Lawn Fertilizer Buying Guide & FAQ
How We Chose Our Selection Of Lawn Fertilizers
Brand –When it comes to lawn food, we wanted to make sure that the results will be the lush and green lawn you had hoped for. This is why we decided to stick to brands that have a good reputation for manufacturing products that work like promised while sticking to the ingredients listed on their packaging – to ensure that no toxic substances are used without the necessary caution given.
Price –When it comes to determining the price of lawn fertilizer, then giving accurate calculations becomes a bit tricky. But don’t worry, we did the math for you! We measured the price against quantity, quality, and the number of applications you get per purchase and then created a comprehensive list of products that will meet an assortment of different budget types.
Reviews –What better way to get the gist of a product than by getting feedback straight from the horse’s mouth. The horse we refer to in this instance is the consumer! We took some good time to read through online reviews to see if each brand of lawn fertilizer is living up to expectations. This process helped us to pluck out the rotten apples, leaving us with a selection of premium fertilizer blends that truly do work.
Features To Look For In Lawn Fertilizer
Release Type –Categorised into two types, lawn fertilizer can either have fast releasing properties or slow releasing properties. Liquid fertilizers remain instant in their effects while granular makes can release nutrients both instantly or over time. Brands that feed lawns over time are great for homeowners who prefer to stretch the months in between applications. They are also gentler and do not tend to burn grass as easily.
Consistency –Fertilizers come in two different forms, namely liquid and granular. Granular lawn fertilizers are popular for their ease of use and longevity. They can be the slow release type or can give faster results. Granular types also tend to be the cheaper option. Liquid fertilizer does not give a slow release option but the advantage is that their effects are almost immediate.
Fertilizer Numbers – Written clearly on the packaging of most fertilizer brands, you will see a list of the macronutrient levels. These levels are listed as a series of three numbers, for example, 22-5-10. The numbers give you an indication of how much nitrogen, phosphorus, and potassium (abbreviated N-P-K) is found in the granules or liquid. These are the three primary nutrients that grass depends upon to grow.
- Nitrogen –The first number printed onto the packaging indicates nitrogen. Nitrogen stimulates leafy green growth as well as growth in stems and branches. If you want lush and healthy green grass then your fertilizer should include nitrogen.
- Phosphorus – The next number listed refers to phosphorus. Phosphorus encourages seed germination and root growth.
- Potassium –Potassium is the third number listed. It plays a vital role in nutrient transportation, root growth, and disease-resistance. It also encourages Nitrogen to be used by the plants more effectively.
Kid and Pet Friendly –If you have kids or pets who play out on the lawn frequently, then we suggest you invest in a safer and non-toxic fertilizing solution. Many manufacturers realise that most homes do have children and pets and take their safety into consideration by creating non-toxic fertilizers that are organic in nature. Please read the bag for insight on how harmful the contents of each brand can be before making your purchase.
Different Types Of Fertilizer
Natural Organic Fertilizers –Organic fertilizers are made from once living organisms and their by-products. They are applied like other fertilizers but can take longer to work. This is because a natural fertilizer solution breaks down slowly and releases the nitrogen over time. While this type is safe for homes where there are kids and pets, it does emanate a strong and foul odour – mostly because manure is an ingredient.
Synthetic Fertilizers – Synthetic fertilizers have been chemically manufactured. The advantage of using this type of fertilizer is that it has the potential to make lawn grass greener by dissolving into the soil faster and immediately releasing the nutrients. The disadvantage of synthetic brands, however, is that the results don’t last very long, so applications need to be redone more often. They can also burn your lawn if not applied in a proper manner.
Lawn Fertilizer FAQ
Q: How Often Do I Need to Fertilize My Lawn?
A: How often you feed your lawn depends on the grass type and your climate. Essentially, there are two main grass types, namely cool season and warm season grasses.
- Cool-season grasses. Cool-season grasses tend to remain green throughout the seasons when grown in cooler areas. Such grasses do best in climates where winters are cold and summers remain moderately warm (but not hot). A rule of thumb is to feed cool-season grasses twice in autumn and then again in the spring - after the first flush of growth.
- Warm-season grasses. Warm-season grasses flourish in regions with higher temperatures and they generally turn brown or go dormant in winter. It’s recommended that you feed this grass-type during active growth periods but not during the hottest months. Ideally, you want to apply the fertilizer in three phases: when the grass starts to green during early spring, again in late spring, and then one more time at the end of summer when the temperatures are not as extreme.
Q: How Soon Can I Mow My Lawn After Fertilizing?
A: Mowing your lawn at the right time is important when it comes to getting the best results from your fertilizer application. A good cut before you add fertilizer to your lawn will help to ensure that excessive growth and debris is removed, leaving behind healthy grass to work with. An application usually coincides with watering the grass well so that the nutrients can be absorbed quickly and easily. Wait a few days for the grass to dry and thicken before you mow again. If you are in the midst of a dormant season, you might have to wait up to a week or two before your lawn is ready for its next cut.
