. Don't assume that once the roots are established, you can stop watering them. Trees and shrubs need water even after they have matured, especially during droughts or long spells of dry weather. However, you don't need to water them as often or as deeply as you did during the first year. You can also reduce the amount of watering if you mulch around the plants, which helps to retain moisture and regulate soil temperature.

In conclusion, watering newly planted trees and shrubs is a crucial aspect of their survival and growth. By following these tips and guidelines, you can ensure that your plants receive the right amount of water at the right time and in the right way. With proper watering, your trees and shrubs can thrive and enhance your landscape for years to come.
