What Does Potassium Do For Lawns?
Potassium is an essential nutrient for your lawn’s health. Potassium, phosphorous, and nitrogen are the three elements that plants of all kinds need in order to grow properly. All of these elements are found naturally in the soil in varying amounts, but since just about every plant in the environment needs them to grow, they can easily be depleted. This is where fertilizer application comes in handy.
Plant Health Benefits of Potassium Fertilizer
Potassium isn’t just beneficial for lawns; it’s absolutely necessary for healthy growth. Using fertilizer high in potassium has the following benefits:
- It helps the plant’s cells stay sturdy, which increases its tolerance for cold and drought, and increases its disease resistance.
- It promotes new growth in plant leaves and roots. Healthy leaves will grow faster, capture more light, and process nutrients more efficiently.
Before you pile on the potassium, though, keep in mind that every fertilizer comes with a different mix of potassium, nitrogen, and phosphorus; it’s important to find the right combination when you’re looking at potassium for your grass.
How Do I Know if My Plants Need Fertilizer?
Plants need food just like any other living thing. Fertilizer gives your lawn the nutrients it needs which may have been depleted from your soil. There are a few signs to look out for, and an ideal time to supplement your soil’s nutrient levels.
Signs of Potassium Deficiency
There are a few visual signs that your lawn could use more potassium, but sometimes the lawn looks just fine. You should be on the lookout for the following:
- Yellowing or browning grass leaves. Since potassium is important for regulating plants’ water usage, a deficiency can cause the leaves to die.
- Slow growth. Potassium also helps with photosynthesis, and a deficiency makes this process much less efficient – causing the grass to grow slower.
- Soil analysis. Your lawn may not show any signs of potassium deficiency; the only way to know for sure is to have your soil’s nutrient levels checked by a lawn care expert.

Can You Have Too Much Potassium in Your Grass?
An excessive amount of potassium isn’t harmful to your plants in itself, but since most fertilizers come with a mix of potassium and several other nutrients, it’s important to remember that fertilizer can be harmful to your plants and the surrounding environment if used in excess.
Also, remember that too much of a good thing can be a bad thing; potassium encourages new growth, which can harm the plants if it occurs at the wrong time. New growth is delicate, and if it emerges just before excessive sun or excessive cold, it isn’t as well-equipped to handle it as a mature plant.
When to Fertilize Your Lawn
Potassium for grass is best applied in early fall. This is because potassium can help strengthen your lawn, giving it a little extra help standing up to the chill of winter. However, plants may need fertilizer at any time of the year!
