Daylilies and Agapanthus Recovery: Superthrive Not the Problem, Water Was

Daylilies yellowing/dying, agapanthus not blooming. Followed advice: adjusted sprinklers (were under-watering), plants recovering. Asked if Superthrive overdose caused issues.

Superthrive Verdict

Not harmful, not miracle. Vitamin/hormone supplement—some benefit, overpriced. Won't burn or yellow plants. Your issue was water.

Agapanthus Bloom Fix

• Too much nitrogen → leaves, no flowers. Switch to bloom booster (low N, high P).
• Full sun required.
• Divide crowded clumps every 3–4 years.

Bougainvillea Slow Bloom

Same: full sun, dry between waters, low-N fertilizer. They bloom on stress.
