Tips on Choosing the Best Fertilizer
To pick out the right fertilizer for your lawn you need to be aware of the type of grass you have and how the climate affects your yard. Do some research into the type of grass and also check which pests or plant diseases are common in your area.
Once you have this info, it is time to find the best liquid fertilizer for your lawn. Regardless of where you live or what type of grass you have, here are a few things to look out for.
Nutrients
The three main fertilizer nutrients you want in the solution are nitrogen, phosphorus, and potassium. The ratio of these three nutrients is usually mentioned on the bottle as an N-P-K ratio.
Natural Ingredients
Aside from the N-P-K ration, certain organic fertilizers use natural ingredients that have beneficial properties for plant growth, strength, and health. Popular common natural ingredients are humic acid, seaweed and sources of protein from fish and seafood.
Concentrate or Ready-To-Use
Always check the instructions for how to use the liquid fertilizer. The steps will be different depending on whether the solution is a liquid lawn fertilizer concentrate that needs to be mixed with water first or one that can be sprayed directly onto your lawn.
The ready to use bottles are more practical since there are fewer steps to take. There are also bottles that you can connect to your hose so that you are watering and spraying fertilizer at the same time.
Health Hazards
Organic fertilizers are generally safer to use than chemical fertilizers because the ingredients are natural and so in most cases safe for yourself and for pets. However, always check whether this is truly the case, even when the bottle states that it only contains organic ingredients.
Frequency of Use
Each solution is different so check the instructions for how often you should spray it on your lawn. There are also different fertilizers for different stages of plant growth so check the bottle for when it is best applied.
There are all-purpose fertilizers, as well. These are great as a general fertilizer that you can use at any plant growth stage but you may want to incorporate extra nutrients at different stages.
