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.
Our slow-release granular fertilizer (5-6-5) gives your tomatoes all the nutrients they need, including plenty of phosphorus for big, abundant fruit. For a healthy start, mix a handful into the soil at transplant time and then side dress when tomatoes begin to set fruit. Also ideal for peppers and eggplant. Contains peanut meal.

Fertilize your roses with greensand to prolong their blooms next year.
