Spearmint spreads aggressively via underground runners, potentially crowding out Salvia longispicata and stealing nutrients.

Aphids

Aphids are small, sap-sucking insects that can cluster on new growth, causing curled or distorted leaves and reduced plant vigor. They also excrete honeydew, which can lead to sooty mold.

Spider Mites

Spider mites are tiny pests that create webs on the undersides of leaves. They suck plant sap, causing stippling, yellowing, and eventual leaf drop.

Steps:

    • Take a 4-6 inch cutting from a healthy, non-flowering stem.
    • Remove the lower leaves, leaving only a few at the top.
    • Dip the cut end in rooting hormone (optional, but recommended).
    • Plant the cutting in a well-draining potting mix.
    • Water gently and cover with a plastic bag or humidity dome to maintain moisture.
    • Place in a bright, indirect light location.
    • Keep the soil consistently moist but not waterlogged.
    • Roots should develop in 2-4 weeks.
    • Once rooted, transplant the cutting into a larger pot or directly into the garden.
