The balcony flowers don't grow well? These three elements are indispensable.

The balcony flowers don't grow well? Growing flowers on the balcony mainly depends on three factors: sunshine, ventilation and watering. The experience is as follows:

First, sunshine

Sunlight has two most important points for plants, one is that photosynthesis produces necessary and life-sustaining nutrients, and the other is sterilization and disease prevention. It is reported that the glass can block 50% of the ultraviolet rays, and the flowers in the balcony can not fully accept ultraviolet rays like the flowers and plants in the outdoor natural environment. For example, honeysuckle, sweet-scented osmanthus, gardenia and so on, if they wilt inexplicably, they may be related to the lack of ultraviolet rays or water.

Therefore, put flowering plants close to sunny places in spring, autumn and winter as far as possible, especially succulent plants, to make them grow healthier. But in summer, it is necessary to draw balcony curtains to shade flowers and plants; except for sun-loving plants such as Milan and jasmine, the sturdy tiger-tail orchids are placed near the window, and the rest are allowed to accept scattered light. Meat plants and summer dormant flowers are moved to the north floating window to be ventilated and reduced in the sun.

II. Ventilation

With the increasing number of flowers at home, slowly, ventilation has become the most important problem to be solved in the balcony.

For the sake of flowers and plants, it is best to open windows every day of the year. The balcony window is half open in winter and two in spring, summer and autumn. If there is someone at home, open the window to let the air flow. In this way, although the flowers and plants can not see the rain, but at least through the wind, so that their growth is more robust; the second is to reduce flowers and plants and potted soil germs to avoid the reproduction of insect pests in spring. Although this also killed some delicate flowers, the consequences of poor ventilation are more serious than those caused by cold. In particular, the lack of hot and humid air is easy to cause insect pests, the process of sterilization and disinfestation will be very long, powder medicine, liquid medicine, granular medicine multi-pruned, sprinkler irrigation combination, pruning isolation, to show the effect.

Third, watering

The use of water is artificial, and the key is to control it. As the saying goes, "diligent people raise fish, lazy people grow flowers." It is better to use water to control, but it is worst for flowers to scratch the surface and dabble; it is only possible to dry and water thoroughly.

To be on the safe side, you can refer to a simple method of water use-soaking the basin. Because the flowers and plants bought from the flower market are either planted with nutritious soil or garden soil. The nutritious soil is too loose and the garden soil is too dense. If you drench it from the beginning to the bottom, it will not be watered through.

Therefore, the flowers bought generally do not change the basin first, do not water the plants for the first few days, wait for the flowers and leaves to wilt, try to absorb water in the pot, not completely absorb the water, and then fully adapt to the environment at home, when picking up the flowerpot, put it in the basin to infiltrate, generally good flowers and plants will quickly absorb enough water, you can feel the water has reached the basin with your hands. Usually put some potassium dihydrogen phosphate (foliage liquid fertilizer or powder fertilizer) in the water, the flowers are a little more nutritious and healthier.
