Tree Rose Maintenance Management Tips
Tree roses are a type of rose that should adhere to the principle of 'three parts planting and seven parts management.' However, what is particularly worth noting in production and garden applications is their uniqueness, which can enhance the practical ability to solve problems in the production and application of tree roses in gardens.
A large tree has deep roots, and the land preparation should be thorough. The roots of tree roses are from the rootstock of the rosehip, which is more developed than that of ordinary roses. Therefore, during the land preparation process for planting tree roses, deep and careful cultivation is necessary to meet the growth needs of the tree rose roots.
The flowers are abundant, and fertilization should not be weakened. Tree roses have more and larger flowers than the same variety of roses, and they consume more nutrients. On the basis of sufficient base fertilizer (5000 kg of barnyard manure and 50 kg of superphosphate per mu), special attention should be paid to top dressing with chemical fertilizers (50 to 100 grams of compound fertilizer per plant after each flowering). Never make the mistake of thinking that tree roses can reduce fertilization because they are large.
Sparse seedlings mean abundant weeds, and the task of weeding is heavy. The spacing between tree rose plants is larger than that of ordinary roses, and the fertile soil provides more space for weed growth, making the task of intertilling and weeding relatively heavy. The comprehensive application of manual and chemical weeding is indispensable and becomes a top priority in the maintenance management of tree roses.
Top-heavy and bottom-light, support and wind protection are needed. The large crown and thin trunk of tree roses give them a unique top-heavy and bottom-light characteristic, which requires the use of supports to help the trunk stabilize the disproportionately large crown. Additionally, the strong winds in the spring in the north and from July to September in the south require stable support for the tree structure.
All crowns require shaping, and detailed pruning is necessary for flexibility. Tree roses come in various shapes, such as spherical, umbrella-shaped, pagoda-shaped, and weeping branches, most of which are shaped through careful pruning by hand, making the shaping and pruning process more complex.
High water evaporation requires good irrigation. Tree roses elevate their crowns with tall trunks, and under the action of wind, the evaporation of water is naturally high. Therefore, irrigation in the winter and spring seasons should not be overlooked.
Poor cold resistance requires various solutions. Tree roses are prone to freezing in the north due to their high trunks and crowns being away from the ground, and they are often grafted, which can impede the transport of nutrients and water at the grafting point. This makes tree roses in the north and north of Beijing easily "drawn" or even frozen to death. To overcome this, measures include: strengthening anti-freezing measures in winter; changing to top-bud grafting on main branches; planting in microclimates; and fundamentally, selecting rose varieties that do not require grafting and directly cultivating them into tree roses.
Although diseases and pests are few, early prevention and control are essential. Compared to ordinary roses, the crown of tree roses is away from the ground, reducing some diseases and pests, especially those influenced by the soil. However, one should never be negligent and must adhere to comprehensive pest and disease control, with the principle of treating early, treating small, and treating thoroughly.
