Since it can’t burn the grass, many people wonder how often can you apply Milorganite to your lawn? To determine the answer to this question, let’s first go over the general application guidelines from Milorganite themselves.

General Guidelines For Milorganite Application
The general recommendation is to apply Milorganite to your lawn four times per year, spaced about 8 to 10 weeks apart per application.
Here’s a basic Milorganite fertilizer application chart:
| Season | Recommended Application Time | Purpose |
|---|---|---|
| Early Spring | March to April | Helps lawn recover from winter dormancy |
| Late Spring | May to June | Boosts growth during active growing season |
| Late Summer | August to early September | Helps recover from summer heat and promotes fall growth |
| Fall | October to November | Prepares lawn for winter dormancy |
This chart essentially breaks down the cool grass active-growing period into four seasons, each providing a scheduling window to apply Milorganite to your lawn.
Factors To Consider Before Applying
While the recommended application schedule above makes sense, there are some other factors to consider when deciding how often to apply Milorganite to your lawn:
Grass Type: Cool-season grasses like Tall Fescue, Kentucky Bluegrass, or Ryegrass prefer organic fertilizers in the spring and fall. Warm-season grasses like Bermuda and Zoysia benefit the most from Milorganite applications during the active-growing season (late spring through summer).
Soil Conditions: Like any fertilizer, if you use too much of it, you can create a nutrient imbalance. While this is more difficult to produce using an organic fertilizer like Milorganite, it is still a good idea to get your soil tested to find out what your soil may be lacking.

Climate: In cooler climates, you’ll want to apply Milorganite less often as the organic fertilizer will not be able to break down as quickly. In warmer climates, you can apply more often as the nutrients will be able to break down faster.
Overseeding: Using Milorganite as a binder when pregerminating grass seed can be a great way to make it easier to spread when overseeding your lawn in the fall.
Apply The Amount of Milorganite That Works For You
While the recommendation is to apply Milorganite about four times per active-growing period, you can apply more or less than this recommendation based on the factors listed above.
Since Milorganite is an organic fertilizer, there is a very low risk that you’ll hurt your lawn in any serious way which is why this fertilizer is one of the most popular organic lawn fertilizers on the market today.
