If you have a complicated indoor garden or just want to get the most out of your plants, and you may think that watering at night will make them grow better. 

You might even find conflicting information on the Internet, and it can create a lot of confusion especially if you have just started gardening. Some sites claim that watering at night is bad for plants and others claim that it’s better than watering in the day.

The truth is that watering at night can be beneficial for certain types of plants, and is also dependent on where you live. So, in this post, we will discuss night watering in detail.

Pros And Cons Of Watering Plants At Night:

Why You Should Water Your Plants At Night: [Pros]

There are pros and cons to watering your plants at night. Here are just a few of the benefits to watering at night:

Ease of Care:

The most obvious reason is that it is easier to water plants at night. You don’t have to wake up early, it saves time, energy, and money.

Many gardeners find that watering their plants right before they go to bed is actually beneficial because it allows them to relax after a long day and makes the watering more of a routine than something they need to do right now.

Less Evaporation:

When you water your plants in the day, some of that water will evaporate as soon as it hits the soil surface. This occurs because daytime temperatures are often higher than nighttime temperatures.

Conversely, when you water your plants at night, the moisture remains in the soil as nighttime temperatures are typically far cooler than daytime.

Cons Of Watering Plants At Night:

But before you start putting your night gardening shoes on remember there are some drawbacks also. here are some important things you need to consider:

Wet Foliage:

The most common issue with night watering is wet foliage. Watering in the night can cause leaves to be wet for a longer period of time than if you were to water them during the day.

Wet foliage can attract bacteria, pests, such as fungus gnats, spider mites, and many other insects. If they lay eggs on your plant’s leaves while they’re still damp, those eggs will survive until conditions are right for hatching.

This could mean an infestation in a matter of days if you don’t notice the pests immediately and treat them accordingly.

Plant Activity:

Plants are more active during the day, the stomata will open during the day and release water. So the plant will need a lot of moisture during the day.

If there is no water available for this process it can cause stress on the plant and actually cause it to lose leaves or even die.

Waterlogging:

It’s easier for water to accumulate around the base of plants when you water them at night, which may lead to overwatering.

It causes the roots to sit in water for too long which leads to anaerobic conditions (a lack of oxygen). if this continues for a long time it will cause root rot and eventual plant death.

Frozen Water:

Another disadvantage is that because the water temperature is cooler at night, frozen water may build up in the ground around your plants’ roots as temperatures drop overnight.

This artificial frost will damage the roots of your plants, which can lead to death or drought stress.

Is Watering Plants At Night Is Always Bad?

Watering at night isn’t necessarily bad (although there are a few instances when you shouldn’t do it), but it does make sense that plants would be better able to “breathe” during the day than at night. 

Watering at night typically means watering when the air is still and humid, so many of the pores on a plant’s leaves will be closed, which prevents water from evaporating out as quickly. 

Of course, there are a few occasions when you might want to consider watering your plants at night — namely, during dry spells when you want to encourage deep root growth or if you’re expecting rain soon but still need to get in one evening of watering.

Watering gardens during dry spells can help relieve stress on outdoor plants caused by extreme weather conditions like droughts and heatwaves. Since evaporation happens more slowly with cool temperatures, you’ll have less risk of overwatering.

Watering Plants At Night:

If you’re planning on watering your garden at night, please follow a few simple guidelines so your garden doesn’t end up in a mess:

First, use a soaker hose or drip irrigation system. You don’t want to water your plants with sprinklers and create a muddy mess in the backyard.

Second, avoid watering the leaves of your plants. Watering from above can cause diseases and fungus to grow on leaves and stems. A better trick is to start at the base of the plant and water upwards.

Third, don’t overwater! The top 3 inches of soil should be moist enough for most plants but if you’re going to water at night, check it again in the morning for any dried-out spots. 

The amount of water that a plant need varies based on what stage it is in its growth cycle. Young plants that are actively growing need more water than mature ones.

Flowers and fruits need a lot of water. So plants that are blooming or fruiting will need more water than those that aren’t.

Do Plants Absorb Water At Night?

You may think that watering plants at night is a waste of time, but studies show that plants actually absorb water better at night.

It’s true that they don’t require as much water to survive as we assume, but they do need some water absorbed into their roots to keep them moist and healthy. 

Is Watering Plants In The Sun Bad?

Watering your plants in the sun isn’t going to do much damage to them as long as you know what you are doing.

Watering the plant in the sun helps keep the plant cooler through more transpiration and makes sure the plant will not die out of thirst.

Always check the soil before watering. if the soil surface is already moist you don’t need to water the plant even if it is in direct sunlight.

It is always best to water the soil and not the leaves. but if the weather is very dry and hot, you can use a bit of misting on the foliage. 

What Is The Best Time To Water Your Plants:

The best time to water your plants depends on the type of plant you have. Some plants prefer morning watering, while others prefer to be watered in the evening hours.

But in general, morning is the best time to water most of your plants because:

  • It allows the plant to take up the water and get ready for the heat or the dampness of the day.
  • Winds and heat are not very high so you will lose less water due to evaporation.
  • You can easily set up a daily routine to water the plants in the early morning after waking up.

You can also do evening watering if that is the time best suits your schedule.

Conclusion:

The bottom line is that there are many pros and cons to the practice of watering plants at night.

The most important thing to consider when deciding whether to water indoor plants at night or during the day is the type of plant you have.

If you have a succulent, it’s best to water it during the day as succulents are sensitive to humidity, and water at night can cause its leaves to rot.

However, if you’re looking after an avocado tree or any other tropical or subtropical plant, watering at night can be beneficial.

As always, do some research and find out what works best for you and your plants. And try not to stress about it too much.
