Slow Release Spikes - Jobe's Tree & Shrub Spikes 15-3-3, 5 Pack | Deep Root Plant Food

Establishing massive shade trees and thick privacy hedges requires a highly concentrated, long-lasting source of deep nitrogen. These Jobe's Tree & Shrub spikes serve as an exceptionally convenient fertilizer for plants, delivering a powerful 15-3-3 vegetative boost exactly where the heavy feeder roots live. You can effortlessly push your young saplings and established bushes to produce incredibly dense, vibrant green foliage with a single, mess-free application.

Expertly compacted into durable stakes, this slow-release plant food completely bypasses competing surface weeds and lawn grass, delivering raw energy directly beneath the topsoil. When you drive these highly concentrated spikes into the moist earth, they begin a steady, months-long breakdown process governed by natural soil bacteria. This constant, underground feed prevents the sudden, weak flush of leggy growth that often occurs when using a fast-acting liquid fertilizer, instead encouraging robust, structurally sound branches that can easily withstand heavy winter snow loads. It is a highly reliable, set-it-and-forget-it nutritional strategy for maintaining a lush, perfectly manicured landscape.

Use a rubber mallet to safely pound these spikes into the ground along the drip line of your deciduous trees, fast-growing maples, and thick privacy cedars twice a year¡ªonce in early spring and once in late fall. Always space them evenly to ensure the entire expanding root mass receives adequate nutrition. This 5-pack of pre-measured spikes from Jobe's provides homeowners with an incredibly clean, highly effective, and deeply penetrating solution for serious landscape management.

Store in a cool, dry place away from direct sunlight and moisture. Reseal packaging tightly after use to maintain product quality and effectiveness.
