Hi everybody,
My BOP (strelitzia augusta) seems to be suffering a lot.
I bought it 1 month ago and initially I kept it in his pot waiting for the new one to arrive.
During the first week I didn't water it because the soil was still wet. Afterwards, brown spots appeared on the leaves, so I thought it might be suffering from diseases and fungus and I spayed the leaves with Cobre fungicide for 1 week.
After that, I watered a little with a solution of amino acids rich in zinc and manganesium, green plant fertilizer and chelated iron. I think I generated the burn from too many chemicals because the leaves curled inwards and the edges became very dry and burnt, and for this reason, after 2 weeks from the purchase, I thought it was time to water my plant, and with the intention of cleaning the soil from the chemicals I watered for two days until the water came out of the holes and replaced the surface soil.
Afterwards, I did not water because the soil was still wet, but I moistened the leaves constantly (5/7 times a day).
The plant is currently outdoors, the temperature during the day is about 18/19C degrees and at night 11 degrees.
It receives 2 hours of direct sunlight from 3pm to 5pm and I'm also noticing that it doesn't like the sun that much (I haven't figured out yet if the strelitzia augusta loves the sun, does it? ) since the edges of the leaves burn faster after sunbathing.
White spots are now coming out on the leaves and they are turning a bit yellowish, while the stems gots some brown spots. I checked with the torch and I don't think there are any mites (the small white spots you see in the picture are small residues of fungicide).
What can I do to save the plant? I have already shaped the leaves by cutting the burnt edges, hoping this will help it revive .
Do you think there is any chance it can be saved?
Thank you so much
