Best Time to Plant a Tree: Spring and Fall
Are you thinking of planting a tree? Fall is the best time to do that. It gives the tree plenty of time to root itself. A tree starts growing the second it’s planted. It will continue to grow as long as the soil temperature stays above 40°F (4°C). By the time spring comes, the tree will be established and growing.
Another reason to plant in the Fall is the soil. It’s a better fit for digging plant holes than in the Spring. Plus, the summer’s warmth still lingers in the soil. That keeps the soil moist enough for digging, making it perfect for planting.
Some people worry that winter will kill a tree planted in the Fall. No so. Trees go dormant in the winter so they can withstand the cold. In other words, they “hibernate,” like animals do in the winter. So, if you plant a sapling early enough in the Fall, it will have plenty of time to establish itself before the winter.
The tree will also have two growing seasons before the summer heat arrives and a healthy enough perception to survive. Ideally, you want to plant a tree at least six weeks before freezing temperatures arrive. Use October as a deadline for planting a tree.
Spring is also a Good Time to Plant
Spring is also a good time to plant a tree. But doing so then is risky. It might be too rainy for the soil to become stable enough for the tree to grow. That could prevent the tree from establishing itself enough before the summer heat arrives. Intense summer heat can kill a tree.
Spring, however, has one significant advantage over the Fall when planting a tree. Many local nurseries stock up on inventory in the Spring. So, you have more trees to choose from in the Spring than in the Fall. You may also have a better-quality tree to choose from in the Spring.
The time of the year you plant your tree, however, will only matter if you plant it in the right spot. Location is as critical as the time you plant it. Make sure you don’t plant the tree too close to existing structures. You’ll also want to research how much sun, wind, and water the tree prefers.
Knowing that information means you’re better able to pick a spot compatible with those conditions. And remember to call the free 811 Service to ensure there aren’t any underground utilities where you plant the tree. The tree’s roots could become a real problem for the utilities in time.
Finally, give your tree plenty of water—roughly one gallon of water per inch of diameter on the trunk. Mulch will help keep the tree moist and happy. Use up to 4″ and keep space between the trunk and the mulch.
Crabapples: A Good Choice to Plant
Plenty of beautiful flowering trees are available when planting a tree. The Crabapple (Botanical name: Malus spp.) is an excellent choice if you are looking for a compact tree that brings year-round interest. Gorgeous spring buds, handsome summer foliage, and excellent fall color are among the Crabapple’s main draws. The Crabapple’s growth rate is moderate. It grows to about 15-20’, with a spread of about 15-20’.
The Crabapple blooms in mid-to-late Spring and features fragrant white, pink, magenta, or red blooms that typically last 1-2 weeks. Crabapple fruit ripens from late summer to mid-fall. Most cultivars have red fruit, but you can find yellow, maroon, and orange. Crabapples come in all shapes and sizes, including spreading, weeping, dwarf, vase-shaped, and columnar.
The tree’s flowers bloom at slightly different times depending on the cultivar. One design consideration with Crabapples is whether to plant multiple types of Crabapples that bloom for a more extended period or plant the same type that provides an explosion of fragrance and color simultaneously.
A Crabapples’ fruit, however, is more than just ornamental. It also provides much-needed wildlife value, but its fruit is too sour to enjoy. The fruit comes in various sizes and colors depending on the cultivar. Some cultivars, such as the Malus ‘Guinevere,’ shown below, provide winter interest with the fruit.
