Frequently Asked Questions

 Our advanced fertilization program utilizes high-quality granular and liquid slow-release fertilizers, ensuring optimal nutrient absorption upon watering. Our formulations consistently incorporate a balanced blend of three essential macronutrients: nitrogen, phosphorus, and potassium.
Nitrogen promotes chlorophyll synthesis, enhancing the vibrancy and lushness of your turf.
Phosphorus supports the development of a deep and robust root system, fostering long-term grass health.
Potassium strengthens the lawn’s resilience, aiding in drought resistance, disease prevention, and stress tolerance.

The nutrient composition of our fertilizers is adjusted seasonally to optimize their effectiveness. By fine-tuning nutrient levels throughout the year, we ensure your lawn receives the necessary elements to withstand environmental challenges specific to Virginia.

We use slow-release granular and liquid fertilizers with nitrogen, phosphorus, and potassium for optimal lawn health.

Pre-emergent herbicide typically comes in two different forms: liquid pre-emergent and granule pre-emergent. While each type is structured to combat sprouting weeds, they each have unique characteristics and application methods.

– Liquid pre-emergents are usually sprayed with tank sprayers or hose connections. One benefit of this pre-emergent is its widespread application, as its fast flow rate causes it to evenly coat your lawn. 

– Granular pre-emergents require little to no mixing compared to their liquid counterpart, which makes preparation a little easier.

Timing when you apply the pre-emergent herbicide is very important. Crabgrass seeds germinate when soil temperatures at the surface are consistently at 55F for 4 to 5 days. Pre-emergent herbicide works by interfering with the seed’s ability to germinate. Therefore, pre-emergent herbicide must be applied before the soil temperatures are right for crabgrass germination. Early spring is the time when we start the complete application.

– Goosegrass

– Barnyard grass

– Sandbur

– Foxtail

– Clover

– Knotweed

– Prostrate spurge

– Black medic

– Carpetweed

– Common purslane

– Pineapple weed

– Prostrate knotweed

– Spotted spurge

– Yellow woodsorrel

Once pre-emergent is applied, water your lawn carefully to activate the herbicide and encourage its penetration into the soil. Aim for 1 inch of water per week, either through rainfall or irrigation, to maintain optimal moisture levels without over-saturating the soil.

Spring is a great time for broadleaf weed control as temperatures warm consistently into the 60s and 70s, and the plants really begin to grow. Because of that, we are going to cover everything your lawn needs. Our weed control services are designed to target and eliminate any kind of weeds while leaving your lawn looking lush and healthy with the pre-emergent, which will help control the crabgrass growing in summer.

In Virginia, we typically deal with a variety of weeds, including broadleaf weeds, grassy weeds, and sedges. Here are some of the most common ones:
Broadleaf Weeds: These include bittercress, dandelions, clover, chickweed, plantain, and spurge. They have wide leaves and can spread quickly if not controlled.
Grassy Weeds: These resemble turfgrass and can be harder to spot. Common ones are crabgrass, goosegrass, japanese stiltgrass, and foxtail. They compete with your lawn for nutrients and space.
Sedges: Nutsedge, also known as nutgrass, is a persistent and fast-spreading weed that thrives in moist soil. It has a distinct triangular stem and can be tough to eliminate.
Effective treatment involves pre-emergent herbicides to prevent germination, post-emergent treatments for active weeds, and proper lawn maintenance to promote thick, healthy grass that naturally crowds out weeds.
Typically, our weed control treatments are applied at intervals of 6 to 8 weeks. However, to maximize effectiveness, we occasionally shorten this timeframe. For particularly persistent grassy weeds, treatments may be scheduled as frequently as every 20 days to ensure thorough eradication.
