In the middle and later stage of seedling raising, the temperature is relatively low, it also needs fertilizer, but the concentration does not need to be too large, once a week. At the end of the period, if the temperature is more than 10 degrees, we still need to continue the operation of the previous stage. Of course, if we add a nutrient promoter to the substrate, we don't need to apply fertilizer during growth.
About five or six weeks after the seedling is raised, we can plant it in the seedbed. At this time, we need to keep it in a good ventilation state, and let it see the light. We need to add fertilizer to it regularly. Basically, the proportion of nitrogen, phosphorus and potassium used each time is 20, 10 and 20. The fertilizer is also applied once a week. Generally, the growth period is two or three times a month, so that it will have sufficient nutrients to grow better.
It is also necessary to use fertilizer when planting it or cutting it. The base fertilizer is used at this time. When applying this fertilizer, the soil cannot be very wet. If it is especially wet, it will affect the fertilizer.
We can't just apply one kind of fertilizer. We'd better use compound fertilizer, which is used for both nitrogen, potassium and phosphorus. So we can use special fertilizer, which has high nutrition and is also very balanced. There are many microorganisms in it, which have a very big effect on its growth, and it can also make flowers grow better.
