Lawns, Gardens & Landscapes

Eastern Nebraska tends to have high soil pH, also known as alkaline soil, which can cause problems for some plants, like river birch, pin oak, big-leaf hydrangeas and blueberries to name a few. Alkaline soil changes the availability of certain plant nutrients in the soil, often making them less available, resulting in deficiency symptoms.

When we plant a garden or flower bed, we think about sunlight preferences, color and bloom times most often, but there are other factors to think about including water requirements for the plants. All plants need water to survive, but they differ greatly in how much they need. Some plants are best planted along a pond edge or other very wet location because they like swampy, over irrigated locations. Where other plants require dry, well-drained soil. There are even some great plants used in rain gardens and similar areas that actually do well in both wet locations as well as dry conditions to overcome the changing environment when water collects during rain events and dries out between rains.

Tree health is often a reflection root health. Good practices to improve root health include properly applied organic mulch, good water management to avoid overwatering but providing water as needed during dry periods, and avoiding root damage from construction or changes in soil grade.

As I walk around my yard with my dog, I wonder about the impacts it has on my turf for the spring. Walking on frozen turf can have detrimental effects. During the spring and summer, we can walk on our lawns and turf fields with no damage. During the growing season, turf plants can recover from traffic through active regrowth. However, during the winter the turf is dormant and cannot recover from the damage until the spring.

When we think of stormwater runoff we often think of rain. Snow melt during winter can also become stormwater runoff and carry pollutants to surface water. During winter the ground is usually frozen and melting snow cannot infiltrate into soil as a light rainfall will do. Depending on the amount of snow, this can lead to increased runoff during winter.

As the growing season draws to an end and we put away our gardening equipment, it’s also important to store any remaining pesticide products properly to prevent contamination and maintain product effectiveness for next year. But even more important, being careless with pesticide storage is an open invitation to disaster, in the form of a pesticide poisoning or spill which could contamination ground or surface water.

Currently, most of the state is in at least a moderate drought, with many areas affected by severe, extreme, and even exceptional drought conditions. The Farmer’s almanac is calling for a cold, dry winter, again, so moving into that with drought conditions already could be devastating to our plants.

Phosphorous is an essential plant nutrient. Phosphorous can also lead to impaired water quality in surface water like lakes and ponds. Applying phosphorous responsibly is important to turfgrass growth and to water ecosystems.

All lawn sprinkler systems, whether they are in-ground or above ground, have flaws.  Some of the biggest are gaps and overlaps. Actually, a well designed irrigation system, or the use of above ground spray heads utilizes overlaps in the form of “head-to-head coverage”.  This involves water from one head spraying all the way to the adjacent head and vice versa.  Since twice as much water is applied near the head as is at the end of the water stream, an even amount is applied if the system has good head-to-head coverage.

Lawns need about one inch of water per week. During the hottest part of summer, they may need one and a half inches. Do you know how much water your irrigation system applies? Lawns require uniform watering so one area is not under watered while another is overwatered. Do you know if your system waters uniformly? Lawns are best watered deeply but infrequently. Do you know what this means and if you’re watering program meets this recommendation?

Currently most of southeast Nebraska is in the ‘Moderate Drought’ level on the drought monitor. As we move into the spring and summer we could see the drought continue and irrigation will be critical.

Many Nebraska soils have high clay and silt content making them prone to compaction. Foot traffic from both human and pets, equipment and vehicles are all common causes of soil compaction. Look for the following as signs of potential soil compaction in your landscape.

Minimizing pesticide usage in the home garden is a great way to protect yourself from chemical exposure, while also protecting the environment and surface water resources. But pest control - insects, diseases and weeds - are challenging for the home organic vegetable gardener.  Today we’ll focus on techniques for insect and disease control. Gardeners using organic techniques may have to adjust their expectations at the outset and begin to accept a higher level of insect and disease damage in the garden.

The past 22 months have brought a tremendous burden to the U.S. and other countries around the globe due to the COVID-19 pandemic.  One of the unforeseen issues is the spillover effects that the supply chain problems and worker shortages have had on the lawn and landscape industries.  While this post is not intended to encourage hoarding of products along the lines of buying up all the toilet paper in sight, it is helpful to be aware of potential price increases and product shortages at the garden center in 2022.

It’s definitely getting colder outside. Winter isn’t officially here yet, but it is on its way. This is the time of the year where we give up on plants, but there are some things to consider prior to winter to ensure their survival. Winter Care of Turf

In spring 2021, many gardeners and landscape managers in eastern Nebraska had severe plant damage to boxwood shrubs. In many cases, entire plants were dead. In others, all branches above the protecting snow line were brown, dried and dead. Although boxwood was not the only type of plant showing damage in spring 2021, why was the damage so widespread on this species?

We are getting closer to fall which is a great time to work on improving your lawn. Late September and early October are great for spraying lawn weeds. When dealing with pests in your lawn, be sure to use pesticides correctly for the best success and for the least amount of damage to the environment.

Plant roots grow in soil pore spaces. Pore spaces are also where oxygen is found. Just as plant roots cannot grow without water, they cannot grow without oxygen. Soil pore space is important to plant growth and efficient water use. Soils with good structure have adequate pore space making them well drained while still having good water and nutrient holding capacity. Ideal soils have 50 percent soil particles and 50 percent pore space. An important aspect of good soil structure is soil aggregation.
