Compost

Is ericaceous compost ok for citrus trees, please?

[Frank97]

"Compost: Citrus trees need a slightly acid environment. The pH should be between 6 and 6.5, (Lemons slightly lower pH than Oranges) so use ericaceous compost. Do not use composts containing lime as they will have a higher pH. Most multi-purpose composts also contain lime and have a fairly high pH so should be avoided. Keep the compost open by using an additive mixture such as horticultural grit, sand and grit mixture, or coarse grit. This will improve the drainage and prevent over watering. Do not be tempted to use left over builders sand as this may contain lime."
