What fertilizer to use for mint? Two things to pay attention to when fertilizing mint

1. Base fertilizer

When planting mint, you need to apply base fertilizer so that you can continuously provide nutrients to the plant. If it is planted in the ground, the fertilizer used should be well-rotted compost, soil and manure, combined with superphosphate and bone meal. Generally, 37,500-45,000 kg of fertilizer should be applied per hectare. The land should be deep plowed before application, and the fertilizer should be turned into the soil after application. If it is a potted plant, you can mix organic fertilizer or compound fertilizer into the potting soil.

2. Topdressing

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

2. Before flowering: Mint does not need too much nitrogen fertilizer in the later stage of growth. Too vigorous growth in the early stage can easily lead to leaf fall and lodging in the later stage. At this time, mainly apply phosphorus and potassium fertilizers to the plants, usually foliar fertilizers, which are easier to absorb.

3. Notes

1. Pay attention to the concentration: When fertilizing mint, you must pay attention to the concentration. If the concentration is too high, it will easily cause fertilizer damage. Generally, you should apply thin fertilizers frequently. In particular, we should pay attention to the amount of nitrogen fertilizer used. Too much nitrogen fertilizer will cause the plant to grow too tall, which will not only affect the appearance but also be detrimental to flowering.

2. Pay attention to the time: Foliar fertilizer should generally be sprayed on cloudy days or in the evening on sunny days. If it is done when the light is strong and the temperature is too high, the water will easily evaporate, resulting in the inability of nutrients to enter the leaves. Not only will it fail to supplement nutrition, it may also burn the leaves.
