What causes dried, yellowing leaf tips on osmanthus. First, let's talk about the situation in the picture below! This pot of osmanthus has been grown for quite a long time, and the potting soil was not recently changed. When this happens, it is putting out new buds, the new growth is doing quite well, and the old leaves are degenerating. This is normal, and because of a long period of insufficient water supply in winter, this situation easily occurs. There is no need to worry about it at all; just let it degenerate and care for it normally. Now let's talk about several other causes of this situation in osmanthus.
1. Osmanthus leaves are constantly growing. Older leaves from the previous year are prone to this situation. In other words, it is a kind of metabolism. If your care is very normal and the new leaves are coming out well, you do not need to worry about it; this is normal degeneration. The main sign is that the leaf edges dry out first, then it gradually spreads toward the middle of the leaf, the veins and the petiole, causing the whole leaf to fall off. This is normal.
2. Long-term lack of water in the potting soil and air humidity below what is needed cause dried leaf edges and dried tips. With short-term water shortage and insufficient air humidity, the roots barely supply its growth, and the early sign is that the leaf edges and leaf tips begin to dry out. With severe water shortage, most of the leaves will dry out, and the entire osmanthus may even dry out and die.
3. Root damage causes drying out. Repotting too recently or applying too much fertilizer can damage the roots or burn them. There are many situations that damage the roots: soil that is too dry for a long time damages the roots; watering too much and compacted, waterlogged soil damages the roots; a long period without fertilizer followed by a sudden application of overly concentrated fertilizer burns the roots. All of these situations damage the roots and cause the leaf edges to dry out. You can rule them out appropriately based on your own care.
4. If there are long stretches of consecutive cloudy days, then the sun suddenly comes out with overly strong light, it easily causes the tips of new leaves to dry out, or new buds to wither. After a long period of cloudy days, when the sun suddenly comes out, be sure to provide appropriate shade so it can gradually adapt to the light. Only then will this situation not occur.
When osmanthus has dried leaf edges and dried tips, these are roughly the causes. If you run into this, rule them out appropriately according to your care situation and you can effectively solve it. You can also pay attention to these points while growing it, and this situation will not occur. With good care, osmanthus leaves stay glossy green, and it blooms with especially fragrant flowers every year.
