The question of how often water indoor herbs has no single answer that works for all your plants. Different herbs need different amounts of water to thrive in your home. You cannot follow one watering schedule indoor herbs and expect all your pots to do well.
I killed my first rosemary by watering it like my basil plants. Both got a drink every three days on my same schedule. The basil loved it and grew fast in my window. The rosemary turned brown and died within six weeks from root rot I caused by being too generous.
My neighbor made the same mistake with her thyme last year. She gave it water every time she watered her mint. Her thyme rotted away while her mint grew huge. We both learned you have to treat each herb type as its own thing.
That failure taught me to check each of your herbs before watering. Now you should stick your finger 1-2 inches deep into the soil to test moisture. Some of your plants need water while others right next to them can wait another week.
Your rosemary, thyme, sage, and oregano all came from dry climates. They store water in their leaves and roots so you do not need to water them often. These plants want their soil to dry out between drinks. Too much water rots your Mediterranean herbs fast.
Here is a key indoor herb watering guide tip for you. Your bay, oregano, sage, and thyme should dry out between drinks. Let the top inch of your soil go dry before you give these herbs more water.
Your basil and mint take the opposite approach from dry herbs. These plants like soil that stays damp but not soggy in your pots. You should check them every few days and water when your top half inch feels dry. They wilt fast if you let them dry out too much.
Watch for overwatering herbs signs in all your plants so you can catch problems early. Yellow leaves at the bottom often mean you gave too much water. Mushy stems near your soil line signal root rot has started. Fungus gnats flying around your pots tell you your soil stays too wet.
Self-watering pots work great for your thirsty herbs like basil and mint. They keep your soil at the right moisture level without daily attention from you. I use these for my moisture lovers and regular pots for my herbs that like to dry out.
Bottom-watering helps you prevent pest problems in all your herbs. Set your pots in a tray of water for 20-30 minutes and let them drink from below. Your soil surface stays drier this way which stops fungus gnat eggs from living there.
Winter heating dries out your soil faster than you might expect. You need to check your herbs more often when your heat runs. Summer humidity keeps your soil moist longer so you can water less. Adjust your routine as your seasons change to keep your herbs healthy and growing well.
