Lutz Ultra Citrus Fertilizer Spikes

Easy Nutrition for Thriving Citrus Trees Give your citrus trees the targeted nutrition they need to thrive with Lutz Super Citrus Fertilizer Spikes. Specially formulated for citrus varieties like lemon, lime, and orange trees, these convenient spikes deliver a balanced 8-4-8 nutrient blend along with essential micronutrients including iron, manganese, magnesium, copper, zinc, boron, and sulfur. This complete nutrient package helps address common deficiencies that can lead to yellowing leaves, weak growth, or poor fruit production—supporting healthier foliage and stronger overall tree performance. Simply insert the spikes into the soil around the root zone to feed your tree where it needs nutrients most. As they gradually dissolve underground, they release nutrients directly to feeder roots and help improve nutrient absorption by lowering soil pH in the feeding area. The slow-release formula provides steady nourishment for up to 12 months, offering a mess-free, low-maintenance way to support vigorous growth and abundant citrus harvests year after year.
