Rather than just leaving the smaller Agaves to the elements, however, I've decided to put them inside translucent/transparent plastic storage containers, with heated seedling mats under them to keep them warm, in the hopes that this might approximate a Zone 9-ish or greenhouse-type environment.
|The covered porch will keep them close to the warmth of the house and out of the persistent winter rain|
|I drilled holes in the top of the storage container for transpiration, although judging by all that condensation, I wonder if maybe I should make the holes bigger.|
|I have quite a variety of small and medium-sized Agaves|
|Most of them are still in plain black plastic nursery pots. Not convinced I could keep them alive, I didn't bother re-potting them into something more stylish. If they survive the winter, that'll be one of next spring's chores|
|A third storage container also has a heated seedling mat, but the plants are too big to cover, as well as three potted Agaves that are taking their chances without bottom heat.|
|I drilled a large hole in one corner of the storage container to accommodate the electrical cord of the heat mat.|
|All three heat mats are plugged into a long outdoor-quality extension cord, which is itself plugged into an outlet beside the front door.|
I'll be keeping an eye on all these plants over the course of the winter, especially on really cold days and nights. But I hope my experiment in overwintering my Agaves works.
