Alpines are plants found in high mountainous areas generally above the natural tree line. They are usually exposed to wide ranging temperatures: very freely draining low nutrient soils: strong winds and high light levels. To survive these conditions they have evolved a number of defences because they are low growing, mat or cushion-forming plants. They are protected against harsh winds and cold: they are dormant under snow; they have extensive root systems to seek out moisture and nutrients: they often have spiny growths to deter grazing animals. These conditions are different to a British winter but provided you bear in mind their natural growing conditions, you can grow them quite successfully.
How to grow Alpines
These dwarf plants offer a huge choice of flower colour and also of shape, foliage and a diversity of usage. Used in a rockery, spectacular displays can be achieved with the colour and form of the plants complimenting the rocks. They also make good container plants on patios and are good in old sinks and troughs and raised beds. Some will grow well in hanging baskets and in crevices in walls, or paving stones. Types such as Thyme can be planted en-masse to give a colourful and scented carpet.
Alpines in containers
Alpines can live in containers for many years and dwarf types especially benefit from being displayed in raised sinks or troughs so that their minute detail can be better appreciated. Smaller containers will need holes in the bottom to let excess water drain off. Always put a layer of broken crocks in the bottom to help with drainage and ensure the roots never sit in water. Provide a planting mix of 30% general purpose compost, 30% leafmould or garden compost and 40% added grit. Top dress with gravel and place in a sunny location. Water regularly but not excessively. Keep alpines even drier in winter, but do not allow to dry out. Feed with a general fertiliser at just a 1/4 of the manufacturers recommended strength for other plants in mid-spring. Keep free from weeds and pick off any dead leaves and prune as needed. Move pots into a cool well ventilated greenhouse in winter.
Creating a rockery
A rockery is intended to give the appearance of a rock outcrop mound in a mountanous region. The site is important and a bank is ideal, as building on a level surface seldom achieves a natural effect. The use of natural or imitation rock stone rather than broken concrete or old bricks is preferable. It is best to use one type of rock, choosing the largest pieces you can comfortably handle, although using some pieces will help give a natural effect.
When positioning your plants consider how they would appear in nature. Try to copy this natural look when building your rockery. Create pockets of suitable planting soil for the plants. To add interest vary the soil between the rocks. Bury the base of rocks and slope them back to help direct the rain into the pockets. Most alpines will tolerate any type of soil, providing it is well drained!.
Once the rockery is planted, cover the soil surface with small gauge gravel or shingle to enhance the look and keep the soil cool. Although many alpines grow on very poor soils, always water after planting and in very dry spells. Feed in spring with a general fertiliser at 1/4 strength for other plants to ensure best results.
