Timing Is Everything: The Secret to Shrub Success Lies in When You Plant

When it comes to landscaping investments, few decisions impact your shrub’s long-term health and survival as much as choosing the right planting time. Fall is the best time to plant new trees and shrubs, and understanding the science behind this timing can mean the difference between a thriving landscape and costly replacements.

Why Fall Planting Delivers Superior Results

Trees and shrubs planted in fall benefit from the combination of warm soil and cool air, which stimulates root growth to help them get established before the ground freezes. This natural advantage gives your plants a significant head start compared to spring installations.

Planting in fall allows these plants to establish root systems that they can then bulk up over the winter. While you won’t see dramatic above-ground growth during the dormant season, the roots are flourishing and will do better than plants just starting to get their roots out during spring.

For homeowners in Delaware County, Pennsylvania, where V. Serrano’s Landscaping operates, spring and early fall are ideal for most landscaping projects in Pennsylvania. Spring installation allows plants to establish during the growing season, while fall planting takes advantage of cooler temperatures and natural rainfall.

The Science of Seasonal Establishment

In South Carolina, fall is the best season to plant shrubs for optimal root growth and successful plant establishment. From the fall through the winter, the above-ground structures of most ornamental plants go dormant and cease growth. However, plant roots continue to grow since the soil does not freeze. These conditions allow shrubs planted in the fall to use the carbohydrates produced during the previous growing season for root growth. When spring and summer arrive, the root growth that has occurred since the fall can better access the necessary water and nutrients for optimum plant growth.

Professional shrub installation timing becomes even more critical when considering survival rates. Research shows that focusing on sapling root moisture and physical protection during planting improved sapling survival by at least 10% (>91% versus 81%) at 4 months.

Optimal Planting Windows Throughout the Year

Fall, winter (soil should not be frozen), and early spring are the best times to plant trees and shrubs. However, timing varies based on plant type and local conditions:

• Fall (September-November): The best time is early-to-mid fall, after the heat of summer has gone. This gives the small tree or shrub enough time to establish a healthy root system before spring
• Early Spring: You can also plant dormant trees and shrubs and cold tolerant annuals as early as April
• Winter: January through March is a perfect time to plant all bare root plants, such as roses and fruit trees. These plants are dormant during this time of year, so they’ll be ready to rise and shine in spring

Factors That Impact Establishment Success

Beyond timing, several factors significantly influence shrub establishment and survival rates. Critical determinants of sapling survival include their vigour and condition when planted, the wetness of the soil into which saplings are planted, the trauma of transplant shock from nursery to natural field soils, and the method and care taken during planting.

Environmental conditions play a crucial role in plant establishment. South and west aspects receive more solar radiation during the day and are warmer and drier, with higher ETs than north and east aspects. Soils on these south and west aspects dry out faster than north and east slopes. In spring, during seed germination, south and west aspects can dry very quickly between rainstorms, reducing the rates of germinating seeds. As seedlings emerge and grow through spring and early summer, temperatures on the south and west slopes continue to rise to very high levels, creating very unfavorable conditions for seedling establishment. Even with planted seedlings, high surface temperatures can damage stems near the ground line, severely affecting seedling survival and establishment.

Post-Installation Care for Maximum Survival

Proper timing is just the beginning of successful shrub establishment. The most important job you will have after planting new shrubs is to keep them well-watered, until fully established… Since the roots will not have spread into the surrounding soil, direct water to the root ball for the first year of growth… Keep your shrubs well watered – they should never dry out completely during their first season.

Since you’re planting in fall, you will need to continue watering your newly planted tree or shrub until the ground freezes. As your trees and shrubs are becoming established, water two or three times a week, adjusting for weather and soil conditions.

Making the Right Choice for Your Landscape

The investment in professional shrub installation pays dividends when done at the right time with proper technique. Professional landscaping typically adds 10-15% to home value, and that’s before you factor in the time you’re not spending on maintenance headaches.

By choosing fall for your shrub installation and working with experienced professionals who understand local conditions, you’re setting the foundation for a landscape that will thrive for years to come. The combination of optimal timing, proper installation techniques, and ongoing care creates the best possible conditions for shrub establishment and long-term success.

Remember, the best time to plant trees, flowers, or any plant is during the dormant season. In North America, this is usually late fall through early spring. While it’s okay to plant during the rest of the year, it will require more maintenance from you in the form of watering, fertilizers, etc. Choose wisely, plant at the right time, and watch your landscape investment flourish.
