Having plants at home is just great. Whether bought from the supermarket or even from your own garden, plants in the house bring a beautiful piece of nature into the home. However, if you put plants in your house, you should pay attention to a few things. The obvious of course that they have enough water, not too much sunlight, but also not too little sunlight. Try to follow a few other general rules when dealing with plants, wrote down in this blog post. Of course everyone knows that plants in the house are not in their natural environment and therefore require special care.
But have you ever asked why plants need sunlight like we do? Or how long can a plant survive on average without sunlight? Then you are exactly right here. In the following blog post I will answer a few unanswered questions, here and there with a few examples.
And as always, I hope you enjoy reading it!
How long can plants survive without light?
Your plant can survive without sunlight for around a week. Depending on the type of plant, the consequences are drastic.
If your plant shows brown or yellow leaves like in autumn, it has already received too little sunlight.
Not surprisingly, plants, like humans, also depend on sunlight. Even if it is of course much more drastic with plants, there are clear side effects with both: We suffer.
To prevent this, you should ensure that your plant is exposed to daylight around 6-8 hours a day. If she’s already starting to have thinner leaves, that’s another warning sign.
Can plants survive without sunlight for a week?
Plants survive for about a week without sunlight. However, this is not recommended as they need sunlight for photosynthesis.
Depending on the type of plant, a cactus does not care less than sunlight for a weekother plants, but all plants need sunlight sooner or later.
Can plants feel pain?
Plants cannot feel pain. The passing of signals in plants actually work in a pretty similar way as in humans, but the plant is missing an organ that can interpret this damage as a negative experience.
In humans, that would be the brain.
Why don’t the plants grow without light?
Plants absorb light through their green leaves, that’s how they produce theirenergy. With this energy in reserve, the plant produced sugar and starch. That is the food that a plant needs to grow. Normally plant’s can not grow without light.
Plants suck out water and nutrients directly the earth, and the air absorbs gas, called Carbon dioxide. All of these processes are necessary so that the plant can carry out a process that is important for its survival: Photosynthesis.
How to know when my plant goes bad?
Of course, that depends on the type of plant.
However, the reactions are relatively the same.If there is too little sunlight for example, the plant tries to bend (grow) towards sunlight. If that happens to your plant, make sure that your plant is not growing faster than in the past Weeks, if it does, then this should serve as a warning to you.
If your plant is not getting enough water or you think that it didn’t have enough, put your finger in the flower pot, and check if it is dry, if so, it has to be poured again.
This does not apply to cacti, they should be properly watered about once a month.
The general rule: It is a bad sign if your plant’s leaves turn brown or yellow. From that point on, it’s time to act.
Can plants cry?
Not to be confused with guttation, which is necessary to ensure transport of nutrients between soil and plant, plants can actually “cry for help”, but don’t cry out of emotions like humans do.
When plants are attacked by pathogens, they send a kind of “SOS” signal to the roots, and ask for help. The roots produce an acid that is supposed to kill the attackers.
In general, it can be said that plants are significantly more intelligent than we think. Personally, I always have pain in my stomach when I hear a tree being felled with a chainsaw, or nature getting destroyed in any way.
Do plants notice when they are eaten?
Plants have different signals that tell them when they are being eaten. So they definetly notice it, when they are eaten.
How exactly they perceive this is, of course, unknown. We do not know whether plants are conscious or not. But the fact is that it has been proven that plants have a kind of awareness.
How do trees communicate? And what about?
Trees communicate through roots. As soon as information has been transmitted, action is taken accordingly.
They communicate with each other like an organism. Scientists have recognized that plants can clearly do more than previously assumed. They can taste feel, smell, hear and see.
Even if we still do not know to what extent they perceive this, the fact, that itself is impressive.
Communication through roots
The roots of the trees is also known as the “command center”. It serves as the perception of the plant. The tip of the root socks itself out in a similar way, like a worm that worms its way through the earth and absorbs water and nutrients.
The root tip then sends the information to the leaves via the roots in height. This is also a way the tree can tell the season and reacts accordingly. For example, if there is not enough water, the leaves are ordered to close their openings.
That might sound counter productive, but it should prevent that too much water evaporates within the leaf.
Like we communicate via WhatsApp, plants communicate in a way among each other that we haven’t yet have fully understood. Just like plants probably not understand why you can get 10 minute long voice messages or far too big WhatsApp stickers sent with a thousand smileys. They instead tell each other if there are predators nearby or general danger like a fire.
When the leaves of the trees are eaten, warning signals are sent to the tree. This also applies if, for example, an animal has laid an egg on one of the leaves.The tree then produces more chemicals that affect the predators in a bad way.
Why trees are very important!
Forests are not only great for walking the dog, or to build huts together. They are also very useful for us and the environment.
And they have a very important job: the production of oxygen.
Trees release the oxygen into the air, we humans and also need animals need it to live. A fully grown tree provides roughly as much oxygen as 11 people breathe. They also process the gas CO2, carbon dioxide. Carbon dioxide, as already known, is harmful to the environment and humans.
So trees help to make the air cleaner.
The forests in danger.
But there is a big problem with that. Because more and more forests are being lost worldwide, since more trees have been felled than trees have grown back for decades.
In some countries, huge areas of forest are felled every day. This is especially important in the Rainforest, because those trees no longer produce oxygen and get carbon dioxide out of the air.
