Urbanization is good for pests and bad for trees

July 23rd, 2014 by

My wife is from a neighborhood outside Baltimore called Lawyer’s Hill. This is where, in the 18th century, lawyers (and I assume doctors and other gentlemen) had country houses and could escape the summer heat. It is only 3 miles … Continue reading

GrowIt! Launch Event — Help create the newest plant app!

July 16th, 2014 by

GrowIt! Launch Event

Help create the newest plant app!

Thursday, July 17        6:00 – 7:30 pm

The State Botanical Garden of Georgia

GrowIt! is, a mobile app that is also social. It helps you find plants and ideas that work well in your area by connecting you to photos and comments of gardeners in the same area. It will be available in the App Store in July, but before it can be marketed on a large scale, folks around the country need to be entering data.

GrowIt! is an initiative of Ball Horticultural Company, but includes all plants, not just one brand. The goal is to engage the next generation of gardeners (Millennials mostly, ages 20-38).  This free mobile app is the first of its kind creating a social platform for users to promote plants they love and help others steer clear of plants that just don’t perform.  The app uses geo-locating technology in the phone to ensure that the users only see local information.  This will help ensure the next generation gardener knows what they should and should not buy so that their first gardening experience is a success.

To make this a successful tool for the next generation content needs to be built within the app.  An important aspect of GrowIt! is that it runs entirely on user submission with none of the digitally enhanced images that can come from big brands.  So….we need REAL images from REAL gardeners supporting a real social network.  So GrowIt! Is hosting a gathering at the State Botanical Garden of Georgia Visitor Center (2450 South Milledge Avenue, Athens), where garden enthusiasts from the community download the app, walk around the gardens, take photos, and rate plants.

Your comments and photos will help guide new gardeners on the best plants and the ones to avoid. Check it out at www.facebook.com/growitapp or www.twitter.com/growitmobile.

Two recent publications will help growers, landscapers, retail outlets, and the public understand the risks and benefits of neonicotinoid insecticides without the hype. These extension publications provide a balanced account of the current research and restrictions. Planting garden center flowers is good for bees and other beneficial insects was published by Dr. Dave Smitley at Michigan State University.  

The second Neonicotinoid Pesticides and Honey Bees by Timothy Lawrence and Walter Sheppard at Washington State University provides an accessible literature review of research related to honey bee exposure to neonicotinoids.

branches of maple trees and migrate to the underside of leaves in the spring. Once there, they use their mouthparts to pierce leaf cells and feed on cell sap. This causes fine flecking called stippling and eventually leaves turn gray or brown after heavy feeding. Maple spider mites have multiple generations per year which enables them to become quite abundant during a single season. These pests are a more serious problem in nurseries due to the close proximity of potted trees and applications of broad spectrum insecticides like permethrin. For example, our research has shown….continue reading….
