Use pots with drainage holes and universal substrate, mixed with some sand if the soil is very compact.Plant in an elevated location above the garden to prevent water retention during rainy periods.
Irrigation
irrigation should be moderate and adapted to the climate. It is preferable Let the soil partially dry before watering againTo check the humidity, you can insert a stick and see if it comes out wet or dry.
