ORIGIN Hot and dry areas of the Americas (especially Mexico); some agave species are also native to tropical areas of South America and Caribbeans.
WATERING Agaves must never be overwatered, i.e. left standing in water for a long time. Well drained soil is a must. After each watering, the substrate must dry completely. 
LOCATION A lot - a lot of sun so that the plant can develop naturally; with little light/sun the leaves become rather long and narrow. If you want the agave to enjoy its plant life and not have to fight for survival, then give the plant a nice sunny location (south window, conservatory or preferably always outside on the south side of the house). 

Agaves are not "typical" houseplants. If you cannot offer the plant a (fully) sunny location, then it is better to keep your hands off the agave.

During the winter months (at least in Europe) the plants should enjoy the dormant period with less watering at around 10-15C. The combination of low temperatures with overwatering might kill your plants. 

Once taking your plants after the winter dormant period out of your winter plant storage outside, make sure that they always get full sun / UV light protection for the first 1-2 weeks, otherwise the plants will be burned. Each plant needs to get use to the sun light after the winter.


There are also several species (e.g. A. Neomexicana, A.Havardiana, A.Parryi, A.Lechuguilla, A.Filifera, A.Gentryi etc.), which are hardy (some of them up to minus 15-120C). Once the hardy agaves are planted out, most varieties require "dry feet" and "dry head" in the winter, i.e. protection against the rain and/or snow. Plant your hardy agaves always in the spring so that they have almost full year to root properly prior the winter. 

Agaves are flowering just ones upon their life time. After the blossom the plants die (create however hundreds of seeds or new baby plants).

Tequila is made from A. Tequilana (also called Weber blue agave plant).
