Make sure that your plants have enough light
It’s very simple: if you do not give your plants enough light and water, they will die. So, make sure that your plants have enough light and water. In this sense, if your flowers and vegetables are in the garden, you have to plant them in a place where they can receive a lot of light.
Nonetheless, if you have a garden where the sunlight does not persist too long, you should opt for plants that can still grow without too much light, such as spinach, lettuce, radishes and cabbage.
