My mango seedling is lately getting brown curly leaves and dropping them, what could be the reason of this, I give it water when the soil is getting dry (aprox every 3-4 days).

The most upper leaves started first and it looks like it is slowly creeping to the lower leaves.

Could it be an illness of anything? Would it be possible to save it still or would it be to late? I also think the plant is not realy growing anymore.

The soil is just potting soil without any special thing added.

  • If the leaf symptoms persist beyond the mites, I might suspect that the mites spread a disease, such as Verticillium or Fusarium, to the tree. Finding out if you have either of those diseases (even if it's outdoors) in your area would be helpful for probable diagnosis. Commented Nov 5, 2022 at 19:15
  • The tree has lately not been outside, only when it was summer, right now its way to cold for the plant to survive outside in my country. As far I know no other plants inside have the same issue.

Mango plants need regular watering, Make sure you're watering your mango plant appropriately, allowing the soil to dry out slightly between watering.

Mango plants require plenty of sunlight to thrive, make sure that your plant is placed in a location where it can receive bright, indirect sunlight for each day.

Yellowing leaves can signal a nitrogen deficiency, while weak stems or slow growth might point to a lack of phosphorus. Consider fertilising your plant with a balanced fertiliser specifically formulated for fruit trees.

Transplant Shock leading to leaf drop, give the plant some time to acclimatise to its new environment.

I observe webs on your plant and this makes me think the problem is spider mites. Spider mites and aphids are the pests causing leaves to droop. Insecticidal soap and neem oil are your go-to for pest control.

If you're not sure about the causes of the leaf drop or how to cure it, consulting with a gardening expert or a local nursery may be helpful.

    Thanks for your reply, it is quite some time ago now, the tree managed to survive and is making new leaves still.

I see webs on the stems and this makes me think the problem is spider mites. I suggest an immediate bath in soap and water repeated at least twice at five day intervals.

Fill a sink or bucket with 5 ml dish soap and a liter or more of water. Dip the plant in, wait a minute for the soap to clog the spiracles of any insects and rinse with clean water.

  • I will try this, do you think the plant has a chance of surviving? also how can I prevent those insects to place themselves on my tree, or is this a thing that is inevitable
