About Lingonberry 'Koralle'

Vaccinium vitis-idaea 'Koralle' · also called Koralle lingonberry · edible

'Koralle' is a heavy-cropping, ornamental lingonberry cultivar from the Netherlands, valued for abundant glossy red berries and a compact, tidy habit. Like the species it is a low evergreen subshrub needing acidic, peaty, free-draining soil and cool conditions. It is self-fertile and typically fruits twice, in summer and again in autumn.

Preferred mix: Strongly acidic, peaty, free-draining

Watch for — Lime-induced chlorosis: Hard tap water or alkaline soil yellows the leaves. Use rainwater and ericaceous compost to keep the root zone acidic and the foliage glossy green.

Why lingonberry 'koralle' needs this mix

Lingonberry 'Koralle' is a true acid-lover — it physically cannot take up iron above about pH 5.5, so an ericaceous mix is not optional, it is survival.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons lingonberry 'koralle' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Planting lingonberry 'koralle' in standard compost or limey garden soil. Without an acidic (ericaceous) medium it will yellow and fail no matter how well you water and feed it.

pH — does it matter for lingonberry 'koralle'?

This is the whole game: Lingonberry 'Koralle' needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

Bagged ericaceous compost is the correct, easy base for lingonberry 'koralle'; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.

Drainage and the pot

Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.

Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. When the time comes, our repotting guide for lingonberry 'koralle' covers the timing and technique step by step.

Lingonberry 'Koralle' soil — frequently asked questions

What is the best soil mix for lingonberry 'koralle'?

3 parts ericaceous (acidic) compost : 1 part composted pine bark or pine needles : 1 part perlite or coarse grit. Lingonberry 'Koralle' has evolved on acidic, peaty ground and depends on soil fungi that only function in acid conditions — raise the pH and it starves even in "rich" soil.

Can I use normal potting soil for lingonberry 'koralle'?

Ordinary multipurpose or garden compost is far too alkaline for lingonberry 'koralle' — expect classic yellowing, weak growth and a slow decline over a season or two. Bagged ericaceous compost is the correct, easy base for lingonberry 'koralle'; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.

Does lingonberry 'koralle' need a special pH?

This is the whole game: Lingonberry 'Koralle' needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.

Should I buy a bagged mix or make my own for lingonberry 'koralle'?

Bagged ericaceous compost is the correct, easy base for lingonberry 'koralle'; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.
