Kumquat trees typically die from improper watering, nutrients, or climate. However, transplant shock, pests, and disease can also affect them. For best results, water only when the soil is dry, apply compost, and plant in USDA hardiness zones 9-11. Once the source of stress is reduced, the kumquat tree should recover.
