Basil Looking Droopy? 7 Genius Ways to Revive It and Help It Last Even Longer
Basil is one of the tastiest herbs in any kitchen garden, but these delicate plants can wilt if they're not receiving the proper care. Here's why basil plants can be susceptible to wilting, plus seven ways to protect your plants and enjoy basil in your garden all summer long. Why Basil Plants Wilt So Easily Basil is a tender herb that's pretty easy to grow with the proper care and conditions. But if the plant isn't getting its needs met, it may wilt or show other signs of distress. Probably the most common reason basil plants wilt is underwatering, especially in very hot, sunny weather. Overwatering can also cause plants to wilt and leaves to yellow and eventually fall off. Transplant shock, in which damage to roots makes it difficult for the plant to take up water, can also cause basil to wilt. Overharvesting, or taking too much of the plant's foliage at once, can contribute to stunted growth and can eventually harm or kill the plant. Plant diseases can also contribute to basil wilting. Fusarium wilt is a fungus that will stunt sweet basil plants once they reach around 8 to 12 inches tall. Symptoms include browning stems and wilting, curled, or yellow leaves.1 Another disease that can cause basil to wilt is called basil downy mildew. Leaves will wilt or curl and turn yellow, with a fuzzy purple or gray growth on the undersides of leaves. As with fusarium wilt, sweet basil varieties are more susceptible than Thai purple or other specialty basils.2 Want more gardening tips?

If growing basil in a container, choose a pot with a drainage hole and add perlite to the standard potting mix for additional drainage. Transplant carefully: If possible, transplant basil seedlings or potted plants on a cool, overcast day or later in the afternoon to avoid exposing the delicate plants to hot, sunny conditions. Give plants enough space between them to allow for airflow. Water appropriately: Water basil regularly to keep the soil evenly moist. Do your best to water the soil directly, keeping the leaves dry and reducing the risk of plant diseases. Mulch around plants: Add a few inches of organic mulch, such as salt hay or shredded straw, to garden beds and around the base of basil plants. This will help the soil stay moist and reduce weeds. Avoid overharvesting: Basil plants are ready to harvest once they're about 8 inches in height. Avoid removing more than a third of the foliage at any one time. Harvest from several plants so that the others have time to regrow. Plant disease-resistant varieties: To minimize the risk of disease, look for resistant varieties of sweet basil like 'Aroma-2', 'Obsession', 'Prospera', and 'Eleonora'.1 Rotate crops in your garden: Avoid planting basil or other susceptible plants for three years after plants grown there were affected by diseases like fusarium wilt or basil downy mildew. How to Revive a Wilting Basil Plant A thirsty, wilting basil plant should bounce back after a deep watering. Remove any yellow, brown, or dead leaves so the plant can concentrate its energy on new growth. If you suspect your wilting basil plant is overwatered, allow the soil to dry out completely, or consider repotting it in fresh soil and only water going forward when the soil surface has just begun to dry out. Unfortunately, basil plants that show signs of disease can't be treated. Instead, harvest any unaffected plants or leaves and use them quickly. Bag up diseased plants and plant parts and throw them in the trash to avoid spreading the disease to other plants.
