Convolvulus arvensis

Field bindweed is a vigorous, climbing vine that can quickly outcompete passionflower for space and resources, potentially shading it and limiting its growth.

Ipomoea purpurea
common morning-glory
Ipomoea purpurea

Morning glories, like bindweed, are aggressive climbers that can smother the passionflower, depriving it of light and nutrients.

Aphids

Small, sap-sucking insects that cluster on leaves and stems, causing yellowing, distortion, and stunted growth. Infestations can lead to the overall decline of the plant.

Spider mites

Tiny arachnids that spin webs on the undersides of leaves, causing stippling, discoloration, and eventually leaf drop. Severe infestations can completely desiccate the leaves.

Steps:

    • Take a 4-6 inch cutting from a healthy stem, ensuring a node (bud) is included.
    • Remove the lower leaves, leaving 2-3 leaves at the top.
    • Dip the cutting in rooting hormone (optional).
    • Plant the cutting in a well-draining potting mix.
    • Keep the soil consistently moist, but not waterlogged.

Neem oil

Effective against aphids and spider mites, neem oil is a natural pesticide that can help manage pest populations.

Fish emulsion

A natural liquid fertilizer that provides essential nutrients for healthy plant growth.
