Buying Guide


There are a lot of choices for fertilizers out in the market. The options that are available for your plant are organic and non-organic fertilizer. We prefer organic fertilizers because they are not made of petroleum products and they do not harm the soil in the long-term. 

Firstly, consider the type of soil you have in your backyard. Is it clay, loam, or sand? Loam is considered the holy grail of soil types. Sometimes the soil is a combination of these three types. Sandy soil is great with drainage but it does not hold the nutrients in it. The clay soil is fertile but it has drainage issues. So, look for the fertilizer that is suitable for the type of soil in your backyard.

Now, you need to know that what is your soil missing in it. The best way is to use the basic soil test. It does not cost you much with it will help you to know the needed nutrients. Organic fertilizers are labeled with the percentage concentration of nutrients. They come with an NPK ratio in a formula of 6-12-0 which means that 6% is Nitrogen, 12% is Phosphorous, and 0% Potassium. 

The other factor that you need to consider is that the fertilizers come in dry and liquid forms. Dry fertilizers are slow to release but they last longer than liquid fertilizers. Dry fertilizers are best recommended for general plant maintenance and rebuilding the nutrients directly into the soil. The liquid fertilizers act faster than dry fertilizers. 

Liquid fertilizers are best when you need a boost for your plant. They are helpful in the conditions where there is a lot of heat and optimum water, the liquid fertilizer blooms the plants and veggies in a shorter period.
