Rosemary

Cultivation and Propagation, you can only leave rosemary out all year long if you live in a zone 8 to 10. The two reasons people lose their rosemary in the winter are incorrect watering and too heavy a soil. Judicious watering is imperative. It hates wet feet and will surely die if left un-watered for too long. It doesn't like being near a hot sunny window in summer where it will burn. If you are growing it in a container, consider taking it out of the pot and putting it in the garden for the summer where it can wiggle its toes. You will get much more vigorous growth and a healthier plant to survive the winter indoors. When you do repot it, nice, loose soil mixed with perlite, sand, and vermiculite is a must.
