Description
How long will it last?
Our 16 oz. bag is perfect for feeding multiple shrubs and trees in your garden. Recommended rates may vary depending on the size of your plants and trees. Avoid placing fertilizer directly next to the stem of any plant, as this can cause damage. Instead, spread it around the "drip line" - about 4-6 inches away from the plant's stem. Be aware that different plants have different fertilizer needs, so research your plant/tree's appetite. Our customer service team can provide guidance on the approximate amount needed. Send us a message for personalized recommendations.
