A spike format for tree and shrub feeding

Jobe’s Slow Release Tree and Shrub Fertilizer Spikes come in a 15 count package for seasonal landscape feeding. The spike format gives the task a clear shape: read the label, find the dripline, place the spike, and record the date.

That kind of routine suits gardeners who keep a simple care calendar for trees, shrubs, and ornamental edges.

Let the label guide placement

Tree and shrub feeding depends on plant type, season, soil moisture, and root area. The package directions should guide spacing, timing, and depth before any spike goes into the ground.

Keep the feed step separate from the first plain-water establishment routine for new plantings unless the plant-care plan calls for feeding.

Store spikes with landscape notes

Fertilizer spikes stay organized when the package, mallet, gloves, and feeding notes stay together. A dated tag or card can record which tree or shrub received a feeding pass.

Store the package dry and closed between sessions.
