Reviving a Declining Calamondin: Aphids and Plant Health

A 19-year-old potted calamondin shows drying, yellowing branch bases, leaf drop, and sticky brown substance on one branch. The cause: aphid infestation weakening the tree.

Recovery Plan

• Control aphids with insecticidal soap, horticultural oil, or neem oil. Spray thoroughly, including leaf undersides.
• Boost plant vitality with a product like Atomic Grow (organic, raises brix/sugar content), making the plant less attractive to pests.
• Prune dead wood and improve cultural care: proper watering, light, and fertilization.

Healthy plants resist pests naturally. Address both the infestation and the underlying stress.
