Ever heard you shouldn’t water tomatoes in the sun? That’s one gardening myth that needs pulling up by the roots.🍅
This same old wives’ tale gets thrown at peppers, cucumbers, courgettes, beans, and leafy greens too, but there’s still zero science behind it.
Leaf scorch is almost always down to drought stress, disease, or nutrient issues, not a few droplets of water acting like tiny magnifying glasses on your plants.
In commercial nurseries and market gardens, growers routinely water from above, even in full sun, because the real risk is not watering soon enough when plants are wilting.
Whether it’s tomatoes, peppers, squash, brassicas, or salad beds, the priority is keeping the soil consistently moist so roots don’t swing from bone-dry to soaked.
So if your veg are flagging in the heat, water them—top down, in full sun if needed—because consistent hydration beats garden myths every time.
