Kale + Thyme

Kale and thyme are a practical pairing for cool-season beds. Thyme deters cabbage moths, one of the more persistent threats to brassicas, and its flowers attract predatory wasps and hoverflies that keep aphid pressure in check. Both crops tolerate light frost and continue growing into late fall, which means a single bed can support both through spring and autumn seasons before the kale is replaced.

Spacing works in their favor: thyme is low-growing and spreads laterally without shading the kale canopy. Plant thyme at the bed edges or between rows, leaving 12 to 18 inches between plants. Both tolerate average, well-drained soil with similar pH preferences (6.0 to 7.5), so no soil amendments are needed to accommodate one at the expense of the other.

The pairing is less useful in midsummer plantings, as thyme goes semi-dormant in heat and kale bolts. Plan for spring or fall establishment to get full benefit from the insect-repellent effect when brassica pest pressure peaks.
