Why do plants burn?
Taking care of plants is wonderful, but of course, when you find them with burns or sick, it’s not the same. We would all like to always have a garden or a house spectacularly decorated with flowers and others, but being living beings, they can also have various problems throughout their lives.
One of the most common are sunburns , either by direct exposure (putting the plant outside) or indirectly (through a window). They can also burn easily if, when watering, we pour the water on the plants themselves and not on the ground, thus allowing the magnifying glass effect to occur, that is, the sun’s rays hitting the liquid cause burns.
Another cause of burns are those caused by frost . All plants have their own hardiness. Some resist cold and hail without problems, but there are others that just feel a little cool and have a hard time. When we go to acquire one, it is always important to ask or find out if it can be grown outdoors in our area.
Finally, another reason why they may appear burned is due to excess fertilizer . It is true that they need nutrients to be able to grow, but an excess of food harms them as much as if we never paid them. You have to be very careful with the fertilizer and carefully read the instructions specified on the container, otherwise we would run the risk of giving them more than their roots can assimilate.
How to know if they are burning?
The most frequent symptoms of burns are the following:
- Appearance of yellow or reddish and later brown spots on the leaves.
- Plants can be left without leaves.
- Flower buds do not open, even though they have been developing well.
- Growth stops, something that happens especially when the problem is caused by excess fertilizer.
- Leaves wilt or become deformed.
- The edges of the leaves appear burned.
- The root system weakens, and with it, the aerial part of the plants (stems and leaves), which will lead to the appearance of pests.
In serious cases, we could lose them. Fortunately, we can do a few things to prevent it.
How to prevent them from burning?
