How to look at the age of clivia
As a classic variety of indoor ornamental green plants, the age of Clivia directly affects the flowering cycle and ornamental value. Mastering the judgment skills of plant growth stages can not only understand the growth laws of plants, but also provide reference for scientific maintenance. By systematically observing plant characteristics, a complete age evaluation system can be established. Plant appearance characteristics observation method estimates the number of leaf stacks. Healthy growing Clivia has 6-8 leathery leaves per year, and the approximate growth years can be calculated through the cumulative leaf weight. It should be noted that bulb coating will be formed after the old leaves at the base naturally fall off. The actual amount of visible leaves is about 60% of the total growth. Five-year-old plants often show a "cabbage-like" expanded stem base, while the stems of young plants remain smooth and flat. Bulb development degree detection combined with pot change timing measurement of underground stem length is a highly accurate assessment method. The bulb of adult plants extends 1-2 centimeters per year, 3-5 centimeters for three-year-old individuals, and 8 centimeters for plants older than five years old. During operation, it is necessary to keep the root system intact and the cultivation substrate should be backfilled in time after measurement. Comprehensive judgment of growth status shows that the metabolic rate of plants is closely related to plant age. In the prime period (3-5 years), the leaves of Clivia are bright and plump, and the annual leaf extraction volume is stable; old plants (more than 8 years) will have characteristics such as narrowing of new leaves and shortening of leaf spacing. It is necessary to eliminate the interference of maintenance factors and combine multiple indicators for comprehensive analysis.
By systematically observing the three dimensions of leaf number, bulb shape, and growth potential energy, a multi-dimensional age assessment model can be constructed. It is recommended to establish regular growth records and verify the accuracy of judgment based on the performance of flowering periods. Mastering these practical skills can not only avoid purchasing plants with false plant age at high prices, but also provide scientific basis for rate-breeding.
