Yes, basil can grow indoors and do very well with the right setup. The key to making basil grow indoors is enough light from a bright south-facing window or a grow light. Get the lighting right and your indoor basil will thrive year-round.
One of the top indoor basil growing tips is to add a grow light. When I first set up a small LED clamp light over my kitchen basil, the change was huge. My windowsill plant grew slow and pale with thin leaves. The grow-light plant put out thick dark green leaves and grew twice as fast. The whole setup cost me about $30 and paid for itself in fresh basil within a month.
Your indoor basil needs 10 to 12 hours of light each day. Keep the room between 65 and 75°F (18-24°C) for best results. You also need good air flow around the plant. Still, damp air leads to mold on the leaves. A small fan on low speed or an open window on mild days gives your basil the breeze it needs. These indoor basil growing tips make the biggest impact on your results.
Gardening Know How and Bonnie Plants both say a south or west window is the bare minimum for indoor basil. Most windows in cold climates fall short during winter, which is why grow lights help so much. Use a well-draining potting mix in your containers rather than garden soil. Garden soil packs down tight in pots, holds too much water, and can bring pests inside your home.
Growing basil inside means you water less often than outdoor plants. There's no wind or hot sun drying out the pot. Check the soil with your finger and water only when the top inch feels dry. Feed with a half-strength liquid fertilizer every 2-3 weeks to keep leaves big and full of flavor.
Pick compact types like bush basil or Genovese for growing basil inside. Tall types get leggy and flop over in pots. Use containers with drain holes and turn the pot a quarter turn each week so all sides get even light. Pinch the top of each stem every week to keep your plant bushy and delay flowering.
Air flow is something most indoor growers forget about. Basil leaves that stay damp in still air get brown spots and mold fast. I lost my first indoor basil plant this way before I figured out the fix. Now I run a small desk fan near my plants for a few hours each day. The moving air keeps leaves dry and helps stems grow stronger too.
You can also start indoor basil from cuttings rather than seeds. Snip a 4-inch stem from a healthy plant, strip the bottom leaves, and place it in water. Roots will show up in about a week. Pot it up once roots reach two inches long. This method gets you a producing plant much faster than waiting for seeds to sprout and grow.
Your indoor basil won't match a full garden bed in output. But two or three well-kept pots will give you enough fresh leaves for weekly cooking. Start small, follow these steps, and you'll have fresh basil on your counter all winter long while your garden rests outside.
