The boxwood has a great role in landscaping. Let’s share with you today that the boxwood needs fertilization? What are the technical points of fertilization of boxwood?
The boxwood is not strict with soil requirements, and sandy soil, loam and brown land can be planted, but it is best to contain soil with abundant organic matter. Land preparation requires flatness. Combined with deep turning, add organic fertilizer, about 2000 kg per mu. Linyi Fertilizer Network Copyright
Topdressing can timely supplement the large amount of nutrients needed for seedlings during the period of vigorous growth and development, promote the growth and development of seedlings, and improve the quality. The Hokkaido boxwood needs more phosphorus in the seedling stage, while the growing season requires more nitrogen, and more potassium is needed in the fall growth period.

After planting the seedlings, 0.4% potassium dihydrogen phosphate solution may be sprayed on the foliage, preferably on cloudy days or when the air is wet in the morning and evening. Generally, three to four times of potassium dihydrogen phosphate can be sprayed on the foliar surface every month. Newly transplanted Hokkaido boxwood seedlings should be applied in the early stage, but it should be noted that the fertilizer concentration should not be too large to avoid burning new roots. In the fast-growing period of seedlings, the amount of fertilization should be increased and the number of fertilization should be increased. Not less than once a month, urea can be applied to topdressing nitrogen fertilizer, and dry and wet application can be applied. Linyi Fertilizer Network Copyright
Dry application can be applied to the ditch, and the application of the fertilizer is evenly applied to the soil of the seedlings. After the application, the shallow hoe is applied for 1~2 times to cover the soil; the ditch is used to ditch between the rows of seedlings, generally 15~ from the root of the seedlings. At 20cm, put the fertilizer into the ditch and cover the soil. When applying the ditch, it should be noted that the depth of the ditch should be in the distribution layer of the root system to facilitate the absorption of fertilizer by the seedlings.

Wet application is to dissolve the fertilizer in water and spray it on the seedbed or between rows. It is best to re-irrigate once after application to avoid burning. The application of nitrogen fertilizer should be carried out in spring and summer, and the last application of nitrogen fertilizer should not be delayed. In order to prevent seedlings from growing, reduce the wintering ability of Hokkaido boxwood seedlings. Nitrogen fertilizer must be stopped from August to September, and fertilization is mainly based on phosphorus and potassium fertilizer. Promote the lignification and root growth of Hokkaido boxwood seedlings and improve the cold resistance of seedlings. Linyi Fertilizer Network Copyright
