Taking care of a blue agave is not a hard thing to do. The blue agave plant requires minimal watering and fertilizing and ideally grow in sunny areas. The blue agave is either potted or gardened.

A potted blue agave should be planted outside in the sunniest available spot. Cool and shady areas cause rotting. They should be watered during warm months when the soil is dry. Watering in the winter should be kept at limit. A slow release granular fertilizer should be used. Moreover, their pots should be replaced when their roots fill the it, or when the top of the plants become heavy. Potting compost designed for plants with thick fleshly leaves, or regular potting compost with a third of it being sharp sand should be used to after replacing the pot or container.

Gardened blue agaves should be planted in the sun or a place where they could achieve at least six hours of sunlight. Water them when they are first planted and during dry times such as summer. They do not need a lot of fertilizer, but mulched organic material is beneficial. If you want to reproduce the plant, take pups that have roots systems and separate them from the parent plant, or take seeds from flower spikes.
