How to water and fertilize boxwood

How to water boxwood

Boxwood likes water, and when watering it, you should follow the principle of "better wet than dry". When boxwood is still a seedling, its root system is shallow, so water it in small amounts and multiple times to keep the surface soil moist. The seedlings grow quickly and require a lot of water. The amount of irrigation should be increased and the seeds should be watered thoroughly each time.

In the later stage of seedling growth, in order to prevent the seedlings from growing too tall, you should start to control watering. It is best to water them in the morning or evening, and avoid watering at noon.

Boxwood likes moisture and can adapt to rainy weather for a month in a row, but it cannot be waterlogged for a long time. When transplanting in summer or when new buds are sprouting, be careful to avoid prolonged sunlight and prevent the potting soil from being too wet.

How to fertilize boxwood

Boxwood seedlings require a large amount of phosphorus, more nitrogen when growing rapidly, and a greater demand for potassium when growth stops in autumn. After planting boxwood, you can spray 0.4% potassium dihydrogen phosphate on the leaves in the morning or evening, avoiding doing so at noon when the sunlight is strong. This can be done three to four times a month.

For newly transplanted boxwood, early fertilization should be done in time, but the concentration should not be too high to avoid burning the new roots.

During the rapid growth stage of seedlings, increase the amount and frequency of fertilization to at least once a month. In addition, nitrogen fertilizer should be applied in spring and summer, and the last application should not be later than the beginning of autumn. To avoid the seedlings from growing too tall and weakening their ability to survive the winter, use phosphorus and potassium fertilizers mainly in August and September to promote the lignification and rooting of boxwood and enhance its ability to resist the cold.
