As summer fades into fall, September brings the perfect conditions for planting trees and shrubs in your landscape. Cooler nights, combined with the still-warm soil, create an ideal environment for roots to establish strong, healthy growth before winter sets in. Plant now, and your trees and shrubs will be ready to thrive when spring arrives!

Why September Is Ideal

  • Cool Nights, Warm Soil – While the air is cooling, the soil still holds the warmth of summer. This balance reduces stress on new plants and encourages vigorous root growth.

  • Less Stress for Plants – Without the extreme heat of July or August, newly planted trees and shrubs can focus on settling into the soil rather than surviving scorching conditions.

  • Better Moisture Retention – Cooler weather means less evaporation, so your plants can make better use of every watering.

  • A Head Start for Spring – By planting now, your trees and shrubs develop roots during fall and early winter. Come spring, they’ll wake up ready to flourish.

Plant with Quality Products

At Crystal Lake Garden Shop, we believe success starts with the right foundation. When planting trees and shrubs this September:

  • Use Coast of Maine Soils – These premium organic soils provide rich, nutrient-dense support for long-lasting plant health. Their natural ingredients improve soil structure and give your trees and shrubs the perfect home to grow in.

  • Feed with Espoma Bio-tone Starter Plus – This trusted organic fertilizer jump-starts root development with mycorrhizae and beneficial microbes. It reduces transplant shock and ensures your plants get established faster and stronger.

Expert Tips for Success

  • Dig wide, not deep – Make your planting hole 2–3 times wider than the root ball, but no deeper. This encourages roots to spread outward into the surrounding soil.

  • Mulch for protection – Add 2–3 inches of mulch around your new planting to lock in moisture, regulate soil temperature, and reduce weeds.

  • Water regularly – Give your trees and shrubs deep, consistent waterings until the ground freezes. This is the single most important step in helping them thrive.
