Choose a spreader based on the size of the area, the level of control required, and the type of material being applied. Larger, open lawn or turf areas are better suited to rotary spreaders, which cover ground efficiently. Smaller or more defined areas benefit from drop spreaders, where control and accuracy matter more. Handheld spreaders are best for spot treatments, edging, and small or awkward spaces.

A rotary spreader distributes material in a wide arc using a spinning disc, making it efficient for covering larger areas quickly. A drop spreader releases material directly beneath the hopper in a controlled band, which is better for precise application along edges, borders, or narrow areas. The choice depends on whether coverage speed or control is the priority.

Calibration involves setting the spreader to deliver the correct application rate for the product being used. Start with the manufacturer’s recommended setting, then test on a small, measured area. Adjust the setting as needed until the correct amount of product is applied evenly. Calibration should be repeated whenever you change products or application rates.

Spreader settings are a guide only. Application rate can be affected by product characteristics, granule size, moisture content, walking speed, and ground conditions. For best results, settings should always be checked and adjusted through calibration rather than relied on as fixed values.

Uneven application is usually caused by inconsistent walking speed, incorrect overlap between passes, poor calibration, or product that is damp or uneven in size. Maintaining a steady pace, overlapping correctly, and using clean, free-flowing material will help reduce striping.

Some spreaders can be used for both fertilizer and seed, provided the product is compatible with the spreader design and settings. Application rates must be adjusted for each material to achieve even distribution. Always check product suitability, as not all spreaders are appropriate for all fertilizer types or coated products.
