Growing Succulents in Containers

For a great looking container garden, think succulents! These fleshy-leaved plants thrive in the simplest of pots and their distinctive shapes and colors provide endless opportunities for creativity.

The plants we refer to as succulents include sempervivums, sedums, aloes, kalanchoes, echeverias and other fleshy-leaved species. These plants have evolved in some of the toughest growing conditions on earth, and are actually at their best when grown in hot sun and poor soil.

Succulents lend themselves to all sorts of garden uses: in stone walls, between patio pavers, in rock gardens, and even for creating green roofs. But one of the easiest ways to grow them is in containers, specifically small dishes or troughs made from stone, terracotta, concrete or hypertufa.

Exotic succulentsSucculents can be combined with shells, bits of glass and other objects to create fantastic container gardens.

Choose a planter

Gardeners in Britain have been growing plants in troughs since the early 1900s. As farmsteads were being abandoned for the city, farmers left behind beautiful hand-hewn stone livestock troughs. Gardeners were quick to realize that these troughs provided an ideal environment for growing alpine plants and succulents. Thus were the first container gardens born!

Make a planter with hypertufa

Today, authentic stone troughs are difficult to find, and command prices of hundreds if not thousands of dollars. Ever resourceful gardeners have come up with a practical alternative: troughs, dishes and other small containers made from a mix of peat moss, perlite, Portland cement and reinforcing fibers. These materials are blended into a paste-like consistency which is then formed into a dish or trough and allowed to cure. The finished product, which goes by the name of "hypertufa," is much lighter than concrete or stone, yet has the same rustic character.

Hypertufa troughs and pots are quite readily available at local garden centers and online. You can also make your own hypertufa containers, which is a fun and relatively easy project.

Use a quick-draining soil blend

The planting medium in these containers should be well-drained and not overly rich. For most succulents, add about 25 percent builder's sand to ordinary potting soil. There's no need for fertilizer.

Plants: Hardy or not

Now for the plants! Unless you garden in zone 8 or 9, you'll want to choose either sempervivums (also known commonly as hen and chicks) or sedums. Both are usually hardy to zone 4 or 5. There are hundreds of different sempervivums to choose from. A great thing about these plants is that they create miniature versions of themselves every year (these are the "chicks"). That's a good thing, because sempervivums hybridize with abandon and it's almost impossible to get them to come true from seed. This makes it difficult to keep the named varieties straight, but it also means that there's incredible variety in colors and forms.

There are two primary types of sempervivums. The first is Sempervivum tectorum, which is relatively large in size, fleshy and has a rather open face. The second type is Sempervivum arachnoideum, which is smaller, more rounded and ball-like, and has a silvery webbing over the leaves.

Some sempervivums are hardier and more stress-tolerant than others. If you start out with several different varieties, over time you'll probably arrive at a few favorites that are particularly well adapted to your growing conditions.

Sempervivums have a round and sculptural shape. Sedums make a nice complement as they usually have a finer texture and often add a cascading element to the composition in your container. There are many sedums that are hardy to zones 4 and 5, and others that are not. Heed the hardiness ratings, or be content with treating some of the more spectacular sedum varieties as annuals.

What else can you plant with your "semps" and sedums? This is where you can get really creative. Add rocks and shells, pieces of colored glass, small mirrors or sculptural features. You'll be amazed at what fantastic little worlds you can create inside your trough or dish garden.

How to care for succulents

Caring for your succulent garden is easy. Succulents aren't cactus, and they do require consistent moisture. They will be happiest in full sun, which also brings out the colors in their foliage. Hardy succulents can be overwintered right in their containers as long as the soil doesn't get soggy and they're protected from drying winds. Gardeners in zone 4 or colder may want to provide some additional protection from cold temperatures.

Once you get start growing sempervivums and sedums, you may want to branch out and experiment with some of the tender succulents, which include echeverias, aeoniums, pachyphytums and graptopetalums. These species have fantastic foliage and make great conversation pieces. If you live in a growing zone that's colder than zone 8, you will need to overwinter these plants indoors, or treat them as annuals.

Overwintering tender succulents

Many of the most fanciful succulents are not hardy in the colder parts of the country. To carry them through the winter, bring them indoors and place them in a window with bright light. A south-facing window is ideal. Another option: Overwinter your succulents under grow lights, with the lights on for about 12 hours per day. The right amount of time depends on your lights, so adjust as needed. If your succulents are not getting enough light, they will show it by elongating their stems.
