Symptoms of sunburn in plants; How to revive burnt plants?

Study guide

Flowers and plants give freshness and freshness to our surroundings. One of the most common problems on hot days of the year is sunburn, both for plants in the yard and garden and for houseplants that you grow indoors. In this article, we will talk about the causes of sunburn in plants and how to regenerate them.

Even people who do not care about the gulp will probably be upset to see plants that have dried and turned yellow in bright sunlight. In this article, we explain the reasons for this problem and the methods of regenerating damaged plants.

Signs of sunburn on plants

Dark or white spots are one of the signs of sunburn on plants

How do we know if the plant is sunburned? The sun’s rays can cause the leaves to dry out and wither. One of the most important signs of sunburn in plants is the appearance of white or dark spots on the leaves. In this case, due to the loss of moisture, the plant soil becomes dry and hard. As soon as you see this sign, you should act immediately. Keep calm and be patient. Plants need time to regenerate.

Always remember that not every plant regenerates easily; Therefore, try to take more care of the plants that you like very much.

The cause of sunburn plants

Prolonged exposure to direct sunlight burns the leaves and withers them. This is usually more common in spring and summer; Especially if you take the plants indoors in the winter and you want to move them out of the house all at once as the weather warms up. Plants accustomed to low light during this time burn in direct sunlight. Likewise, if you move a shade-loving plant to a part of the house that receives direct sunlight, the plant will burn in the sun.

You can only save these plants if you reach them immediately.

Signs that the plant is still alive

Scrape the skin of the plant a little with your nails, if you see a light green texture, the plant can be revived.

How do we know the plant is still alive and we should try to revive it? Be patient first. Do not give up too soon; Especially if you are very interested in that plant or it is one of the rare examples of plants. Examine the plant to see if there are any signs of life in the plant:

1. Scrape a little of the stem with your fingernails

Scrape a small part of the skin or stem of the plant with a nail. Is the texture still green? If so, the plant is still alive. However, if the texture of the texture is brown, the stem is gone.

۲. Bend the stem

Gently wrap the stem around your fingers. If it is flexible, it is still alive. But if it breaks, it is gone. Examine the entire length of the stem to see if it ends where it does not break.

3. Examine the buds

Examine the flowers and leaves of the plant. Squeeze one of the flower buds with your finger. If it is still succulent and not plasticized, the plant will not die. If it becomes scaly in your hands, it means that the plant can no longer be revived. If the plant itself is somewhat viable and only the buds are in trouble, discard the plasticized, softened, or discolored buds.

Although these tests show you whether the plant can be saved or not, they may sometimes be incorrect; For example, the appearance of a plant may indicate that it survives, but the damage done to it is so severe that it cannot be compensated.

Bringing a sunburned plant back to life

Sunburned Plants - Irrigation of sunburned plants

How to revive a sunburned plant?

Step 1: Move the plant to the shade

The first thing you need to do is move the plant to a shady place so that the sun does not damage it more.

Do not do this all at once because the plant needs light.

Second stage: irrigation

Next, you need to water the plant. Remember that a plant that has lost its leaves due to sunburn does not need as much water as it used to. Give it water little by little so that it penetrates into the soil. Touch the soil with your fingers to see if it is wet. Otherwise, you may damage the roots. Later, as new leaves grow, you can gradually increase the amount of water. Once the plant is back to normal, you can water it as often as it used to.

The harder and drier the plant soil, the more water it needs.

Step 3: Separate the burned parts

Once you have watered the plant well enough, you should now remove the sunburned parts, including the flowers and leaves of the plant. If you do not do this, the plant will waste some of the energy and nutrients it needs to spend on healthy parts to repair and regenerate burned parts. Because of this he can not live. Cut the stem of the plant until it has a green texture.

If you can not easily identify, as a general rule, cut 33% of its length each time until you find green tissue.

Step 4: Fertilization

After removing the burned parts of the plant, add a little fertilizer to it. This is necessary to protect the soil and roots from sunlight and to keep the plant moist. Give less fertilizer to a plant that has no leaves. In fact, you should pour half the amount of fertilizer you applied before sunburn. There is another way and that is to give the same amount of fertilizer, but change the time interval; That is, if you used to fertilize it every week, do it once every 3 weeks.

When the plant starts to grow again, you can increase the amount and frequency of fertilization.

Changing the position of the plant at the same time as changing the season

When you want to bring back the plants you brought into the house in the winter, first put them in the sun for 2 hours and continue for 2 to 3 days. Then increase the amount of exposure to sunlight. Repeat this procedure for 2 to 3 weeks so that the plant gradually gets used to the sun. In the same way, you can bring the plants home in the cold seasons.
