The grass doesn’t have to be greener on the other side…There are ways to keep the grass green on your side of paradise. With all of the moisture the month of February has brought to the Front Range and our Mountains, once warmer temperatures start to arrive, our landscapes will green up quickly!
As we move closer to spring our ambient daytime temperatures and soil temperatures creep up, triggering the first signs of spring. Our lawns start to green up, early spring blooming bulbs-like crocus awaken, and buds on trees start to swell. All sure signs that spring is on the way.
The months of March and April are the perfect months to apply your pre-emergent fertilization to your lawn areas.
Here are some things to keep in mind about pre-emergent applications:
*A pre-emergent works to prevent weeds from making it to the surface of the lawn, not prevention of germination.
*Pre-emergent applications are for annual weeds, not perennial weeds such as dandelions.
*Most pre-emergents commercially available today have a special coating, allowing them to sit on the lawn areas for 2-3 weeks without the effects of potential burning if not watered in.
*Pre-emergent lawn fertilization products typically last 120 days.
At your Denver Tree Specialists own lawn fertilization products are balanced. Meaning that ours are balanced with Nitrogen, Phosphorus, and potassium customized for our regional needs. We offer three programs: Organic, Synthetic, or Season long fertilizations.
Our fertilization program runs from roughly March to October. With our Organic and Synthetic programs, we offer up to four applications of fertilizer and broadleaf weed control up. If you authorize a full program, you will receive free weed re-sprays. During the hottest month of our season, July, we opt to treat the lawns with Black Gypsum. For more information on this product, please visit the lawn care section of our website.
There are several things that a homeowner can manage for themselves to keep their lawn healthy and lush, while keep majority of weeds at bay.
*Mow to maintain the height of your grass between two and three inches. Scalping a lawn leads to drought stress and low heat tolerance. Allowing a turf grass to grow too tall, leads to more insect, weed, and disease issues.
*Mowing operations should be scheduled to not remove more than one-third of the height in one mowing
*During the flush of spring growth, you may need to mow more than once a week
*During the hottest months-July and August-allow the turf to grow one inch taller than normal and increase the times between mowing.
*Leave your grass clippings…These provide much needed benefits to the lawn (organic matter and nutrients)
Along the Front Range, we recommend having your lawn core aerated at least once per year. We also recommend that you routinely check your sprinkler heads and adjust your watering times as needed based upon our temperatures and weather events. Many new irrigation clocks allow for a rain sensor to be added. When we receive moisture, this sensor turns off the irrigation system. Proper watering is a key part to the overall health of your lawn.
With proper fertilization, watering, and mowing you will have a lush green lawn that is capable of choking out most pesky weeds.
One last tip: if you want to Over-seed your lawn this spring, the best months are March and April. But, remember… if you over-seed you cannot apply a pre-emergent application before or after the over-seeding, your seed will not germinate.
As always, if you ever need assistance with your lawn, please call one of our Arborists…we are more than happy to help out.
