Organic Weed Killer – Longmont, CO

Once spring rolls around the residents of Longmont, CO waste not time getting outside and enjoying the beautiful Colorado weather. Spring is also the time of year when most people start to think about on their lawns. Around late April is when the dreaded dandelions start appearing, but don’t worry, Organo-Lawn has you covered! Our One Earth weed control and fertilizer is by far the best organic weed killer around.

You shouldn’t wait until the dandelions all appear because our pre-emergent weed control gets applied in March which is when the lawns are still brown.

What People are Saying

I’ve been using Organo-Lawn for several years and have always been happy with their services and products. Today, Guy T. started the process of rejuvenating the lawn at the new (but very old) house I bought in Old Town, Longmont with a Top Seeding package. He was super friendly and careful to ask questions to make sure he placed the seed in the right spots, and he spent a little extra time going over the watering plan with me so my lawn will look great. Thanks Guy!

FAQ – Colorado Lawn Care

What is the best way to break up the clay soils in Longmont, CO?

Humate is an incredible soil conditioner and can be applied any time of the year. We can apply it in early spring, late spring, mid-summer, and in the fall; all work great. We suggest an application of Humate if you have soil lacking organic matter, a lawn lacking color and density, or heavy clay soils.

Humate is also smart to be applied 6-8 weeks before a special event and it will help bring out the dark-green color of the lawn. It will make the color of the grass a dark-green without causing it grow too fast. Humate is a soil conditioner and it helps release beneficial nutrients from the soil that are unavailable to the grass. Humate helps release the nutrients that are tied up in the soil, like nitrogen, iron, potassium, etc. These nutrients are often abundant in our soils, but are tied up or otherwise not available for the plant to uptake. We do suggest using Humate in conjunction with our 100% organic fertilizers to achieve the best results from your lawn care program.
