What can I use instead of ericaceous compost?
Check that your ericaceous compost is also free of peat – it should say this on the packaging. If you have trouble sourcing peat-free ericaceous compost, make your own. Use composted bark, bracken or a combination of both as the base then add three parts by volume to one part lime-free sharp sand or perlite.

The natural tannic acid inside tea leaves leaches into the soil with rainwater as tea grounds decompose, thereby lowering the soil’s pH and increasing acidity. This poses a problem for plants that require neutral to alkaline soils but creates the ideal conditions for acid-loving plants to thrive.
