|You can feed your lawn in early April. 15-15-15 is sometimes called "geranium fertilizer" but it is an all purpose fertilizer and should be readily available in your garden center. "Best Triple Pro" is one brand name and it is perfectly fine to use on plants but not recommended for lawns. For lawns you'll want to use a product with a 3-1-2 ratio of NPK such as a 21-7-14. This ratio of NPK encourages green top growth, no flowering (middle number) and strong stem and root growth. Hope this answers your question.
