Proudly Made in the USA TreeHelp Premium Fertilizer: Redbud is a slow-release fertilizer for a species where TreeHelp's own care guide recommends slow-release nitrogen specifically to help manage Verticillium wilt, a disease that causes yellowing and then browning of leaves at the ends of branches. It feeds a redbud steadily through the growing season instead of in one quick burst, while guarding against the weak growth that leaves it more vulnerable to problems like scale insects and dieback, the most destructive disease that attacks redbud trees. Benefits Promotes root development and disease resistance: The macro and micronutrient mix in TreeHelp Premium Fertilizer supports root development and disease resistance, which matters for redbuds given their vulnerability to dieback, the most destructive disease that attacks the species, along with leaf spot problems. Why slow-release nitrogen matters for redbuds: Quick-release nitrogen pushes weak, elongated growth and stretched cell walls, which can spread vascular wilt diseases like Verticillium wilt and make a redbud more attractive to pests like scale insects and tree hoppers, as well as more vulnerable to wind or cold damage. TreeHelp Premium Fertilizer avoids that by releasing nitrogen gradually instead of all at once, matching TreeHelp's own recommendation of slow-release nitrogen for managing Verticillium wilt in redbuds. Long-lasting, full-season feeding: One application keeps feeding a redbud throughout the entire growing season instead of needing repeat treatments. Custom-matched, high-quality formula: Made with top-quality ingredients in a blend formulated specifically for redbuds rather than a generic, one-size-fits-all mix. Suited to how redbuds grow: Redbuds grow best in moist soil with full sun to shade, reaching about 30 feet tall with a 25-foot spread at a rate of 12 to 18 inches a year. TreeHelp Premium Fertilizer's macro- and micronutrient mix supports the root development a redbud needs to establish well.
