How long does the Impatiens flowering period last?
I. Complete Analysis of Impatiens Flowering Period
1.1 Duration of Flowering
As the main star of the summer courtyard, Impatiens begins to reveal its beauty from early July and continues to bloom until late October. In regions with suitable temperatures in the south, it can even extend to mid-November. This super-long flowering period of 120 days makes it an ideal plant for flower bed landscaping.
1.2 Morphological Characteristics of Flowering
The butterfly-shaped flowers can reach a diameter of 3-5 centimeters. Single-petal varieties are elegant and beautiful, while double-petal varieties are dignified and luxurious. The recently cultivated multicolored Impatiens can display flowers with red, orange, and purple gradient colors on the same plant, forming a natural rainbow flower bed. Each flower lasts for 5-7 days before withering, but new flower buds constantly sprout, creating a continuous flowering display.
II. Scientific Fertilization Guide for Flowering Period
2.1 Fertilization Time Nodes
The bud formation stage (20 days before flowering) is the golden period for fertilization. It is recommended to apply a diluted potassium dihydrogen phosphate solution (1000 times) every 10 days. If the already open plants show signs of nutrient deficiency such as thin leaves and reduced flower diameter, an additional application of 0.2% liquid phosphorus fertilizer can be made.
2.2 Fertilizer Selection Taboo
High-nitrogen urea and compound fertilizers are prohibited. It is recommended to use organic phosphorus-potassium fertilizers such as bone meal (5g per plant) and fermented banana peel liquid. Special attention should be paid to avoid applying uncomposted raw fertilizers, as they can cause root burns and lead to flower drop.
III. Flowering Maintenance Techniques for Improved Efficiency
3.1 Precision Pruning Plan
When the bottom flowers begin to wilt, promptly cut the flower stem base 1cm, leaving the upper full flower buds. Pinch the tips of the elongated branches to control the plant height within the range of 30-50cm, promoting nutrient concentration to the top bud (G-Y).
3.2 Key Points for Environmental Control
Maintain 6 hours of scattered light daily and provide shading protection at noon. Keep the soil moisture between 60%-70%, and use the immersion pot method to water to avoid petal rot due to water accumulation. Maintain a temperature difference of 15-25°C at night, which is beneficial for enhancing the brightness of the flower colors.
IV. Annual Maintenance Cycle Management
Collect the black spherical seeds after flowering, and early spring greenhouse seedlings in the following year can advance the flowering period. Water once a month during the winter dormancy period, keeping the potting soil slightly dry. When repotting in the following spring, add decomposed leaf soil and perlite (3:1) to store nutrients for the new flowering period.
