Habanero peppers are not only packed with capsaicin and capsaicinoid antioxidants, but also other useful plant-based elements such as flavonoids and carotenoids. These powerful phytonutrients work in synergy to decrease insulin resistance, improve pancreatic activity and prevent sudden spikes in blood sugar levels. Two important growing tips for habanero peppers are infrequent but deep watering. Row covers are often necessary with habanero care to avoid sunscald and to keep peppers from drying out and cracking. Fertilize the plants with ¼ tablespoon of nitrogen per plant when habanero plants are at least six weeks old.
