Bare patches in lawn

My lawn has bare patches. I put some grass seeds in April and one big patch has grass now. However as it has not rained, new bare patches are developing. I put compost on those bare patches and also grass seeds on it. I water it regularly. On one of the corner I put cucumber seeds in April but when there was no germination I put grass seeds in that area as well ( last week). The two photos attached are of two corners of the garden. Should I wait n see? What else can be done?

 

Wait and see is the gardener’s motto.
