Simply hammer it into the soil and let it begin feeding your plants. Rest assured, it will not break, crush, or get smashed.

The nutrient-rich formula of our fertilizer spikes consists of 13-3-3, which means it contains 13% Nitrogen for vibrant and colorful plants, 3% Phosphorus for abundant fruiting and blooming, and 3% Potassium for strong and healthy roots.

One of the benefits of using The Old Farmer's Almanac Fertilizer Spikes is that there is no waste or runoff. The spikes release the nutrients directly into the root zone where the plants need them most, promoting stronger and healthier trees and shrubs without any waste or environmental harm.

Using our fertilizer spikes is simple. For optimal results, it is recommended to fertilize your plants twice a year, ideally in early spring and late fall, to ensure continuous nourishment. Depending on your climate and plant variety, an additional application in the summer can provide extra nutrition and help protect your plants from the stress of summer conditions.
