The Best Milorganite Alternatives for Your Lawn Buying Guide

If you’d like some more information before selecting your milorganite alternative (or you simply fancy turning yourself into an organic fertilizer expert), keep reading to learn more about what to keep in mind when making a selection, as well as the advantages of using an organic fertilizer:

Basic features your milorganite alternative should have:

  • The organic fertilizer you select should be slow-releasing (we’ll explain why below!)
  • Keep an eye out for fertilizers with a high nitrogen content
  • It won’t overfeed your plants, which could lead to them getting burned
  • If you would like a more vibrant, green lawn, ensure that the fertilizer has a high iron content
  • It should be free from harsh chemicals

Benefits of organic fertilizer:

As there are so many synthetic garden fertilizers on the market, you might find yourself wondering if it’s really all that important to use organic fertilizers instead, right? After all, if it’s going to make your garden grow, what’s the problem? Well, when it comes to synthetic chemical fertilizers, though they may do the job in the short term, they can actually be pretty damaging in the long run. Organic gardening, on the other hand, focuses on the overall health of the soil and, though results may take longer, it’s worth the wait and ensures a flourishing garden that will last.

Organic fertilizers do take a while to start working. This is because, in order for organic fertilizers to be effective, the soil needs to first break it down. By doing so, the soil is able to regulate the amount of nutrition that it gets fed. Though synthetic fertilizers will get to work immediately (as the chemicals are powerful enough to permeate the soil) this often leads to the plant getting overfed, damaging them, and leaving them burned. 

With all that being said, here are some of the top benefits of using organic fertilizers:

Organic ​fertilizers ​help to ​improve ​soil ​health ​over ​time:

Organic fertilizers are not just good for plants, they’re also good for the soil. They allow the soil to hold water longer,  increase the bacterial activity in the soil (the good kind) and deliver plenty of nourishing nutrients to create the perfect environment for the growth of whatever has been planted within it. 

On the other hand, synthetic fertilizers are a little different. Though they offer short term effects, they actually deplete the soil of its nutrients, which in turn makes it more difficult to grow anything of substance from it. 

Organic ​fertilizers are ​safer ​than ​synthetic ​fertilizers:

When you select an organic fertilizer, you also select the peace of mind! When using one, you can rest assured that not only are organic fertilizers safe for the environment, but they are also safer for your family, and your pets. 

If you use synthetic fertilizers and care about the environment, you might want to swap it out for an organic choice. Synthetic fertilizers require a significant amount of fossil fuels to produce and process and can often runoff into nearby water sources like streams and lakes, which contributes to the world’s carbon footprint. 

In general, organic fertilizers are just a lot more ‘kinder’ to use. They reduce the risk of plants getting burned, nourish the soil, and are a much more environmentally-conscious selection.

Organic ​fertilizers are ​easy ​to ​use:

Don’t be put off from choosing an organic fertilizer if you think that they might be more difficult to use! Organic fertilizers are just as easy to apply as synthetic fertilizers and completely minimize the chances of your plants getting burned. Whether you add them to your soil or you want to spray them on leaves, they add countless benefits to your garden, all the while providing the same amount of convenience and ease as chemical fertilizers.
