Question
Every year I fertilize my lawn according to the information on the packaging, and yet, during the summer fertilization, despite all my efforts to spread the fertilizer properly, the lawn burns. What can I do about it?
Answer
It makes no sense to apply a synthetic (chemical) fertilizer to your lawn in the middle of summer, no matter what it says on the label. If the soil is even the slightest bit dry, which is often the case in July, grasses are bound to burn, because fertilizers are highly concentrated and are harmful to plants unless diluted properly. I suggest you forget what the fertilizer label says about the frequency of lawn fertilizer applications (most recommend 3 or even 4 applications a year!).
A spring application is more than enough to maintain a beautiful lawn. I especially recommend slow-dissolving organic fertilizers for use on lawns, because even in spring, it’s easy to burn the lawn with synthetic fertilizers. Organic fertilizers are less concentrated and therefore less likely to cause damage.
Remember, fertilizer manufacturers aren’t in the business of making beautiful lawns, they’re in the business of selling as much product as possible. You have to turn a deaf ear when they urge you to overuse their product. I suggest never applying more than a quarter of the recommended dose of any fertilizer.
Topdressing
Topdressing with compost is often more beneficial than using chemical fertilizers for your lawn. By enriching the soil with balanced nutrients and improving its structure, compost helps retain water and promote root growth. Unlike chemical fertilizers, compost won’t burn your lawn, even in summer. What’s more, it encourages beneficial microbial activity and is more respectful of the environment. By applying a thin layer of compost once a year (even that is a lot!), you can maintain a healthy lawn without too much effort. It’s simple, effective and environmentally friendly!
