How to fertilize lisianthus

How to fertilize

Fertilization only needs to be done once every 15 days during the growing season, but during this period, attention should be paid to the ammonium nitrogen content in the fertilizer. If the content is high, it will accelerate the growth rate of the leaves, and the size of the leaves will also exceed the normal size, becoming softer and darker in color, causing the plant to grow too tall. If the temperature is lower, the growth will be more severe. If this happens, potassium nitrate and calcium nitrate can be applied.

During the growth period of flower buds, it is necessary to choose fertilizers with more potassium nitrate to apply, which is conducive to the formation of flower buds.

Precautions

When applying top dressing, it is better to use light fertilizer rather than thick fertilizer, and it can be applied in small amounts multiple times.

If you find yellowing or burnt edges on the leaves in the summer, it means the plant needs calcium supplementation. During the growth period, if the plant feels easy to break and is very brittle, it means the plant is deficient in boron.

This plant has a high demand for fertilizer. If the base fertilizer is not applied enough during planting, it must be supplemented by topdressing, otherwise it will seriously affect the growth and flowering of the plant.

During the flowering period, the application of nitrogen fertilizer should be reduced, and the application of potassium fertilizer can be appropriately increased. When fertilizing during flowering, be sure not to allow the flowers to get contaminated with fertilizer, as this can easily burn the flowers.

After talking about fertilization, let’s talk about soil. Before planting, you must choose soil with high nutrients. Such soil is very beneficial for the planting and healthy growth of plants.
