Why plant a tree? There are plenty of benefits to growing trees. First of all, trees are easy to care for. Once they’re established, most trees don’t require much additional maintenance. They provide shade, privacy, and shelter from the elements. All plants provide critical environmental services, such as making oxygen and helping clean the air and water. Trees also provide a critical food source for humans and wildlife.
If you’ve decided to add a tree to your landscape, get ready to do some digging. September is one of the best times of year for planting trees. Whether deciduous or evergreen, most species naturally go dormant during the winter, and they start slowing down during the fall. At this time, you can easily transition them from a pot to a permanent location. When they wake up again in the spring, they will be ready to direct all their energy into setting in and establishing their new home.
Timing is important with fall plantings. You want to get your saplings in the ground while the soil is still workable; not too soon, but also not too late. Ideally, time your fall transplants so they get at least six weeks of growth before the first average fall frost. It’s okay if they get less than that, but they will have a growth advantage if they have a chance to take hold before going completely dormant for the winter.
Now let’s dig right in and look at the details of 15 types of trees you can successfully plant in September before the first fall frost.
American Fringe Tree
botanical name Chionanthus virginicus | |
sun requirements Full sun to partial shade | |
height 12 – 30 feet | |
hardiness zones 3 – 9 |
The American fringe tree is a little-used landscaping tree that has great potential. This small tree is native to the eastern United States, where it grows in the understory of moist hardwood forests. In the home landscape, the fringe tree does well with full sun or light shade and rich, moist, well-drained soil.
In the spring, American fringe tree puts on a spectacular show. The feathery, fringelike flowers cover the tree with a showy white blanket of elongated petals. At a distance, a fully flowering tree appears almost entirely white. For the rest of the year, these modest trees are an appealing rounded green form in your landscape, quietly complimenting your other greenery. The leaves turn golden yellow in autumn.
American Redbud
botanical name Cercis canadensis | |
sun requirements Full sun to partial shade | |
height 20 – 30 feet | |
hardiness zones 4 – 9 |
The American redbud is a small understory tree native to central and eastern North America. It is a common tree along forest edges, roadsides, and urban habitats. This easy-to-grow tree would do well in a partially shaded location with taller trees in the vicinity. The soil should be organically rich, generally moist, and well-drained.
American redbuds are best known for their showy pale pinkish-purple flowers. These pea-like flowers appear in very early spring before the leaves emerge. They line the branches in small clusters for a very colorful welcome to warmer weather. Shortly after flowering, heart-shaped leaves grace the American redbud. You’ll find several cultivars of this tree, some with purple foliage.
Flowering Cherry
botanical name Prunus spp. | |
sun requirements Full sun | |
height 15 – 60 feet | |
hardiness zones 4 – 9 |
Flowering cherry trees are highly ornamental small to medium-sized trees with nicely rounded crowns. You’ll find a wide variety of flowering cherry cultivars to liven up your landscape. The spring-blooming blossoms may be pure white or varying shades of pink. Regardless of color, pollinators love the abundant flowers that cover the trees in early spring.
Your flowering cherry tree will appreciate a sunny location where it can shine without nearby vegetative competition. The soil should be rich, moist, and well-drained. Check the preferred climate zone for the species you want because some of these trees are more cold-hardy and heat-tolerant than others. Whichever you choose, plant it in the fall, and your tree will be ready to flower the following spring.
Edible Fig
botanical name Ficus carica | |
sun requirements Full sun to partial shade | |
height 10 – 30 feet | |
hardiness zones 7 – 10 |
Have you ever wanted to grow your own fruit trees? If you live in a warm enough climate zone, you’ll find fig trees are remarkably easy to grow. These compact fruit trees have a pleasing rounded form. They grow best in full sun with rich, moist, well-drained soil.
The edible fig fruits ripen in mid-summer. They are soft, sweet, and delicious. Enjoy your figs fresh, frozen, dried, cooked, or preserved. The leaves of the fig tree are large and palmate with a slightly rough texture. Most commercially available fig cultivars produce plenty of fruits without the need for cross-pollination with another fig tree.
Fir
botanical name Abies spp. | |
sun requirements Full sun | |
height 30 – 260 feet | |
hardiness zones 4 – 7 |
Do you live in a cooler climate and want a beautiful evergreen tree? Try one of the native fir species. These attractive, long-lived trees are very cold hardy and love climates with long winters and cool summers. Firs thrive in full sun or light shade with well-drained soil.
These needled evergreens are commonly used as Christmas trees and harvested when they’re still quite young. A mature fir can reach over 100 feet tall in natural conditions, although they rarely grow over 70 feet tall in cultivation. If you prefer a compact variety, look for dwarf cultivars. The short, silvery-green needles of a fir tree add interest and appeal all year as well as provide an excellent privacy screen and wildlife habitat.
Flowering Crabapple
botanical name Malus spp. | |
sun requirements Full sun | |
height 10 – 44 feet | |
hardiness zones 3 – 9 |
Are you looking for a smaller ornamental tree with fantastic spring flowers? Flowering crabapples delight each spring with their prolific blooms that cover these compact trees with colors ranging from white to pale pink to deep burgundy rose. The flowers are spectacular and will be buzzing and fluttering with pollinator activity.
Although crabapple fruits are edible, most people don’t eat them because they are very tart. You can best use them for jams and jellies or leave them on the tree for ornamental value and to feed the birds. For smaller areas, choose a dwarf variety of flowering crabapple to fit in any part of your landscape.
Flowering Dogwood
botanical name Cornus florida | |
sun requirements Full sun to partial shade | |
height 15 – 25 feet | |
hardiness zones 5 – 9 |

Pollinators enjoy the flowers, and birds feast on the bright red berry-like fruits that appear in late summer and fall.
Flowering dogwood performs best in a partially shaded location. In hotter climates, select a site that receives some afternoon shade, or your dogwood leaves can scorch in harsh midday sun. The soil should be rich and moist with good drainage. In the fall, you’ll enjoy the bright red to purple autumn foliage display.
Hawthorn
botanical name Crataegus spp. | |
sun requirements Full sun | |
height 10 – 35 feet | |

The giant fragrant white flowers bloom in late spring and early summer and can reach over six inches across.
Southern magnolias command attention. You’ll want to give your magnolia tree plenty of space so it can reach its full potential. The dense canopy of leaves prevents other vegetation from growing under these trees but offers plenty of shelter for birds, insects, and other wildlife. You’ll enjoy these trees providing life and color to your landscape throughout the year.
Frequently Asked Questions
Can I also plant new trees in the spring?
Yes, spring is another excellent time to add new plants to your yard. For many species, fall is the best time because your plants are getting ready to go dormant during the winter. During this time, they will rest and wait. When spring comes, they will come to life and be ready to grow with fresh vigor.
What else can I plant in September?
September is a great time for planting. You can, of course, plant many species of trees in September. While you’re out working in your yard, you can also divide and thin your over-crowded perennials.
If you’d like to add perennials to your landscape, fall is the perfect time to transplant new wildflowers. And if you want to start some new wildflowers from seed, sow your seeds in prepared flower beds during September or October and they’ll germinate the following spring. When warm weather returns, your yard will be alive with fresh new growth!
How should I care for my newly planted tree?
Before you plant your tree, prepare your site well. Loosen the soil, remove weeds, and amend the soil as needed. Loosen the roots before you place your tree in the ground. It will have an easier time getting started than if you plant it with a dense tangle of pot-bound roots.
After planting your tree, add some mulch around it to help protect the tender new roots from harsh conditions. You’ll also want to water your tree well immediately after planting and keep it moist for the first couple of weeks after transplanting.
How do I choose the best tree for my yard?
Look at the USDA Plant Hardiness Zone map to learn your zone. You’ll need to choose a tree that will grow well in your zone. Next, take note of the conditions in your own yard. Do you have full sun, partial sun, or full shade? Is your soil wet, moist, or dry? Is your soil well-drained or does water pool and create soggy conditions?
Identify where you want to grow your tree and select a tree that’s well-suited to the sun levels and soil type at that site. Finally, consider why you want a tree. Do you want a large shade tree or a small ornamental tree? Are you looking for something with evergreen foliage, spring flowers, or fall color? See if you can find a few species that match all of your requirements and those will be the best trees for you.
