    Windowsill Herbs

    Basil, chives and mint you've harvested

    15 Steps, about 19 minutes each. Anyone with a bright window. No garden, no green thumb, no gardening experience needed.

    1. Chapter 1: Sow and start. Basil and chives sown, mint cuttings rooting in water, a watering routine, and your first sprouts.
    2. Chapter 2: Grow. Seedlings thinned, mint potted in soil, plants fed, and any problems spotted and fixed.
    3. Chapter 3: Harvest. Your first harvests of basil, chives and mint, a bundle of dried herbs, and a meal you cooked with them.
    1. 1
      Sow your basil
      A pot of basil seeds sown in damp seed-starting mix, in your brightest window.

      Basil is one of the easiest herbs to grow from seed indoors. It sprouts in about a week in warm conditions, and a windowsill plant can keep you in fresh basil for months.

      Light is the biggest factor for indoor herbs. Most kitchen herbs need at least 6 hours of direct sun a day. In the Northern Hemisphere, a south-facing window usually gets the most.

      The detail beginners miss is sowing depth. Basil seeds are tiny and need light and warmth to sprout. Cover them with only a thin layer of mix, about 3 to 5 mm. Buried too deep, they may never come up.

      Here's an example. Brightest window found: south-facing, about 6 hours of sun. Seed-starting mix moistened in a bowl until it feels like a wrung-out sponge. A 10 cm pot with drainage holes filled loosely. 10 to 12 basil seeds scattered on top. A thin layer of mix sprinkled over and pressed gently. Misted. Covered with a clear plastic bag to hold moisture. Labeled with the date.

      Right is a labeled pot of damp, not soggy, mix in your sunniest window. Basil likes warmth: keep it away from cold drafts and windows that get chilly at night.
