Regular pruning so that the roses are expected to bloom
Rose flower lovers hope that their own rose can be expected to bloom, especially in the festival flowers in full bloom, adding festive joy. A lot of flower buddies also came to consult, and they all planted a lot of Chinese rose seasons. They wanted it to bloom in batches or continue to see the rose blossoms. I told them that this is very simple, that is to do a regular pruning to control the flowering period of the Chinese rose to achieve the purpose of flowering. The rose is mainly due to the accumulation of a certain temperature will bloom, the general accumulated temperature of about 700 °C will be open. According to the physical characteristics of the rose, the time for flowering can be calculated according to the accumulation of effective temperature in the local area, and the time for pruning can be grasped to achieve the purpose of flowering. The simple method of calculating the effective accumulated temperature is the daily average temperature minus 5°C. From the day after pruning, the rose will bloom when the accumulated temperature reaches 700°C or so. However, due to the different growing season and temperature conditions, the flowering period of each rose is not the same, some are longer and some are shorter, especially the management level of the flowering period will also affect the length of flowering. In the high temperature season, the flowering period of the rose is several days to ten days. In the late spring and early summer, the flowering period of the Chinese rose is 10 to 20 days. During the early autumn and early winter, the flowering period of the Chinese rose can last for 20 to 30 days. Some varieties have a longer flowering period. If you have cultivated more roses, in order to make it turn flowering, then, as long as the pruning time is staggered, the roses are divided into 3 to 4 batches for pruning, and pruning every 10 days will make the rose continue to bloom. In order to enable the rose not only to bloom on time, but also to bloom, to open a good flower, in addition to pruning techniques, water and fertilizer conditions are also indispensable. Therefore, after the flowering of the Chinese rose, it is necessary to make up for nutrients in a timely manner and follow up with organic liquid fertilizer. The cooked cake fertilizer can be added with appropriate amount of phosphate fertilizer, and 0.5%-1% phytopromotensin and 0.3%-0.5% potassium dihydrogen phosphate are mixed to spray the foliage.
