What better day, than Earth Day, to publish our final installment on our three part series on the secrets to a healthy lawn? As we’ve said, a North Texas lawn needs three things to thrive: sun, water, and food. If you want to read our first two installments follow these links.
Today I want to talk about food for your lawn. Typically in North Texas we start fertilizing our lawns as the weather warms up in late February or early March. The exception is when we’re having a particularly cold winter (like this year!) When we have a cold winter we’ll postpone our treatment for a few weeks. When we fertilize is the same for all lawns, but the what is dependent on your individual lawn…your type of grass.
Bermuda grass likes a kick start to help it green up quickly so we apply a high-nitrogen fertilizer. If you’re a DYI person, be sure and find a ratio of 28-3-10 (all fertilizer bags will have three numbers separated by a dash (-) usually located across the top. The three fertilizer numbers represent the percentage of Nitrogen (N)- Phosphorus (P)- Potassium (K), in that order. These numbers will always be listed on the bag in bold writing.)
St. Augustine and zoysia are different than bermuda. During our warm, wet spring weather they are prone to a fungus called brown patch. Just like the name suggests, this causes patches of brown to creep into the grass. These brown patches feed off of nitrogen which is why we use a different ration, 5-10-31 (The last number (31) promotes better root growth, a good thing right after winter since both St. Augustine and zoysia are cold sensitive.) Once we’re past brown patch season we’ll switch over to the higher nitrogen fertilizer (usually in late May.)
So what does all of this mean for us today? We’re coming off the the 6th coldest winter on record in North Texas with 40 days below 20 degrees. Many are looking at their brown lawn and wondering if they will ever have a nice looking lawn again (I’ve even had a few customers mention they are considering replacing their lawns because they look so bad.) My advice. Patience. If you have the three keys to a healthy lawn (sun, water, and food,) your lawn will recover.
