Both species prefer similar growing conditions (partial shade, moist soil), leading to intense competition for resources like water and nutrients. Their root systems can become intertwined, hindering growth.

Aphids

Small, soft-bodied insects that suck sap from leaves and stems, causing leaf curling, yellowing, and stunted growth. They excrete honeydew, which can attract sooty mold.

Spider mites

Tiny arachnids that feed on plant sap, causing stippling, yellowing, and webbing on leaves. Severe infestations can weaken the plant significantly.

Steps:

    • Collect mature seeds in autumn.
    • Sow seeds in a seed tray with moist seed-starting mix.
    • Keep the tray in a warm, humid environment until germination.
    • Once seedlings are large enough, transplant them into individual pots.
    • Take semi-hardwood cuttings in summer.
    • Dip cuttings in rooting hormone.
    • Plant cuttings in a moist growing medium.
    • Cover with a plastic bag to maintain humidity.
    • Once roots develop, transplant into individual pots.
