As the Earth makes a 365-day journey around the Sun, some parts of the planet will receive less sunlight at certain times of the year. In these regions, the days are getting shorter and the nights are getting longer. Autumn comes and then winter. Trees respond to reduced sunlight by producing less and less chlorophyll. Eventually the tree stops producing chlorophyll. When this happens, the carotenoid already present in the leaves may finally come out. Leaves become a vibrant rainbow of glowing yellows, sparkling oranges and warm browns.

You may have noticed that after a few years, the colors of the red fall seem brighter and brighter than in other years. Temperature and cloud cover can change into different tree colors from year to year. When several warm sunny days of autumn and cool but not frosty nights come one after another, it will good year for the reds. IN daytime the leaves can produce a lot of sugar, but the cool nighttime temperatures prevent the sugar juice from flowing through the leaf veins and down the branches and trunk. Researchers have found that anthocyanins are produced as a form of protection.

They allow the plant to restore nutrients to the leaves before they fall off. This helps make sure the tree is ready for the next growing season. Anthocyanins give the leaves vibrant, brilliant hues of reds, purples, and raspberries.

The amount of rain per year also affects the color of autumn leaves. A severe drought can delay the arrival of autumn flowers by several weeks. A warm, humid period during the fall will reduce the intensity or brightness of the fall colors. A hard frost will kill the leaves, turn them brown and cause them to fall early. The best fall colors come when they were.

Warm, humid spring summers that aren't too hot or dry, and fall with plenty of warm, sunny days and cool nights. You can use leaf color to help identify different types trees. Look for these leaf colors on trees in your area.

Oaks: red, brown or light brown. Products: golden bronze. Dogwood: purple-red.

• Sugar maple: orange-red.
• Maple: luminous yellow.
• Maple: bright scarlet.

As the autumn light wanes, the veins that carry the sap in and out of the leaf gradually close. A layer of cells called the separating layer forms at the base of the leaf stem. When this layer is completed, the leaf is separated from the fabric that connects it to the branch, and it falls. The separating layer never completely separates the dead oak leaves and they remain on the tree during the winter.

Evergreen trees - pines, firs, cedars, and spruces - do not shed leaves or needles in winter. The needle is coated with a strong wax coating, and the fluids inside the cells contain substances that resist freezing. Evergreen leaves can live for several years before they fall off and are replaced by new growth.

On the ground, fallen leaves are destroyed by bacteria, fungi, earthworms and other organisms. Decayed leaves replenish the soil with nutrients and become part of the spongy layer of humus on the forest floor that absorbs and retains rainfall. In nature, nothing is wasted!

If you've ever been a concerned plant owner, then you probably know that yellowing of the leaves is one of the first signs that your plant is uptight. But with possible root causes ranging from diving, to over-saturation, to a pest problem, it can be difficult to get to the bottom of your plant's disease. The next time you need to diagnose a sick houseplant, consider this step-by-step guide.

Step 1: Check "Moisture Voltage"

If you notice your plant's leaves are turning yellow, get ready to play the plant therapist and check for signs of stress. The most common stressor for plants is too much or too little water. To test how much moisture you have growing, press your finger about an inch into the plant's soil.

If the soil is dry an inch below the surface, your plant is probably thirsty. If the soil seems wet an inch below the surface, your plant may be getting enough water or it may be waterlogged. Check for signs of root rot, such as moldy smell. If you suspect your plant is waterlogged, adjust your watering schedule and consider moving your plant to a container with better drainage so the roots don't sit in a pool of water.

Step 2: Look for Unwanted Reeds

While overwatering and overwatering are the two most common causes of leaf yellowing, if you've ruled them out as potential causes, pest infestation may be to blame. Although difficult to see with the naked eye, mealybugs or spider mites can provoke your plant.

Diagnosis: If there are pests, you are likely to notice other signs of intrusion upon close inspection. Are there tiny holes in the leaves? This may indicate that they are breaking. Have you noticed fluffy white wax in your plant? To suppress infestations, try rinsing your plant, trimming diseased, wilting leaves, or douching your plant with a store-bought insecticide spray or neem oil.

Step 3: Let them soak up the sun

Another likely reason your plant's leaves are turning yellow is because they are hungry in the sun. If your apartment doesn't get a lot of natural light, it might be time to book your next sunbathing session.

Diagnostics. If your plant is in a shady corner, consider moving it permanently into a sunny spot or letting it soak up the sun near a window for a few hours. Watch the plant closely to see how it handles a lot of movement, as some sensitive plants can make it difficult to set up after a move. This may seem obvious, but if your indoor plant is next to a window with blackout curtains, you often forget to open it, remember that even if you are not at home to enjoy the sun during the day, your plant is.

Step 4: Protect Them From Cold Projects

Many varieties indoor plants are tropical, and predictably not big fans of cold weather and drawing houses. If you keep your palm next to a see-through window, don't be surprised if the leaves turn yellow.

Inappropriate temperature and poor lighting

Diagnosis: Think about whether your plant is likely to catch a cold and remember that drafts are not possible, but excessive active air conditioning can also be the cause. Also keep in mind that the colder Environment the less often. You may need to water the plant because the moisture in the soil does not evaporate as quickly. A cold draft can not only make your plant cold, but also littered with water.

We all enjoy the colors of autumn leaves. The changing fall foliage never ceases to amaze and delight us. Have you ever wondered how and why a falling leaf changes color? Why does the maple leaf turn bright red? Where do yellows and oranges come from?

To answer these questions, we first need to understand what leaves are and what they do. Search now "autumn foliage" Find maps, dates and the best stage drives for autumn colors. Leaves are nature's food plants. Plants take water from the soil through their roots, take gas from carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into oxygen and glucose. Oxygen is a gas in the air that we need to breathe. Plants use glucose as food for energy and as a building block for growth.

Lack or excess of nutrients

The way plants convert water and carbon dioxide into oxygen and sugar is called photosynthesis. It means "to connect the light". Chemical substance, called chlorophyll, helps make photosynthesis. Chlorophyll is what gives plants their green color.

Autumn preparations for winter

As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to start preparing for winter. In winter, there is not enough light or water for photosynthesis. The trees will rest and live off the food they have stored during the summer. They are starting to close their food factories. Green chlorophyll disappears from the leaves.

Improper care is the most common cause of yellowing leaves

As the bright green light fades, we begin to see yellows and oranges. A small number of these flowers were in the leaves all the time. We simply cannot see them in the summer because they are covered in green chlorophyll. The vibrant reds and purples we see in the leaves are mostly made in autumn. In some trees, such as maples, glucose enters the leaves after photosynthesis has ceased. Sunlight and cool autumn nights cause the leaves of online slots to turn this glucose red.

Easy Reading - Colors of Autumn Leaves

The brown color of trees, such as oaks, is made from waste left in the leaves. It's a combination of all these things that make beautiful flowers autumn foliage that we enjoy every year. They take water from the earth through their roots. They take a gas called carbon dioxide from the air. They convert water and carbon dioxide into food and oxygen. Oxygen is a gas in the air that we need to breathe.

Plants make their food using sunlight and something called chlorophyll. Chlorophyll gives leaves their green color. Winter days are short and dry. Many plants stop cooking in autumn. Then we can see orange and yellow colors. These colors have been in the leaves all summer, but the green has covered them.
