Cultivation: Agave lophantha
"QUADRICOLOR" is a relatively easy-to-grow species. Suited for
light shade to
full sun, but better with some shade in
summer.
Needs a very well-drained soil. It grows fairly
fast in summer if provided with copious water, but allow to dry
thoroughly before watering again (the more water and fertilizer this
plant gets, the faster it will grow). During the winter months, one
should only water enough to keep the leaves from shrivelling.
Agave lophantha is
frost tolerant to -12°, but this
cultivar is more
tender (can survive to at least – 6°, particularly when
dry)... but it is best to avoid
freezing temperatures, it's too beautiful to risk not covering it on
cold nights.
It does great in containers or in the ground. Plants cultivated outdoors
are more drought tolerant and can take some heat and full sun.
Remove suckers to show off the beauty and form of the individual rosette.
Propagation:
Exclusively by
suckers, which often are found growing around the base of the
plant, Remove the basal suckers (if available) in spring or summer
and let the cuttings dry for a few days before inserting into compost.
