OSKALOOSA — The Mahaska County Master Gardeners are hosting a presentation by Emma Hanigan which will cover the three critical phases of tree establishment: selection, planting and care. Attendees walk away with measurable, practical skills for success with young trees.
The event is open to the public and for anyone wishing to learn about the topic: both adults and youth and there is no cost to attend due to support of ISU Extension and Outreach- Mahaska County and Mahaska County Master Gardeners. The presentation will be on Tuesday November 18 at 7 pm and at the Mahaska County Extension office auditorium, 212 North I Street Oskaloosa. Please enter through the south door.

Attendees will learn to analyze a site to determine the optimal planting location and species, focusing on biodiversity and techniques to maximize tree benefits. They will also learn to differentiate between nursery stock types and how to select the healthiest tree at the nursery. The session will provide a step-by-step guide on proper installation. Participants will learn how to correctly size and dig the planting hole, properly position the tree to ensure the root flare is exposed, and execute essential planting procedures like root pruning. They will learn best practices for mulching and tree staking or caging to promote long term success. Focusing on the establishment phase, the final segment will cover new tree watering, maintain effective mulch rings and how to perform basic structural pruning to guide the tree’s development.
