I bought a coconut plant 4 days ago. It was kind of healthy when I bought it. But today I noticed that the leaves are brown and it seems something is wrong with it.
- I have watered it once yesterday (0,8 liter).
- I have sprayed neem oil on the leaves yesterday.
- I mist it regularly.
- During the daytime I kept it on the balcony with direct sun exposure with temperatures above 20 degrees. We had 43% humidity (Germany). Before sunset I moved it inside with humidity above 40% and temperature above 20.
Can the long sun exposure be the problem?
Do I need to water it more? (note that the soil is still wet)
Did the neem oil with sun cause this issue ?
Note that I bought 3 coconut plants in total and the other two are also turning brown, but slower. Any help to save it would be appreciated. Also want to know what’s wrong to avoid the same issue with the other two plants.
