Notes on summer water and fertilizer management in Peony Garden

After entering the summer, the water evaporation increased with the increase of temperature, and the bud flower bud differentiation entered a critical period. During this period, the branches and leaves grew vigorously, the nutrients accumulated rapidly, and the demand for fertilizer and water increased.

The Yellow River Basin often has “floating drought” before the early summer rainy season. At this time, watering should be timely. In June, it should be poured 2 to 3 times according to the specific conditions. After entering the rainy season from July to August, it is generally not watered. If the rainfall is too much, Also be in a timely manner.

The peony garden generally does not apply fertilizer in summer. If the fertilizer is insufficient after spring flowering, a small amount of compound fertilizer or foliar application of 0.2% to 0.3% potassium dihydrogen phosphate may be applied to increase the resistance.

The weeding of loose soil is the most arduous and important work in the summer of the Peony Garden. The most effective way to weed is to squat, and the whole garden is not left blank. This method is commonly known as "one time." It can not only remove weeds, but also keep it breathable. Pay attention to the following points when weeding the soil:

1. The ground is mainly shallow, and the depth is generally less than 5 cm. It is commonly called “spring plowing, pruning in summer”

2. The time of squatting is determined by the sensation of the situation, usually after the rain and after the watering of the soil is good.

3. Weeding should be “except for small, early, and except”. Always remove the weeds before the weeds begin to bear the seeds.

4. Use herbicides with caution. Improper application may damage the leaves of peony; 5. After the rainy weather, the weeds are mad and long, and we must pull the grass in time before we can not squat.

In order to completely cure weeds, especially malignant weeds, in recent years, many peony gardens have popularized a method of deep-turning the ground, and the effect is very good. The specific method is: before the weeds are flooded, the soil between the peony gardens is turned 20 cm deep, and the topsoil and weeds are turned into the ground together, the bottom layer of soil is facing upwards, and the grass roots are removed. Although this method is more labor-intensive, it works very well. It is basically guaranteed that the weeds are no longer flooded for 30 to 50 days.
