The requirement of the temperature of the agave is relatively high. If the temperature is too high or too low, it will cause damage to it. The minimum temperature shall not be lower than 5 ℃. Generally, it is better to keep it at about 15 ℃. In the south, it can survive the winter smoothly under normal temperature, but in the north, it needs to be placed indoors for maintenance. It is also important to avoid direct light and try to keep the plant in a dark and humid place. The weather is too cold to adjust the temperature at the right time, but the heating needs to be noted that it can not last for 24 hours, without a certain temperature difference, and must not exceed 25 ℃.
This kind of plant likes humid environment. If it is in summer, it needs to be watered every day. However, because this kind of flower is not cold resistant, it must not be watered every day in cold winter, so as to avoid damage to the hyacinth. Generally, it is better to water twice a week. It should be noted that although the number of times of watering is reduced, the soil in the flowerpot must be kept moist enough, otherwise it will have a greater impact on the plants. When watering in winter, you can use 15 ℃ warm water, but you can't exceed this temperature. Generally, the best time for watering is from 10 a.m. to 4 p.m..
In the cold winter, the sun is very precious for us. Some friends may put the agave in the sun and heat it up. But the agave likes shade and can't adapt to the direct sunlight. We just need to put it in the shade with enough light. Plants all need enough light for photosynthesis. The only difference is that the hyacinth can't be exposed to the sun for a long time.
See here I believe that you have a certain understanding of the Winter Conservation of the Agave, as long as you take good care of it, the agave is actually very good conservation.
