Lawns, Gardens & Landscapes

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.

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.

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.

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 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.

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.

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.

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.

There are so many decisions to be made when it comes to vegetable gardening. Selecting the right location, determining what to plant, even how many plants you might need. One topic that might not have crossed your mind is how to make the vegetable garden more water conscious. Conserving water in the vegetable garden may sound more difficult than it really is.

Warm summer temperatures prompt vegetable crops to grow and thrive. Keeping garden vegetable crops hydrated is crucial for these plants thriving as water is essential to the photosynthesis process, plant growth, and production. When water availability is reduced, carbohydrate production in the plant, the building block of plant nutrition, decreases significantly. That decrease leads to reduced growth, vigor, and crop production potential. Here are some very simple tips to help provide the needed moisture levels in vegetable and fruit crops.

Tall fescue tolerates dry periods better than KBG due to a deeper root system that uses moisture deeper in the soil. However, it does not have the physiological ability to go dormant to avoid dying from drought. If tall fescue begins to turn off color from a lack of water, it requires irrigation.

Many urban landscapes have a forlorn narrow planting strip between the curb and sidewalk, otherwise known as a “hell strip”. Healthy curbside plantings help filter and absorb rainwater, preventing landscape fertilizers and other pollutants from entering storm drains.
