STA Green Spreader Settings: Optimum Settings For Different Products

A STA Green Spreader is a great way to spread Fertilizer in the garden.  It offers multiple spreading options depending on the users requirements. But , which settings should you use in your STA Green Spreader for these products for a productive result?

There are multiple ways you can apply the STA Green Spreader settings. On average, you can choose 1.5-1.75 for drop and 4-4.5 for rotary STA Spreaders. These settings depend entirely upon the spreader type and the product size. But, it is always recommended to calibrate the spreader for optimum settings.

It will take a lot of time to manually search and determine the settings for your STA Green spreader. Read this article, and you will get all the important criteria and settings applicable to your spreader compatible with the most widely used products.

STA Green Spreader Settings

If you have an STA Green spreader and a lawn that needs to be fed, you must determine the most compatible settings. It is an important step before feeding your lawn because the settings determine how much product the spreader drops in a unit area.

The rate of flow either can damage or present you with a greener, soft lawn. It is because overfeeding your lawn with products damages the grass by burning it. This happens especially while using synthetic fertilizers or insecticides.

Moreover, underfeeding will not show any visible result, and hence that would waste the product. There are two crucial factors you should take into account before applying settings on your STA Green Spreader.

Considering Product Type Before Setting

STA Green Spreader is compatible to work with most feeds and fertilizers available for lawns and yards. But you cannot use a single setting while working with different products. It is because the size of the prills or particles in the products acts differently on the flow rate.

That is why it is better to inspect the prill size while determining the settings visually. Bigger prill sizes require higher settings as the particles could accumulate on the drop hole and do not allow other particles to pass.

Again, a very small prill size requires a small drop hole. Working with bigger drop holes will result in overfeeding and product wastage.

STA Green Spreader Type

There are two major types of STA Green Spreaders. These are the rotary or broadcast and drop spreaders. The working principles of these spreaders are different, and so are the settings.

A rotary STA Green Spreader is used in lawns with an area of more than 5000 square feet. However, it is not a hard and fast rule to use bigger-sized lawns.

But it requires the product to spread around a specific area, also known as swath width. That is why higher settings are required in the rotary or broadcast STA Green Spreaders. Usually, this type of spreader requires 4-5 dial settings for different products.

Sometimes it can be as high as nine if the prill size is very big. On the contrary, a drop spreader simply lets the products fall through the drop hole at a certain rate while you walk on the lawn.

Hence, it needs lower flow rate settings compared with the rotary spreaders. The most common setting for drop spreaders is 1.5. It can go up to 2.5 for some products.

Considering Walking Speed

Sometimes, people fail to consider the walking speed while adjusting the settings in the STA green spreader. But it plays an important role in spreading fertilizers in an optimum way.

The settings on the spreader and the user’s walking speed are directly proportional. This means you need to increase the settings if you walk more than three mph and vice versa.

All products come with recommended spreader settings which are given by taking the walking speed as three mph as standard. Common settings at three mph are 1.5 for drop spreaders and 4-4.5 for rotary spreaders.

Considering Lawn Type Before Application

The lawn type impacts the optimum settings for the fertilizer spreaders. Sta-green spreader settings for overseeding lawns should be according to the above chart.

But for new lawns, you need to use more products in a specific area. Hence, you need to increase the settings of your STA Green spreader after calibrating it for a higher volume of products.

Frequently Asked Questions (FAQs)

What do the settings on a lawn spreader mean?

Every lawn spreader comes with a drop hole through which the particles of the fertilizers and feeds fall on the ground. The area of the drop hole is covered with a lid which the settings on the spreader can regulate.
Mostly, a dial setting controls the opening area of the drop hole. When you pull the lever, the lid uncovers the drop hole to let a specific amount of product to the ground. This mechanism is known as spreader settings.

What setting do I put my spreader on for grass seed?

For an overseeding lawn, you can set sta green spreader settings for grass seed at 4.5 -5 on different rotary spreaders. New lawns require 7 in the settings. Drop spreaders can be tuned at 3.5-4 for overseeding lawns and 5 for newly established lawns.

How many times should I fertilize my lawn?

Depending on the region’s climate, you can fertilize your lawns 4-6 times a year. Warm regions require 3-4 times fertilization a year, whereas cold regions require 5-6 times fertilization or more if required. Extra fertilization can be done in late spring or late fall if necessary.


Choosing the best settings on your STA Green spreader presents you with beautiful, equalized greenery and a healthy lawn. Moreover, it saves your product by distributing it equally.
