When it doesn’t rain enough, turn on the spigot. Veggies need water to produce, so watering the garden correctly is crucial in the hot summer. Tomatoes are especially unforgiving if they dry out. Going from dry to wet and back again creates problems like blossom-end rot, which you can read more about below. And that’s not all. Have you seen cracks in the fruit? This happens when water follows a drought, causing the fruit to expand suddenly and split the skin. The way to avoid this is to keep the soil consistently moist. Don’t let it go dry and wet and dry and wet and dry and wet. It’s a spoiler.
