Mango browning leaves question

[wookieboogie]

Hello everyone, I have mango tree planted in 35L planter bag. This tree already planted in this bag for 1 month+ and suddenly there are some old leaves turning brown. What do you think can be the problem of this browning?
About location, I live in jakarta with high noon temp around 35°c, this tree receive full sunlight. Watered every morning, planted in well-drain soil (mix of compost, soil, rice husk)

It needs to be in afternoon shade at those temperatures, in a deep deep pot with compost and watered frequently. Grow bags lose moisture way too rapidly to be good for planting a tree that needs a lot of moisture. I would just scrap that one, it's pretty stressed and at a young age it will be less work to just start another from seed.

Hi there! It sounds like you're doing a great job caring for your mango tree, but I can understand your concern with the browning leaves. A few factors could be contributing to this issue:

1. Watering: While you’re watering every morning, it’s essential to ensure that the soil isn’t becoming waterlogged. Mango trees prefer their soil to dry out a bit between waterings. Check the moisture level a couple of inches down in the soil; if it's consistently wet, you might want to reduce the frequency of watering or ensure your planter has good drainage.
2. Heat Stress: With the high temperatures in Jakarta, your mango tree could be experiencing heat stress. While they do enjoy sunlight, extreme heat can cause older leaves to brown. If possible, consider providing some afternoon shade or using a shade cloth during the hottest part of the day.
3. Nutrient Deficiency: The browning could also be a sign of nutrient deficiency. Even with a well-draining mix, it’s a good idea to fertilize with a balanced fertilizer every few weeks during the growing season to ensure your tree is getting the necessary nutrients.

Monitor the new growth and overall health of the tree. If you notice any additional symptoms or if the browning worsens, let us know, and we can dive deeper into troubleshooting! Good luck, and I hope your mango tree thrives!
