What trees and shrubs are these spikes designed for?
These spikes are formulated specifically for northern trees and shrubs ? such as maple, birch, oak, dogwood, and boxwood ? that commonly suffer from iron, manganese, and sulfur deficiencies.
What is the nutrient formula?
The 8-10-10 formula contains: Nitrogen (8%), Phosphate (10%), Potash (10%), Sulfur (4.8%), Iron (3.3%), and Manganese (3.2%). The balanced blend supports leaf, root, and overall plant health.
How long does one application last?
Each spike uses a slow-release formula that feeds continuously for up to 12 months, so you only need to apply once per year.
How do I apply the spikes?
Simply insert the spikes into the soil near the root zone of trees or shrubs ? no measuring, mixing, or special tools required.
How many spikes do I use per tree?
The number of spikes depends on the size of the tree. Refer to the package label for guidance based on your tree's trunk diameter or drip line size.
How close to the trunk should I insert the spikes?
Place spikes near the root zone (dripline area), not directly against the trunk, to ensure nutrients reach active roots effectively.
Will these spikes burn my trees or over-fertilize them?
The slow-release design minimizes the risk of over-fertilization, making them safe for gardeners of all experience levels.
Are these spikes safe for pets and children?
Keep out of reach of children and pets. Always wear gloves when handling, and store in a cool, dry place away from heat sources.
Can I use these on acid-loving plants?
Yes ? the elemental sulfur (4.8%) helps lower soil pH, which enhances the uptake of iron and manganese, making these spikes well-suited for acid-loving trees and shrubs.
Are these organic?
The product is listed with an organic special feature, but always check the label or contact the manufacturer for full organic certification details.
How are these different from Lutz Palm Spikes?
The non-Palm (Perfect Tree) formula uses an 8-10-10 blend with nitrogen, phosphate, potash, sulfur, iron, and manganese for northern trees and shrubs. The Palm formula contains nutrients specifically blended for palms and ferns.
Can these be used year-round?
Yes ? because each spike lasts up to 12 months, a single annual application is sufficient. Best applied at the start of the growing season.
Do these work in all soil types?
These spikes are designed to deliver nutrients directly to the root zone regardless of soil type, though they work especially well in soils where pH adjustment is needed for nutrient uptake.
What makes Lutz spikes different from brands like Jobe's or Miracle-Gro?
Lutz spikes offer a 12-month continuous feed (vs. seasonal reapplication every 3?6 months for Jobe's or Miracle-Gro), include iron and manganese to combat northern tree deficiencies, and feature an 8-10-10 formula with sulfur for specific tree types.
Where can I buy more or get a larger pack?
The spikes come in a 40-count pack and are available on Amazon. A 125-count pack is also available for the Palm formula.
