If the fertility of the flower soil is very high, it is not necessary to apply base fertilizer. But if its flower soil fertility is average, it's better to add some base fertilizer to its flower soil before putting it into the basin. This can significantly improve the fertility of flower soil, so that it can provide more nutrients for plant growth and flowering.
There are many choices of base fertilizer, such as compound slow-release fertilizer, manure and soil fertilizer for livestock, and even self-made fertilizer made by self retting with rice washing water and peel. However, because the release process of slow-release fertilizer is relatively long, it can continuously increase the fertility of flower soil, so it is recommended to apply
Because flowering fertilization may shorten the flowering period, it is better not to apply fertilizer when flowering for the cultivars with short flowering period. However, the varieties with longer flowering period will consume a lot of nutrients when they bloom, so it is necessary to apply fertilizer properly to supplement nutrients, so as to help the later blooming flowers continue to open. Flower fertilizer to choose a high content of phosphorus and potassium, usually every 15 days or so can be applied.
