Tree & Shrub Planting and Care in Indianapolis, IN

Quick answer

Healthy trees and shrubs around Indianapolis start with correct planting: root flare at or slightly above grade, a wide hole in heavy clay, roots loosened, mulch kept off the trunk, and steady watering through late-summer dry spells. Early fall and spring are good planting times, and a diverse species mix matters after emerald ash borer.

Trees and shrubs are the long-lived backbone of an Indianapolis yard, and many neighborhoods are still replanting after emerald ash borer killed untreated ash trees across central Indiana. Others are replacing worn-out foundation shrubs from the 1990s and 2000s, or pulling out invasive shrubs like bush honeysuckle. Getting the planting and pruning right saves money for decades.

Planting it right

Find the root flare. The spot where the trunk widens should sit at or slightly above the surrounding soil. Planting too deep is one of the most common causes of slow decline.
Dig wide, not deep. A hole two to three times as wide as the root ball lets roots spread. In heavy clay, avoid a smooth-sided "bathtub" that holds water around the roots; on very wet sites, planting slightly high helps.
Fix circling roots. Tease out or cut roots wrapped around the pot.
Mulch correctly. A few inches of mulch spread wide, kept off the trunk. No mulch volcanoes.
Water through establishment. New trees need regular deep watering, especially through late-summer dry spells, for at least the first season.

When to plant

In central Indiana, early fall and spring are both good planting seasons. Fall planting lets roots grow in cool soil before the ground freezes, and spring planting works if you keep up with summer watering.

Choosing trees and shrubs

Indianapolis is in USDA zone 6b on the 2023 map. Diversity matters more than ever after emerald ash borer: planting many of the same species leaves a neighborhood exposed to the next pest. Native trees such as oaks, maples suited to the site, and smaller natives like serviceberry and redbud are common choices. Indiana's Terrestrial Plant Rule bans the sale and planting of 44 invasive species, including Japanese barberry, wintercreeper, autumn olive, Amur cork tree, white mulberry and several bush honeysuckles. Callery pear isn't on the list, but invasive-species groups discourage planting it.

Pruning basics

Remove dead, damaged, crossing and rubbing branches first.
Spring bloomers such as lilac and forsythia set buds the year before; prune them soon after flowering.
Late winter, while plants are dormant, is a good time for structural pruning on many trees and summer-blooming shrubs.
Skip shearing every shrub into a ball, and never top trees.

Ash trees and big removals

If you still have a large ash, it is either being treated or it's likely declining. Dead ash becomes brittle and dangerous, so removal is a job for a tree service with proper equipment and insurance, ideally with an ISA Certified Arborist. Landscaping companies commonly handle planting and shrub care rather than large removals or work near power lines. Trees in the strip between the sidewalk and street may be in the public right-of-way, and cities including Indianapolis and Carmel have rules for planting or removing them, so check with your city first.

Your county Purdue Extension office can often help identify plant problems. When you're ready, request a landscaping company for planting or shrub care in Indianapolis or a nearby suburb.

Frequently asked questions

What should I plant to replace an ash tree?

Choose a species suited to the site's space, sun and drainage, and avoid repeating what's already common on your street. Many homeowners choose native oaks, maples suited to the site, or smaller natives like serviceberry and redbud.

Is bush honeysuckle illegal in Indiana?

Amur, Morrow's, Tatarian and Bell's honeysuckle are on Indiana's Terrestrial Plant Rule list, which bans selling, trading or introducing them. You can own existing plants, but many homeowners remove them because they spread into woods.

Do I need a permit to remove a tree?

On private property usually not, but trees in the public right-of-way, such as between the sidewalk and street, are often regulated by the city. Check with Indianapolis or your suburb before removing or planting a street tree.
