An Introduction to Several Aspects of Perennials Management:

1. Light is beneficial for the germination of most seeds, with the exception of certain varieties like cyclamen, which require darkness during germination. After germination, seeds must be exposed to light to prevent excessive growth in seedlings.

2. Temperature, provide an appropriate temperature based on the specific variety requirements; most seeds germinate within a temperature range of 20-25°C. Both excessively high and low temperatures can directly affect the germination rate of seeds.

3. Moisture management is crucial after sowing. During winter seedling cultivation, when soil temperature is low at night, water loss is minimal, so no or minimal watering is needed during the seedling stage. If the soil temperature is higher, supplemental misting should be applied as needed during the seedling stage. In summer seedling cultivation, water evaporation is particularly rapid, and water must be replenished as the situation dictates. For very fine seeds, to avoid water washing, the pot-soaking method can be used for watering.

Remove the covering once the seeds germinate. Around 60% to 70% of the seeds should have the covering removed after the cotyledons unfurl to prevent excessive growth of the seedlings. Meanwhile, maintain the moisture level of the substrate to ensure the ungerminated seed parts' cotyledons successfully emerge from the seed coat.

5. Transplanting: It is crucial to timely transplant seedlings when they reach the appropriate stage, otherwise, it may lead to excessive growth and production delays. The timing for transplanting various seedlings differs; it should be determined based on the actual situation.
