Keeping plants adequately hydrated throughout the summer is a full time job. Here are some tips and hacks to make life much easier.
Water deeply. Rather than watering a little bit every day, water less frequently but more deeply to encourage deep, strong roots. You could also place an empty plastic nursery pot with holes in the middle of your garden to create a well for easier and deeper root watering. This is especially helpful for plants whose roots go deeper and deeper into the soil, making it harder for the water to reach the plant in dry climate.
Target the roots. Focus on watering the soil surrounding your plants rather than their leaves because wet foliage encourages sun scald and diseases. Puncture holes around the sides of a plastic bottle and stuff a sock in it. Fill the bottle with water and bury it half-way in the garden. Fill with water and screw the cap back on. The sock will absorb and retain the water, slowly distributing it to plants. Unscrew the cap and fill the bottle when needed.
Water in the morning. Watering before noon when your plants need it most will help you avoid water loss to evaporation. And even if the surface looks dry, it doesn't mean there isn't water deeper in the soil. Check the top 6 inches of soil for moisture daily. If it is dry, add more water; if it is still moist, come back later.
