The Lawnifi Spring Fertilizer Box is perfect for spring lawn care. Apply one application of Maintain at the start of spring to promote healthy roots and the return of green leaf blades after winter dormancy. In mid-spring, apply Boost to deepen the green appearance of your lawn. Boost will deliver greening benefits to your lawn immediately, and long into the season because of its time-release formula. In late spring, use the remaining bottle of Maintain to prep your lawn for the heat and stress of summer. Our patented nano-fertilizers with Catalyst Technology give your lawn the jump-start it needs to emerge from dormancy, green up fast, and thrive throughout the spring months. Throughout the seasons, the nutritional needs of your lawn vary as temperatures, soil conditions, and other environmental demands change. Please refer to the application schedule below. Coverage: Each bottle of the Lawnifi Spring Fertilizer Box will cover 5,000 square feet. So the entire box is meant to help a lawn of around 5,000 sq ft thrive throughout the Spring. APPLICATION SCHEDULE Make the first application of MAINTAIN any time in the first few weeks of spring. Apply the second application of BOOST four weeks following your initial application. Four weeks following your last application, apply MAINTAIN before beginning your summer fertilizer maintenance program. Maintain SDS Maintain Label Boost SDS Boost Label When and How to Apply the Lawnifi Spring Fertilizer Box Apply Maintain, the first bottle of the Lawnifi Spring Fertilizer Box, at the beginning of spring. “Beginning of spring” looks different depending on where you live. For best results, apply Maintain when spring green-up begins and your lawn is transitioning out of winter dormancy. From there: Apply Boost 4 weeks after Maintain to deepen the green appearance of your lawn Apply the second bottle of Maintain 4 weeks after Boost to help your lawn prepare for warmer temperatures and summer stress. Use the chart below to help identify the right timing for your region. Important Tips: Space all applications at least 4 weeks apart. Apply the first Maintain when soil temps begin climbing into the 55–60°F range and you see signs of green-up. Avoid fertilizing before grass actively greens, as nutrients won’t be effectively absorbed.
