🌿 10 Acid Loving Plants For UK Gardens (And How to Grow Them)
Acid-loving plants are some of the most rewarding you can grow in the UK, offering vibrant flowers, evergreen structure, and even edible crops. If you’ve got acidic soil—or you’re happy to grow in ericaceous compost—there’s a huge range of plants that will thrive and bring real impact to your garden.
