Buyer’s Guide: All You Need To Know About The Best Fertilizer For My Lawn

When to Fertilize Your Lawn?

When to Fertilize Your Lawn

When to Apply Spring Lawn Fertilizer?

It’s all down to the type of grass you planted on your green. Most types are warm-season grasses that can easily take a fertilizer on a hot summer day; they will need it then because that’s how they are programmed to function. On the other hand, if the grass is a cold-season type, it is recommended to avoid fertilizing during summer, especially when the temperature is very high, as it can damage a plant. No matter if we’re talking about burning or killing grass slowly, the damage summer fertilizing can produce on cold season grass is considerable.

To understand precisely how lawn fertilizers work, you need to think of grass as a living organism, similar to a human body. Like you need different vitamins and nutrients from food and water, your lawn also needs minerals, vitamins, and nutrients to be healthy, and make the photosynthesis process more efficient. Sometimes, the soil isn’t able to provide all the required nutrients for the sod to grow properly, and you need to give it a boost. Like you’d take some vitamins when you’re feeling low on energy. Besides providing the best conditions for grass to grow and develop, a good lawn fertilizer will also make it easier for roots to develop and keep pests away. Even more than that, choosing the best time to fertilize lawn along with a high-quality product will keep your grass-plot in top shape all year long, even during harsh winters. Most fertilizers offer a balanced mix of Nitrogen, Potassium, and phosphorus, while some may also contain manganese, cobalt, iron, chlorine or zinc. While the absence of so-called, secondary nutrients isn’t necessarily bad for your lawn, making sure soils have them will improve the overall aspect and health.

As a general rule, you can use it on plants, in your garden. Especially true for products we reviewed, fertilizers do not contain any substances that could present a risk when used for plants like vegetables. Despite the controversy around bio food and the effects of herbicides and pesticides on vegetables, be sure that you can use any NPK lawn fertilizer for your garden too. However, if you’re using any product outside the ones presented in our comparison plan, make sure to check for any other chemical elements, like iron or Sulfur. They could represent a threat when used in high concentrations.

Well, there’s a short and a long answer to this question. If you’re living in a country with 4 seasons, the best time to start fertilizing your grass is in the spring. However, this doesn’t mean that you do it once in early spring and then you forget about it. Going back to the analogy we made with a human body, your lawn needs a constant feed of nutrients to grow healthy and solid. So, the best way to approach fertilizing schedule is by doing it once in early spring when grasses start to go green. Then, in late spring you should apply another layer to give it a boost before the summer when temperatures grow, and there’s a lot of chances for it to dry.

To verify your lawn makes it through the summer and stays in mint shape through most of the fall as well, make sure to use the fertilizer once again. Thus you should be good until next spring. This general template of lawn fertilizing can be applied for most types of yards. However, some particular types require different treatment.

Usually, if you didn’t finish a bag of fertilizers in one season, you should be able to store it for next year easily. Most fertilizers have a prolonged expiration date and, as long as you save them properly, you will be able to get the most out of them after a season as well. Proper conditions mean a bag should be well-sealed and kept in a dry and not too warm place. If you have moisture in a storage room, there’s a big chance that even the best lawn fertilizer will get lumps; however, even so, it is still usable. Just make sure to break any pieces before putting it in a spreader.
