If your basil plant is looking a little worse for wear, don't despair! With a little love and attention, you can bring it back to life in no time. Here are some tips for reviving a sickly basil plant: Check the roots. If they're mushy or blackened, they may be rotted. Cut away any affected roots and replant the basil in fresh soil. Give it some light. Basil loves sunlight, so make sure it's getting plenty of bright light every day. If it's not, move it to a sunnier spot. Water wisely. Water your basil deeply, but don't keep the soil too wet. Allow the top inch or so of soil to dry out between watering. Fertilize it. Use a liquid fertilizer every few weeks to give your basil a boost. Pruning. Trim back any yellow or brown leaves, as well as any stems that are longer than about 6 inches. This will encourage new growth and make your plant look healthier. With a little TLC, you can get your basil plant looking and feeling better in no time!
