How to raise chrysanthemums that are short and strong, full strategy for cultivating short and strong chrysanthemums If you want to keep chrysanthemums short and strong plant types, you need to master professional maintenance skills. As a representative of short-day plants, the growth characteristics of chrysanthemums determine that its plant type management needs to start from three aspects: light, nutrition, and pruning, in order to create an ideal shape with compact branches and leaves and full flowers. Light intensity control ensures 5-6 hours of direct light every day, and full sunshine can be accepted in spring and autumn. In summer, you need to avoid the strong noon light and use a sunshade net to filter 30% of the light. In winter, a fill light is needed to maintain the light intensity of 20,000 - 30,000 lux. Precise water and fertilizer management adopts the "see dry and wet" watering method, and the soil moisture is maintained at 40%-60%. Nitrogen, phosphorus and potassium compound fertilizers (10-10-10) are applied every week during the growing period, and high-phosphate fertilizers (5-30-5) are used during the bud appearing period. Organic fertilizer needs to be completely decomposed and the dilution concentration does not exceed 1:50. Scientific picking and shaping period, 4-6 true leaves were retained for the first time, and the lateral branches were picked for the second time after germination. The pinching tool needs to be disinfected with alcohol, and the incision is 0.5cm away from the leaf axil. The spraying effect is better when combined with B9 dwarfing agent (2500ppm). Remedy plan for excessive chrysanthemums to prune long branches and find that the distance between stems and nodes exceeds 3cm. Keep the 2-3 bud points at the base, and the 45-degree oblique cut faces outwards. Apply antiseptic powder to the wound after trimming, and combine it with the basin to shade the light can prevent secondary growth. Root health management is combined with pot change to check the root system, and the main root length is retained at 15-20cm. Use 800 times carbendazim solution for immersion and disinfection, and replace it with a new substrate with 30% of perlite. Summary of the key points of four seasons maintenance in spring, the focus is on picking and promoting branching, preventing high temperatures and humidity in summer, ensuring phosphorus and potassium fertilizers (G-Y) in autumn, and paying attention to root insulation in winter. Through the three-in-one maintenance method of "light control + nutrition management + shape control" and precise pruning after excessive growth, the perfect balance between the short and strong shape and the bursting effect of chrysanthemums can be achieved.
