Dahlia is also called sweet potato flower, sweet potato flower, sweet potato flower. This kind of flower has a root stem that looks like sweet potato. Therefore, these are called, but most people are called dahlia. Let's introduce the management method of Dahlia autumn. 1. Supplement fertilizer After entering the early autumn, the temperature is low and the value is short. This kind of environment will stimulate the rapid development of the rhizome of Dahlia, so it needs to be supplemented with sufficient nutrients. However, at this time, phosphorus and potassium fertilizer should be applied to promote the fullness of the roots. We can choose phosphate II. Potassium hydrogen or a lot of flowers No. 2, we can apply once in early October, if too much is applied, it is easy to produce fertilizer. 2, do not dig out the rhizome too early Autumn is the strong season for the growth of the rhizome of Dahlia. If it is dug out too early, it will affect the expansion of the rhizome and the growth of the ball. Then when do we dig it out? We can wait until the first frost in autumn, we will find The dahlia leaves are blackened by the frost, and the roots can be harvested at this time. 3, roots harvesting matters When harvesting, cut the branches of the ground to 15 cm, then carefully clean the soil, dig out the roots, clean all the fine roots on the rhizome, then put the branches down, the roots are on, put them In a cool, ventilated position, approximately 2-3 weeks until the stem is completely dry. 4, do a good job Then mark it, prepare dried sawdust or dry sphagnum, cover the roots and store in a dry, cool, frost-free place until storage until spring. During storage, be sure to check the rhizome regularly. In the case of gray mold or rot, it is necessary to remove the damaged part with a sharp knife in time. 5, root storage matters If Dahlia wants to bloom more flowers in the coming year, we should have a relatively low temperature when storing the rhizome, so that it can fully sleep in winter, generally we put it in the 5-10 degree environment. Well, if the indoor temperature is too high, it will cause it to break the dormant period too early, and the growth will be bad in the later stage.
