Symptoms of cold in succulent plants

echeveria

A typical winter day dawns. You have breakfast, and you go to see your plants, hoping to find them as they were yesterday. When you approach them, you discover with concern that some have not had a very good night: their leaves have little dots that do not have to be there, the stems seem to be beginning to rot ... What has happened?

The temperatures have probably dropped too low, so I will tell you not only what are the symptoms of cold in succulent plants, but you will also know how to get them back.

Fall of leaves

kalanchoe oxalis

Leaf fall is one of the symptoms that we are more concerned about. If the temperature change is very abrupt, for example, if it goes from 10º to -1ºC in a matter of very few hours it is possible that it will appear from one day to the next, especially if after having reached that minimum it is difficult for you to climb back. The most sensitive plants are the Kalanchoe, but you will also see it in caudiciform plants such as Jatropha gout or the Cyphostemma juttae.

Recovery

When we see that a crass or caudiciform plant begins to lose its leaves due to the cold, although in our area there are frosts of only -1º or -2ºC, my recommendation is that protect them from inclement weather since if a cold wave comes it is difficult for them to overcome it. Keep them indoors in a bright room and you'll see how they will sprout again in spring.

Leaves turning black

Aeonium

If the leaves of a plant turn black… it is a bad sign. This is due to For a longer time than the plant has been able to bear, frozen water has been on the leaves. Plants such as Aeonium or Aloe are the most sensitive, but don't worry: as long as you see that the newer leaves are a little green and that the stem is undamaged, it will recover.

Recovery

As in the previous case, it is recommended to protect the plants from the cold indoors. If the situation worsens, that is, if the leaves fall and the stem becomes soft, cut to the right, put healing paste on the wound and do a treatment with fungicide. So there is a good chance that it will regrowth.

Red dots on the leaves

Although they can beautify the plant, the reality is that they are a symptom of cold. The good news is that of the ones we've seen this is the least worrisome. In fact, when the good weather comes the plant will grow new healthy leaves as those that are affected fall.

Recovery

In principle we can leave our plant outside without problem, but if the temperatures are going to drop more, it will be advisable to protect it.

As you can see, succulent plants tell us in various ways that they are cold. Have you found these tips helpful?

    Hello, I need to know, in a few words, how is it possible for a plant to measure the cold? And how do you count the hours and add them up? What are the genes involved and how do they work? Regarding blueberry, will it be possible to generate a variety with zero hours of cold requirement? name the season of four species of fruits, is any of them winter? describe various phenomena that plants experience in the different seasons of the year. What could be the environmental conditions perceived by the plants to trigger these phenomena? Thank you very much- I need it urgently, and I have no idea !!!!!!

  2.   Mariel said

    1- what types of responses are plants capable of producing? 2- indicate similarities and differences between, how plants relate to the environment and how animals do it? 3- why the same stimulus can generate different responses in different plant species? give examples…………

  3.   Mariel said

    What kind of response is flowering? because? is it a tropism or a nastic movement? justify answer. What advantages does the existence of varieties that respond differently to the same stimulus suppose for the species?

  4.   Mariel said

    what are plant hormones? are produced in the same way as animal hormones? justify answer. What is the difference between a tropism and a nastia? What other characteristics are each of these responses usually associated with? this is all in chapter 3, of the book biology 3, information and communication in living beings. secondary road. the truth is that we understand absolutely nothing.

  5.   Mariel said

    why does heliotropism get this name? How are phototropism, heliotropism and nictinastia alike and different?

  6.   Mariel said

    do plants have only one type of photoreceptor? substantiate answer- what biological processes are regulated by light in plants? choose a flowering plant and design an experiment to study whether it is a short or long day plant. define the hypothesis, the necessary materials and the procedure. propose possible results, corroborate according to the experimental result obtained. What are the advantages of researching an herb?

      Hi Mariel.
      Sorry, but I can't help you on this.
      A greeting.

  7.   Mariel said

    What are circadian rhythms? and the biological clock? With what external stimuli are both phenomena related? Are internal stimuli involved in circadian processes? which receptors catch them? substantiate responses. circadian rhythms are not only present in plants. What are three examples of activities that you think these phenomena influence your daily behaviors? investigate if they are related to the human biological clock.

  8.   Mariel said

    make a list with mechanical stimuli? which are the plants capable of perceiving? the responses to mechanical stimuli are elaborated by a single mechanism? Why are there no circumnutation movements in tall trees? With what function of living beings are tigmonasty and thigmotropism related?

  9.   Mariel said

    indicate vof, correct lo f. 1- the root apex only detects moisture- 2- the roots show negative hydrotropism. - 3- hydronastic movements occur from cell division. b- what type of receptors capture the hydraulic stimuli? justify answer. c- why is it important for a plant to avoid water loss? substantiate response, taking into account the different environments where plants develop.

  10.   Mariel said

    in what functions do chemical stimuli intervene? Are they produced by living beings or are they released from inanimate bodies? give examples. How do plants respond to the chemical stimuli they receive? If they grow a plant in a jar with water and a pound of sugar, what will their response be like? because?

  11.   Mariel said

    what is gravitropism? design an experiment to show that gravitropism acts as a stimulus for plants. How do you imagine that the clinostat invented by Sachs could have been used to study the effects of gravitropism? please I need help!!!!!! Thanks a lot. darlings.
