The extreme heat added to the lack of water can be terrible for the plants, fortunately you have been very aware of their watering, that is important. I think it would be advisable to additionally put a drip system with some bottles, which gives them some humidity throughout the day, so that they have a little water between morning and night. Beautiful your garden. Greetings.
El calor extremo sumado a la carencia de agua pueden ser terribles para las plantas, afortunadamente has estado muy pendiente de su riego, eso es importante. Creo que sería recomendable, ponerles adicionalmente un sistema de goteo con unas botellas,que les brinde algo de humedad a lo largo del día, de forma tal que dispongan de un poquito de agua entre la mañana y la noche. Hermoso tu jardín. Saludos.
