Identification and Treatment Guide

Updated: June 11, 2022

Crocus plants are a great addition to any garden or landscape. They are easy to grow, come in a variety of colors, and have a long blooming season. Unfortunately, like any plant, crocuses are vulnerable to pests that can damage or kill them. In this article, we will discuss the most common crocus plant pests, how to identify them, and the best ways to treat and prevent infestations.

Identification of Crocus Plant Pests

Aphids

Aphids are small, soft-bodied insects that suck sap from plants. They are usually found on the undersides of leaves or on new growth. Aphids can be green, black, brown, or red.

Spider mites

Spider mites are tiny arachnids that feed on plant sap. They are hard to see with the naked eye but can cause severe damage to crocuses if left untreated. Spider mites often produce webbing around the plant as they move from leaf to leaf.

Thrips

Thrips are slender insects that feed on plants by sucking out cell contents. They can cause distorted growth and discoloration on crocus leaves and petals. Thrips are usually light brown or yellow and have wings.

Whiteflies

Whiteflies are small insects that look like moths. They feed on the sap of plants and can cause leaves to turn yellow and fall off. Whiteflies produce a sticky substance called honeydew that attracts ants and can lead to fungal growth.

Treatment of Crocus Plant Pests

Natural remedies

There are several natural remedies you can use to treat crocus plant pests:

  • Spray affected plants with a strong jet of water to dislodge insects.
  • Mix 1 tablespoon of dish soap with 1 quart of water in a spray bottle and apply directly to plants.
