Fertilizing Hibiscus Trees for Maximum Blooms: Sun, Water, Feed

Eight hibiscus trees in concrete containers. Goal: maximize blooms.

Non-Negotiables

Full sun: Every photon counts. No fertilizer compensates for shade.
Water: Thorough deep soakings. Let dry between. Mulch to reduce evaporation. Never let hibiscus go thirsty.
Fertilizer: Room-temp water + dilute fertilizer every watering. Monthly "Bloom Buster" (10-52-10) for bud set. Balanced liquid in between.

Pest Watch

Spider mites love heat. Best control: release predatory ladybugs at base. They hunt eggs/nymphs relentlessly.

Winter Note

Tropical hibiscus drops leaves below 10-hr days. Keep in sunniest window, water sparingly, no fertilizer. Watch for whitefly—spray insecticidal soap weekly if seen.

Location, water, feed—in that order.
