Planting & Care
Planting Time
Plant most shrubs in spring or fall when temperatures are mild for best root establishment.
Sun Requirements
Follow each shrub’s sun preference. Most bloom best with the recommended light exposure.
Watering
Water deeply and consistently while establishing during the first 1–2 years. Keep soil evenly moist, not soggy.
Pruning
Prune based on bloom time. Spring bloomers that flower on old wood are usually pruned right after flowering. Summer and fall bloomers on new wood are usually pruned in late winter or early spring.
Fertilizing
Apply slow-release, balanced fertilizer in early spring to support healthy growth and blooms.
Mulching
Add 2–3 inches of mulch around the base to conserve moisture, regulate soil temperature, and suppress weeds.
Special Care Notes
- Endless Summer Hydrangea: Protect buds in harsh winters and avoid heavy late-fall pruning.
- Butterfly Bush: Deadhead spent blooms to encourage more flowers and keep plants tidy.
- Azalea: Prefers acidic, well-drained soil; avoid lime.
- Lilac: Use low-nitrogen fertilizer to promote blooms, not foliage.
- Forsythia: Don’t shear too hard. Prune after flowering to preserve next year’s blooms.
