What is the ideal time of year for planting most ornamental trees?

Planting most ornamental trees is ideally done in early spring or fall, when temperatures are moderate. During these times, the weather is typically more conducive to root establishment, allowing trees to acclimate to their new environment before the more extreme conditions of summer heat or winter cold set in.

In early spring, the soil is warming up, and trees can begin to establish their roots as they start to leaf out, taking advantage of the nutrient-rich conditions found in moist spring soil. In the fall, trees can take advantage of the cooler temperatures and often wetter conditions, allowing them to develop a strong root system before winter dormancy. This timing helps trees to be more resilient and flourish once the growing season resumes.

Planting during winter, when the ground is frozen, presents challenges for root establishment and can lead to stress for the trees. Late summer, during peak heat, can cause additional stress on newly planted trees due to higher temperatures and possible drought conditions, making it harder for them to establish roots. Lastly, while it may technically be possible to plant at any time during the year, this does not align with the best practices that promote healthier growth and successful establishment.
