Your mums look lovely! Since your window box is lattice lined with a coco liner, as opposed to a solid container, your plants are more susceptible to drying wind and high temperatures. You will need to check the soil once or twice daily and water if the the soil is dry.
Also you mentioned the pot size. If larger pots will fit in the window box that you could transplant into, that also would give your mums more protection against the elements.
