Rose, rhododendron, gardenia, always can't live? Teach you a trick to open for three months.

0073, rose, rhododendron, gardenia, always can't live? I'll teach you a trick, open it for 3 months!

Rose azaleas can be said to be flowering machines, the flowering period is very long, flowering is also many, but many friends can not keep alive.

Often some flower friends come to the blue demon store to buy rose flowers and will tell the blue demon that the roses they bought before are dead, so they are afraid that they will not be able to raise them. From these flower friends, the blue demon summed up several of the number one killers of the dead rose.

Rose wilt

Rose is neither drought-resistant nor water-resistant, watering must be dry and wet, do not water at will regardless of the dry humidity of the basin soil.

Many flower friends' rose died of overwatering, causing the roses to rot and wither and die.

Yellow leaves of rose

Some flower lovers find that yellow leaves are easy to appear in their roses. in fact, the causes of yellow leaves in rose can be roughly divided into the following, which can be adjusted according to your own breeding situation.

1. Overwatering

Rose is not resistant to moisture, too much watering will cause rotting roots of rose, and then show a large number of yellow leaves, the phenomenon of falling leaves, watering must wait for the basin soil to dry before watering.

Friends who are used to using pallets should get into the habit of pouring the water out of the pallets after each watering.

2. Too dry

Some flower lovers hear that the rose can not be watered more, so they do not dare to water, do not water for a long time, or only a little water at a time, resulting in the rose is too dry and yellow.

The dry yellow leaves first occur at the bottom, a large number of bottom leaves are yellow and fall off, and the basin soil is relatively dry, basically because the basin soil is too dry, or if it has been caused by drought recently, it can be watered in time.

3. Poor ventilation

Keeping rose is very important to ventilation, good ventilation can reduce the occurrence of diseases and insect pests, if poor ventilation can easily lead to rose black spot, the phenomenon of leaf yellowing and shedding.

4. Lack of light

Rose flowers like light very much, are positive flowers, rose should ensure sufficient light, if the lack of light will also lead to rose leaves green and yellow.

If you are in love with the rose, give it the best light in your home.

5. Element deficiency

Rose pot cultivation is prone to element deficiency, because rose has more demand for some trace elements, especially when our potted soil preparation is relatively simple, it is easy to occur element deficiency.

When there are calcium deficiency, magnesium deficiency, iron deficiency and so on, there will be the problem of yellow leaves.

It is suggested that when allocating soil, the matrix should not be too single, fertilization should also use more organic fertilizer, in addition, do not use sandy soil to grow rose, it is very easy to lack elements.

Rose diseases and insect pests

Rose diseases and insect pests are more, spring aphids like rose tender, early summer red spiders like to find red spiders.

Prevention of rose diseases and insect pests should be greater than treatment, regular spray potion prevention is much better than treatment after getting sick and giving birth to insects.

From spring onwards, zinc and imidacloprid can be sprayed every half a month to meet diseases and insect pests. Indoor culture should pay attention to keeping the environment well ventilated and applying more phosphorus and potassium fertilizer to enhance the resistance of plants.

Dead leaves of rhododendron

Rhododendron flowering period is very long, flowering is also very many, is one of the more easy to burst pots of flowers, rhododendron is good to see and cut is not easy to raise, there are often yellow leaves, fallen leaves.

The yellow leaves of rhododendron usually have the following reasons:

1. Basinization of basin soil

Rhododendron is a typical acidophilic flower, potted soil is easy to be alkalized, especially in the north, it is more difficult to manage.

The alkalinization of basin soil will affect the absorption of iron ions in rhododendron, and then appear iron-deficient yellow leaves.

The performance of iron-deficient yellow leaves is that the young leaves first lose green and turn yellow, and then the leaf tips wither and yellow. The important point of basin soil alkalization is prevention. Ferrous sulfate fertilizer should be added to adjust soil acidity and alkalinity and prevent basin soil alkalinization.

2. Leaf blight

Azaleas are very prone to scorched and blackened leaf tips after blooming, which is actually caused by leaf blight. Fungicides should be sprayed every spring for timely prevention and control.

3. Too dry

When the pot soil or air is too dry, it will also cause azaleas, leaves yellowing and falling off the phenomenon.

Rhododendron watering should be dry and wet, and attention should be paid to increasing air humidity in the dry season.

4. Excessive illumination

Azaleas like light but are not sun-resistant. When the light is too strong, the leaves will be sunburned and yellow leaves will appear. Therefore, attention should be paid to shading to avoid exposure in summer.

5. New roots will not be sent.

Many flower friends will find that the newly bought azaleas gradually wither after blooming, mainly because the roots of the azaleas do not grow and the blossoms consume a lot of nutrients.

For newly bought azaleas, part of the soil mass must be broken up and roots must be trimmed to promote the emergence of new roots, otherwise it will be easy to win new roots and wither.

Yellow leaves of gardenia

Gardenia flowers are white and fragrant, very popular with flower friends, but gardenia pot planting is not easy to serve, either the leaves are yellowing or easy not to blossom.

The yellowing of Gardenia jasminoides leaves is mainly due to the alkalization of basin soil. Gardenia is also a typical acid-loving flowers, usually maintenance should pay attention to the application of acidic ferrous sulfate fertilizer, in order to adjust the soil acidity and alkalinity, especially the northern flower friends, ferrous sulfate can support ah.

Gardenia does not blossom

Many people raise gardenia with luxuriant branches but do not blossom, or the bud will wither when it grows halfway. Why is this?

The main reason why gardenia does not blossom is that there is too much nitrogen fertilizer, resulting in overgrowth. When the bud grows halfway, it is withered and yellow and falls off, which is also the reason for too much nitrogen fertilizer.

When this happens, we should stop applying nitrogen fertilizer and apply phosphorus and potassium fertilizer instead to promote the production of flower buds.
