Aphids

Small, soft-bodied insects that suck sap from the plant. Symptoms include yellowing leaves, stunted growth, and sticky honeydew. They can be found on stems, leaves, and buds.

Spider mites

Tiny arachnids that feed on plant cells, causing stippling and webbing on leaves. Infested plants may appear dry and dusty.

Steps:

    • In the fall, carefully dig up the corms after the foliage has died back.
    • Gently separate the corms from each other.
    • Store the corms in a cool, dry place (e.g., a paper bag) over the winter.
    • In the spring, plant the corms about 2-3 inches deep and 4 inches apart in well-drained soil.
    • Water regularly during the growing season.
