Rock gardens make brilliant features. They’re striking, low maintenance, easy to build with kids and look good all year round. Alpine plants are perfect if you’re pushed for space or want to create a stylish low-key area.
What are alpines?
They are small, compact plants originally found in mountainous and Alpine regions. Most are dwarf or slow-growing and grow best in dry, rocky outcrops.
Most garden retailers carry a wide range of alpines all year round, so head over there and choose your favourites!
Why build a rockery?
Building your own rockery couldn’t be easier. It’s the perfect challenge for a budding gardener and will last for years. Rock gardens are really low-maintenance, so you won’t need to spend loads of time and energy pruning, feeding and watering the plants.
What do I do?
Alpines like well-drained soil and are used to growing at high altitude above tree level in arid conditions. Dig out the soil and add in a mixture of grit and sand to aid drainage.
Now you can add your boulder features. Your local garden centre or DIY store will stock stones and rocks in a wide range of shapes, sizes and colours. Try and break up the area with different levels, ledges, cracks and contours to create a dramatic background for your plants.
Dig the boulders in – one third underground and two thirds above – so they are stable. As the rockery matures, the stones will naturally attract mosses and lichens that add extra colour and interest.
How do I plant it?
Dot your alpines around the rocks. My two favourites are sedums and saxifraga, but there are dozens of varieties available.
The break up the rockery with other plants to add different heights and textures. Try thrifts, sedges, rock roses, dwarf conifers and ornamental grasses. My favourite is Morning Star Deep Rose, which has rich pink flowers that contrast nicely against the grey stones.
You can also throw in some early spring and summer bulbs to add height and extra colour and scent to your rockery. Try crocus, iris and dwarf reticulata.
And to finish?
Scatter coloured gravel around the larger boulders. This gives a stylish surface finish so experiment with different textures and particle sizes to add loads of interest.
Sharp gravel will also deter slugs who don’t like its jagged edges. That’s especially beneficial for alpines whose fleshy, juicy leaves and petals are very popular with slugs and snails.
