A word from the amateur gardener:
The issue of support is important. The aristolochia can reach ten meters in 2 or 3 years. On a facade, a trellis supports the plant and allows you to guide it more easily.

For the first 2 years, it is important that the plant never runs out of water.
Then water regularly in the summer, especially in drought conditions where watering may be more intense.
Prune any creepers that have escaped away from their support so that they do not remove light by invading windows and openings. Repeat those that can still be guided.
Mulching can be used during the summer to keep the soil moist longer.
