Dianthus fertilization time

The flowering period of dianthus is relatively long, lasting from spring to autumn, mainly concentrated in April and May. Fertilizer can be applied at this time, basically once every 15 days.

The top dressing of dianthus needs to be determined according to its growth. Appropriate amount of top dressing should be applied after the leaves turn yellow, the plant sprouts, buds, and blooms.

What fertilizer to use for dianthus

Urea can be applied in the early stage of dianthus growth, and when it grows flowers and fruits, you can apply compound fertilizer containing nitrogen, phosphorus and potassium. This can make it fuller. Phosphorus can promote root development and increase the ability to absorb water and fertilizer, and nitrogen can help the growth of branches and leaves.

If you want dianthus to grow vigorously, you must pay attention to the indispensable trace elements, such as boron, which can make it grow stronger and taller, have more and thicker leaves, promote the differentiation of flower buds, make the flowers more colorful, and the leaves greener.

Dianthus fertilization method

Dianthus likes fertilizer, so you can increase the frequency of fertilization, but the amount applied each time needs to be reduced and the concentration should also be lowered. Generally, nitrogen fertilizer should be applied once every 15 days to promote the growth of branches and leaves. When applying top dressing, do not use too much calcium fertilizer, because calcium will resist other ions and cause the loss of other elements.

Matters Needing Attention in Fertilizing Dianthus

If chemical fertilizers are frequently used on dianthus, the salt concentration in the soil will increase, which is not conducive to its growth. Therefore, it is necessary to use them after a period of time and avoid using concentrated fertilizers to prevent fertilizer damage and the death of the plant.
