Tulsi in cold countries
I would like to know if Tulsi is perennial in cold countries ( transferred indoor for over wintering). If so are there seeds for such perennial cultivar of tulsi?
Frederick County Maryland herbs
Hi- we are not aware of tulsi basil (Ocimum sanctum) surviving outdoors over the winter in Maryland. Gardeners grow it strictly as an annual, although it freely self-sows- some seeds that drop to the soil this season will germinate next spring.
Plants can be dug and potted this time of year and brought indoors. The plants will need a good light source to grow well indoors- fluorescent or LED.
Lots of informative videos and web content if you search "growing tulsi indoors."
