What is the cause of the shrinkage of the flower leaves in the heart leaf?

Light, temperature, water and fertilizer may cause the heart leaf to shrink in the daytime, so you can pay more attention to maintenance and management.

Heartleaf sunflower prefers warm and soft light, and is also suitable for semi-shady environments, so it can be placed in a place with low light for maintenance. It is watered regularly and gradually reduced after autumn, and the temperature is around 15 to 25 degrees Celsius.

First, the breeding environment.

1. Light: It likes warm and soft light, and it grows well in a semi-shady environment, but it can't be too shady. When maintaining, you can place it in a place with low light, and pay attention to the summer when it is shaded.

2. Watering: The requirements for water are not very strict, as long as you regularly water it with an appropriate amount of water to keep the potting soil slightly moist, you need to gradually reduce the amount of watering after autumn.

3. Temperature: The most suitable temperature for its growth is about 15 to 25 degrees Celsius, and it is kept above 5 degrees Celsius in winter.

4. Reasonable fertilization: When fertilizing, the heart leaf day flower is in the growth period, you can apply the trim water-soluble fertilizer once every half a month, which can promote the growth of the heart leaf day flower.

It may be that the temperature has risen in the spring, and the infected atrophy disease can be removed. Usually water-soluble fertilizer can be sprayed on the foliar surface.

When fertilizing, pay attention to the use of water and fertilizer to improve stress resistance, such as the use of special macro-element fertilizer, which can improve the ability of plants to resist pests and diseases and reduce the occurrence of pests and diseases. <>

Could it be the reason for the cooler temperatures? Spring should be better when it's coming.

How to deal with the growth of heart leaves in the middle of the day: when it grows too long, it should be appropriately shortened, and the longer branches and leaves should be cut off with scissors.

In the process of maintenance, it is necessary to prune according to the shape of the plant, usually, because of improper maintenance methods, the plant will appear dry, yellow or poor growth of branches and leaves. For such branches and leaves, they should be cut in time, otherwise it will affect its normal growth and consume the water in the soil. In addition, if there are branches and leaves on the plant that are infested by pests and diseases, all the branches and leaves should be pruned and burned together.

Heart leaf midday flower pruning method.

1. Pruning time.

Pruning heart leaf mid-day flowers requires choosing the right time. Pruning the heart leaf midflower can be carried out in spring and summer every year, and it is necessary to observe the weather before pruning and avoid pruning in rainy days.

2. Trimming tools.

It is best to choose scissors with a sharp edge for pruning, and you can not use a tool with rusty or blunt knife edge to prune the heartleaf sunflower, so as not to strain the stem of the plant during the pruning process, resulting in the normal growth of the heartleaf sunflower flower.

3. Pruning method.

When pruning the heart leaf mid-day flowers, it is necessary to take the correct pruning method. First of all, it is necessary to cut off the branches and leaves that have poor growth or cannot grow normally in the heart leaf midday to help the plant save nutrients, and at the same time, it can also make the heart leaf midday flower grow too dense or too long branches and leaves, so as to promote the plant to grow more side branches.

4. Later maintenance.

In the later stage of the maintenance of the heart leaf mid-day flower, it is necessary to provide the plant with an appropriate amount of water, soak all the soil, and provide water for the heart leaf day flower is best to use mineral-rich river water or lake water, but also need to provide reasonable nutrients for the heart leaf day flower, improve the growth rate of the plant, so that the heart leaf day flower better growth.

The solution for this flower not blooming is as follows:

1. According to today's headline information, the heart leaf midday flower likes to grow in a sunny environment, and it is necessary to ensure sufficient sunlight exposure during the bud stage, so as to promote the differentiation of flower buds to achieve the purpose of more flowering.

2. The flowering of the heart leaf in the day needs a certain amount of nutrients to roll out of the world, and the rotten liquid fertilizer can be applied every other month during the growth period, and the phosphorus and potassium fertilizer are mainly applied before the flowering period, and the nitrogen fertilizer is the auxiliary fertilizer, which is conducive to achieving the purpose of flowering.

3. Watering should be carried out regularly, for example, in spring and summer, you can water once every 2-3 days, and stop watering in autumn and winter, and keep the potting soil slightly moist.

4. It is necessary to prune by hand regularly, and cut off some of the growing branches, weak branches, diseased branches and dead branches one by one, so as to avoid excessive consumption of nutrients, and concentrate nutrition on the limbs to facilitate the growth of flower branches and achieve the purpose of flowering.

The non-flowering of the heart leaf during the day may be caused by insufficient light, too little fertilization, insufficient watering, and long-term unpruning. It is usually best to place it in a place with bright astigmatism, and apply phosphorus and potassium fertilizer before flowering. Water every 2-3 days in spring and summer, and keep the potting soil slightly moist in autumn and winter.

1. Insufficient light

Heartleaf midday flowers like to grow in a sunny environment, if there is not enough light for a long time, it will grow poorly, affecting flowering. Especially in the bud stage, we must ensure that there is enough sunlight to promote the differentiation of flower buds to achieve the purpose of more flowering. However, care should be taken to avoid bright light exposure.

2. Improper fertilization

The flowering of the heart leaf in the middle of the day needs to consume a lot of nutrients, and if the nutrients are not replenished in time during the growth period, it will lead to the phenomenon of not blooming during the flowering period. Therefore, it is best to apply well-rotted liquid fertilizer once a month during the peak growth period, apply phosphorus and potassium fertilizer before flowering, gradually reduce the application of nitrogen fertilizer, and stop fertilization during flowering.

3. Watering and moisturizing

Heartleaf midday flowers need to have enough water to bloom, if the potting soil is too dry and lacks water for a long time, it will also lead to the phenomenon of not flowering. Water regularly to keep the soil moist. Watering every 2-3 days in spring and summer, gradually reduce or stop watering in autumn and winter, and keep the potting soil slightly moist.

Fourth, prune properly

If the heart leaf mid-day flower is not pruned for a long time, it will also cause the phenomenon of not blooming. In the process of maintenance, it is necessary to prune regularly, and prune some long branches, weak branches, diseased branches and dead branches appropriately to avoid waste of nutrients, concentrate nutrition on healthy plants, and promote better growth and flowering of plants.

<>01.Overwatering causes yellow leaves.

Why is it said that too much watering will cause yellow leaves? Because the previous article has mentioned to friends, if the potting soil is too wet for a long time, then the communication between the soil and the air is not smooth, which will cause a lack of oxygen in the soil, and it is easy to make some of the roots of flowers and plants have problems and rot, once the roots have problems, the flowers and plants will not be able to breathe and absorb nutrients normally, which will inevitably cause the leaves to turn yellow and finally fall off.

Then when this symptom appears, it is necessary to control the watering immediately, and at this time you can no longer fertilize the flowers and plants, otherwise it will be worse! So I mentioned many times in the article that the potting soil for raising flowers must be loose and breathable, with such potting soil, too much water will be discharged in the first time, which can protect the roots of flowers and plants!

02.The soil causes yellow leaves.

Most of the flowers and plants we often raise at home prefer acidic soils, such as rhododendrons, camellias, smiles, and gardenias.

Orchids, white orchids, osmanthus and so on, if the potting soil used to breed these flowers and plants is alkaline, due to the lack of soluble iron and other elements that can be absorbed by flowers and plants in the alkaline soil, the leaves will gradually turn yellow!

At this time, we can often pour the fermented rice washing water.

Or mix the soil with an appropriate amount of sulfur, or pine needles.

03.No ventilation and no light cause yellow leaves.

Raising flowers at home, ventilation and light transmission are too important, if the ventilation and light transmission are poor, it is easy for flowers and plants to attract insect pests. In particular, when too much nitrogen fertilizer is applied and the branches and leaves grow luxuriantly, they are not pruned in time, resulting in insufficient light on the inner branches and leaves, which is easy to cause the leaves to turn yellow and fall off.

Therefore, in order to let your flowers and plants grow healthily, you must give them a ventilated and transparent environment, and do not place them in a dark and closed space.

04.Drought and dehydration cause yellow leaves.

Many friends should have such an experience, sometimes due to work relationship forgot to water the flowers and plants, the branches and leaves of the flowers and plants will turn yellow and dry, or watering is not watered thoroughly, although it looks like the top is wet, but the roots are still dry, but also easy to cause the leaf color to be dull and dull, the leaves wilt and droop yellow.

At this time, the flowers and plants should be watered in time, and they must be watered thoroughly when watering. What is watering? Water the flowers and plants until you see that the tray of flowers and plants has water leaching, and it is watered thoroughly.

05.Nutrient deficiencies cause yellow leaves.

Some flower friends have raised flowers for several years, but they have never changed the pot or soil, and they have not even applied fertilizer! At this time, there are no nutrients in the soil, resulting in thin branches and leaves, thin and yellow leaves.

At this time, it is necessary to turn over the pot and change the soil in time, and then apply organic fertilizer 1 or 2 times a month to solve the problem.

06.Pests and diseases cause yellow leaves.

Leaf spot disease caused by fungi and other pathogens is easy to make the leaves partially necrotic, yellow spots or patches appear, and the whole leaves are yellow and fall off in severe cases, and the yellow and green mottled spots appear on the leaves after being infected by mosaic virus.

Flowers and plants suffer from scale insects.

When insect pests such as red spiders occur, the leaves will also become partially yellow, or even the whole leaf will turn yellow and fall off. At this time, find a large cardboard box to put these flowers and plants in the cardboard box, and then light a circle of fly incense in the cardboard box, and these pests can be killed in half an hour.

The above 6 points are the reasons for the yellow leaves of flowers and plants encountered most in the process of raising flowers over the years, and of course, in other places such as too strong light, too dry air, etc., will also cause yellow leaves.
