Overview

• Brand : Lawn Synergy
• Item Form : Granules
• Liquid Volume : 720 fluid ounces
• Specific Uses For Product : Plant Growth, Root Development, Seed Development
• A balanced 15-20-10 starter fertilizer designed to support early root development and healthy establishment in new or renovated lawns. Blended with slow-release nitrogen, ammonium sulfate, and micronutrients to provide steady, reliable feeding during the first stages of growth.
• XCU slow-release fertilizer provides gradual, steady nutritional uptake for up to 10 weeks of plant response. XCU fertilizer has the highest nitrogen (N) content (43%) and lowest sulfur content (4%) of any polymer-coated sulfur-coated urea (PCSCU) on the market. The value is more area can be covered per application using less fertilizer, which is more efficient and economical. Also, with less N lock-off more of the applied N is taken up and utilized by turfgrass or plants in the expected time frame.
• Soil moisture penetrates the sulfur and polymer coatings.
• Nitrogen begins to dissolve creating pressure within the granule.
• After N release, the sulfur eventually breaks down into the soil where it may be taken up by the plant.
• Provides the essential phosphorus and early nitrogen balance that young grass needs to develop deep, vigorous roots during establishment.
• A dual-source nitrogen blend
• This combination provides consistent growth during the first critical weeks.
• Includes key micros that help young turf handle stress, color up evenly, and develop properly during its first season.
• Apply our 15-20-10 Starter Fertilizer evenly using a broadcast or rotary spreader at the recommended rate on the bag. For new seed or overseeding, apply before or immediately after seeding. Lightly water after application to help the nutrients move into the soil and support early root development. Safe for all turf types when used as directed.
