What is the reason why the leaves of the micromoon always have yellowing and spots?

Yellowing is caused by lack of water or less watering to cause yellowing of leaves. The old leaves are yellow and fall off from the bottom to the top, but the new leaves generally grow normally, and the amount and frequency of watering should be appropriately increased. ‍‍

I think it's caused by sunlight, and the intensity of sunlight determines the color.

Pay attention to the weather and other conditions, and do not let the plants be exposed to these shocks. Move the plant to an environment suitable for its growth, pay attention to temperature, light, watering, air humidity, etc., and the non-dormant plant will grow new leaves on its own after a while.

Is the pot not drained, solve the drainage problem, and then spray downy mildew in time, it can be recovered soon, if there are foot buds at the base of the seedlings, it means that the activity of the seedlings is acceptable, hurry up**downy mildew. ‍‍

The most common yellow leaves and long spots are actually caused by waterlogged roots, such as planting with porcelain pots and dense substrates, and the water cannot penetrate for a long time after watering, which will lead to the problem of stuffy roots and rotten roots. ‍‍

If there is a lack of light for a long time, it can also lead to yellowing and long spots on the leaves, for example, many flower friends put the moon season indoors for maintenance, if the light is poor, the whole will be yellow, especially the base leaves are blocked by the upper leaves, which will also lead to yellowing and long spots.

There are many reasons for the yellowing of the leaves, there are environmental factors, and there are also causes of pests and diseases, is it not that the drainage of the flower pot is not good, my flowers have had such a situation before.

As long as the leaves are yellow, you can more or less consider the problem from the root system, and exclude the problem of the root system, which is generally not a big problem, and the same is true for spots.

If the flower pot is a little impermeable, although it looks good, it is easy to accumulate water and stuffy the roots, once the substrate is too dense, and the drainage hole of the porcelain pot is too small, it will lead to watering, can not be discharged, resulting in poor growth, this is the reason why the leaves of the flower are always yellow, and the root system is too weak! ‍‍

These two diseases are extremely dependent on humidity, basically do not get sick in a dry environment, and are very easy to get sick in a humid and unventilated environment, so it is because it is too humid, generally after getting sick, you need to remove the diseased leaves in time, clean up the surface of the potting soil, do not forget about cigarette butts, tea, and leaves to throw on the potting soil, and then spray DuPont Fuxing, the environment should not be rained, keep it dry, and it will be good. ‍‍

There are many reasons for yellow leaves and long spots caused by nutrient deficiency, such as magnesium deficiency, iron deficiency, calcium deficiency, etc., which will lead to yellow leaves, especially many flower friends are planted with peat and coconut pean, and the compound fertilizer used usually does not contain medium and trace elements, and it is easy to have nutrient deficiency. ‍‍

There is a shortage of nitrogen fertilizer. It likes high-temperature plants, and likes a humid environment, avoids direct sunlight, and requires finer cultivation. You should pay more attention to the maintenance at ordinary times.

It's not a disease, it's a manifestation of foliar trauma. No need to cut it off. Try to avoid breakage.

Generally, the leaves turn yellow, and most of the cases are caused by improper water and fertilizer.
