About Queen Pineapple
Ananas comosus 'Queen' · also called Queen pineapple, Australian pineapple · tropical
Queen is an older pineapple cultivar with smaller, deep-yellow, intensely aromatic fruit and spinier leaves, popular as a fresh dessert pineapple. It is more compact and more cold-tolerant than commercial types but still frost-tender. Care is standard Ananas: full sun, warmth, fast-draining soil and sparing water, and it propagates readily from its crown.
Preferred mix: Light, free-draining sandy or loamy mix
Watch for — Crown rot from excess water: Water pooling in the rosette or in heavy soil rots the crown; water sparingly, keep the cup dry in cool spells and use a free-draining mix.
Why queen pineapple needs this mix
Queen Pineapple 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.
- Queen Pineapple 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.
- In a too-alkaline mix iron and manganese lock up chemically, so the youngest leaves yellow between green veins (lime-induced chlorosis) and the plant fades out.
- Its fine, shallow roots also want an open, free-draining structure, not a heavy clay or claggy compost.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons queen pineapple struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Ordinary multipurpose or garden compost is far too alkaline for queen pineapple — expect classic yellowing, weak growth and a slow decline over a season or two.
- Hard tap water slowly pushes the pH up too, undoing a good mix; rainwater is strongly preferred for watering.
- Lime, mushroom compost or wood ash anywhere near this plant is actively harmful.
Planting queen pineapple 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 queen pineapple?
This is the whole game: Queen Pineapple 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 queen pineapple; 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 queen pineapple covers the timing and technique step by step.

What is the best soil mix for queen pineapple?
3 parts ericaceous (acidic) compost : 1 part composted pine bark or pine needles : 1 part perlite or coarse grit. Queen Pineapple 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 queen pineapple?
