“What is the minimum temperature for growing ginger plants outdoors?” Question from Susan of Pembroke Pines, Florida
Answer: Culinary ginger (Zingiber officinale) is a true tropical plant that originates from Southeast Asia. It survives in USDA Hardiness Zones 9 to 12, which means that it can withstand outdoor cold reaching down to 25 to 30 degrees F, no colder. Temperatures on the coldest end will still stress plants out and cause their foliage to die back, so it’s best to keep them in a warm, humid location if the weather really takes a cold turn. But, ginger should grow really well in your zone 10 location under normal weather conditions.
Happy ginger growing!
