About Amaryllis 'Red Lion'
Hippeastrum 'Red Lion' · also called Red Amaryllis · flowering
'Red Lion' is the classic deep-red amaryllis, sending up a tall hollow stalk topped with two to four large velvety trumpet flowers from a single fat bulb. Easy to force indoors in winter, it wants bright light, a snug pot, sparing water until growth starts, and a dry dormancy to rebloom.
Preferred mix: Rich, free-draining potting mix
Watch for — Bulb rot: Burying the bulb fully or overwatering before roots form rots the basal plate; plant with the top third exposed and water sparingly until growth begins.
Why amaryllis 'red lion' needs this mix
Amaryllis 'Red Lion' 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 amaryllis 'red lion': 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 amaryllis 'red lion' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives amaryllis 'red lion' 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 amaryllis 'red lion' 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 amaryllis 'red lion'?
Most flowering plants, including amaryllis 'red lion', 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 amaryllis 'red lion' 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 amaryllis 'red lion' covers the timing and technique step by step.
