4 plants per square foot in 2 rows 15 cm (6″) apart
Only just cover the seeds as they require light to sprout.
Full or partial sun and a slightly acid-to-neutral (pH 6.6-7.8) garden soil with good drainage. A rich soil will produce lush leaf growth but few flowers.
Seeds will sprout in 10-14 days
Not bothered by many pests and often recommended as a companion plant. However, when weakened by lack of water or other issues may be attacked by aphids, mealybugs or thrips.
Sow indoors 6 weeks before last expected winter frost. Plant out after last frost. Direct seed in the early spring or in the fall to overwinter.
Needs very little care once established. Like most herbs, it grows best when it is not fussed over. Too much fertilizer will result in lots of weakly flavored foliage and few flowers. Drought tolerant; water only in times of prolonged drought. Plants should be clipped or mowed to 5 cm (2″) after blooming to keep them compact.
30 days, blooms for 8 weeks
