生病的志愿者茶花:(

EricaW

夏天就开始有些叶子稍黄带斑，以为是太晒才这样没有重视，然后一直也没什么时间打理院子，最近才发现几乎所有叶子都这样了，摘了几片叶子去寺里寻医，员工也没说清楚具体原因，说可能是浇水太多，肥料问题或black spot，我整个冬天都没怎么浇过水，大多数都是雨水养护，肥料也是，以前给旁边的玫瑰施肥的时候会给一点，起码都是夏末初秋的时候了。这里高手云集，特来求医问药，看有没有花友的茶花有过类似情况的，请分享一下解决方案，先谢谢了！

严重安慰一下mm，我的盆栽志愿者是在企鹅岛。
岛上降雨量比较小，叶子没有出现像mm家的这样状况。就是花苞打开比较慢。

如此漂亮的茶花不是开得很好吗？叶片能看出问题？今冬少阳多雨吧？

谢谢MM安慰：）我也觉得今年好像开花挺慢的，花苞长了很久了。MM觉的是雨水多有关系吗，也不知道会不会和这段时间温度低和霜降有关系。

谢谢赏花：）幸好目前来看还不影响开花，但是满树斑驳的叶片不但影响美观，最担心的是怕它生病了。

花儿美～

去问了，人家也不太确定是什么原因。

我的茶树小苗也有叶子发黄，个别有锈斑，我就顺手摘掉了。心愿小苗正在开花，但有些花苞中央不能完全打开，雨水一浇，很快就不行了，美丽打折。mm的志愿者开得很完美。

我家老房子也有茶花，不过从来没有出现这种问题。我帮你问了万能的ChatGTP，还给他看了你发的树叶的照片。 他是这么回答的：

Camellia japonica can be susceptible to several issues that might cause leaf discoloration and spotting. Here are some specific problems that might be affecting your Camellia japonica:

### Possible Causes

1. **Camellia Leaf Spot (Fungal Infection)**
   - Symptoms: Small, round, brown spots that can merge to form larger blotches.
   - Remedy: Remove affected leaves and apply a fungicide specifically labeled for use on camellias.

2. **Camellia Leaf Gall**
   - Symptoms: Leaves may become thickened, curled, and distorted with a green or white coloration.
   - Remedy: Remove and destroy affected leaves. Improve air circulation around the plant.

3. **Canker Disease**
   - Symptoms: Sunken, dark areas on stems and branches, which may lead to leaf discoloration.
   - Remedy: Prune out infected areas, ensuring to cut well below the affected part, and dispose of the prunings. Avoid wounding the plant.

4. **Sunburn**
   - Symptoms: Brown or scorched patches on the leaves, usually on the side exposed to the sun.
   - Remedy: Ensure the plant is shaded during the hottest part of the day. Mulch around the base to keep roots cool.

5. **Water Stress**
   - Symptoms: Yellowing leaves, often with brown edges or spots, due to inconsistent watering.
   - Remedy: Water regularly, keeping the soil consistently moist but not waterlogged. Ensure proper drainage.

6. **Nutrient Deficiency**
   - Symptoms: General yellowing of the leaves with green veins (chlorosis) or brown spots.
   - Remedy: Feed the plant with a balanced fertilizer or one specifically formulated for acid-loving plants like camellias.

7. **Pest Infestation**
   - Symptoms: Presence of insects such as aphids, scale insects, or mites, leading to leaf damage.
   - Remedy: Inspect the plant for pests and treat with appropriate insecticides or organic pest control methods.

8. **Chemical Damage**
   - Symptoms: Leaf discoloration and spots caused by herbicide drift or exposure to other chemicals.
   - Remedy: Ensure that no herbicides or harmful chemicals are used near the camellias.

### Steps to Diagnose and Treat

1. **Inspect the Plant:**
   - Look closely at the leaves, stems, and soil for signs of pests or disease.
   - Check for fungal growth or cankers on stems.

2. **Adjust Watering and Feeding:**
   - Maintain consistent soil moisture.
   - Use a balanced fertilizer appropriate for camellias.

3. **Improve Plant Environment:**
   - Ensure the plant has partial shade and is not exposed to direct, intense sunlight.
   - Mulch to retain moisture and regulate soil temperature.

4. **Prune and Clean:**
   - Remove and dispose of affected leaves.
   - Prune to improve air circulation.

5. **Apply Treatments:**
   - Use fungicides or insecticides as needed, following the manufacturer’s instructions.

6. **Monitor and Maintain:**
   - Regularly check the plant for any recurrence of issues.
   - Maintain good cultural practices to keep the plant healthy.

By following these steps and closely monitoring your Camellia japonica, you can identify and address the specific issue causing the leaf discoloration and spotting.

花是挺漂亮的，所以更加担心它会不会生病了，不希望影响明年的开花。

希望只是这样而已，不会影响来年开花。

地栽了，就天养吧
话说散步时看到别家院里的茶花，叶子也有类似问题，看右上角

对，地栽天养～～
是哦，类似问题；我也想，会不会之前温度低又降霜冻坏了

这种叶子太多了，怕都摘了估计也影响开花和生长，先静观其变吧。

对，正是花季，就先留着叶看看。
