Agastache likes a high temperature and sunny growth environment. If it is not conducive to its healthy growth in a long-term shade environment, it is suitable for cultivation in an area with an annual average temperature of about 19-26 ℃. When the temperature is over 35 ℃ or below 16 ℃, agastache grows slowly, or even stops.
The best way to apply fertilizer is "whole fertilizer", such as human and animal manure, oil cake, etc. After fertilization, water should be applied, and no top dressing should be applied after Ridge sealing. In the seedling stage, the environment with higher humidity is preferred, so the area with less precipitation should be irrigated reasonably. At the same time, in the dry season to timely watering, drought protection seedlings, in the rainy season you need to do a good job drainage ditch work, to prevent water caused by plant rot.
The requirement of Agastache rugosa on soil is not strict, so it is suitable to choose sandy loam with deep and loose soil layer. It should be noted. Agastache is afraid of water, if you choose to plant agastache in low-lying areas where water is easy to accumulate, it will often lead to root rot and death.
In case of dry and rainless weather, it is necessary to irrigate water in time to resist drought and protect seedlings. If it is in rainy weather and after irrigation, it is necessary to clear ditches and drain water in time to avoid rotten roots caused by ponding.
