The golden weeping willow supplier stated that it is best to soak the cuttings in clean or running water for about 3 days before cutting the golden weeping willow seedlings to promote the rooting and germination of the cuttings. Water the seedlings in time after planting. Water the seedlings 1 to 2 times before rooting, and then every 15 days or so. In mid-to-late April, when the roots of the cuttings are formed, you can spray about 10 kg of chemical fertilizer per mu. Fertilizer is applied once every 30 days. Nitrogen fertilizer is mainly used in the early stage, and phosphorus and potassium fertilizer are mainly used in the later stage to promote vigorous plant growth and root development, and pay attention to weeding. Ditching and drainage in rainy season should be used to prevent water accumulation.
When the new shoots of the cuttings grow to about 10-15 cm, leave a vigorously growing branch as the main stem and remove all the remaining shoots. Later, cut off the side branches regularly to speed up the formation of the main trunk. Cutting reproduction can grow to 3-4 meters high and 2.5-3 cm in diameter.
