If you love the herb rosemary, you might be concerned about its black leaves. Here are six reasons why your rosemary plant’s leaves may be turning black.
1. Too Much Water
Rosemary plants don’t like to sit in wet soil. If the leaves are turning black and mushy, it’s a sign that the plant is getting too much water. Make sure to let the soil dry out between watering sessions, and consider moving the plant to a pot with better drainage.
2. Not Enough Sunlight
Rosemary thrives in full sun, so if it’s not getting enough light, the leaves will start to turn black. Move the plant to a sunny spot and see if that makes a difference.
3. Fungal Disease
Fungal diseases can cause rosemary leaves to turn black and drop off the plant. If you see any other signs of disease such as mold or mildew on the plant, treat it with an appropriate fungicide according to label directions.
If you notice your rosemary plant’s leaves turning black, it could be due to a few different reasons. Here are 6 possible explanations:
1. Too Much Water
Rosemary plants prefer well-drained soil and will not do well if the roots sit in water for too long. If you think your plant is getting too much water, try letting the soil dry out completely before watering again.
2. Not Enough Sunlight
Rosemary plants need at least 6 hours of sunlight per day in order to thrive. If the leaves are turning black, it could be a sign that the plant is not getting enough light. Try moving it to a brighter spot and see if that makes a difference.
3. Over-Fertilizing
It’s important not to over-fertilize rosemary plants, as this can cause leaf burn which can lead to the leaves turning black. Stick to using a light fertilizer every few weeks and discontinue use if you notice any leaf burning starting to occur.
4. Pest Infestation
If your rosemary plant is infested with pests, such as aphids or spider mites, they can cause the leaves to turn black. Inspect the plant carefully and treat with an appropriate insecticide if necessary.
Why Is My ROSEMARY PLANT DRYING? 🌿 (3 REASONS and How to AVOID IT)
Is Rosemary Bad When It Turns Black
When you see rosemary turning black, it’s a sign that the herb is no longer fresh. While it won’t hurt you to consume rosemary that has turned black, it will not taste as good as when it was fresh. The black color is caused by oxidization and means that the essential oils in the herb have begun to degrade.
If you want to use rosemary that has turned black, try chopping it up finely so that its flavor is more concentrated. Otherwise, throw it out and get some fresh rosemary from the grocery store.

Is Black Rosemary Safe?
Yes, black rosemary is safe. This variety of rosemary is actually a hybrid of two other varieties – English and Italian – and was created by growers in California. The black leaves of this plant are due to a pigment called anthocyanin, which is also found in blueberries and other dark-colored fruits and vegetables.
There is no difference in taste or safety between black and green rosemary.
Why Does My Rosemary Look Like It’S Dying?
If your rosemary plant is wilting, yellowing, or otherwise looking unhealthy, there are a few possible explanations. First, check to see if the soil is too dry. Rosemary plants need well-drained soil and plenty of water, so if the soil feels dry to the touch, give your plant a good watering.
If the soil is wet or soggy, however, that could be causing root rot, which will kill the plant. Make sure you’re not over-watering!
Another possibility is that your rosemary plant isn’t getting enough sunlight.
This herb loves full sun and needs at least 6 hours of direct sunlight each day in order to thrive. If it’s growing in a shady spot, it may not be getting enough light and could start to die back. Move it to a sunny location and see if that helps revive it.
Finally, pests could also be causing problems for your rosemary plant. Check for signs of Aphids or other sucking insects on the leaves and stems. These pests can weaken plants and make them more susceptible to disease.
If you see any pests on your plant, treat them with an insecticide designed for use on edible plants (be sure to follow the directions!).
If you’ve ruled out all of these possibilities and your rosemary plant is still dying, unfortunately it’s likely that there’s no saving it at this point.
What Does Overwatered Rosemary Look Like?
If you’re wondering what overwatered rosemary looks like, wonder no more! This helpful guide will show you exactly what to look for.
Overwatered rosemary plants tend to have wilted, yellow leaves.
The stems may also be soft and spongy to the touch. You may notice that the plant is not producing as much new growth as it normally does.
If you think your rosemary plant is overwatered, the first thing to do is check the soil.
It should be moist, but not soggy or waterlogged. If the soil is too wet, try removing the plant from its pot and allowing the excess water to drain away. Then replant in fresh, dry soil.
If your plant is still showing signs of distress after being repotted, it’s possible that it has root rot. This can be caused by extended periods of wet or humid conditions. If you suspect root rot, take a close look at the roots of your plant.
They should be white or cream-colored. If they are brown or black, this is a sign of root rot and your plant will likely need to be replaced.
Why are the Leaves on My Rosemary Plant Turning Brown?
If you notice the leaves on your rosemary plant turning brown, it could be due to a few different reasons. One possibility is that the plant is not getting enough water. Make sure to check the soil moisture levels and water accordingly.
Another possibility is that the plant is getting too much sun exposure. Try moving it to a location with more shade. Finally, brown leaves can also be a sign of pests or disease.
Inspect the plant carefully for any signs of insects or fungal growth and treat accordingly.
Conclusion
There are a few reasons why rosemary leaves might turn black. One reason is that the plant isn’t getting enough water. Another possibility is that the plant is stressed due to too much or too little sunlight.
Additionally, rosemary leaves can turn black if they’re exposed to cold temperatures. Finally, over-fertilizing can also cause rosemary leaves to turn black.
