The best time for planting trees is typically in the fall or early spring. This is when the soil is cool and moist, allowing the tree's roots to establish themselves before the hot, dry summer weather arrives. In the fall, the tree can focus its energy on root growth rather than leaf and branch development, giving it a head start for the next growing season.
Planting in the spring is also a good option, as the tree can take advantage of the cool, wet conditions to get established before the summer heat. However, be mindful of any late spring frosts that could damage new growth. Regardless of the season, it's essential to water the tree regularly during its first year to ensure its survival and healthy development.
