How to fertilize Platycodon grandiflorum

Spring fertilization

In fact, this plant does not need too much fertilizer on a daily basis, or it can be completely fertilized. Just fertilize the plant appropriately once in the spring every year. When applying fertilizer, just dig a small hole around the plant and bury the fertilizer in it. But try to keep it away from the roots of the plant and do not expose it to sunlight.

Fertilize during flowering period

Its flowering period is from July to September, and it can last for more than 3 months if properly cared for, so it needs a lot of nutrients at this time. Fertilization should be carried out before and after flowering. First, it can ensure that the flowers bloom more delicately and beautifully, and second, it is conducive to the growth of fruits. However, due to excessive nutrient consumption during the flowering period, appropriate flower thinning can be carried out to allow the roots and stems of the plants to grow better.

Fertilization at the seedling stage

During the growth stage of seedlings, apply less helium and potassium fertilizers and more phosphorus fertilizers, and at the same time, carry out reasonable topping. This will make the plants grow stronger, effectively prevent the plants from growing too tall, and avoid unnecessary nutrient loss.

Soil nutrients

When it comes to fertilization, we have to talk about the nutrients in the soil. This plant needs to grow in sandy soil with sufficient phosphorus and potassium content.

Precautions

Never allow plants to be contaminated by fertilizer at any time. If they are accidentally contaminated, rinse them with clean water in time and keep them as far away from the roots as possible.
