Hydrangeas are a beloved Southern staple, gracing gardens with their stunning blooms. But even these low-maintenance beauties can suffer if we make some common mistakes. To keep your hydrangeas thriving and blooming year after year, here are eight key things to avoid:
1. Pruning Blunders
Pruning is essential for hydrangeas, but it’s all about timing and technique. Overenthusiastic shearing can leave you with bare stems come summer. Instead, focus on removing dead wood and shaping unruly branches. More importantly, prune at the right time:
- Summer: Prune once-blooming varieties like French hydrangeas, oakleaf hydrangeas, and mountain hydrangeas.
- Winter: Prune smooth hydrangeas and panicle hydrangeas. Reblooming French hydrangeas can be pruned in summer or winter.

2. Sun vs. Shade: Finding the Perfect Balance
Location is key for hydrangeas. While that French hydrangea might look perfect next to your mailbox, full sun exposure can scorch blooms. Here’s a quick guide:
- French & Bigleaf Hydrangeas: Thrive with morning sun and afternoon shade, especially in hot summers. No blooms in full shade.
- Oakleaf Hydrangeas: Prefer shade and won’t bloom in full sun.
- Panicle Hydrangeas: Love the full sun and won’t bloom in shade.
Remember, every hydrangea variety has different needs!
3. Soil SOS: Setting the Stage for Success
Hydrangeas are particular about their soil. Avoid dry, rocky areas and plant them in well-drained, loamy soil rich in nutrients. Additionally, the soil’s pH can affect bloom color. For best results, research your specific hydrangea variety’s needs.
4. Big Tree Blues: Avoiding Competition
Hydrangeas need their space to thrive. Planting them under a large tree creates competition for water and nutrients. Find a spot where your hydrangea can be the star of the show!
5. Watering Wisdom: Finding the Right Balance
French hydrangeas are thirsty plants and might need daily watering in hot, dry weather. Other varieties, like Limelight and Pee Gee hydrangeas, are more drought-tolerant. The key is to find the watering balance that keeps your hydrangeas consistently moist but not waterlogged.

6. Fertilizer Frenzy: Less is More
Don’t go overboard with fertilizer! Too much can backfire, causing fertilizer burn and hindering blooms. A slow-release fertilizer or a combination of organic materials like peat moss, compost, and sulfur is the way to go. Apply fertilizer around the base of the plant, avoiding direct contact with roots.
7. Keeping Your Hydrangeas Healthy: A Clean and Clear Zone
Just like planting under trees, letting weeds grow around your hydrangeas steals precious nutrients. Additionally, fallen leaves create a breeding ground for pests and diseases. Regularly remove weeds and clear fallen leaves to keep your hydrangeas healthy. In spring, prune the leaves at the base of the plant to encourage new growth. However, avoid removing leaves from old wood bloomers, as this prevents new blooms next season.
8. Chasing Rainbow Dreams: Accepting Natural Beauty
The allure of colorful blooms might tempt you to manipulate hydrangea flower color. However, this is only possible with certain varieties and often involves adding chemicals to the soil, potentially disrupting the plant’s balance. Embrace the natural beauty of your hydrangeas and plant varieties known for the colors you desire.
