Dendrobium Recovery from Aphids & Miltonia Bud Blast Mystery

Dendrobium Aphid Infestation Resolved

A grower identified aphids as the cause of discolored, dying dendrobiums. Treatment with Orthenex spray restored healthy green growth. Increased feeding helped recovery.

Miltonia Buds Won't Open

A Miltonia produces multiple spikes full of buds that abort before opening. Two likely causes:

• Insufficient warmth: Move to where day temperatures reach the low 70s°F (low 20s°C).
• Ethylene gas: Ripening fruit nearby releases ethylene, which kills buds. Remove fruit from the growing area.

Addressing these factors should allow buds to mature and open.
