I guess the flowers are enjoying the sunshine. They look wonderful, but if exposed to intense heat above 35 degrees celsius, I guess it won't be good.
During hot and dry seasons, they may need shades, and since they are planted in pots, you may try to put them under the shades of trees to protect them against the direct heat from the sun.
Sorry for replying late!
You think there will be intense heat above 35 degrees. Here, the temperature reaches 50 degrees in summer, and after Covid, there have been such changes in the weather that now it suddenly rains anytime and then within a few hours, there is scorching heat again. It is terrible weather, and you're right, plants require shade and water twice a day. Thanks for your comment! :)
