how many hours of sunlight do lavender plants need
Over watering is more of a threat to lavender plants than not giving them enough water. When plants are young, within the first 1 to 3 years, lavender plants will probably need to be watered once per day unless it rains. Lavender plants like at least 6 hours of sun per day, and if it is overcast for a few days in a row, consider watering less. You can always test the soil, by sticking your finger down (3-4 inches away from the root/main stem) to see if the soil is dry.
