Watering a little every day is the best way to water a garden.
Contested
Watering a little every day usually isn't best — it keeps roots shallow and thirsty, so plants cope worse when it's hot. For established plants, water deeply and less often, and let the top of the soil dry between soakings. The exceptions are real: seedlings, new transplants, and containers dry out fast and may genuinely need water daily.
What is actually known
For most established in-ground plants, a light daily sprinkle is the wrong default. It wets only the top of the soil, so roots stay shallow chasing that moisture — which leaves the plant less able to find water and more stressed the moment you miss a day or a heatwave hits. Deep, less frequent watering soaks the root zone and draws roots down, building a more resilient plant, and it loses less to evaporation. There are real exceptions the rule has to name: seedlings, new transplants, and containers dry out fast and often do need daily (or more) water. The honest guide isn't a fixed schedule at all — it's soaking deeply, then letting the top of the soil dry before the next deep water, adjusted to your soil, weather, and crop.

what this rests on - 2 pointers
frequent shallow watering keeps roots near the surface and reduces drought resilience
while deep infrequent watering draws roots down and loses less to evaporation; seedlings/transplants/containers are genuine high-frequency exceptions; extension irrigation guidance
