Correct watering for gardenia and azalea
The editor introduces the topic of watering gardenias and azaleas, the related content is as follows:
Today let's talk about two flowers that are generally considered difficult to grow, gardenias and azaleas. Many flower friends' gardenias always grow sparsely, do not bloom, and the leaves turn yellow, and for azaleas, they usually only see flowers for one season when they are bought, and very few can survive more than one year.
Today, I will give you some tips to make your gardenias fill the room with flowers and your azaleas bloom so that the leaves cannot be seen.
Gardenia cultivation skills
Gardenias are woody flowers, and in fact, they are very easy to grow. They have low requirements for water, light, and fertilizer. The main reason why flower friends think gardenias are difficult to grow is that gardenias often have yellow leaves, falling leaves, and growth stagnation.
The reason for all this is that gardenias are acidic-loving flowers, and if we do not pay attention to adjusting the pH of the soil in potted gardenias, it is easy for the soil to become alkaline.
In alkaline soil, the roots of gardenias will be hindered in absorbing nutrients, which will show iron-deficiency yellow leaves, followed by weak growth, falling leaves, and growth stagnation.
1. Maintain slightly acidic potting soil
To prevent gardenias from developing iron-deficiency yellow leaves, it is necessary to pay attention to applying acidic fertilizers during maintenance.
Common acidic fertilizers include ferrous sulfate fertilizer. Some flower friends also use edible vinegar, or homemade fruit peel acidic water, lemon acidic water, etc.
I personally think that ferrous sulfate fertilizer is quite good and easy to use. You can add a little ferrous sulfate to the water every time you water and pour it into the roots together.
If you are afraid of forgetting, you can apply 1-2 grams of ferrous sulfate powder or granular formulation to the potting soil of the gardenia and simply mix it with the surface soil.
This way, with each watering, some of the ferrous sulfate will dissolve and渗透 into the deeper part of the potting soil, maintaining the acidity of the potting soil for a longer time and avoiding the trouble of repeatedly applying acidic fertilizers.
2. Abundant water and sunlight
If the soil acidity of gardenias can be maintained, they can absorb nutrients from the potting soil normally and are less likely to show yellow leaves.
Gardenias have lush branches and leaves and require a lot of water, especially in summer, when sufficient water should be provided to avoid drought. Drought can cause a large number of yellow leaves in gardenias.
At the same time, make sure to provide sufficient sunlight. Gardenias are photophilic plants, and if placed in a hidden location, they are prone to excessive growth. Sufficient sunlight is beneficial for the robust growth of gardenias.
3. Avoid excessive application of nitrogen fertilizer
Many flower friends grow gardenias well, with large plants and green leaves, but they don't bloom. What is the reason for this?
It is usually caused by improper fertilization.
If nitrogen fertilizer is applied excessively for a long time, it will cause gardenias to only grow leaves and not bloom. Therefore, it is important not to apply nitrogen fertilizer excessively and to use a balanced application of nitrogen, phosphorus, and potassium fertilizers, switching to phosphorus and potassium fertilizers one month before blooming.
Azalea cultivation skills
Azaleas bloom beautifully and have a long blooming period. Many flower friends like azaleas very much, but often cannot keep them well after purchasing.
1. Attention to potting azaleas
When potting a new azalea, it is recommended that you loosen the outer soil a bit until healthy roots are exposed, then plant it, which makes it easier for the azalea to develop roots.
If the roots are not treated, the roots of the azalea are likely to circle around in the original soil clump rather than growing into the new soil, which can lead to gradual withering after the blooming period.
How many flower friends have fallen into this pit? The azalea blooms well but gradually dies after blooming. I have also encountered this when I first started growing flowers. Loosening the outer soil clump and pruning a bit of the roots, although a small technique, has a significant impact on the survival of azaleas, so be sure to pay attention.
2. Light management
Azaleas enjoy ample light but do not tolerate direct strong sunlight. During cultivation, it is important to control the light. You can give full sunlight in spring, autumn, and winter, but in summer, including late spring and early summer, you should provide shade or place it in the shade of trees. Otherwise, excessive light can sunburn the leaves of the azalea, causing yellowing leaves and blackened, dried leaf tips.
3. Water and fertilizer management
Azaleas prefer a moist environment. When managing potted azaleas, watering should be moderate. In dry seasons, you can spray more water on the branches and leaves and the surrounding air to increase humidity. If the air is relatively dry, the leaves of the azalea can easily show dried leaf tips.
In fact, both gardenias and azaleas are very easy to grow varieties. As long as you master their acidic-loving characteristics and pay attention to adjusting the pH of the soil, they generally can grow well.
