Rose 'Sonia' Wilting Blooms: High Nitrogen and Disease

Rose 'Sonia' (2ft) blooms last 1 day, then wilt. Aphids treated with garlic/soap then neem. Planted in ground, profuse new growth, but every bud turns brown without opening. Zone 7, east-facing, Miracle-Gro Bloom Booster every 15 days, lawn fertilized monthly. Lower leaves yellow/brown tips.

Diagnosis: High Nitrogen + Disease

  • Stop Miracle-Gro Bloom Booster (high nitrogen)
  • Switch to balanced organic rose fertilizer
  • Apply rock dust, compost, mulch
  • Control overhead watering; allow drying between
  • Spray: 1 cup milk/gallon water (calcium), liquid seaweed several times/week
  • Prune for new growth
  • Switch lawn to organic fertilizer

High nitrogen is the main problem.
