Rock gardens are great features for breathing life into areas of the garden with shallow or poor soil. Alpines in particular flourish in these spots, as in the wild they grow in rocky, mountainous regions and this can be easily re-created in your garden.
Alpines are an often-underrated group of plants. They are hardy, low-maintenance, drought-tolerant and many spread easily. They often have colourful flowers and can be incorporated to brighten up any barren patch. They can also be grown in the cracks and crevices of stone, between paving slabs and in pockets on the top of walls.
So, read on to discover the best plants for your rockery garden.
How to plant alpines
Most alpines can be planted at any time of year, but they become established faster if you plant them in spring or autumn. If you are unsure of the appropriate planting time, check the label or enquire at a garden centre. Alpines are not usually fussy plants but tend to dislike waterlogged soil.
Take the plant out of its pot and tease out the roots – they naturally grow very long to seek water amongst the rocks. Plant it in the garden, backfill with gritty soil and give it a thorough watering. Remember not to overwater and bare in mind that they may not require watering more than once.
To prevent aggressive spreading, occasionally trim them back after flowering to keep them in check. For more information, see my guide on how to create an alpine rock garden.
