What fertilizer to use for dianthus

1. Fertilization method

1. It likes fertilizer, so you should add fertilizer to it more often, but the amount should be small each time and the concentration should be low. Nitrogen fertilizer is generally used to fertilize it, and it is sufficient to apply fertilizer once every fifteen days or so.

2. If you frequently use chemical fertilizers, the salt in the soil will accumulate, which can easily increase the salinity and cause serious cropping problems, so you must avoid this situation.

3. Do not use too much calcium fertilizer when fertilizing it, otherwise the calcium in the soil will antagonize other ions, such as boron ions, which will be deficient due to too much calcium.

2. What kind of fertilizer to use

1. In the early stage, just using urea can meet its fertilizer needs. When it grows to a certain extent, such as when it has flowers and fruits, you can use compound fertilizer, or fertilizer with more nitrogen and potassium. It can help transfer carbohydrates to the fruit, making it grow fuller. Phosphorus can help its roots develop better and increase its ability to absorb water and fertilizer, while nitrogen can help it grow.

2. Pay attention to the indispensable trace elements, such as boron. You can use special fertilizers, which have relatively balanced and comprehensive nutrients and contain more active substances. They can make dianthus stronger, grow taller, have more and thicker leaves, and help it bloom earlier, prolong the flowering period, make the flowers more colorful, and the leaves greener.

3. If it is a potted plant, you need to give it enough base fertilizer at the beginning. Plant two or three plants in each pot. When the seedlings grow to 15 cm, remove the buds on the top to help it grow more branches. The axillary buds should also be removed in time, otherwise it will waste nutrients and affect flowering. During the growth period, you can feed it with fermented liquid fertilizer every ten days or so.
