Fig. 1 Foxtail ferns (Asparagus densiflorus 'Myers') are a common sight in my garden.
One of my favorite container plants is the Foxtail fern (Asparagus densiflorus 'Myers'). In a pot (Fig. 1), I can move them from one place to another in the yard where an instant color is needed. Foxtail ferns develop vigorous root system along with water storage organs. This feature makes the plant a celebrity-drought-tolerant plant. As a container plant, however, the same vigorous roots system causes a slight draw back. The plant gets root-bound easily.

The problem. In my garden the super-powered roots of the Asparagus densiflorus defied the shape of its container pot (Fig. 2). It is very obvious that this plant is in a desperate need of more room to grow. Dividing the plant at this point would only mean breaking the already-broken pot. I was not sold to this idea.

The Solution. I cut off some of the roots that have been dried out from being exposed through the crack - to make room for a little bit of potting soil. Using sempervivum that are available from my garden, I planted the crack with similarly drought tolerant plants (Fig. 3).
Fig. 4 These plants (Sempervivum - hen and chicks) look like they have been there all the time.
The outcome. The crack no longer looks like a disgrace (Fig. 4). As soon as the temperatures get warmer, these "ever-living" runners will send their own roots into the thicket to join the foxtail fern's roots. Today, I saw a bird trying to get peck on the new plants which tells me that a wire around the plants might be necessary for the time being.
Finally, to avoid such thing from happening in your gardens, divide potted foxtail ferns at least every two years. For bulbous containers like the one I used here (Fig. 2 and Fig. 4) division is even more critical because at a certain point the plant cannot be pulled out without damaging the container.
A little bit of imagination can transform some problems into blessings.
