Transplant outside when all danger of frost has passed. Space plants 12″ apart, in rows at least 12″ apart in well-drained but relatively poor soil in a location that receives full sun to partial shade. Once plants are established they will require little care. To avoid legginess, pinch off growing tips to make a bushier plant. Plant height 6”.
Thyme plants are susceptible to fungal diseases, avoid over watering. Wetting their leaves, while watering, also reduces their fragrance. Once established it is a drought tolerant groundcover. Deer and rabbit resistant.
To keep plants from becoming too woody, cut back plants by one half after flowering, to encourage new growth. To overwinter – keep sheltered from cold winds by mulching. In climates where the temperatures regularly go below 10 degrees F, plants should be heavily mulched or potted and brought inside during the winter months.
Thyme, Lime thymus x citriodorus ‘Lime’
Lime Thyme, a perennial, has citrus overtones but is not overwhelmingly lime-scented. It does not work well as a culinary herb. Rather, the bright emerald color of the foliage is reminiscent of summer limes. This, coupled with its low, even growth habit, makes it a gorgeous ground cover.
It works well in combination planters, with other herbs or flowers, and also with thymes of different colors. In the summer, Lime Thyme bears pink flowers. Honeybees love the flowers of the thyme plant!
