Curcuma longa is a member of the ginger family (Zingiberaceae). Its rhizomes (underground stems) are the source of a bright yellow spice and dye. Turmeric is sterile (does not produce seed, but it does grow vigorously from the rhizomes).urmeric was often hung in kitchens as a good luck charm, and a small rhizome was sometimes tied to the pots in the kitchen for luck. In Europe and the USA, turmeric is widely used as a colouring agent in processed foods, sauces, pharmaceuticals, confectionery and textile dyes.
If you have a lease with an ending date, and the ending date goes by, and you keep living there with your landlord's permission, your lease changes to a month to month lease. If you want another lease with a specific ending date (such as another 1 year lease), you must sign a new lease with the landlord.
A tenant that will not sign a new lease is a probably a red flag as it is a very simple process and unless they are planning on bolting will want to sign up again. So there are many options. Auto renewal, new lease each year or rent increase if m-m and I am sure many more creative methods to run your business.
