Citrus × aurantium
Both Clausena lansium and Citrus sinensis thrive in similar conditions, supporting each other's growth. Citrus trees are also known to help deter pests, which may benefit the Lansium plant.
Psidium guajava
Common guava
Psidium guajava
Guavas and Lansium plants share similar water and sunlight requirements, fostering a mutually beneficial relationship in a garden bed. They also often have similar pest profiles.

Fig trees can become quite large and their root systems may compete with the Clausena lansium's roots for space and nutrients.

Scale Insects

Scale insects are small, sap-sucking pests that can infest the leaves and stems of the Lansium tree. Infestations can cause leaves to yellow, wilt, and eventually drop. They can also weaken the plant and make it more susceptible to diseases. Proper identification and timely treatment are key.

Aphids

Aphids are tiny insects that suck sap from plant tissues. Initial signs of infestation might include distorted leaves, curling, stunted growth or sticky residue (honeydew) on the plant. Prompt action to control aphids is necessary to prevent further damage.

Steps:

    • Select a healthy stem cutting from a mature plant, approximately 4-6 inches long.
    • Remove the leaves from the lower half of the cutting.
    • Dip the cut end in rooting hormone (optional but recommended).
    • Plant the cutting in a well-draining potting mix.
    • Keep the soil consistently moist but not waterlogged.
    • Place the pot in a warm, humid location with bright, indirect light.
