Watering is a very important aspect of any plant planting. Especially in North China, the water demand of boxwood in spring is large, and the evaporation is large, so it is necessary to increase the amount of water to meet the needs of plant growth. Water the seedlings on the first day, the fourth day and the sixth day, and then water them according to the weather and growth conditions. In addition, it should be noted that if too much water in the soil causes the plants to fall, or too much precipitation, it is necessary to straighten, soil and firm up. In addition, pay attention to observe the soil condition and timely level or fill. Because boxwood likes water, so when watering, we should adhere to the principle of "wet rather than dry".
Middle ploughing and weeding should be combined. It is usually after rain or irrigation for weeding. In addition, in the early stage of seedlings, timely weeding should be carried out in the north in spring and autumn. In summer, weeding should be carried out, especially after rain. In addition, we should adhere to the principle of early weeding, small weeding and eradication.
It is necessary to determine the fertilizer varieties according to the different growth stages of boxwood. In the seedling stage, more phosphorus fertilizer should be applied, while in the growth stage, more nitrogen fertilizer should be applied, and more potassium fertilizer should be applied before the fall stop. In addition, the specific amount of fertilization is calculated according to the period, generally speaking, to the growth period is increasing, then it is decreasing.
During the growth period of boxwood, prune the weak branches and other redundant branches in time. And after the boxwood fruit, it is necessary to remove the heart in time to avoid consuming more nutrients and affecting the growth of boxwood. Pruning in time can ensure the healthy growth of plants.
