Relatively hardy agave varieties are the agave parryi, the agave neomexicana and the agave schottii. However, most other species already belong to a bright and not too warm place from autumn. They usually do not need to be cast there, but they have to be searched regularly for pests. In the spring, you should temporarily store agaves in a partially shaded place, so that they can gradually get used to the light and the heat.
Hibernate agaves in the cold houseMost Agave species tolerate short-term frost, but they should be given before the first night frosts to overwinter in a frost-free room. There the temperature should be between 5° and 10° C and it should be bright. A location in a bright staircase would therefore be well suited. Agaves often grow in desert areas in the wild and can store water in their leaves. Therefore, they generally need little water and are hardly ever used in a cold room in winter and only rarely watered at slightly higher temperatures. Instead of watering them, their leaves can also be sprayed every now and then.
As soon as the outside temperatures allow it, the agave should be released again because it grows best there. From then on it is poured more frequently and fertilized again. When transporting, pay attention to the very hard tips of the leaves, where it is easy to get injured. To avoid injury, wine corks can be placed on the ends of the leaves. Because of these thorny tips, an agave should not stand in a place where children play. At the beginning of spring, the agave first needs a half-shady place, so that it does not burn by the sun's rays, later it can be put back in a sunny spot.
Relatively hardy agave varietiesIn general, agaves are not hardy, but some species grow in mountains and are therefore used to low temperatures. These plants can spend the winter outside in a protected location with us.
The Agave parryi grows in the United States and Mexico at altitudes over 2000 meters and can therefore tolerate temperatures down to -20° C. It has gray-blue leaves, grows very slowly and is only about 60 centimeters high. To overwinter them outdoors, it is important to ensure that no waterlogging can occur at their plantation.
Even stronger frost tolerates the Agave neomexicanaoriginating from mountainous areas in Texas and Mexico. In a dry location, their frost tolerance is between -20° and -30° C. It has thick bluish leaves and is just under a meter high and just as wide.
Narrow, dark green leaves with threads has the Agave scottii, It remains quite small with about 30 centimeters and has no such sharp blade tips as other Agave species. It can withstand temperatures down to -12° C.
