Oregano – Place the fresh cuttings of oregano in water and pinch the growing tips as the herb grows.
Lemon balm – You should pick several cuttings in spring or fall, and place them in water in a bright spot. After 3-4 weeks, the cuttings will develop roots. Change the water often, or you can keep the plant outdoor if the weather is warm. You can prepare tea from the leaves.
Stevia – You can add stevia to some beverages and teas. Just place some stevia cuttings from actively growing branches in a container full of water, and keep it in a sunny and warm place.
