🌱 Preparing Your Garden for Hydrangeas

Creating the right environment is crucial for hydrangea success in North Texas.

Soil Preparation

  • Soil Type: Hydrangeas prefer well-draining, loamy soil rich in organic matter.

  • Soil pH: Aim for a slightly acidic to neutral pH (5.5–6.5). This range supports healthy growth and vibrant blooms.(gardenguides.com)

  • Soil Amendments: Incorporate compost or well-rotted manure to improve soil structure and fertility.

Choosing the Right Location

  • Sunlight: Select a spot that receives morning sun and afternoon shade. This exposure protects hydrangeas from the intense afternoon heat. (splendidgardens.net, gardenguides.com)

  • Protection from Wind: Plant hydrangeas in areas shielded from strong winds to prevent damage to their delicate blooms.

🌼 Planting Hydrangeas

Proper planting techniques set the foundation for healthy hydrangeas.

Planting Steps

  1. Timing: Plant hydrangeas in early spring or fall when temperatures are mild.

  2. Digging the Hole: Dig a hole twice as wide and the same depth as the root ball.

  3. Soil Amendment: Mix the removed soil with compost to enhance fertility and drainage.

  4. Planting: Place the hydrangea in the hole, ensuring the top of the root ball is level with the ground surface.(realsimple.com)

  5. Watering: Water thoroughly to settle the soil around the roots.

  6. Mulching: Apply a 2–3 inch layer of mulch around the base to retain moisture and regulate soil temperature.

💧 Watering and Fertilizing

Consistent watering and proper fertilization are key to hydrangea health.

Watering Tips

  • Frequency: Water deeply once a week, increasing during hot, dry periods.(realsimple.com)

  • Method: Water at the base to avoid wetting the foliage, which can lead to fungal diseases.

  • Soil Moisture: Maintain consistently moist soil, but avoid waterlogging.

Fertilizing Tips

  • Type: Use a balanced, slow-release fertilizer formulated for flowering shrubs.

  • Timing: Apply in early spring as new growth begins.

  • Avoid Over-Fertilizing: Excessive fertilizer can lead to lush foliage with few blooms.

Pruning Guidelines
