Rosemary in a Zone 6 season

Zone 6 gives about 179 frost-free days. Rosemary needs roughly 120 days from transplant. That leaves about 59 days of slack, enough for one full crop with a little room for a cold spring.

How to grow rosemary

Plant a nursery transplant in full sun and sharp drainage. In rainy climates set it on a mound or in a pot so water drains away. Tender: where winters freeze, grow it in a pot and bring it in for the cold months.
