Protection of the Bignone with tendrils in winter

If this climbing plant is hardy, it appreciates some protection measures against the cold in winter.

Also protect the stump against the cold by spreading a thick mulch of shredded branches and dead leaves at the foot of your plant in the fall.

Fertilizer

Bignonia capreolata blooms best in rich soil. Bring mature compost to the foot of this climbing plant at least twice a year, in spring and at the beginning of autumn, so that it produces a greater quantity of flowers.

How to prune the persistent ridge?

During the summer, after the end of flowering, roughly prune your bignone capreolata with shears to remove all the faded flowers and balance its silhouette.

How to make a cutting of Bignonia capreolata?

Cut your chocolate bignone in July from the ends of young shoots about 10 cm long. Stew them. Optimum rooting is achieved the following spring.
