Suitable Outdoor Four-Season Potted Plants
Outdoor potted plants can decorate the courtyard and are easy to maintain. By choosing flowering varieties with cold-resistant characteristics, a continuous vitality in the courtyard can be achieved all year round. Reasonably mixing plants that bloom in different seasons can not only enhance the sense of spatial layering but also form a natural ecological cycle system.
Analysis of Cold-Resistant Characteristics of Outdoor Potted Plants
Key Points for梅花 (Plum Blossom) Potted Plant Maintenance
As a traditional representative of cold resistance, plum blossom potted plants can survive in temperatures as low as -15°C. It is recommended to choose ornamental varieties such as cinnabar plum and palace red plum, and mix with a matrix of decomposed leaf soil and coarse sand in a ratio of 3:1. Apply a mixture of bone meal and soybean cake fertilizer every month during spring and autumn, switch to phosphorus-potassium liquid fertilizer in summer to promote flowering, and ensure 6 hours of direct sunlight daily.
Four-Season Management of Camellia
Classic varieties such as 'Eighteen Scholars' and 'Chidam' are suitable for outdoor cultivation. In winter, cover the roots with 5cm of pine needles for insulation, and apply alum fertilizer water before the flowering period to adjust the soil pH. Pay special attention to the prevention and control of scale insects, and regularly spray the plant with sophoraflavescens solution while maintaining good ventilation.

Secrets to绣球花 (Hydrangea) Color Adjustment
New and old branch flowering varieties like 'Endless Summer' and 'Bella Anna' have more advantages. Flower color change can be achieved by adjusting the soil pH: acidic soil results in blue flowers (by adding aluminum sulfate), and alkaline soil results in pink flowers (by applying lime). Retaining the withered inflorescence in winter can form a unique landscape and protect the new buds.
Care for Roses Over Winter
Choose disease-resistant varieties like 'Longsha宝石' and 'Juice Balcony'. Before winter, do light pruning and apply fish intestine fertilizer, and wrap the trunk with burlap to prevent frost. Using the Tasha-style transverse pulling method can promote more flowering branches in spring. Alternate the use of mancozeb and carbendazim to prevent black spot disease.
Training Climbing Roses
Traditional varieties such as 'Seven Sisters' and 'White Jade Hall' are suitable for creating flower walls. Use the S-shaped binding method in early spring to guide the growth of branches, combined with potassium dihydrogen phosphate foliar fertilizer to enhance stress resistance. Remove the faded flowering branches promptly after flowering, retaining 3 buds at the base to promote the growth of new branches.
Through scientific selection of plant varieties and precise maintenance management, outdoor potted plants can achieve a visual feast of four-season rotation. It is recommended to layout in stages according to the courtyard lighting conditions, combining early spring bloomers like plum blossoms and camellias with summer and autumn bloomers like hydrangeas and roses, and coordinating with winter branch plants to create a sustainable ecological landscape system throughout the year.
