We recently shared a video demonstrating how to harvest the small, young plants from a bloomed Smooth Agave (Agave desmettiana).

We harvested several bulbs and have been propagating these drought tolerant succulents for the Maricopa County Master Gardeners Fall Festival and Plant Sale. Hope to see you there!

I'm new to the area and I've noticed a lot of ants in my landscape. Is there a good way to control them?
