These aren't my containers as they don't look so good right now.They're like me,the heat has gotten to them.BUT here's some pictures from the garden of things that are surviving. Guess this classifies as a container,it's a pond and holds water and plants.LOL SEDUMS And the morning glories: Enjoy the view. Kathi

Do you have anywhere warmer? Perhaps with more sun? Tree ferns are often left fully exposed on sunny hillsides after logging and do just fine, even after being battered by logging equipment. Or along roadsides. They're pretty resilient, normally. The main part that needs protection is the crown, which is where the new fronds/fiddleheads begin. You'll know it's still alive when you see bumps covered in silky brown 'hair' coming from the crown. In at least one species they may also come from the trunk. Now that summer has tentatively begun just keep an eye on the plant. It could well respond to the warmer weather. I'm wondering about cutting back the fronds for winter. D fibrosa usually has old dead fronds hanging over the trunk to provide protection from various hazards (not least of which are stray seeds which start growing on the trunk.) If they were left on and bubble wrap added. If the previous season's fronds were tied together at the top, like you do with cauliflowers, then there would be something to start the season with, perhaps. They're evergreen. Fronds die off, maybe several if there's a drought running, but they don't usually drop the lot. They can come back after fire or being stripped by equipment. They can stand being the only stems left upright - although they clearly do better with more shelter and humidity. When they're tall enough to have a trunk then the crown shows above the surrounding bush, particulary in regenerating cutover or a revegetating area after weather events have caused slips. Fairly tough. While it's little - could you make it a shelter as you would for establishing a lemon tree? Something sturdy enough to take the weight of any snow, or strong winds. Wrapped with sacking/hessian, or fleece. With horticultural plastic and fleece over the top. Then it could keep its fronds.

Best to get dead stuff off the asparagus in the fall so the asparagus beetle has no place to overwinter. This post was edited by laceyvail on Tue, Jan 27, 15 at 5:54

It looks like it's drying out too much. Indoors the air is usually pretty dry which means you need to be attentive with watering. That said, if it's kept too wet you can get root rot which shows up the same way as being too dry. When roots start to rot it restricts the plant's ability to take up water.
