Over time, the leaves may then become dry and start to brown completely.Īlthough there is no hope for a plant that is dying of old age, you could choose to propagate your thyme and start the growth of a new plant. Signs that your thyme plant is dying of old age and needs to be replaced include your plant’s rate of growth depleting rapidly, and the stems become woody. Usually, thyme plants will last a maximum of 4-5 years. However, there’s still a time span on how long they live. Thyme plants are perennial, meaning that they come back and regrow every year. If your rosemary beetle infestation has progressed too far to remove the bugs by hand, you can alternatively choose to use a pesticide to remove them.Įnsure that you choose a pesticide that is specifically made for fruits, vegetables, or herbs, to avoid infecting your plant with anything that could be toxic to humans if consumed. This technique may need to be repeated over several days, as new eggs and larvae could be missed. Milder infestations can be treated by simply handpicking the bugs off of the plant. Mature rosemary beetles have recognizable metallic stripes on their backs, which usually come in green and purple colors. Rosemary beetles can be easily identified, so I would suggest keeping a regular eye on your plant so that you can catch these pests in the earlier stages. If left untreated, these pests can even consume all of the leaves on your plant, leaving you with a withered plant made up of mostly stems. It is known to feed and lay its eggs upon the leaves of plants, which can cause visible bite marks in the foliage and disfiguration. One exception however is the rosemary beetle (Chrysolina Americana), which is a common pest amongst herbs and aromatic plants. Thyme is very hardy when it comes to pests and disease, and is rarely affected by anything of the sort. If you are unable to get the required light inside or on a windowsill, I would advise moving your thyme outside for a few hours a day to ensure it receives the sunlight that it needs. If the lack of sunlight is a locational or climate issue, I would strongly suggest purchasing an artificial sunlight lamp that can imitate the conditions that this plant needs. I would personally suggest making sure your plant gets at least 6 hours of sunlight a day, but any more than that is highly recommended.Ī plant that is suffering from too little sunlight should be reintroduced into direct light immediately and moved out of a shady location. Thyme needs as much sunlight as it can possibly get. This is because the heat from the sunlight draws out the natural oils from leaves, which is part of what gives thyme its trademark herby taste. If consumed, you may also notice that your herbs have a much weaker taste than usual. Thyme thrives in hot weather, and without these preferred conditions the leaves will begin to droop and turn yellow. Use a popsicle stick or your finger and press it a few inches into the soil to check for any moisture. The best way to know whether your thyme needs to be watered is by doing a simple touch test. I usually water my thyme every week during the summer seasons, and less during the cooler months. How often you should water your thyme depends on the place’s climate. Getting the watering schedule right is the most important part of preventing root rot. Using a new pot or sterilizing the previous pot is absolutely vital to prevent any fungi from spreading to the plant once again. Next, you can repot your thyme into fresh, dry soil. You should take great care when handling the roots, but don’t panic if any mushy or brown roots break off during the process. Start by removing the plant from the soil and washing any excess soil from the roots.
