How to grow a medal flower well
The medal flower has become a favorite of horticulture enthusiasts with its unique sunflower shape and vibrant colors. Although this ornamental plant with a shape similar to a medal is adaptable, mastering scientific maintenance methods can bring out its best ornamental effect. This article will systematically explain the key elements for the medal flower to bloom from environmental control to daily management.
Management of growth factors of medal flowers
Accurate temperature and humidity control
Ideal growth temperature should be maintained within the range of 16-25℃, and a day-night temperature difference of 8℃ can stimulate the differentiation of flower buds. In summer, when the temperature exceeds 26℃, shading and cooling are required. In winter, temperatures above 5℃ are safe for overwintering, and short-term temperatures of 0℃ require water cutoff treatment. The matrix humidity should follow the principle of moistening when dry and wet, and the immersion pot method can prevent waterlogging and rot in the leaf heart.
Adjustment of light intensity
Ensure 6 hours of direct sunlight every day, avoiding strong sunlight exposure at noon in summer. Insufficient light can cause flower buds to close, and it is recommended to rotate the pot to ensure even light exposure. LED grow lights can be supplemented indoors, maintaining a light intensity of 8000-10000 lux.

Scientific fertilization cycle
In the growing period, apply a balanced fertilizer of 20-20-20 diluted 2000 times every 15 days, and switch to a water-soluble fertilizer with high phosphorus and potassium content (15-30-15) during the budding period. Pay attention to the principle of applying thin fertilizer frequently, stop fertilizing during high temperatures, and switch to slow-release fertilizer granules during the low-temperature winter period.
Optimization of matrix proportion
Use a mixed matrix of peat soil: perlite: vermiculite = 5:3:2, adjust the pH value to 6.0-6.5. Add bone meal and decomposed sheep manure as base fertilizer when potting in spring every year, and choose a breathable ceramic pot for better root development.

Seeding and seedling techniques
Sow in spring when the temperature stabilizes at 18℃, lay the seeds flat on the surface of the matrix and cover with a thin layer of soil 0.3cm thick, maintaining 80% humidity for about 3 days to germinate. Transplant the seedlings after 4 true leaves have grown and pinch the tips to promote side branches.
