How to fertilize delphiniums? Master the correct fertilizing method

1. Seedling stage

In the middle and late stages of seedling raising, the temperature is relatively low, and it still needs fertilizer, but the concentration does not need to be too high; apply it once a week. At the end, if the temperature is in the teens in Celsius, we should still continue the operation from the previous stage. Of course, if we have added a nutrient starter to the substrate, then there is no need to fertilize during the growth period.

2. Growth stage

About five or six weeks after seedling raising, we can plant it out in the seedbed. At this time, good ventilation should be maintained, and it should also be able to receive light. Add fertilizer regularly; basically, the ratio of nitrogen, phosphorus, and potassium used each time is 20, 10, and 20. Applying this fertilizer is also once a week. Generally, during the growth period, it is applied two or three times a month, so that it will have sufficient nutrients to grow better.

3. Planting and cuttings

When planting it or taking cuttings, fertilizer is also needed. At this time, a base fertilizer is used. When applying this fertilizer, the soil must not be made very wet; if it is especially wet, it will affect the fertilizer's effectiveness.

4. Fertilizer

We cannot apply only one kind of fertilizer; it is best to use a compound one, with nitrogen, potassium, and phosphorus all being used. Therefore, a specialized fertilizer can be used. It is highly nutritious and also very balanced, and it contains many microorganisms, which have a very great effect on its growth, and it can also make the flowers grow better.
