How big is the flowerpot for roses?
As one of the three treasures of the courtyard, the choice of flowerpots during its maintenance process directly affects the flowering effect. Reasonably matching the size and material of the flowerpot can not only show the elegant plant type of the rose, but also create the best growth environment for the root system. Based on actual planting experience, this paper systematically analyzes the key points of selecting rose pots. The selection of the size of the rose pot is standardized and the height ratio control follows the "golden section rule." It is best to keep the total height of the plant and the height of the pot at 2:1. If the rose plant is 60cm high, you need to choose a 30cm high flowerpot. High-tube flowerpots can effectively support the growth of branches and maintain an attractive appearance with regular pruning. The principle of diameter matching is to select a small pot of 15-20cm during the seedling period, and the pot is changed every year by 5 cm. Formula for calculating adult plant diameter: crown diameter ×0.6. For example, a flowering rose with a crown width of 50cm, it is recommended to use a 30cm diameter flower pot. Special attention should be paid to avoid the phenomenon of "big pots of seedlings" and prevent stagnant water and rotten roots. Depth analysis of rose pot materials: Comparison of common materials: Plastic pots are economical but have poor air permeability and are easy to accumulate heat in summer; tile pots have good air permeability but are easy to weather and damage; porcelain pots are beautiful but have poor drainage. After experimental testing, the rough pottery basin has the highest comprehensive score. Its microporous structure can automatically adjust humidity, and the insulation effect in winter is improved by 30%. High-quality flowerpots with drainage and ventilation design must have more than 3 drainage holes, and it is recommended to lay a 2cm thick ceramsite layer on the bottom. The new root control basin adopts a sidewall opening design, and the number of capillary roots can be increased by 40% through air root cutting technology. Key points for seasonal maintenance of rose pots in spring and autumn, it is recommended to use dark pots to promote the rise of ground temperature, and replace light-colored pots in summer to reflect sunlight. In cold winter areas, the pottery basin should be moved indoors, or the plastic basin should be wrapped with insulation materials. New soil needs to be replaced and flower pots disinfected every year before germination.
Through scientific selection and maintenance, rose pots can not only become an ideal container for plant growth, but also form exquisite landscape art. It is recommended to regularly observe the plant status and adjust the basin configuration plan in a timely manner based on local climate characteristics.
