How to Grow Tobacco, and other Nicotiana Plants in your Garden

Tobacco is a very easy plant to grow and look after, the seeds should be sown on the soil surface following the last frost of spring.

They are able to grow in lightly shaded or partially shaded areas and grow in most soils. For best results grow tobacco in a slightly acidic soil.

Tobacco can be grown indoors first. The seeds germinate in the light at 20 to 25 degrees Centigrade (68 to 77°F). This should take about two weeks.

Allow the seedlings to grow for about five weeks. Then transplant the tobacco plants into the garden following the last frost. Space at about 45 cm (18 inches) apart.

Caring for Tobacco plants

Once growing, tobacco should be watered during prolonged dry periods. Removing their trumpet flowers before they start setting seed will encourage further flowers. It is best to grow Nicotiana species from seed if you require further plants.
