My plants are sick! Come and help!

It may be that you are watering too much

The plant was diseased. Blight is a plant disease caused by moderately parasitic pathogenic fungi, such as fungi such as pathogenic Phytophthora infestans. There are hundreds of millions of fungi and bacteria in the soil, and fungi are very harmful.

The degree of parasitism is the distance at which the pathogen leaves the soil and reaches the roots of the plant. In the low degree, in the soil, it will cause root swelling, root rot, tuber and other storage organs to decay. In the middle of the degree, it can go up to the stem base and foundation, causing necrosis and decay, which is also seen by you.

If the degree is high, it can be stems and leaves.

However, those with a high degree of parasitism do not kill the plants and absorb their nutrients until the plants dry up and die. The parasitism is not the case with a low degree of parasitism, which is not fully used in plants, and causes necrosis and decay more than in the early stage of infection, and it causes rapid damage to plants.

For fungal spore germination and bacterial reproduction, the cover must be water. So don't overwater, that's all.

Australian flame wood, also known as maple leaf apple, maple leaf bottle trunk tree.

Kind of rust-like.

1.Sunburn is a condition in which direct sunlight and insufficient moisture are not watered.

2.Contamination, to which there are contaminants.

3.Chilled.

In order to restore the normal growth of the monarch orchid after yellow leaves, it is necessary to find out the source of the disease and take corresponding measures. The method is: dig out the whole Junzi orchid to check the roots, such as rotten roots, remove the rotten parts, re-cultivate with new soil, and pad a layer of fine sand under the roots.

The potting soil should be loose humus, and the pH value (pH value) should be neutral. The soil is not dry or wet, and it has good aeration. Junzi orchid likes weak light, except for winter, summer should be placed in a place of half shade and half yang, avoid direct sunlight.

If it happens"Lack of green disease"Liquid fertilizer (such as alum fertilizer water) can be added, the main point is that the amount is less and more often, be careful not to splash the fertilizer or mud on the leaves, and the stems, such as splashing on the leaves, should be washed off with water in time. Solid fertilizers should also be applied in direct contact with fleshy roots as well.

The growth of Hawaiian coconut requires brighter scattered light, and it is necessary to avoid direct strong light, otherwise the leaf color will become pale or yellow; It has strong resistance to negative and can grow in a low-light indoor environment for a long time. Generally, it is placed indoors in a shady environment for 1 to 2 months, which will not have much impact on the ornamentation of the plants. Avoid strong light, and when placed outdoors in summer, it should be properly shaded.

Shade-resistant, can be placed anywhere indoors in spring, summer and autumn, and should be placed in a sunny place in winter.

Under high temperature and humidity conditions, Hawaiian coconut may develop brown spot and downy mildew, which can be sprayed with fungicides (such as carbendazim or tobuzin 1000 times).

Isn't it hot and dry, hehe!

2 Distribution of origins.

First of all, popularize a common sense: any plant, in the same environment, at the same time, will grow much slower in a pot than in the ground. This is because pots have limited space, and plants can absorb less nutrients, water, and roots than plants planted in the ground.

Therefore, for plants of the same size, potted plants take much more time and energy than ground planting, which is reflected in the fact that the ** is also much higher.

Judging from **, gardenias and osmanthus should be dug up and then planted in pots after being planted in the ground. In this way, the root system of the plant is already injured. It can no longer bear the transpiration of the leaves, which leads to dehydration and withering of the leaves.

The measure is to cut off two-thirds of the existing leaves as much as possible, leaving only the leaves at the tips of the branches. This reduces the transpiration of the plant, which reduces the burden on the root system and achieves a new equilibrium.

Do not spray or apply any fertilizer until the plant has no new leaves. After the new leaves grow, it is also necessary to apply thin fertilizer frequently.

Banyan (scientific name: ficus microcarpa linn.). f.
