Planting Trees and Shrubs: Choosing, Siting, and Getting Them Off to a Strong Start

Trees and shrubs are among the best investments a gardener can make, providing shade, privacy, wildlife habitat, and lasting beauty. This guide covers why trees and shrubs matter, how to choose a healthy specimen, where and how to plant them using current best practices, and how to care for them through their critical first years.
Tree planting, staking, and siting near utilities

Establishing new trees well means staking correctly for strength, choosing species suited to the site and infrastructure nearby, and understanding where certain popular choices create problems down the road.
Choosing and siting trees: root spread, utilities, difficult ground, and what to plant where

How far tree roots actually travel, what is safe near sprinkler lines and septic fields, which shrubs will grow under pines, what to buy for shade in a desert or a small Pennsylvania yard, and whether container, balled, or bare root stock establishes fastest.

Calcium Fertilizer Helps Trees Survive Winter

With winter around the corner, many gardeners will be preparing their landscape plants for the coming cold temperatures. With an estimated 1 million urban trees worldwide dying each year from freezing temperatures, researchers are trying to find ways we can better protect plants. A study in England suggests that fertilizing in fall with calcium nitrate can help trees survive both freezing temperatures and salt damage from products used to de-ice roads and walkways.
