Ever notice how container-grown plants seem to flourish early in the season, then start to fade by midsummer? That’s because most fertilizers are used up or leach away within the first month. Our Gardener’s Supply All-Purpose Organic Fertilizer is a slow-release, 5-5-5 granular organic fertilizer that gives plants balanced nutrients for vigorous root growth and improved water penetration all season long. Contains only naturally occurring minerals, peanut meal and animal or vegetable meal.
