Why Do Plants Need To Control The Loss Of Water

If you’re curious about why do plants need to control the loss of water, the simplest explanation is that water is essential for photosynthesis and survival in challenging conditions. Remember that water is a limiting factor for photosynthesis, and it’s one of the things you should ensure to provide for the plants you grow. If you cultivate any plant species, it’s knowledge in these areas that you must understand to avoid drawbacks. 

Below is an easy-to-understand explanation of the importance of this mechanism and how the plants actually do it. You can use the information when growing and maintaining your plants properly. Lastly, don’t forget to provide the ideal growing conditions and environment for your plants using structures like greenhouses or covers in the garden.


Why Do Plants Need To Control The Loss Of Water

Why Do Plants Need To Control The Loss Of Water And How Is This Done?

Remember that temperature and water are influential factors for the plants to conduct photosynthesis. Therefore, plants can struggle under conditions that limit these areas, so they have to adapt and conserve water. This article will discuss two ways in how plants control the loss of water shortly. 

But why do plants need to control the loss of water? Over time, different plant species such as cacti have specifically evolved to improve water retention. Besides the fact that water is a limiting factor of photosynthesis, the control of loss of water offers benefits such as cooling, better nutrient absorption, and support on the structure as the plant transpires.

By definition, transpiration refers to the loss of water in plants via water vapor. This is a beneficial process as plants need it for evaporative cooling, acquiring soil nutrients, gas exchange, and water uptake. However, plants need to control the loss of water because it is vital for driving biochemical processes. 


If water is important for plants, why do plants need to lose it for various processes?

Overall, plants depend on water for growth and productivity. Plants must always find the balance between photosynthesis and transpiration and this is only possible by controlling the loss of water. Both processes are vital to plants, but there are risks that they regularly undergo, especially during challenging conditions. 


How Plants Control The Loss Of Water

Before this article discusses the two methods of controlling water loss, it’s worth noting the factors that affect the transpiration rate. They include light, soil water, temperature, humidity, and wind. Controlling these environmental factors is something you should note to help prevent water loss on your plants. 


Method #1. Through the leaves

Plants can reduce transpiration, which controls water loss using the hairs and coatings on their leaves. You’ll notice the waxy coatings on the leaves that give off a gray cast on the surface, but some plants also have reflective white hairs instead. These coatings slow the movement of air and reduce the plant’s temperature to conserve water. 

Besides having coatings on the leaf surface, some plants have also adapted to have smaller leaves. Remember that having a smaller leaf surface area will also mean fewer stomata. And stomata is the part of the leaves where water escapes. 

Therefore, fewer stomata from the smaller leaf surface reduce water loss, as evident on plants adapted to arid climates. More so, there are plants that even have their stomata only on the bottom epidermis. This is interesting to note as the leaf has three layers, and the part that is moist and responsible for photosynthesis is the one in the middle. 


Method #2. Structural and physiological mechanisms

Besides having fewer stomata or smaller surface areas on the leaves, plants have also developed structural mechanisms to control water loss. For example, plants use water storage cells and use them after they absorb water through the roots. 


Water storage in leaves and stems

The water will not be lost but will still be readily available when the plant needs it. Depending on the species, water storage can be the leaves or stems of the plant. On the other hand, there are also physiological mechanisms to help plants conserve water.  


Specialized photosynthesis

For example, plants can control water loss through a photosynthesis method that they have developed over time. This is true with most plants that thrive in dry climates where they regulate their stomata’ opening. These plants can store carbon dioxide efficiently for use during the day and use the stomata only at night. 

With this mechanism, the plants are not at risk of water loss during drought because of the lower metabolism rate. Therefore, they can maintain the critical mechanisms that require moisture to sustain life.



It’s incredible how plants have adapted to challenging conditions to sustain life. One would be curious about why plants need to control water loss as presented in different species. In general, water is crucial for the biochemical processes of plants, including photosynthesis. 

Therefore, you’ll find leaves that have smaller leaf surface area, fewer stomata, plants with water storage, and specialized photosynthesis to combat water loss. Remember that plants need evaporative cooling, nutrient and water uptake, and gas exchange, but this is only possible with transpiration. In challenging climates and environments, plants have created mechanisms to ensure that the loss of water won’t have a drastic effect on their lives.

How to Harvest Marigold Flowers and Seeds: Tools And Tips

How to Harvest Marigold Flowers and Seeds: Tools And Tips

Want to know how to harvest marigold flowers and seeds? Marigold flowers are a mainstay in most of the gardens. They bloom beautiful flowers all season long and they’re easy to grow from seed. Knowing how to save marigold seeds is essential if you want to continue growing them the next season.

Fortunately, harvesting marigold seeds are quite quick and easy. You only need to take the seeds from the flowers and let them air dry before storing them during the winter season. You can pack it up with a container or seed packets to save even more for the next growing season. Some of the marigold flowers are edible and best to mix in your salads to add a distinct flavor to it.


Tools You’ll Need to Harvest Marigold Flowers

It’s important to wait for the perfect time to harvest marigolds since the timing is crucial to have the right quality of marigold seeds.

Tip in harvesting: While you are harvesting, simply cut each marigold flower heads using your cutting equipment or either pinch it with your finger. However, be sure not to pull the flowers as it can harm the roots of your marigolds.


Opening the Marigold

Get your paper towel and set it on a flat surface. After, hold each bloom’s base, pull-off, and discard the petals and leaves of it. Then, you will easily notice the attached seeds inside the base. In the meantime, set the prepared blooms on your paper towels for bulk removal of seeds. You may also use larger towels to manage and accommodate the abundant blooms of your marigolds.


Removal of Marigold Seeds

Marigold seeds are likely to have a long, slender, and pointed appearance. Divided ends with black color and white color on the opposite edge. Gather your blooms, pull-off all petals, and leaves, and start pulling the seeds from the base. After getting all marigold seeds, discard the base in a single place like in bins or garbage bags. After sorting, put another paper towel on another flat surface and spread the pulled marigold seeds on it.


Drying of Seeds

As mentioned above, let your marigold seeds air dry for about a week in an uncovered paper towel. It will enable them to be preserved even in frost season and will prevent it from getting rot and mold.


Seed Storing

After drying the seeds, gather them and start placing them inside your seed packets to prolong their lifespan and will still be used after the frost date. Do not use plastic bags in storing your marigold seeds because it will retain residual moisture, which will affect your marigold seeds and even get rot and mold. To avoid forgetting about your marigold seeds, put a label on it to prevent possible disposal if unlabeled.


Using Stored Seeds for Replanting

After storing your collected marigold seeds, it is perfect to plant during the growing season. You can enjoy once again the benefits of it from house beautification to an edible ingredient for your salad.

While French marigolds are smaller and bushier, having only two inches of flower head across on plants and only having six to eighteen inches height. Sizes and colors vary on its classification, having a mixed combination is pretty great, will also add more pleasant and abundant color to your garden.


The Benefits of Growing Marigolds in a Greenhouse
