Scientific name: Rosa
Family: Rosaceae
Common Name: Diamond Rose
Plant Type:
Miniature roses are a unique and compact variety of the rose family, known for their small size and abundant blooms. They are often referred to as "Diamond Roses" due to their sparkling, jewel-like flowers. These plants are typically the result of hybridization between Chinese roses and tea roses, making them a modern and popular choice among gardeners.
Morphological Features:
Miniature roses usually grow to a height of 30-40 cm, with short, dense stems and small, delicate leaves. The flowers are small but vibrant, ranging in diameter from 2-4 cm, and sometimes even smaller. They come in a wide array of colors, including red, white, yellow, orange, pink, purple, and more complex combinations. The flowers can be single or double-petaled and bloom continuously from April through November, depending on the climate and care provided.
These plants are ideal for small spaces such as balconies, windowsills, desks, and shelves. They also work well in bonsai displays, rock gardens, or as ornamental plants in public parks and green areas, adding beauty and color to any setting.
Growth Habits:
Miniature roses prefer full sun and do not tolerate shade well. They thrive in moderate temperatures, ideally between 15°C and 25°C. They go dormant when temperatures drop below 5°C and may struggle when it's above 30°C. For potted plants, it's important to use well-draining, nutrient-rich soil. Repotting every one to two years is recommended. Watering should be done daily in spring and autumn, twice a day in summer, and every 3–5 days in winter.
Fertilizing should be done every 10–15 days during the growing season, using liquid fertilizer, or once a month with a compound fertilizer. Reduce or stop fertilizing in summer. Pruning is essential for maintaining shape and promoting growth. During flowering, cut each flower stem at 8–12 cm, and before spring growth, prune back to 3–5 cm from the base, leaving only 3–4 main branches.
Disease and Pest Management:
Like other roses, miniature roses are susceptible to powdery mildew and black spot. To prevent these, spray a 5° Baumé solution of lime sulfur before bud break, and then apply Chitobuzu 800 times every two months after budding. This helps keep the plant healthy and disease-free. Common pests include aphids, spider mites, and leafcutter bees. These can be controlled using insecticides like 40% omethoate diluted 1000 times or malathion at 800 times.
Propagation Methods:
Miniature roses can be propagated similarly to regular roses. Cuttings are the most common method. Take strong shoots after flowering in spring or autumn, treat them with rooting hormone, and place them in a mix of river sand or perlite. Roots usually develop within 2–3 weeks. If cuttings are difficult to root, consider budding or layering instead.
Uses:
These roses are widely used for home decoration, garden design, and as cut flowers. They are especially popular as potted plants, used to enhance lawns, create floral patterns, or add color to indoor spaces. Their compact size and beautiful blooms make them a favorite among both novice and experienced gardeners.
