Instructions for growing in pots (recommended):
Leave the plant outside between May and October but bring it inside between October and the end of April, until the spring frosts are over. Place in a warm place on your land protected from the winds and place in full sun. Enlarge the pot every 2 years as needed depending on growth and add fertilizer of your choice as needed. Can easily withstand a semi-dormant winter period in a cool place between 8° and 14°C... Ex: semi-heated garage. Finally...Remember to acclimatize your plant to the sun in spring by not placing it directly in full sun for the first few days but going there gradually otherwise the leaves will burn in the sun in a few days.
