About Toe toe
Cortaderia richardii · also called Toe toe, Toetoe · flowering
Cortaderia richardii is a large, clump-forming evergreen grass native to New Zealand. It thrives in full sun with moist, well-drained soil and is more compact and graceful than South American pampas grass. Striking arching plumes appear in late summer. Highly tolerant of coastal conditions, wind, and a range of soil types once established.
Preferred mix: Moist, well-drained loam to sandy loam; pH 5.5–6.5
Watch for — Crown rot: Prolonged waterlogging, especially in winter, can cause the crown to rot. Plant in well-drained soil and avoid cutting back too hard in autumn, as dead foliage protects the crown from frost.
Why toe toe needs this mix
Toe toe flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for toe toe: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons toe toe struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives toe toe weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving toe toe in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for toe toe?
Most flowering plants, including toe toe, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
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
A quality bagged compost works for toe toe in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for toe toe covers the timing and technique step by step.

What is the best soil mix for toe toe?
3 parts good loam or quality peat-free compost : 1 part well-rotted compost or leaf mould : 1 part grit or perlite. Flowering is expensive for toe toe: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
Can I use normal potting soil for toe toe?
A thin, hungry or sandy mix gives toe toe weak growth and few, short-lived flowers — it simply runs out of fuel. A quality bagged compost works for toe toe in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
