Last year's research revealed that cut flowers need "sterilized liquid," "substances that can be energy," "parts in contact with the atmosphere," "light source," and "appropriate outside temperature." Of these, the "parts in contact with the atmosphere," "light source," and "appropriate outside temperature" are adjusted so that the amount of liquid in the vase is slightly exposed, or placed in a bright place, such as an air conditioner. It can be solved by installing it in a place where it does not hit directly. However, in order to prepare other "sterilized liquids" and "substances that can be used as energy", it is necessary to devise not only simple water to be put in a vase but also other things to put in. Flower potions can replenish them quickly. However, the flower potion is not yet completed. In this year's research, I will try to clarify and complete the unexplained parts.

Don't over-nutrition
If you add too much nutrition, the flowers will die quickly. This applies not only to cut flowers, but also to flowers with roots that are mainly grown in pots. It is similar to root rot, which causes root rot due to excessive water supply. Putting flower leaves in the water causes root rot, which makes the roots and stems fragile.
