Thanks everyone for all the responses. First of all, just clarify the extent of the weather right now. We live in Dubai and I said it's 40C+ but it can be 50C+ these days😅. We thought right away that the heat did all the damage because at around the same time all of our outdoor plants got really dry and yellow (we have some hibiscus & bougainvillea).
So to answer the questions:
*The pot is 35cm wide and 30cm deep, it has drainage holes.
*we got the trees around Feb/ Mar this year.
*My mom takes takes care of the plants, and she said she checks the soil with her finger, and once it feels dry she will water the trees. (She'll water it everyday/ or every other day depending on the temperature).
