Amaryllis pests and spots: what to check

Record red or brown leaf spots, distorted or wilted foliage, chewed leaves, visible insects, or a soft or damaged bulb on a Hippeastrum hybrid. Compare these signs with normal leaf decline during rest.

Check whether the bulb is actively growing, flowering, or entering rest. Inspect leaf pattern and underside, bulb firmness, roots, how wet or dry the mix is, recent outdoor exposure, and any slugs, snails, or bulb-associated insects.

Check for Hippeastrum red spot, bulb pests such as bulb scale mite or narcissus bulb fly, wet-root or bulb decline, and slug or snail feeding after outdoor exposure. Leaf change during rest is a separate possibility.

Keep a wet or soft bulb out of further saturation, separate an obviously affected pot, and inspect for insects or chewing before selecting control. Treat slug damage on a plant that has been outdoors separately from problems on an indoor forced bulb.

After one matched watering, isolation, or exposure change, monitor new leaves and the bulb for continuing spots, chewing, distortion, or softening. Ongoing spread calls for renewed identification, not repeated watering changes. Recovery time varies.

This page covers Hippeastrum species, cultivars, and common indoor amaryllis material, not one named hybrid. Spots alone cannot confirm red spot, a bulb pest, or outdoor mollusk damage, and this advice does not apply to Amaryllis belladonna.
