Got Nature? Blog

The Purdue Landscape Report, a blog which provides science-based, timely information regarding Midwest landscapes to commercial growers, garden centers, landscapers, arborists and the general public, was recognized with the Extension Division Education Materials Award for Outstanding Blog at the American Society of Horticultural Science convention in August.

The Purdue Landscape Report is a collaborative effort between Purdue Extension specialists and diagnosticians in the areas of horticulture, entomology, plant pathology, urban forestry and turf science. Articles cover everything from tree maintenance to pest and disease problems and management to plant selection.

“Our Purdue Green Industry Team brings together many disciplines and expertise for the industry and homeowners as well as any other university in the country,” Nursey and Landscape Outreach Specialist Kyle Daniel said. “The research and outreach efforts of each member of the team contributes to helping the industry be more sustainable, efficient, environmentally conscious, and profitable. The Purdue Landscape Report is one way that we present science-based information to our stakeholders around the state. In addition to this information being distributed locally, there are many subscribers from across the country.”

The PLR team includes:

• Kyle Daniel – Nursey and Landscape Outreach Specialist, Purdue Horticulture and Landscape Architecture
• Rosie Lerner – Extension Consumer Horticulturist, Purdue Horticulture and Landscape Architecture
• Cliff Sadof – Professor, Entomology Extension Specialist
• Tom Creswell – Clinical Engagement Professor, Director of the Plant & Pest Diagnostic Laboratory; Purdue Botany and Plant Pathology
• Janna Beckerman – Professor of Botany and Plant Pathology
• John Bonkowski – Clerk, Purdue Botany and Plant Pathology
• Lindsey Purcell – Purdue Extension urban forester, Purdue Forestry and Natural Resources
• Gail Ruhl – Visiting Scholar, Purdue Biological Sciences
• Elizabeth Barnes – Exotic Forest Pest Educator, Purdue Entomology
• Todd Abrahamson – Purdue Plant & Pest Diagnostic Lab Secretary
• Lori Jolly-Brown – Extension Events and Communications Coordinator, Purdue Horticulture and Landscape Architecture
• Kirby Kalbaugh – Application and Systems Administrator, Purdue Horticulture and Landscape Architecture

Since launching in February 2018, the Purdue Landscape Report has included more than 144 articles. The website boasted more than 75,000 unique article downloads in 2019. PLR is also sent out in a bi-weekly email newsletter to more than 4,000 subscribers nationwide. The blog has brought in 137,000 unique visitors thus far in 2020.

In August, the Purdue Landscape Report staff also began a live, virtual series every other Wednesday, which addresses articles and hot topics. In just two months, that series has had more than 1,100 views.

The Purdue Landscape Report

The Nature of Teaching, a Purdue Extension signature program, was honored as the third place finisher in the central region for the Environmental Education Award presented by the National Extension Association of Family and Consumer Science (NEAFCS).

Question: Can tree roots cause damage to a home’s foundation? I have a 3’ in diameter pin oak tree that is within 10 feet of my house. A certified arborist took a look at it and said that he would like to use an Air Knife to expose the roots near the foundation (a walkout basement) to determine if the roots are causing damage and/or need to be pruned, or whether the tree needs to be removed since it is situated too close to the house. Before I spend $500 for them to use the Air Knife, I wondered if you thought it would be worthwhile or not necessary.

Answer: Tree roots can damage a house foundation, with an invitation to do so. Tree roots are very opportunistic and will only grow and penetrate where it is easiest to grow such as friable soils and mulch. Typically, when roots encounter solid, impervious surfaces such as pipes, sidewalks, curbs and foundations, they are redirected laterally or up and over. However, if there is a breach or a crack nearby, they can and will exploit those voids in search of moisture. Such as sewer pipes aren’t damaged by the roots, they are just very capable of finding those leaks and moving into the moist and often nutrient-rich pipe.

Roots normally grow horizontally and not very far beneath the soil surface. Sometimes when roots encounter the looser backfill soil near the foundation, they can abruptly start growing down. You may be able to locate these roots, if they exist, by excavating a foot or two down within a few feet of the foundation. If you find a suspect root, cut it off. Unfortunately, in some cases excavation down to the base of the foundation may be necessary. This may have to be done anyway to repair and stabilize it. Cutting the roots should prevent future problems, especially if a root barrier is installed to prevent re-growth.

In this edition of ID That Tree, Purdue Extension forester Lenny Farlee teaches you about the state tree of Indiana, the tulip tree. It is also known as the tulip poplar or yellow poplar, although it is more closely related to the magnolia. This tree is known for its simple tulip shaped leaves and colorful flowers in the spring, although they are often high up on the tree.
