Alpine plants are usually found decorating rocky terrains and mountains in France and Switzerland; for me, they are a lovely reminder of school vacations when I was a child. These delicate plants have gentle pastel colors, and their different shades of green are a welcome addition to any small garden.
What you need
Alpines grow well in confined spaces such as containers because they have small roots and won’t grow too big. They are also hardy in adverse weather conditions, which will prove helpful if you are gardening on a windy balcony. Alpines will grow well all year round, ensuring you have a tiny, twelve-month garden, while alpines such as thyme will thrive en masse in a container, creating a deliciously scented display. There are a few factors to bear in mind when growing alpines, but you should be able to enjoy an attractive, long-lasting garden with only a little preparation.
To grow alpines in containers, choose the potting mix carefully. The most suitable potting mix for the average alpine plant is a porous one that is full of leafmold or is nutrient-rich. If the potting mix is heavy, then lighten it by adding plenty of gravel or coarse sand and, although controversial, peat moss. I would also suggest changing the potting mix once a year for pot-grown alpines. During winter, you don’t need to water alpines, but your watering routine needs to start with the arrival of spring. This great little project will look attractive in any garden, large or small. It’s also very easy to look after because the alpines are hardy. To achieve a similar alpine effect, simply pack stones around an alpine- planted pot in a metal gabion, or pebble-holder (these are used to stabilize coastlines, hillsides, or roadsides). Gabions create an effect of sleek modernity, which is effective combined with the natural serenity of stone.
1 Drill or puncture drainage holes in the base of the metal crate (see Choosing and Preparing Pots) and add some polystyrene “crocks” or small stones.
2 Fill the crate three-quarters full with potting mix and arrange the plants until you are happy with the display.
Then fill l the crate with more potting mix until it is within 4in (10cm) of the rim.
3 Finish off your planted alpine crate with a top- dressing of washed white pebbles.
