How Long Does It Take for Flowers To Absorb Water?

Every gardener knows that watering their flowers is crucial for them to grow healthy, strong, and beautiful. However, you may be wondering how exactly this process works, and how long it takes for flowers to absorb water.

It takes flowers a few hours to one day to absorb water. Flowers continuously absorb water in order to perform the functions the plant needs to survive, which is why watering flowers is so important to their overall growth and development.

Wondering more about what goes into this necessary process that plants perform, and what can impact how long it takes for a flower to absorb water? You’ll find everything that you need to know in the information I have for you below.

Factors That Affect a Plant’s Ability to Absorb Water

Unfortunately, not every flower is the same, and the time it takes for flowers to absorb water varies. A number of external factors can impact how quickly a flower is able to absorb water.

These factors include:

  • Light levels
  • Temperature
  • Humidity
  • Wind strength
  • The flower’s condition

In the following sections, I’ll go over these factors and how they impact a flower’s capacity to absorb water.

The Light Levels

One of the crucial processes for a plant’s survival is photosynthesis. During photosynthesis, a plant uses water, light, and carbon dioxide to produce carbohydrates. These carbohydrates act as the building blocks that a plant uses to continue growing, allowing for new growth and reinforcing existing parts of the plant.

Photosynthesis occurs when a plant is exposed to light. This process also uses water, causing the plant to absorb water more quickly when photosynthesis is occurring.

In this way, a plant will absorb water more quickly when it’s exposed to light as opposed to when the photosynthesis product is dormant, and less water is being used.

The Temperature

The temperature of a plant’s environment also impacts the rate at which that plant absorbs water.

Water evaporates more quickly in warm temperatures than in cool temperatures. This causes the plant to lose more water through the transpiration process, with more water vapor lost through holes in the plants’ leaves. This, in turn, causes the plant to absorb water more quickly in order to replace what it’s losing.

On the other hand, cooler temperatures can reduce the speed by which a flower absorbs water. Because the plant is losing water at a slower rate, it doesn’t need to replace water as quickly in order to keep growing. This causes the plant to slow down the processes it uses to absorb more water.

The Humidity Levels

The amount of moisture present in the air, also known as humidity, will greatly impact a plant’s water absorption. High relative humidity causes water to evaporate more slowly because the surrounding air is already moisture-laden. This slows a plant’s transpiration process, thereby slowing its speed of water absorption because less water needs to be replaced.

Conversely, low relative humidity will cause a plant to absorb water more quickly. More water is released into the air through the plant’s leaves in these conditions. Because the plant needs to then replace this lost water, it will absorb water more quickly in low humidity.

The Wind Strength

Just about every aspect of the weather impacts a flowers’ ability to absorb water. That includes the wind moving around a plant. Air movement around a plant causes water to evaporate more quickly.

When airflow moves around the leaves of a plant, it causes more water to evaporate through the stomata, increasing the speed of transpiration. This movement also affects water moving through the other parts of the plant, as the plant needs to redistribute moisture to areas that are losing it. Windy conditions will thus increase the speed that a plant absorbs water.

The Condition of the Flowers

In addition to environmental factors, the rate at which water is absorbed by a flower can also be impacted by human influence. For example, cutting flowers to display in a vase changes how they absorb water.

If you wish to transfer your flowers to a vase to display them outside your garden, you want to help them continue to absorb water after being cut to keep them looking full and healthy.

To encourage a cut flower’s ability to absorb water, the stem should be cut using a sharp knife to avoid crushing the stem and impeding the ability of water to flow through it. You should also use a clean vase and change the water regularly to avoid the stem becoming clogged with bacteria.

How Do Flowers Absorb Water?

Flowers absorb water through three different processes: osmosis, capillary action, and transpiration. These processes allow flowers to absorb the water and nutrients that they need to thrive.

Although knowing how long it takes for flowers to absorb water is essential as a flower owner, knowing the process flowers go through to absorb it is also a plus.

So, I’ll provide more information about how each of these processes works in the following sections.


At the base of a plant are its roots, which are connected to small tubes known as xylem. These small tubes draw water up from the ground and into the plant to give the plant the nourishment it needs to thrive. The process by which the xylem brings in water from the ground is known as osmosis.

Osmosis is the movement of water molecules from an area of low concentration to an area of high concentration through a semipermeable membrane. The xylem has water-conducting membranes that facilitate this process, drawing groundwater into the plant’s body so that it can be distributed to where it’s needed.

Capillary Action

Once the water has been absorbed from the ground into the plant’s system, the plant needs to move that water throughout its different parts to get it where it needs to be. The plant achieves this function through a process known as capillary action.

Capillary action is the phenomenon by which the forces of cohesion and adhesion cause molecules to move. Water molecules have a tendency to stick to each other (cohesion) as well as to stick to other substances (adhesion) that a plant exploits to move water through its systems.

The tension and force that acts on these water molecules force them up through a plant’s system so the water gets to where it’s most needed.


Much like our bodies are able to regulate water levels and temperature through perspiration, plants also have the ability to regulate the amount of water they hold through a process called transpiration. This process is also the primary way that water is moved throughout a plant in order to adequately nourish every part of the plant.

Transpiration is the gradual release of water vapor through tiny pores in a plant’s leaves. This process is also how a plant exchanges oxygen and carbon dioxide, creating the breathable atmosphere that humans and other animals need to thrive. This gradual release of water also helps water move throughout the plant, helping with further absorption.

The process is regulated by a part of the plant known as the stomata. These tiny holes on the underside of a plant’s leaves control the amount of water vapor that the plant releases.

When water is abundant and the plant has an excessive amount of it stored, the stomata open to release more water vapor. When water becomes scarce, the stomata close off to better preserve hydration.

Final Thoughts

Understanding how a plant absorbs water and what can affect this process will help you use water more efficiently in your own gardening. Although the time it takes for flowers to absorb water varies depending on several different factors, most flowers will absorb water within a day.

Environmental factors such as light and humidity levels, wind strength, and temperature will greatly affect how long it takes for flowers to absorb water. 

By better knowing how your plants work, you’ll be well on your way to a healthier garden that gives you everything that you desire.
