When should I fertilize my lawn?

Cool-season grasses such as fescue, bluegrass, ryegrass, and bentgrass respond best to a balanced approach to fertilization throughout the growing season. Apply fertilizer twice each fall, in September and November, and once again in the spring once the first flush of shoot growth has passed.

How much mulch do I need?

In order to ensure the unrestricted flow of air to and from the soil, layer fine mulch at a depth of between two and three inches, or up to six inches for coarse mulches such as bark chips. To determine how much mulch you will need, first calculate the square footage of the area you wish to cover by multiplying the length of the bed by the width. Next, multiply the square footage by the mulch height to arrive at the total number of cubic feet.

When and how much should I be watering my new trees?

Watering requirements are highest during the first few years after planting, until the root system has become fully established. Ensure the root ball and the surrounding soil are kept evenly moist but not saturated, watering slowly and deeply every one to three days depending on the soil conditions, temperature, and rainfall. You can view our Watering Trees & Shrub Care Sheet on our Resources page for more information.

How can I permanently get rid of weeds?

Mulch provides a natural barrier to inhibit weed growth in areas where there is exposed soil, such as flower beds or vegetable gardens. The best way to rid your lawn of weeds is through proper lawn care, including deep watering, aeration, fertilization, and mowing at the proper height.

How often should I mow my lawn?

On average you should expect to mow your lawn once every seven to ten days, with a goal of maintaining a height of around three inches in length.

When is the best time to run my irrigation system?

The optimal time to water your lawn is in the early hours of the morning before the sun gets too hot or the wind picks up, both of which can increase the rate of evaporation.

What trees will grow best in my landscape?

For best results, choose trees that are suited to your unique environment, taking into account space limitations, soil conditions, drainage conditions, exposure to sun and wind, and the hardiness zone. Be sure to purchase your new trees from a reputable, local grower to ensure the livability and longevity of the trees in your climate.

Do I need a backflow device?

In an irrigation system, you need a backflow device according to the City of Lawrence. A backflow device is designed to keep unsafe water from entering the clean water supply, by allowing it to flow in only one direction. This device should be used on any system where the water source for irrigation is potable (drinkable).

How often do I need to have my backflow device tested?

In accordance with the City of Lawrence, backflow device should be tested on an annual basis. This can be completed as part of routine landscape and irrigation maintenance to ensure seals, springs, and other moving parts are functioning properly.

What is the difference between drip irrigation and sprinkler systems?

A drip irrigation system is ideal for small areas or individual plants and can deliver anywhere between one to ten gallons of water per hour with little to no waste. Plastic pipes are installed close to the soil or on top of mulch, and the water drips slowly for maximum efficiency and absorption.

A sprinkler system is best suited for large areas and the water pipes are installed below ground. A pump mechanism is used to deliver the water to the above-ground sprinkler heads and the system can be set on a timer for ease of use. In areas where the ground is uneven or sloped, runoff, pooling, or erosion may occur and watering volume and duration may need to be adjusted.

What time of year should I plant trees?

Late summer to early fall is the best time to plant trees, ensuring they have enough time to establish their roots without having to expend the energy needed to produce new leaves. Roots grow best in cool soil and by planting in the fall your new trees will have time to grow roots in the colder months and again in the spring before the leaves develop.
