About Britton Perilla
Perilla frutescens 'Britton' · also called Britton Perilla, Shiso · edible
Britton Perilla is a compact, upright cultivar of shiso with deeply ruffled, dark-green to bronze-tinged leaves and a spicy, anise-mint flavor. Ideal for edible gardens and containers, it thrives in full sun to part shade with regular moisture. A fast-growing annual herb used widely in Asian cuisine, it self-seeds readily in warm climates.
Preferred mix: Rich, well-draining loam
Watch for — Damping off in seedlings: Overly wet, cool conditions at germination encourage fungal damping off. Sow in well-draining seed compost, thin promptly, and ensure good air circulation.
Why britton perilla needs this mix
Britton Perilla is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Britton Perilla grows fast and has a big crop to fill, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons britton perilla struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves britton perilla — growth stalls, leaves pale, and yields collapse.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Britton Perilla needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for britton perilla?
Britton Perilla does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
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
For containers a good multipurpose or vegetable compost works for britton perilla with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.
Drainage and the pot
Rich but free-draining is the target: raised beds and large containers both deliver it. Mulch heavily to even out moisture and roughly halve how often you water.
Britton Perilla is usually grown for a single season, so "repotting" means starting fresh each year — never reuse exhausted, disease-prone compost for the same crop family. When the time comes, our repotting guide for britton perilla covers the timing and technique step by step.
