What kind of fertilizer should be applied to mint? Two points for attention when applying fertilizer to mint

Indoor cultivation of orchids requires plants to be placed on ventilated, scattered and sunny windowsills, flower shelves or desks. Peat soil, black mud, pastoral soil and moss can be used as the culture soil for cultivating orchids. When the pot soil is slightly dry, it is better to water with slightly acidic water such as rainwater, and tap water can only be used after exposure to the sun. In addition, the relative humidity of the air should be kept between 40 and 70%, which is conducive to plant growth.

1. Base fertilizer

When planting mint, you need to apply base fertilizer, which can continuously provide nutrients for the plant.If it is planted in the ground, the fertilizer is mostly decomposed compost, soil miscellaneous fertilizer, with calcium superphosphate and bone meal.Generally, 37500-45000 kg per hectare should be applied, before fertilization, soil preparation and deep ploughing should be carried out, and then fertilizer should be turned into soil after fertilization.If it is potted, you can mix organic fertilizer or compound fertilizer in the potting soil.

2. Topdressing

1. Branching stage: In the branching stage of mint, proper topdressing is needed. At this time, nitrogen fertilizer is mostly used as fertilizer, which can promote the growth of branches and leaves and make the plant more lush.Only when the plant grows well in the early stage can its yield be high, so fertilizer must be sufficient to provide it with a large amount of nutrients.

2. Before flowering: The mint does not need too much nitrogen fertilizer in the late growth stage. If the growth is too vigorous in the early stage, it is easy to cause defoliation and lodging in the late stage. At this time, the plant is mainly applied with phosphorus and potassium fertilizers, usually foliar fertilizer, which is easier to absorb.

3. Precautions

1, pay attention to the concentration: to mint fertilization must pay attention to the concentration, if the concentration is too high, it is easy to cause fertilizer damage, generally thin fertilizer applied frequently.In particular, we should pay attention to the amount of nitrogen fertilizer, if too much nitrogen fertilizer will lead to plant growth, not only will affect the appearance, but also is not conducive to flowering.

2. Pay attention to the time: The foliar fertilizer should be sprayed on a cloudy day or on a sunny day in the evening. If the light is strong and the temperature is too high, the water is easy to evaporate, so that the nutrients cannot enter the leaves. Not only cannot the nutrients be supplemented, but also the leaves may be burned.
