The cultivation methods and precautions of coltsfoot

1. Maintenance methods

1. Temperature: Different growth stages have different requirements for maintenance temperature. Its native growth temperature is between 14-25 degrees. For seedlings that have just been potted, the temperature should be controlled between 14 and 18 degrees, which can promote the growth of seedlings. After entering the genitals, the temperature should be controlled at around 15 degrees during the day and around 8 degrees at night.

2. Watering: Its leaves are large and consume a lot of water. The soil needs to be kept moist throughout the growth process. After potting, you need to water the branches and leaves once every day at noon, and use the remaining water to moisten the soil. The plant does not consume much water in winter and watering it once a week is enough, unless the climate is too dry. In addition to watering the roots, the branches and leaves also need watering, generally once every one to two weeks.

3. Fertilization: In addition to solid fertilizers, liquid fertilizers can be used. When watering, you can mix a little potassium dihydrogen phosphate solution into the water once every ten days. This can promote the differentiation of flower buds of the plant. After the growth state stabilizes, you should use compound flower fertilizer, and avoid using nitrogen fertilizer. When it is flowering, you can use muddy water for irrigation, that is, add liquid fertilizer to the water, the frequency is once a month.

The cultivating soil can be a mixture of three parts of leaf mold, three parts of humus, and one part of dry fertilizer. Mix the seeds with fine sand, spread them evenly on the growing soil and cover them with fine sand.
