The Garden Uses of Celosia
As an ornamental and adaptable plant of the Asteraceae family, Celosia, with its bright flower colors and robust vitality, has become a popular choice for urban greening and courtyard landscaping. This article will systematically analyze the comprehensive application techniques of Celosia from garden design to planting management.
Analysis of Garden Application Scenarios of Celosia
Landscape Grouping Color Scheme
The orange gradient petals of Celosia and the pink-purple color series of Begonia form a complementary color match. Combined with the vertical lines of China pink, it can create a three-dimensional visual hierarchy. Planting 8-10 plants per square meter can form a continuous flower belt effect.
Application of Spatial Function Division
For road edging, single-row close planting (plant spacing 15cm) is used, combined with Ligustrum lucidum hedges, which can define space without blocking the view. When planting on slopes, it is recommended to arrange according to contour lines, combined with Cosmos to form a natural wild community.
Key Techniques of Celosia Planting
Substrate Proportion and Disinfection
Ideal planting soil is prepared according to the ratio of peat: perlite: vermiculite = 5:3:2, and 50g of carbendazim is added per cubic meter for substrate disinfection. Heavy clay soil needs to be mixed with 30% river sand to improve breathability.
Time and Space Management Strategy
In the northern region, it is recommended to sow in mid-April and use plastic film mulching to increase soil temperature. In the Yangtze River Valley, autumn sowing and overwintering cultivation can be implemented, with small arch sheds built in November to maintain a temperature of 5°C or above at night.
Temperature and Light Control Scheme
In the seedling stage, maintain a day/night temperature difference of 25°C/18°C and use 50% shading net to prevent sunburn. In the budding stage, increase light to 6 hours or more per day to enhance bright flower colors.
Through scientific planting management, Celosia can achieve an ornamental period of up to 180 days. The perfect integration of its ecological benefits and aesthetic value makes it an indispensable landscape element in modern gardens. Mastering soil improvement and temperature control techniques, even beginners can cultivate a colorful flower border.
