What Shrubs to Plant — and What NOT to Plant — in Fall

By Natalie Carmolli – Proven Winners® ColorChoice® Shrubs

You’ve probably heard it many times: “Fall is a great time to plant.” And it really is! As the temperatures drop and the summer heat fades, the cooler air creates an ideal environment for many shrubs to get established. Plants aren’t stressed by heat, and the soil still holds warmth, encouraging roots to grow steadily even as the tops of the plants slow down for dormancy. Fall planting gives shrubs a chance to focus their energy below ground, building strong roots before the challenges of winter. If your new plantings look a little droopy or lose some leaves after being moved, don’t panic. Many deciduous shrubs naturally shed foliage when transplanted, and in fall, this isn’t a sign of failure, it’s a sign the plant is redirecting its energy to what matters most: root growth. Come spring, your plants will return vibrant and ready to thrive. That said, there are some types of shrubs that should not be planted in fall.

Shrubs to Avoid Planting in Fall

Not every shrub thrives with a late-season start. Some need a full growing season to establish roots before winter - planting too late can do more harm than good. Here are some examples:

• Butterfly Bushes – Butterfly bushes are vigorous summer bloomers that rely on several months of active growth after planting to establish a strong root system. Late planting can leave roots shallow and vulnerable to drying or frost damage.
• Broadleaf Evergreens – Shrubs such as boxwood, azaleas, and rhododendrons keep their leaves year-round. Because they retain foliage, they continue to transpire in winter, which means they lose water through their leaves even when the soil is cold or frozen. Without well-established roots, they can’t replace this water, which can lead to drying out or winter burn.
• Evergreens – Like broadleaf evergreens, needle-leaved evergreens such as arborvitae, juniper, and yew also lose water through transpiration throughout the winter. Planting them late in the season puts them at risk if their roots haven’t had enough time to grow deep and strong.

Fall-Friendly Shrubs to Plant

On the flip side, many deciduous shrubs shine when planted in autumn because they can safely ride out winter in dormancy. Here are a few favorites:

• Smooth hydrangeas like Incrediball Storm Proof™ will happily establish in fall and wake in spring to deliver massive white blooms that stand up to strong winds and heavy rain.
• Panicle hydrangeas thrive when given an autumn head start. Limelight Prime® H. paniculata will reward you the following summer with iconic lime-green flowers on a sturdy, upright habit.
• Colorful Spirea like Double Play® Candy Corn® and Double Play Doozie® add bold fall color and season-long interest. Both are hardy varieties that can hold up to almost any landscape challenge.

Tips for Fall Planting Success

Of course, any new plant will perform best when a few basic steps are followed. Taking time to provide care now can make a big difference in how strong and healthy they’ll be come spring.

1. Water deeply - Newly planted shrubs need consistent moisture to encourage roots to grow deep into the soil. Water several times a week, especially during dry spells, making sure the soil is moist but not soggy. Deep watering helps the roots anchor and supports the plant through its first winter.
2. Plant in native soil - Resist the urge to add amendments like compost or potting mix directly around the root ball. Dramatically different soil can create a “bathtub” effect, causing water to pool around the roots and potentially lead to decay. Planting directly in native soil encourages roots to spread naturally and establish a strong foundation.
3. Mulch generously - Apply a 2–3 inch layer of mulch around the base of your shrubs. Mulch helps regulate soil temperature, retain moisture, suppress weeds, and protect roots from sudden temperature swings during winter.
4. Give them space - Avoid crowding shrubs or planting too close to buildings, fences, or other plants. Adequate spacing ensures good air circulation, which reduces the risk of disease and helps the foliage dry more quickly after rain or dew.
5. Check your calendar - For best results, plant fall shrubs at least 6 to 8 weeks before your area’s average first frost. This gives them time to establish roots, recover from transplanting, and gradually adjust to cooler temperatures before winter sets in.

Bonus Tip: Monitor moisture through fall and early winter – Even as temperatures drop, shrubs still need water until the soil freezes. Check your plants periodically during dry periods and give them a deep soak when needed. This extra attention helps newly planted roots stay healthy and ready for spring growth.

With the right choices, fall planting can give your shrubs a jump start on spring growth. Deciduous shrubs planted now focus energy on root development, emerging stronger and more resilient when warmer weather returns. Giving these hardy varieties time to settle in sets them up for bigger blooms, fuller foliage, and a healthier structure. At the same time, save broadleaf and needle-leaved evergreens for spring, when they have a full growing season to establish roots before winter stress. A little planning now means a garden that’s vibrant, robust, and thriving season after season.
