How Much to Water Plants Outside

Having a beautiful garden or maintaining an outdoor plants collection can be a gratifying experience, but it can also be challenging when it comes to watering. Too little watering can cause plants stress, yellow leaves or damage, while too much of it can lead to root rot and fungal diseases. So, how much to water plants outside? Here are some guidelines to follow.

The Rule of Thumb

The most straightforward and slightly less adequate method to know if it's time to water outdoor plants is to use the "rule of thumb" approach. Stick your finger into the soil around the root zone of your plants, and if the top 2-4 inches (5-10 cm) of soil feel dry to the touch, it is time to water them. However, this is not the most accurate method and may not apply to all plant species.

Factors That Affect Watering Frequency

The watering frequency of outdoor plants is influenced by several factors such as the type of soil, the plant species, the weather conditions, and the time of the year. Plants that are grown in sandy soil will dry out faster than those grown in clay soil. Likewise, plants with shallow roots may require frequent watering than those with deeper roots. The heat and wind can also speed up the soil evaporation process, both factors that you need to account for when watering your outdoor plants.

Watering Techniques

In general, it is advisable to water outdoor plants deeply but less often, rather than frequent, light waterings. Deep watering encourages the plant roots to grow deeper into the soil and develop a stronger root system. Water should be applied at the base of the plant close to the soil level, as opposed to overhead watering methods, which can encourage fungal diseases. Use a watering can or a hose with a wand attachment to ensure precise and targeted watering.

Watering Tips

During the summer, it's best to water your outdoor plants in the early morning before the sun starts to blaze. This helps reduce water loss from evaporation and allows the plants to absorb the water thoroughly. Adding a layer of organic mulch around plants can also help retain soil moisture and reduce water loss. Avoid watering under extreme weather conditions like heavy rainfalls or strong winds and check to see if the plants show physical signs of over or under watering.

In Conclusion

Watering your outdoor plants can be challenging, but it's essential to make sure they thrive and stay healthy. Several factors affect how much water your plants need, so it's crucial to know your plant species and follow the proper watering techniques based on their requirements. Remember to water deeply, less often, and at the right time of the day, and you'll enjoy a beautiful and healthy outdoor plants ecosystem.
