save your lawn with core aeration services

Harold Enger, Spring-Green’s Director of Education, received a question from a homeowner about fixing his dead lawn. After hearing about the problem, he recommended core aeration and overseeding to help revive the lawn. “My lawn is brown with few things growing (even weeds).

I thought about tilling my entire lawn but its costly ($2k). I have aerated in the past […]

I recently attended a class on identifying grasses and weedy grasses, sponsored by the Illinois Turfgrass Foundation. The class was led by Dr. Tom Voigt, Professor of Horticulture from the University of Illinois.

Earlier this summer, I spoke about slime molds growing in the mulch of landscape beds. The one that most people see is called Dog Vomit slime mold since the name describes the appearance of the slime mold—slimy, yellowish and gelatinous. Another type of fungal growth is showing up in a number of mulch beds right now – stinkhorns. Stinkhorns are common in the US and usually show up in the late summer and early fall. They can form in lawns or in mulch beds. Stinkhorns get their name from the […]

close up of Maple Tar Spot

I recently was conducting some training classes with the Field Service Professionals in Mequon, WI and I saw a tree disease that seems to be increasing in frequency over the last couple of years – Maple Tar Spot.

Besides showing on several species of Maples, Tar Spot can also develop on Boxelder trees and even Willows. Tar Spot is […]

Your shoes also seem to have taken on an orange-ish sheen. This is all happening due to a common turf disease that has been aggravated […]

First comes rain, then comes the mushrooms! Not only does an abundance of rain mean that your grass is going to be growing at an unstoppable pace, it means that you’ll probably start seeing some mushrooms peaking up through the green. Mushrooms are fungi and in many cases they are beneficial since they are the fruiting bodies the organisms that break down organic matter, like thatch, old roots, branches and other remnants of buried wood that may exist underground in your lawn.
