About Walking Stick Kale

Brassica oleracea var. longata · also called walking stick kale, Jersey kale · edible

Walking stick kale, the Jersey cabbage, is a curiosity brassica that grows a tall, woody single stem 1.5-3 m high, traditionally dried and varnished into walking canes. Its young leaves are edible like ordinary kale and were historically used as cattle fodder. A long-season biennial, it needs a full growing year, firm staking and a sheltered, fertile site to reach its towering, top-heavy height.

Preferred mix: Deep, rich, firm, well-drained loam

Watch for — Wind rock and toppling: The tall, top-heavy stem easily blows over and loosens its roots. Plant very firmly in a sheltered spot, earth up the base, and stake the stem securely as it grows.

Why walking stick kale needs this mix

Walking Stick Kale is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.

What goes wrong with the wrong mix

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

Under-feeding and inconsistent moisture. Walking Stick Kale needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.

pH — does it matter for walking stick kale?

Walking Stick Kale 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 walking stick kale 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.

Walking Stick Kale 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 walking stick kale covers the timing and technique step by step.
