Usually the catalpa is planted in the period of October or November if we are in the garden, in the harvest of March or April if it is potted vegetation. Its flowering period is expected from May to August, with due exceptions for the different varieties. The fruits, on the other hand, develop in autumn and persist until spring. It is advisable to provide for an accurate but not aggressive pruning of the plant in the period from February to April, in any case before the plant starts its vegetative period.
The catalpa does not need large or frequent watering and reacts well to places or periods of drought. Generally, if it is placed outside, natural watering due to summer or spring rains is sufficient.
