Basil is an annual herb with various varieties, such as Italian, Thai, and Holy Indian basil. It typically wants to “bolt” or go to flower quickly in hot weather, signaling the transition from vegetative (leaf growth) to reproductive (flower and seed growth). To revive basil with yellow leaves, scale back the watering, plant basil in pots with drainage holes in the base, empty saucers and trays underneath basil pots regularly, and re-pot basil if in a small pot.
There are several causes of yellowing basil leaves, such as improper watering, fungal disease, pests, and lack of nutrients. Overwatering is the quickest way to kill a basil plant, and it can also cause root rot. To fix this issue, stop watering, move the pot to a sunnier location, and feed it with a balanced 10-10-10 fertilizer.
Poor drainage can also lead to root rot and yellowing of leaves. Loosen compacted soil with aged compost or sand prior to planting, pick a few basil leaves off the plant, and sprinkle a little diatomaceous earth around your plants. Yellow leaves may signal light deprivation, so aim for 6-8 hours of direct sunlight daily, adjusting the plant’s position as needed to dodge the shade. Basil prefers bright sunlight for six to eight hours per day. Basil grown indoors will likely need artificial light during the winter, ideally.
Yellowing leaves can often mean the basil needs some sort of nutrient application, like a balanced fertilizer (10-10-10). With a few adjustments to how you grow basil, you could salvage the plant’s health and growth.

How do you save overwatered basil?
In order to salvage an overwatered basil plant, it is necessary to reduce the frequency of irrigation and permit the soil to become sufficiently dry. In the event that the basil plant’s roots have not sustained significant damage, there is a possibility of recovery. It is recommended that any yellow or wilted leaves be removed in order to encourage new growth.
Does basil like full sun?
Basil thrives in full sun, requiring 6-8 hours of direct sunlight per day for optimal flavor and growth. For indoor plants, place them in a south or west-facing window. Basil can live outdoors in California from March to October, but winters are not suitable. Overwintering potted basil indoors is possible with a sunny window. Soil should be loose, well-draining, and mixed with organic compost for improved nutrient levels and moisture retention. Pots with drainage holes can help prevent old water from collecting. However, direct sun and hot summers may cause moisture to dry up quickly.
How to rejuvenate a basil plant?
The speaker is preparing to prune the flowers, removing those that are coming off and trimming those that require it. Some flowers will naturally come off without the need for trimming.
How to tell if yellow leaves are from overwatering or underwatering?
Overwatering can be identified by yellowing leaves, wilting plants, and edema. Yellowing leaves, particularly in younger ones, indicate excess water. Wilting plants, on the other hand, feel soft and mushy due to rotting roots inhibiting water uptake. Edema, a condition where cells in leaves burst, can be a sign of overwatering. Overwatering can cause blisters or lesions, making it crucial to address these issues to ensure proper water management.
How do you bring basil leaves back to life?
To prepare herbs for sourdough starter, first prepare an ice bath by filling a large bowl with cold water and ice. Cut off the stems and remove any bruised or damaged leaves. Submerge the picked herbs into the ice bath and soak for 15-20 minutes until they perk up. Drain the herbs in a colander. This simple method can help prevent waste and ensure proper storage of herbs. Regularly feed the sourdough starter and cut off the stems of parsley, discarding any bruised or damaged leaves.
Can a yellow leaf turn green again?
Yellowing leaves in indoor plants can be caused by overwatering or underwatering, which can lead to the loss of chlorophyll and prevent the plant from turning green again. To fix this issue, remove the leaf using a sterile cutting tool and focus on healthy leaves. If the plant regains its health, new leaves may fill in during the next growing season. It’s important to be patient with plants and eliminate common reasons for yellowing leaves. Checking the soil in the pot can help diagnose the issue. Overwatering or underwatering are common culprits, and only water as much as the plant needs.
What does overwatered basil look like?
Basil plants can suffer from overwatering, which can result in brown or black spots on leaves, yellow leaves near the base, and wilted stems. To prevent this, let the plant dry out before watering again and reduce watering frequency in the future. Underwatering can result in wilted, droopy plants with brown and crispy leaves and dry soil. To prevent this, water basil plants in the morning and direct water to the soil to keep leaves dry. For a sturdy root system, water basil plants slowly for a longer period to ensure water gets deep into the soil.
Add compost to the soil and apply a layer of mulch to prevent soil drying out quickly. Grow basil in well-draining pots and allow excess water to drain away before placing the plant back on its saucer. Soil moisture meters can help avoid overwatering or underwatering basil plants. Frequent travelers may want to invest in a drip irrigation system or self-watering planters to keep their basil well-watered while away.
To determine the need for water, feel the soil line and determine if plants with dry or soggy soil need more or less water. If root rot has set in, take cuttings from the plants and propagate them in water or soil.
How often should basil be watered?
Basil requires approximately 1 inch of water per week to maintain its moisture and roots. It grows best in containers, which need more frequent watering to prevent soil drying out. Watering should be done early in the morning. Basil is a vigorous grower that requires little to no fertilization, and too much can harm its flavor. If you choose to add fertilizer, it should be light twice a season. For pot plants, a weak liquid solution every 3 to 4 weeks is needed to compensate for nutrients washed away by frequent watering. Pinching back leaves from the tips of the basil plant when it has two sets of true leaves encourages full and bushy growth.
How do you fix yellow leaves on basil?
Basil leaves turning yellow can be caused by various factors, including overwatering, nitrogen deficiency, and diseases like Downy mildew, Fusarium wilt, and root rot. Overwatering can cause yellowing leaves, which can be a sign of a nutrient deficiency. To prevent this, keep the leaves dry and ensure good air circulation. Fusarium wilt is a soil-borne disease that can cause yellowing leaves and is highly contagious. If you notice this issue, dispose of the plant before it spreads.
Root rot is difficult to diagnose, but overwatering is a primary culprit. Once the season is over, amend the soil or adjust the landscape to improve drainage. By addressing these issues, basil leaves can return to their original color and health.
Does basil need direct sunlight?
Basil thrives in full sun, requiring 6-8 hours of direct sunlight per day for optimal flavor and growth. For indoor plants, place them in a south or west-facing window. Basil can live outdoors in California from March to October, but winters are not suitable. Overwintering potted basil indoors is possible with a sunny window. Soil should be loose, well-draining, and mixed with organic compost for improved nutrient levels and moisture retention. Pots with drainage holes can help prevent old water from collecting. However, direct sun and hot summers may cause moisture to dry up quickly.
Should basil be watered every day?
Basil requires approximately 1 inch of water per week to maintain its moisture and roots. It grows best in containers, which need more frequent watering to prevent soil drying out. Watering should be done early in the morning. Basil is a vigorous grower that requires little to no fertilization, and too much can harm its flavor.

📹 Why Basil Leaves Turn Brown – Garden Quickie Episode 117
Why Is My Basil Turning Brown? I get this question all the time and even after growing this favorite herb for 12 plus years, I still get …
Mine turned brown for a fourth reason, which is overfertilization. I added too much nitrogen fertilizer too quickly. This caused the leaves to scorch, since fertilizers are salts and will interfere with water uptake. I had to take my basil outside and flush fresh water through the pot several times, then clip off the damaged leaves. The plant should recover, but it may take some time.
That’s what I have right now they all brown and have falling leaves, 😢and yes I’m not home 12 hours cuz of my new job baby sitting 😬 so all my plants are neglected. I’m only home on weekends, now I’m so sick and it’s too cold outside and in 2-4 days we have rain so I’m just waiting for the right day to plant all my winter crop and hopefully I get to harvest them on time 😬😊👍 thanks Jeff it’s nice to watch and catch up some of your articles I missed.
I can’t seem to grow herbs outdoors to save my life! They don’t seem to do well transplanted in the ground. First they get stunted and then dry up and die regardless of watering enough but not too much. They never seem to develop a good root system. I’m thinking now that I might either put them outdoors only in fabric pots with all commercial soil, or keep them indoors. It may bee that the mix of the native soil and compost, peat and worm castings is still too heavy or dense.
How do you tell the difference between fusarium wilt and other factors? Mine kind of look like yours. They aren’t really wilting but they do have brown and yellow on the lower leaves and I think the leaf size is stunted and more crinkled than it should be. They are growing very densely and not spreading out much. I pruned some off jut in case it needed more air flow.
I had this May purchased 4 identical sized Amazil Basil plants, and put each into a different container on my patio in the same location. Two got a brown spot on the stem about 1″ from the soil and slowly died. The other two are alive and no sign of brown spots on the stem. There is no spots on the leaves either. What killed them?
