Buying Guide

What is Organic Lawn Fertilizer?

Organic lawn fertilizer is the type of fertilizer used in organic lawn care, which prevents, controls, removes weeds, and maintains the lawn with only natural materials - no synthetic components, pesticides, or any harmful chemicals permitted.

According to House Method, organic lawn care typically mixes safe ingredients like bone meal, seaweed, feather meal, etc. to maintain and improve lawn health. Though this is usually not as effective as traditional lawn care, which often uses powerful synthetic materials & pesticides, organic lawn care is friendly and safe for family and pets.

 

Benefits of Using an Organic Lawn Fertilizer

Improve lawn aesthetics

Lawn fertilizer improves the look of lawns by improving its health, which in turn results in a greener, fuller, and thicker lawn. Organic fertilizer, compared to chemical fertilizer, gives the grass a more naturally bright green look. A well-manicured and healthy-looking lawn will be a source of pride for the owner and a source of envy amongst neighbors! In making your yard more attractive to look at, you increase your own enjoyment of your outside space, while also improving curb appeal to raise the value of your property and make it more saleable to potential buyers.

 

Reduce weeds

Lawn fertilizer strengthens the root systems of grass so that it is harder for weeds to take hold. A thicker lawn will also help to inhibit weeds from spreading, by depriving them of the space they need to grow. The result of this is a better-looking lawn with fewer weeds, which also saves the owner from spending money on weed treatments, and saves the time of applying them.

 

Increase disease and pest resistance.

A lawn that is regularly fertilized has all of the nutrients it needs to have a long term good health. This improved health makes the lawn more resistant to pests and disease, in the same way, that a healthy person with a good immune system is more resistant to illness.

 

Increase weather tolerance

Strong lawns are also better able to cope with fluctuations in the weather. Grass that is weak will easily burn and turn brown during hot summers or may die in times of drought. However, grass that is strong as a result of fertilization will have improved tolerance to these conditions. Stronger root systems also allow the grass to take in more water, which will help in times of heavy rain.

 

Safer for everyone

Organic lawn fertilizers contain no chemicals or harsh synthetic substances. This means you can use them around children and family pets without any worry that contact with the fertilizer may make them sick. Many people worry about the long term effects of spending lots of time around a chemically fed lawn, especially if children walk barefoot on the lawn, or if pets nibble on the grass, but this is not a concern with organic fertilizers which are completely safe.

 

Environmentally friendly

Garden fertilizers can leach into local waterways, harming wildlife and even ending up in our drinking water. Organic fertilizers ensure we don’t damage our environment, as they are completely safe, unlike their chemical counterparts. Some regions have rules and regulations that prevent chemical fertilizers from being used due to the harm they can cause, but organic fertilizers are excluded from this as they are completely natural and won’t put the environment in danger.

 

Resourceful

Organic fertilizers are made from naturally derived materials which may otherwise be disregarded as waste. Materials such as poultry manure, or fish bones, are utilized in natural lawn fertilizers, making a useful and beneficial product out of things that would ordinarily be wasted.

 

What to Look for in an Organic Lawn Fertilizer

What sort of results you want from a lawn fertilizer will help you decide which features are most important to you. Some factors to consider include the following.

Formula ingredients

Check the formula of organic fertilizer to see what its primary ingredients are. If you are concerned about the smell of organic fertilizer, then you should stay away from lawn feeds that are made from animal derivatives, manure, or fish products. The worst smelling fertilizers usually contain chicken manure or blood meal, but if you are not bothered by this temporary odor, then these make excellent fertilizers. You should also check the ingredients list if you are averse to using products containing animal products based on ethical grounds, for example, if you are a vegan. There are plenty of organic fertilizers available that use natural materials not derived from animals.

 

Application method

Consider which method of application is most appropriate for you and choose a fertilizer that can be applied in this way. Some lawn food can be applied by hand or in a handheld sprayer, whereas some could be hooked up to a trailer sprayer for especially large lawns.

 

Cost-effective

Organic fertilizers do tend to cost more than chemical options, but many people find this additional expenditure is worth it to have a clearer conscience. If you have a budget to stick to, you will need to know the size of your yard in order to figure out how much lawn feed you will need to fertilize all of it and decide which options suit your finances the best.

Most users highly recommend this lawn food, stating that severely burnt and dried out the grass was looking green and lush again over the course of several applications.
