Keep soil consistently moist but not waterlogged. Allow the top layer of soil to dry slightly between waterings.
Well-drained
50% intensity
Moderate temperatures
50% intensity
Prefers temperatures between 15-25°C during the growing season. Can tolerate cooler temperatures in winter dormancy.
Light feeding
25% intensity
Feed with a balanced fertilizer in spring. Avoid over-fertilization.

Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Aristolochia macrophylla prefers consistent moisture. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot. In hotter, drier weather, increase watering frequency.
Reduce watering slightly during the dormant winter period.
Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Pruning can also be done to control size and shape, or to encourage denser growth.
For vigorous vines, occasional thinning out of old wood can improve air circulation and flowering.
Easily propagated from seed sown in autumn or spring. Stratification may improve germination rates.
It can also be propagated from semi-hardwood cuttings taken in summer and rooted in moist, well-drained soil or a propagation medium. Layering is another effective method for increasing plants.
Young plants may need repotting every 1-2 years into a slightly larger container.
Mature plants generally prefer to be slightly pot-bound and rarely require repotting, though top-dressing with fresh soil annually can be beneficial. Repot in spring before the growing season begins.
