Overwintering agave shrevei — FAQ
Does agave shrevei need to come indoors for winter?
Agave shrevei is hardy to roughly USDA zone 15. That means it will not survive frost and needs to come inside. Agave shrevei is frost-tender, so overwintering means bringing it inside and letting it rest rather than pushing it to grow. Move it indoors well before the first frost, give it the brightest spot you have (light levels indoors drop sharply in winter), and keep it away from both cold window glass and hot radiators — the swing between the two does more damage than the cold itself.
When should I move agave shrevei for winter?
Bring indoors when nights start dropping below about 10°C, ahead of the first frost.
How often should I water agave shrevei in winter?
